AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

The SAMREC/JORC definition of a Mineral Resource is

as follows:

A Mineral Resource is a concentration or occurrence of material of

intrinsic economic interest in or on the earth’s crust in such form,

quality and quantity that there are reasonable prospects for eventual

economic extraction. The location, quantity, grade, geological

characteristics and continuity of a Mineral Resource are known,

estimated or interpreted from specific geological evidence and

knowledge. Mineral Resources are sub-divided, in order of increasing

geological confidence, into Inferred, Indicated and Measured

categories.

The Mineral Resource is estimated using all drilling and sampling

information along with a detailed geological model. The geological

models are based on core logging, mapping, geophysics,

geochemistry and geological understanding that have been developed

for each deposit. Most of the AngloGold Ashanti deposits have been

the subject of research by world experts in the class of gold deposit.

The grade estimation for each deposit has been developed over the

life of the mine and is constantly reviewed in terms of grade control

information and reconciliation with the metallurgical plant. In general,

the deep South African mines utilise a process of compound log

normal macro kriging for the estimation of the Mineral Resource, while

the open pits and shallow underground mines generally use

recoverable Mineral Resource models, estimated using uniform

conditioning or multiple indicator kriging.

In order to comply with the economic requirement of the definition of

a Mineral Resource, all AngloGold Ashanti Mineral Resources are

constrained at an upside gold price, with all other parameters being

kept the same as used for estimation of the Ore Reserve. In the

underground gold mines, scoping studies are conducted on all

coherent blocks of ground that lie above the calculated Mineral

Resource cut-off. These studies include all cost and capital

requirements to access the block. In the case of open-pit operations,

pit optimisations are conducted at the Mineral Resource gold price

and all material outside these shells is excluded from the Mineral

Resource, unless it is potentially mineable from underground.

It is the opinion of AngloGold Ashanti that the Mineral Resource

represents a realistic view of an upside potential to the Ore Reserve. In

interpreting the Mineral Resource it is critical to factor in the following:

(i)

The Mineral Resource is quoted in situ and has not been

corrected for dilution, mining losses or recovery.

(ii)

The Mineral Resource includes a high percentage of Inferred

material, which, following further exploration drilling may be

converted to an Indicated or Measured Mineral Resource.

(iii)

Many of the areas lying in the exclusive Mineral Resource are

currently being actively drilled and are the subject of economic

and technical studies. It can, however, not be assumed at this

stage that the company has intent to mine these areas.

Mineral Resources definitions

Mineral Resource

Mineral Resource classification is based on the '15% Rule'. A

Measured Mineral Resource should be expected to be within 15% of

the quarterly metal estimate at least 90% of the time, while for an

Indicated Mineral Resource estimate the annual metal estimate should

be within 15% of the metal estimated at least 90% of the time. For an

Inferred Mineral Resource the annual error may for 90% of the time, be

greater than 15%.

The process and methodology of classification are at the discretion of

the competent person and involve expressing the '15% Rule' as a

required level of information, in tangible terms, the spacing of the drill-

hole or tunnel spacing in a particular deposit. Techniques such as

conditional simulation or even an empirical reconciliation-based

approach are employed. However, all operations are responsible for

demonstrating, through reconciliation, that their classification system

conforms to the 15% rule set out above.

AngloGold Ashanti quotes its Mineral Resource as inclusive of the Ore

Reserve. However, in this document the exclusive Mineral Resource is

also quoted. The exclusive Mineral Resource is defined as the inclusive

Mineral Resource less the Ore Reserve before dilution and other

factors are applied. The exclusive Mineral Resource consists of the

following components:

Inferred Mineral Resource within the optimised shell;

Other Inferred Mineral Resource;

Measured and Indicated Mineral Resource that lies between the life

of mine (LOM) pit shell/mine design and the Mineral Resource pit

shell. This material will become economic if the gold price increases;

and

Mineral Resource where the technical studies to engineer an Ore

Reserve have not yet been completed.

Ore Reserve

The SAMREC/JORC definition of an Ore Reserve is

as follows:

An Ore Reserve is the economically mineable part of a Measured

and/or Indicated Mineral Resource. It includes diluting materials and

allowances for losses, which may occur when the material is mined.

Appropriate assessments and studies have been carried out, and

include consideration of and modification by realistically assumed

mining, metallurgical, economic, marketing, legal, environmental,

social and governmental factors. These assessments demonstrate at

the time of reporting that extraction could reasonably be justified. Ore

Reserves are sub-divided, in order of increasing confidence, into

Probable Ore Reserves and Proved Ore Reserves.

In the underground operations, Ore Reserves are based on a full mine

design and in the case of open pits, on a pit optimisation followed by

a final pit design. Ore Reserves are reported according to tonnage,

mean grade(s), contained metal inclusive of mining dilution, mining ore

losses and mine call factors. These modifying factors are based on

measurements, rather than estimates. Tonnage and grade estimates

for surface stockpile materials that meet Ore Reserve criteria are

itemised separately.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Only those Ore Reserves included for treatment in the business unit

plan production schedule are considered in the Ore Reserve

statement. These plans sometimes include marginal or sub-grade ores

as well as Inferred Mineral Resources. These Inferred Mineral

Resources are not included in the Ore Reserve statement.

For new projects, an Ore Reserve is only reported if an auditable pre-

feasibility or feasibility study has been completed that demonstrates

the viability of the project and meets the company’s investment

requirements. There should also be intent on the part of the company

to proceed to feasibility and ultimately a mining phase.

Traditional sensitivity studies are not applied to the Ore Reserve.

Instead, the cash flow for each operation is tested using gold prices

near to the average gold price for the preceding three years. Gold

prices of US$577 and US$600/oz were used. In all cases, except for

Tau Lekoa, the operations remained cash flow positive albeit at a

reduced margin. In the case of Tau Lekoa, the Ore Reserve dropped

from 1.3 million ounces to 0.4 million ounces at US$577/oz.

Mineral Resources definitions continued

Mineral Resources and Ore Reserves

Mineral Resources

The 2007 Mineral Resource increased by 34.1 million ounces before

the subtraction of depletion. After a depletion of 8.1 million ounces, the

net increase is 26.1 million ounces to give a total Mineral Resource of

207.6 million ounces. Mineral Resources were estimated at a gold

price of US$700 per ounce in contrast to the US$650 used in 2006.

The increased gold price resulted in 17.5 million ounces of added

Mineral Resource while successful exploration and revised modelling

resulted in a further increase of 14.2 million ounces. The remaining

change of 2.5 million ounces is the result of various other reasons.

Mineral Resources and Ore Reserves are reported in accordance with the minimum

standard described by the Australasian Code for Reporting of Exploration Results,

Mineral Resources and Ore Reserves (The JORC Code, 2004 Edition), and also

conform to the standards set out in the South African Code for the Reporting of

Mineral Resources and Mineral Reserves (the SAMREC 2000 Code). Mineral

Resources are inclusive of the Ore Reserve component unless otherwise stated.

The 2007 Ore Reserve increased by 13.0 million ounces before the

subtraction of depletion. After a depletion of 6.8 million ounces, the net

increase is 6.2 million ounces to give a total Ore Reserve of 73.1 million

ounces.

A gold price of US$600 was used for Ore Reserve estimates in

contrast to the US$550 used in 2006. The change in economic

assumptions made from 2006 to 2007 resulted in the Ore Reserve

increasing by 6.3 million ounces while exploration and modelling

resulted in an additional increase of 6.7 million ounces.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

South Africa operations: overview

The Vaal River operations consist of Great Noligwa, Kopanang, Tau

Lekoa and Moab Khotsong mines. The primary reefs in this region are

the Vaal Reef (VR) and the Ventersdorp Contact Reef (VCR) and the

secondary reef mined is the Crystalkop Reef (C Reef).

The West Wits operations are made up of Mponeng, Savuka and

TauTona and these mines are situated near the town of Carletonville.

The primary reefs mined are the Carbon Leader Reef (CLR) and VCR.

All seven operations are 100% owned by AngloGold Ashanti. In

addition, the Vaal River Surface and West Wits Surface operations

consist of the reprocessing of waste rock dumps and tailings dams

resulting from the mining of the primary and secondary reef horizons.

The South African operations are all located in the rocks of the famous

Witwatersrand Basin, which is regarded as the greatest gold-bearing

repository on Earth.

Geology of the Witwatersrand Basin

The Witwatersrand Supergroup (deposited in the area often described

as the Witwatersrand Basin) comprises a six-kilometre thick sequence

of predominantly argillaceous and arenaceous sediments that extend

laterally for some 300km north-east/south-west and 100km north-

west/south-east on the Kaapvaal Craton. The upper portion of the

sequence contains the laterally-extensive, gold-bearing quartz pebble

conglomerate horizons or reefs.

Further west, south and east the basin is overlain by up to four

kilometres of Archaean, Proterozoic and Mesozoic volcanic and

sedimentary rocks. The Witwatersrand Basin is late Archaean in age

and is considered to be around 2.7 billion to 2.8 billion years old.

The reefs, which are generally less than two metres thick, are widely

considered to represent laterally extensive braided fluvial deposits.

Separate fan systems were developed at different entry points and

these are preserved as distinct goldfields with local geological

variations. AngloGold Ashanti operates in two of these goldfields,

known as the Carletonville (West Wits) and Klerksdorp (Vaal River)

Goldfields.

There is still much debate about the origin of the gold mineralisation in

the Witwatersrand Basin. Gold was generally considered to have been

deposited syngenetically with the conglomerates, but increasingly an

epigenetic theory of origin is being supported. Nonetheless, the most

fundamental determinant of gold distribution in the basin remains the

sedimentary features, such as facies variations and channel directions.

Gold generally occurs in native form often associated with pyrite and

carbon, with quartz being the main gangue mineral.

West Wits (Mponeng, Savuka and TauTona operations)

Two reef horizons are exploited at the West Wits operations: the VCR,

located at the top of the Central Rand Group, and the CLR near the

base. The separation between the two reefs increases from east to

west, from 400m to 900m, due to the non-conformity of the VCR with

the underlying strata. TauTona and Savuka exploit both reefs, while

currently Mponeng only mines the VCR. The CLR Project has been

published as a reserve and Mponeng will eventually mine both reefs.

The structure is relatively simple, with rare instances of faults displaying

greater than 70m of displacement.

The CLR consists of one or more conglomerate units and varies from

several centimetres to more than three metres in thickness. Regionally,

the VCR dips at approximately 21°, but may vary between 5° and 50°,

accompanied by changes in thickness of the conglomerate units.

Where the conglomerate has the attitude of the regional dip, it tends

to be thick, well-developed and accompanied by higher gold

accumulations. Where the attitude departs significantly from the

regional dip, the reef is thin, and varies from several centimetres to

more than three metres in thickness.

Vaal River (Great Noligwa, Kopanang, Moab Khotsong
and Tau Lekoa operations and Vaal River Surface
Rock Dumps)

In order of importance, the reefs mined at the Vaal River operations are

the VR, the VCR and the C Reef:

the VR contains approximately 85% of the reserve tonnage with

mining grades of between 10g/t and 20g/t gold and comprises a

series of oligomictic conglomerates and quartzite packages

developed on successive non-conformities. Several distinct facies

have been identified, each with its own unique gold distribution and

grade characteristic;

the VCR has a lower gold grade than the VR, and contains

approximately 15% of the estimated Ore Reserves. The economic

portion is concentrated in the western part of the lease area and

can take the form of a massive conglomerate, a pyritic sand unit

with intermittent pebble layers, or a thin conglomerate horizon. The

reef is located at the contact between the overlying Kliprivierberg

Lavas of the Ventersdorp Super Group and the underlying

sediments of the Witwatersrand Super Group, which creates a

distinctive seismic reflector. The VCR is located up to one kilometre

above the VR; and

the C Reef is a thin, small-pebble conglomerate with a carbon-rich

basal contact, located approximately 270m above the VR. It has

less than 1% of the estimated Ore Reserves with gold grades

similar to those of the VR, but less continuity. The most significant

structural features are the north-east striking normal faults which dip

to the north-west and south-east, resulting in zones of fault loss.

Mineral Resource estimation

A multi-disciplinary approach is adapted to Mineral Resource

estimation whereby inputs are required from the geology, survey, mine

planning and evaluation departments. A computerised system called

the Mineral Resource Inventory System (MRIS) integrates all the input

information to produce the final Mineral Resource per operation. The

Mineral Resource estimates are computed from a composite grid of

value estimates, comprising various block sizes. The macro block

sizes vary from 210m x 210m to 420m x 420m and the micro blocks

comprise of 30m x 30m blocks.

Compound lognormal macro co-kriging estimation techniques are

used to produce estimates for the larger block sizes. This technique

uses the Bayesian approach whereby the assayed (observed) data in

the mined-out areas are used to infer the population characteristics of

the area ahead of current mining. The geological model forms the basis

for this estimation and all surface borehole information from the

peripheral areas of the mine lease play a crucial role in determining the

geological model boundaries. Simple kriging is used for the 30 metre

block sizes and these estimates are constrained by the kriging variance.

The Mineral Resources are initially reported as inclusive of Ore

Reserves as they form the basis for the Ore Reserve conversion

process. Mineral Resource cut-offs are computed by operation, for

each reef horizon. These cut-offs incorporate a profit margin that is

relevant to the business plan. Mineral Resource grade tonnage curves

are produced for the individual operations, which show the potential of

the orebody at different cut-offs. These curves are produced for

dimensions equivalent to a practical mining unit for underground

operations.

Exclusive Mineral Resource

The exclusive Mineral Resource is defined as the inclusive Mineral

Resource minus the in-situ Ore Reserve before stoping width, dilution

and mine call factors are applied. Scoping studies are conducted on

this exclusive Mineral Resource, where capital requirements and

current costs are used to test economic potential. If these studies

show no reasonable economic potential at the Mineral Resource gold

price then the material is excluded from the Mineral Resource. All

planned pillars (ahead of current mining) form part of the exclusive

Mineral Resource.

Ore Reserve estimation

All mine designs are undertaken using the Cadsmine

each mining level and section, usually leading from an extension to the

existing mining sequence, and the definition of the necessary

development layouts. The in-situ Mineral Resource is scheduled

monthly for the full LOM plan. The value estimates for these schedules

are derived directly from MRIS.

Modifying factors are applied to the in-situ Mineral Resource to arrive

at an Ore Reserve. These factors comprise a dilution factor to

accommodate the difference between the mill width and the stoping

width as well as the Mine Call Factor (MCF).

1. Where no dilution factor is indicated the dilution is inherent in the resource model estimate.
* Dilution: The difference between the tonnage broken in stopes and the tonnage milled from underground sources. For example, if 100 tonnes broken in

the stopes amounts to 132 tonnes milled, then the dilution is 32%.

** Mine Call Factor (MCF): The ratio expressed as a percentage, which the specific product accounted for in the recovery, plus residues, bears to the

corresponding product called for by the mine’s measuring methods.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

AngloGold Ashanti produces uranium oxide concentrate (U3O8) as a

by-product from its South African gold mining operations. AngloGold

Ashanti currently produces between 550 and 650 tonnes of

U3O8 annually, with the potential to increase this to 1,000 tonnes by the

year 2012.

Although mined as a by-product of gold for many years, U3O8 was not

considered a resource until the year 2005. Due to the rapid increase in

the U3O8 price over the last few years, renewed focus has been placed

on the U3O8 content within the Witwatersrand reefs with the result that

in 2005 uranium was reported for the first time as a fully SAMREC

compliant resource.

The AngloGold Ashanti mines in the Vaal River region that currently

produce uranium oxide as a by-product are Great Noligwa, Kopanang

and Moab Khotsong. The uranium oxide is extracted from the VR,

although Great Noligwa mine also produces some uranium oxide from

the C Reef. The mines in the West Wits region that have uranium

resources are Mponeng, Savuka and TauTona and in this mining

region the uranium is extracted from the CLR.

The surface tailings storage facilities that have been classified as

uranium resources are the Kopanang Pay dam and the tailings storage

facilities in the West Wits region.

Uraninite and brannerite are the most common uranium bearing

minerals, although uraniferous leucoxene and coffinite are also

present. Uraninite was the original primary uranium bearing mineral

and was possibly introduced as detrital material during the deposition

process of the Witwatersrand sediments.

Great Noligwa

Great Noligwa is located about 15km south-east of the town of

Orkney, in the southern part of the Klerksdorp Goldfield. The mine

exploits the VR at depths varying between 1,500m and 2,800m below

surface. Scattered mining methods are employed where access to the

reef is from the footwall haulage and return airway development, with

cross-cuts developed every 180m to the reef horizon. Raises are then

developed on-reef to the level above and the reef is stoped out on

strike. The Great Noligwa lease area is constrained to the north by

Harmony’s Orkney 2 Shaft, to the east by Buffelsfontein Gold Mine, to

the south by the Jersey and Die Hoek faults, (which displace the reef

down by approximately 1,000m and 900m respectively), and to the

west by Kopanang Mine.

Geology

The VR is the principal economic horizon at Great Noligwa Mine,

accounting for over 90% of the gold produced at the mine. The VR is

part of the Witwatersrand Supergroup and is stratigraphically located

near the middle of the Central Rand Group in the

Johannesburg Subgroup on an unconformity below the Krugersdorp

Formation. The VR unit can reach a maximum thickness of over two

metres and consists of a thin basal conglomerate (the C Facies) and a

thicker sequence of upper conglomerates (the A Facies), separated by

internal quartzite (the B Facies). Across most of the Great Noligwa

lease area, the A Facies is the principal economic horizon within the

VR, although sporadic remnants of C Facies may be preserved below

the A Facies.

The C Reef has been mined on a limited scale in the central part of

Great Noligwa mine, where a high-grade, north-south orientated

channel containing two economic horizons has been exposed. To the

east and west of this channel the C Reef is poorly developed with

relatively small areas of economic interest. High uranium values in the

C Reef are often associated with high gold values. To the north the

C Reef sub-crops against the Gold Estates Conglomerates, and in the

extreme south of the mine the C Reef has been eliminated by a deeply

eroded Kimberley Channel and the Jersey fault.

South Africa operations: Kopanang

Kopanang

Kopanang mine is located about 10km south-east of the town of

Orkney, in the southern part of the Klerksdorp Goldfield. The mine

exploits the VR at depths varying between 1,300m and 2,200m below

surface. The C Reef is a secondary reef that occupies a stratigraphic

horizon about 260m above the VR. Scattered mining methods are

employed.

Geology

The VR is the principal economic horizon on Kopanang, accounting for

over 95% of the gold mined. The VR is part of the Witwatersrand

Supergroup and is stratigraphically located near the middle of the

Central Rand Group in the Johannesburg Subgroup on an

unconformity below the Krugersdorp Formation. The VR package

can reach a maximum thickness of over two metres and consists of a

thin basal conglomerate (the C Facies) and a thicker sequence of

upper conglomerates (the A Facies), separated by internal quartzite

(the B Facies). Across most of the Kopanang lease area only the basal

C Facies is mined.

The C Reef has been mined on a limited scale in the central parts of

Kopanang, where the gold and uranium values are generally lower

than the VR. The C Reef sub-crops in the north against the Gold

Estates Conglomerates, and is eliminated in the south by younger,

deeply eroded Kimberley Channels. The C Reef also contains two

economic conglomerates, although the lowermost conglomerate is

only preserved as small remnants.

Moab Khotsong

Moab Khotsong, which is still in development, lies to the south of and

is contiguous with the lease area of Great Noligwa. The Mineral

Resource at Moab Khotsong is structurally complex and highly faulted,

with large fault-loss areas. Mining is based on a backfill system

combined with bracket pillars. The raise lines are spaced 200m apart

on the dip of the reef, with 25m-long panels. Backfill is carried to within

four metres of the advancing stope faces and 75% of the total area

extracted is likely to be backfilled.

Geology

The Mineral Resource lies between 2,100m and 3,700m below surface,

with only limited quantities of ore lying above 2,300m. The principal reef

is the VR, as a down-dip extension to the south and south-east of the

orebody mined at Kopanang and Great Noligwa mines. The reef is

represented by an oligomictic conglomerate and the gold

mineralisation is associated with carbon. The VR package can reach

a maximum thickness of over two metres and consists of a thin

basal conglomerate (the C Facies) and a thicker sequence of

upper conglomerates (the A Facies), separated by internal

quartzite (the B Facies). The C Reef is preserved in the northern part

of the mine where the reef has been intersected by a number of

boreholes. No development or stoping has taken place on the C Reef

at Moab Khotsong.

South Africa operations: Moab Khotsong

Project Zaaiplaats 2

Project Zaaiplaats 2 (PZ2) is situated at Moab Khotsong in the Vaal

River Region of AngloGold Ashanti’s South African operations. Moab

Khotsong is the newest mine in the region and the PZ2 project is

aimed at optimally extracting the deeper portion (lower mine) of the VR

at Moab Khotsong.

Investigations into extracting this block of ground have been underway

for several years but unfavourable market conditions have delayed the

initiation of mining in this deeper block of ground (up to 3,500m below

surface). The PZ2 project is planned to extend the life of Moab

Khotsong for another 25 years until the mid 2030’s. The project also

allows other opportunities (mining and metallurgical) to come to the

fore that would otherwise have been uneconomic.

The orebody is accessed through twin double-declines angled at 8º,

the upper and lower declines, from which five production levels will

originate. These will allow two attacking points into the orebody, as

well as provide sufficient ventilation capacity. One of the lower declines

will be a dedicated ore-handling system via a conveyor belt; each of

the decline sets will have a dedicated men and material decline using

chairlifts and a monorail; and the remaining upper decline will carry the

majority of the services into the orebody. Shaft bottom will be situated

at 4,027m below datum (3,509m below collar).

It is estimated that there are currently 3.5 million ounces of Ore

Reserves within the orebody of the lower mine area. Further

opportunities exist around the main block, but additional exploration

will be required before these reserves can be published.

Brownfields exploration

Brownfields exploration is currently focused on improving geological

confidence in:

the eastern, western and northern boundaries of the upper mine

block;

the internal structure of the upper mine block; and

the lower mine block (Project Zaaiplaats 2).

Surface borehole MGR7 was completed during the year and the

original cluster had a value of 715 cm.g/t over 46.4 cm whilst the long

deflection cluster had a value of 1,474 cm.g/t over 79.2 cm. A long

deflection was drilled from LIB13 and confirmed the location of both

the cut-off and MKF1 faults and also indicated the presence of a large

block of ground between 95 and 101 levels. LIB 9 commenced drilling

from 92 level to test the structure interpretation between surface

boreholes CY1 and MCY2 and is currently still in progress. The four

surface boreholes and one LIB hole (MCY4, MCY5, MZA9, MMB5 and

LIB9) are currently in progress and it is planned to commence with two

further LIB holes (LIB4 and LIB10) in the new year.

South Africa operations: Tau Lekoa

Tau Lekoa mine is located about 8km west of the town of Orkney, at

the western extreme of the Klerksdorp Goldfields. The mine exploits

the VCR at depths varying between 900m and 1,700m below

surface. The VCR is the only reef exploited at Tau Lekoa and dips

towards the west at an average angle of 30°. Tau Lekoa has a twin

shaft system and mines to a depth of 1,650m. Tau Lekoa uses

hydropower which has a centralised electro-hydraulic system as its

primary source of energy production. Hydropower has been

instrumental in improving labour productivity, which has played a vital

role in assisting the mine to achieve its business objectives.

Geology

The VCR is a gold bearing quartz pebble conglomerate (up to 5m

thick) capping the uppermost angular unconformity of the

Witwatersrand Supergroup. The topography of the VCR depositional

area is uneven, and consists of a series of slopes and horizontal

terraces at different elevations. The VCR is deposited over a number

of terraces that are separated by slope material. Typically the terrace

reef is a thicker, more robust conglomerate unit than the slope

material, where hangingwall-footwall conditions may occur. The

deepest terraces are the youngest, whereas the oldest terrace

occupies a topographical horizon 28m above the youngest terrace.

Generally the younger the terrace, the more mature the channel fill.

The main channel is the youngest, most mature VCR facies at Tau

Lekoa, and extends from the northeast into Tau Lekoa, before

turning sharply towards the west. The older middle and upper

terraces contain more immature conglomerates with more erratic

gold grades.

The Exclusive Mineral Resource is sensitive to the gold price and a large portion of this Mineral Resource is due to the difference in

Mineral Resource and Ore Reserve gold prices. Approximately 20 to 25% of the exclusive Mineral Resource is expected to occur in safety

and remnant pillars ahead of current mining.

Mponeng lies on the West Wits Line, close to Carletonville in the

Gauteng Province and about 65km south-west of Johannesburg.

Mining at Mponeng is conducted at an average depth of 2,800m. The

mine operates two vertical hoisting shafts, a sub-shaft and two service

shafts. The Mponeng lease area is constrained to the north by TauTona

and Savuka, but is constrained only by the depth of the ore-body,

which is open-ended, towards the south.

Geology

The VCR is the only reef that is currently being mined at Mponeng. The

VCR comprises of a quartz pebble conglomerate (up to 3m thick)

capping the topmost angular unconformity of the Witwatersrand

Supergroup. The footwall stratigraphy partially controls the reef type.

Most of the VCR mined lies on footwall strata of the Kimberley

Formation, which is relatively argillaceous. More durable quartzites of

the Elsburg Formation lie to the west, while the eastern side of the

mine is dominated by the Booysens Shale.

Mponeng is also planning to mine the CLR. The CLR at Mponeng is

on average a 20cm thick, tabular, auriferous quartz pebble

conglomerate formed near the base of the Central Rand Group. The

CLR is deeper than the VCR and currently there is an exploration

programme drilling to improve resource confidence and confirm

geological structures that occur at the lower levels. Of the three

economic units that exist for the CLR, the Mponeng CLR target area

is dominated by Unit 3 with a smaller portion of Unit 2 towards the

east. Unit 2 is a complex channel deposit, and Unit 3 is the oldest of

the CLR channel deposits sitting at the base of the package.

Two economically viable reefs are mined in the West Wits area, the

shallower VCR, and the deeper CLR. Both have been extensively

mined at AngloGold Ashanti’s TauTona and Savuka Mines, whilst

Mponeng has only mined the VCR. Both reefs can be accessed down

to 120 level (3,645m below datum), but there is currently no

infrastructure in place that can service stoping operations below

120 level.

Mponeng is in a prime position to exploit the CLR, and had in fact

originally been designed with this in mind via its sub-shaft deepening

project which commenced in the mid-1990’s. Due to economic factors

at the time, this sub-shaft was stopped at 120 level in 2000 and is now

being used to service the VCR mining operations.

The high-grade CLR below 120 level has remained inaccessible and

this represents an enormous opportunity for Mponeng and for

AngloGold Ashanti. A project team has been set up to design a “new

mine” with the ability to access the CLR via tertiary shafts from

Mponeng, enabling the mine to extend its life until at least 2040, and

producing gold at its current levels.

The mine has been designed according to the Sequential Grid mining

method, a technique developed at Elandsrand and Mponeng in the

1990’s whereby stoping grids are pre-developed and reef extracted

between dip-stabilising pillars. This method has proved successful in

the management of seismicity, both from an overall reduction in

seismic energy perspective, as well as from an increased mining

flexibility view point. The shafts and infrastructure have been designed

to fit the existing shaft system at Mponeng, and have the ability to

sustain high levels of production.

The extension of Mponeng via the Carbon Leader Reef Project

provides a strong base on which several regional benefits can be

realised, as well as enabling other smaller projects to be brought in to

match the extended life of the asset and region.

Savuka

The Savuka mine is located about 18km south of the town of

Carletonville, in the West Wits Goldfields. The mine exploits the CLR

at depths varying between 2,600m and 3,500m below surface. The

VCR, which on average is about 700m above the CLR is also

exploited at Savuka, but to a lesser extent than the CLR. A

combination of mining methods is used: longwall, conventional and

sequential grid mining.

Geology

The CLR is a thin, on average 20cm thick, tabular, auriferous quartz

pebble conglomerate formed near the base of the Central Rand

Group. The CLR has been divided into three stratigraphic units.

Economically the most important unit is Unit 1 which is present as a

sheet-like deposit over the whole mine. Unit 2 is a complex channel

deposit that is only present along the western most limit of the

current mining at Savuka. The reef may be over two metres thick

where Unit 2 is developed. Unit 3 is preserved below Unit 1 in the

southern parts of Savuka and is the oldest of the CLR conglomerates.

Production levels on the VCR at Savuka are not as high as on the CLR,

with about 15% to 20% of the tonnage coming from the VCR. The

VCR comprises of a quartz pebble conglomerate (up to 5m thick)

capping the topmost angular unconformity of the Witwatersrand

Supergroup. The topography of the VCR depositional area is uneven,

and consists of a series of slopes and horizontal terraces at different

elevations. It sub-outcrops against the base of the Ventersdorp Lavas

in a direction parallel to strike across the north-western part of the

lease area.

The exclusive Mineral Resource is sensitive to the gold price and a large portion of this Mineral Resource is due to the difference in Mineral Resource

and Ore Reserve gold prices. Approximately 40% of the exclusive Mineral Resource is expected to occur in safety and remnant pillars ahead of

current mining.

South Africa operations: Savuka continued

South Africa operations: TauTona

TauTona lies on the West Wits Line, close to Carletonville in Gauteng

and about 70km south-west of Johannesburg. Mining at TauTona

takes place at depths ranging from 1,800m to 3,500m, where the

world’s deepest stoping section is found. The mine has a main shaft

system as well as a secondary and a tertiary shaft. It is predominantly

a long-wall operation.

Geology

The CLR is a thin, on average 20cm thick, tabular, auriferous quartz

pebble conglomerate formed near the base of the Central Rand

Group. The CLR has been divided into three stratigraphic units.

Economically the most important unit is Unit 1, which is present as a

sheet-like deposit over the whole mine, although the reef development

and grades tend to drop off very rapidly where Unit 1 overlies Unit 2.

Unit 2 is a complex channel deposit that is only present along the

easternmost limit of the current mining at TauTona mine. The reef may

be over two metres thick where Unit 2 is developed. Unit 3 is

preserved below Unit 1 in the southern parts of TauTona and is the

oldest of the CLR conglomerates.

Production levels on the VCR at TauTona are currently limited,

amounting to less than 10% of total production volumes. The VCR

comprises of a quartz pebble conglomerate (up to 5m thick) capping

the topmost angular unconformity of the Witwatersrand Supergroup.

The topography of the VCR depositional area is uneven, and consists

of a series of slopes and horizontal terraces at different elevations.

The Mineral Resource estimates are computed using the relevant

computer modules of Datamine®software package. The geological

model is a critical input to the Mineral Resource estimation process. The

orebody boundaries for each geological entity (veins, stock work, wall

rock) are defined from the detailed logging of all geological bore holes

and after validation this information is used in the system to create a

three dimensional model. This model is subsequently populated with a

5 x 25 x 5m (X by Y by Z) block model. The block sizes used are chosen

to represent the dimensions in which the deposit is intended to be

mined. Volumetric measurements of the orebody are subsequently

computed in the system using the relevant block dimensions.

Ordinary kriging is used to perform the grade interpolation. Field tests

are conducted to determine appropriate in-situ densities. The mining

of a specific area of the orebody is surveyed and an accurate

measurement of the corresponding mass associated with the mining

area is recorded. The in-situ density is then computed by dividing the

mass by the surveyed volume. Using the volume, grade and density

information, the Mineral Resource estimates are computed for the

individual orebodies.

Ore Reserve estimation

The appropriate Mineral Resource models are used as the basis for

Ore Reserves. All relevant modifying factors such as mining dilution

and costs are used in the Ore Reserve conversion process. This is

based on the original block grades and tonnage and includes waste

material (both internal and external). Appropriate Ore Reserve cut-off

grades are applied and all blocks above this cut-off are reported. For

the reserve optimisation, Whittle®software was used and Datamine®

software was utilised to design the pits.

Argentina operations: Cerro Vanguardia

Cerro Vanguardia

The Cerro Vanguardia property is located 160km north-west of Puerto

San Julian. The property is situated within the southern Deseado Masive.

Geology

The oldest rocks in this part of Patagonia are of Precambrian-

Cambrian age. These are overlain by Permian and Triassic continental

clastic rocks which have been faulted into a series of horsts and

grabens, and are associated with both limited basaltic sills and dykes

and with calc-alkaline granite and granodiorite intrusions. Thick

andesite flows of Lower Jurassic age occur above these sedimentary

units. A large volume of rhyolitic ignimbrites was emplaced during the

Middle and Upper Jurassic age over an area of approximately

100,000km

. These volcanic rocks include the Chon Aike formation

ignimbrite units that host the gold-bearing veins at Cerro Vanguardia.

Post-mineral units include Cretaceous and Tertiary rocks of both

marine and continental origin, the Quaternary La Avenida formation,

the Patagonia gravel and the overlying La Angelita basalt flows. These

flows do not cover the area of the Cerro Vanguardia veins.

Gold and silver mineralisation at Cerro Vanguardia occurs within a

vertical range of about 150m to 200m, in a series of narrow, banded

quartz veins that occupy structures within the Chon Aike ignimbrites.

These veins form a typical structural pattern related to major north-

south (Concepcion) and east-west (Vanguardia) shears. Two sets of

veins have formed in response to this shearing one set strikes about

N40W and generally dips 65° to 90° to the east while the other set

strikes about N75W and the veins dip 60° to 80° to the south. They

are typical of epithermal, low-temperature, adularia-sericite character

and consist primarily of quartz in several forms as massive quartz,

banded chalcedonic quartz and quartz-cemented breccias. Dark

bands in the quartz are due to finely disseminated pyrite, now

oxidised to limonite. The veins show sharp contacts with the

surrounding ignimbrite, which hosts narrow stockwork zones that are

weakly mineralised, and appear to have been cut by a sequence of

north-east trending faults that have southerly movement with no

appreciable lateral displacement.

Ore Reserve estimation

The Ore Reserve is estimated by Lerch-Grossman pit optimisation

using the relevant Mineral Resource models and updated geotechnical

and metallurgical parameters and appropriate operating costs. The

recoverable gold Mineral Resource model has been estimated either

by a geostatistical technique called multiple indicator kriging or uniform

conditioning (non-linear geostatistical methods) and reflects the

selectivity or selective mining unit (SMU) of the mining equipment that

is intended to be used to recover the Mineral Resource within the Ore

Reserve pit design.

Modifying factors

The Boddington cut-off grade is formulated on a net revenue basis (Net

Smelter Return (NSR)) taking into account gold and copper grade/metal

price/recovery. The 0.32g/t COG approximates a life of mine cut-off

grade. This represents diorite material and using unit gold/copper prices

of A$750/oz and A$2.00/lb respectively. This NSR with gold leach and

gravity contributions cut-off grade is A$8.28/t and includes stockpile

rehandle mining cost of A$0.91/t thereby allowing for an elevated cut-

off grade strategy over the life of mine and inclusive of an end of mine

life rehandle cost.

Australia operations: overview continued

Australia operations: Boddington

Boddington

The operation is situated approximately 120km south-east of Perth in

Western Australia.

Geology

Boddington is located in the Archaean Saddleback greenstone belt in

the south-west of Western Australia. The main zone of gold

mineralisation occurs reasonably continuously over a strike length of

over 5km and a width of about 1km. The previous oxide operation,

which closed in 2001, produced approximately 6.1 million ounces

over a mine life of 15 years from a lateritic deposit developed over a

large basement Mineral Resource. This basement Mineral Resource,

beneath the oxide pits, is hosted predominantly by andesitic

volcanics and diorites, and contains both gold and copper

mineralisation. Construction of the 35.2 Mtpa basement treatment

plant is well advanced, with production anticipated to commence late

2008-early 2009.

Mineral Resource estimation

The Mineral Resource and Ore Reserve of the Boddington expansion

project have been updated as part of the annual evaluation process by

BGMMCo personnel. The geostatistical method of Uniform

Conditioning Is used to estimate the Mineral Resource All available

geological drill-hole information is validated for use in the models and

the local geology of the ore body is used to classify the drill-hole

information into appropriate geostatistical domains. Detailed statistical

analyses are conducted on each of these domains and this allows for

the identification of high grade outliers. If these values are anomalous

to the general population characteristics then they are cut back to the

appropriate upper limit of the population.

Grade tonnage information

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Australia operations: Sunrise Dam

Sunrise Dam lies some 220km north-northeast of Kalgoorlie and 55km

south of Laverton in Western Australia. The mine is 100% owned by

AngloGold Ashanti. The mine comprises a large open-pit operation

and an underground project. Mining is carried out by contractors and

ore is treated in a conventional gravity and leach process plant.

Geology

At Sunrise Dam gold mineralisation is structurally controlled and vein

hosted. The style of mineralisation can be differentiated depending on

the structure or environment in which it is hosted. There are three

dominant domains recognised:

(i)

Shear-related and high strain – e.g. Sunrise Shear Zone,

(ii)

Stock work development in planar faults with brittle

characteristics (these occur in all rock types and are commonly

concentrated at lithofacies contacts within the volcanic

stratigraphy or the porphyry margin and within hinge domains

within the magnetite shales) – e.g. Western Shear Zone, Watu,

Cosmo, Summercloud; and

(iii)

Placer-style mineralisation hosted within the fluvial sediments.

The vein and shear styles of gold mineralisation are introduced

primarily during the third and fourth deformation stages and variations

in structural style, ore and gangue mineralogy and alteration intensity

are observed locally. Secondary (supergene) gold mineralisation is also

an important part of the Cleo-Sunrise ore system and is highlighted by

extremely high gold grades developed near the base of tertiary

paleochannels and horizontal blankets of mineralisation related to iron

redox fronts and associated water tables.

Sunrise Dam

Mineral Resource estimation

open-pit estimates are generated using a geostatistical method called

multiple indicator kriging. All available geological drill-hole information is

validated for use in the models and the local geology of the ore body is

used to classify the drill-hole information into appropriate geostatistical

domains. Detailed statistical analyses are conducted on each of these

domains and this allows for the identification of high grade outliers. If

these values are anomalous to the general population characteristics

then they are cut back to the appropriate upper limit of the population.

Estimation for the underground Mineral Resources uses the geological

model boundaries to subdivide all drill-hole data into appropriate

domains. Statistical analyses are performed on these domains and in a

similar manner to that of open-pit estimation, high grade outliers are

identified and appropriately cut back to the upper limit of the population.

A geostatistical method called ordinary kriging is used to produce

estimates of a pre-determined block size. These block sizes are 10m x

10m and 20m x 20m. The geostatistical technique of Conditional

Simulation has been used to estimate the Cosmo ore zone.

Australia operations: Tropicana

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Tropicana

The Tropicana gold deposit is located approximately 350km north-

east of Kalgoorlie within the Great Victoria Desert, Western Australia.

Tropicana is the first deposit discovered in this remote greenfields

exploration area.

Geology

The Tropicana deposit comprises two known mineralised zones, the

Tropicana zone to the north and Havana zone to the south. Together

the known mineralised zones define a system that extends over a 4km

strike length. The lenses have been tested to a vertical depth of 350m

to 400m, and are open down dip. The Tropicana and Havana zones

are grossly “stratiform” within the preferred gneissic host sequence.

Havana zone consists of multiple stacked lenses, whereas Tropicana

comprises one main mineralised lens.

Mineral Resource estimation

The geostatistical method of Uniform Conditioning Is used to estimate

the Mineral Resource. All available geological drill-hole information is

validated for use in the models and the local geology of the ore body

is used to classify the drill-hole information into appropriate

geostatistical domains. Detailed statistical analyses are conducted on

each of these domains and this allows for the identification of high

grade outliers. If these values are anomalous to the general population

characteristics then they are cut back to the appropriate upper limit of

the population.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Brazil operations: Brasil Mineração

Brasil Mineração has mining rights over 30,698ha in the state of

Minas Gerais in south-eastern Brazil. The Brasil Mineração complex

is located in the municipalities of Nova Lima, Sabará and Santa

Bárbara, south and east of the city of Belo Horizonte and within the

mining district referred to as the Iron Quadrilateral (Quadrilátero

Ferrífero). This area hosts numerous historic and current gold mining

operations, as well as a number of open-pit limestone and iron ore

operations. Currently AngloGold Ashanti mines gold-bearing ore at

the Cuiabá underground mine and from the Córrego do Sítio heap-

leach mine.

Geology

Cuiabá mine, located in the municipality of Sabará, has gold

mineralisation associated with sulphides and quartz veins in Banded Iron

Formation (BIF) and volcanic sequences. Where BIF is mineralised, the

ore appears strongly stratiform due to the selective sulphidation of the

iron-rich layers. Steeply plunging shear zones tend to control the ore

shoots, which commonly plunge parallel to intersections between the

shears and other structures. The controlling mineralisation structures

are the apparent intersection of thrust faults with tight isoclinal folds in

a ductile environment. The host rocks at Brasil Mineração are BIF, and

mafic volcanics (principally basaltic). Mineralisation is due to the

interaction of low salinity carbon dioxide rich fluids with the high-iron

BIF, basalts and carbonaceous graphitic schists. Sulphide

mineralisation consists of pyrite and pyrrhotite with subordinate

arsenopyrite and chalcopyrite; the latter tends to occur as a late-stage

fracture fill and is not associated with gold mineralisation. Wallrock

alteration is typically carbonate, potassic and silicic. The Lamego

deposit is close to Cuiabá and the style of mineralisation is similar.

Some 30km to the south-east, the mineralised orebodies at Córrego do

Sítio are narrow NE-SW elongated lenses dipping at 20º to 30º and with

a pitch angle to the northeast. In general, the mineralised orebodies

comprise sericitic zones and quartz veinlets. The gold occurs as

inclusions (microscopic or sub-microscopic) in millimetre-size acicular

crystals of arsenopyrite, and also as intergrowths on the margins of the

sulphide. Other typical minerals in the orebodies are pyrrotite, pyrite and

chalcopyrite.

Three dimensional models of the BIF and sulphide orebodies are

created from the drill-hole data. Prototype block models of 10m x 10m

x 10m are used to quantify the volume of the orebody and ordinary

kriging is used as the geostatistical technique to interpolate grade

estimates for all blocks. Other geostatistical techniques such as

uniform conditioning and indicator kriging are also used to quantify the

proportion of economic ore. This is reported according to the

dimensions of the smallest mining unit.

Ore Reserve estimation

Pit optimisation is done using Whittle® pit shells corresponding to the

Ore Reserve gold price and operational costs. For the underground

sulphide orebody (Cuiabá mine and Córrego do Sítio Sulphides) all

mining parameters such as mining method, minimum mining width,

dilution, MCF and the appropriate gold price are considered in

determining the Ore Reserves. The Ore Reserves are scheduled and

designed using Mine2-4D® computer software.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Brazil operations: Serra Grande

Serra Grande

The Serra Grande joint venture (50% attributable to AngloGold

Ashanti) is co-owned with Kinross Gold Corporation. The operation

comprises two underground mines, Mina III and Mina Nova, and a new

open pit. The processing circuit is equipped with grinding, leaching,

filtration, precipitation and smelting facilities.

Serra Grande controls, or has an interest in, approximately 21,068ha in

and around the Crixás mining district in the north-western areas of the

Goiás State in central Brazil. Serra Grande is located 5km from the city

of Crixás.

Geology

The gold deposits are hosted in a sequence of schists, volcanics and

carbonates occurring in a typical greenstone belt structural setting.

The host rocks are of the Pilar de Goiás Group of the Upper Archaean.

Gold mineralisation is associated with massive sulphides and vein

quartz material associated with graphitic, sericitic schists and

dolomites. The ore shoots plunge downwards to the north. The

deposits occur in the Rio Vermelho and Ribeirão das Antes formations

of the Archaean Pilar de Goiás Group, which together account for a

large proportion of the Crixás Greenstone Belt in central Brazil. The

stratigraphy of the belt is dominated by basics and ultra-basics in the

lower sequences with volcano sedimentary units forming the upper

successions.

The gold deposits are hosted in a sequence of schists, volcanics and

carbonates occurring in a typical greenstone belt structural setting. The

host rocks are of the Pilar de Goiás Group of the Upper Archaean. Gold

mineralisation is associated with massive sulphides and vein quartz

material occurs with graphitic and sericitic schists and dolomites. The ore

shoots plunge to the north-west with dips of between 6° and 35°.

The greenstone belt lithologies are surrounded by Archaean tonalitic

gneiss and granodiorite. The metamorphosed sediments are primarily

composed of quartz, chlorite, sericite, graphitic and garnetiferous

schists. The carbonates have been metamorphosed to ferroan

dolomite marble with development of siderite and ankerite veining in

the surrounding wallrock, usually associated with quartz veining. The

basalts are relatively unaltered but do show pronounced stretching

with elongation of pillow structures evident. The ultra-basics form the

western edge of the belt and the basic volcanics and sediments form

the core of the unit. The northern edge of the belt is in contact with a

series of laminated quartzites and quartz sericite schists of the Lower

Proterozoic Araxa Group and a narrow band of graphitic schists and

intermediate to ultra-basic volcanics.

The Crixás greenstone belt comprises a series of Archaean to

Palaeoproterozoic metavulcanics, metasediments and basement

granitoids stacked within a series of north to north-east transported

thrust sheet. Thrusting (D1) was accompanied by significant F1

folding/foliation development and progressive alteration in a brittle-

ductile regime. D1 thrusting developed with irregular thrust ramp

geometry, in part controlled by concealed early basin faults. The main

Crixás orebodies are adjacent to a major north-northwest basement

fault, and an inferred major east-west to south-east flexure in the original

volcano-sedimentary basin. Early D1 alteration fluids were focused from

south to north, adjacent to the north-northwest structural corridor, and

up the main fault ramp/corner, to become dispersed to the east and

north in of foreland thrust fault zones.

Fluid alteration also diminished to the west away from the main fault

flexure. A series of concealed east-west to north-west-south-east

basement block faults may have provided secondary fluid migration, and

development of early anti-formal warps in the thrust sheets; these

structures probably define the quasi-regular spacing of significant

mineralisation within the belt. The D1 thrust stack was gently folded by

non-cylindrical folds. Gold mineralising fluids probably migrated during

this event, with similar south-southwest to north-northeast migration,

and focusing by bedding slip during folding. Gold mineralisation became

minor and dispersed to the north and east along the frontal thrust flat

zone. Concentrations of gold along the base of quartz vein may be due

to the damming of fluids migrating upward along layering.west with dips

of between 6° and 35°. The stratigraphy is overturned and thrust

towards the east.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Colombia exploration: Gramalote

Since the commencement of exploration, AngloGold Ashanti has

staked a total of 10.8 million hectares of exploration claims

countrywide. Of these, 6.5 million hectares have been reviewed and

either relinquished or farmed-out, leaving 4.3 million hectares in

AngloGold Ashanti’s current tenement portfolio. Further rationalisation

of this vast property holding (through both in-house exploration and

farm-outs) continued as a priority in 2007.

The Gramalote project is located 120 road kilometres west-northwest

of Medellin, the capital of the Antioquia department. Site access is by

paved road from Medellin (2.5 hours) and from Bogota (7 hours).

The Gramalote project presently is a joint venture with Vancouver-

based B2Gold Corp. In 2005, Sociedad Kedahda (AngloGold

Ashanti’s subsidiary in Colombia) entered into a joint venture

agreement with the Colombian-based Grupo Nus. As part of the

Joint Venture Agreement, Sociedad Kedahda could earn a 75%

interest in the Gramalote property by completing cash payments,

complying with specific work expenditures and presenting a

feasibility study on or before July 2010. In August 2007, Vancouver-

based B2Gold Corp. purchased the rights to the Grupo Nus

option agreement, including the remaining 25% interest in the

Gramalote property from the Grupo Nus. In November 2007,

AngloGold Ashanti in turn decided to reduce its interest in the

Gramalote property to 49% and offered B2Gold the opportunity to

become the project operator with overall responsibility for taking the

project through feasibility.

Geology

The Gramalote area is underlain by medium to coarse-grained biotite

+\- hornblende tonalite and granodiorite of the Paleocene to

Cretaceous Antioquian batholith. Tonalite from the Gramalote

exploration audit gave zircon ages of 59+1.2ma. Magmatism,

structural events and mineralisation are intimately related.

The location of drill targets is controlled by N70-75E striking steeply SE

dipping transfer zones developed between two sub-regional faults (Rio

Nus, Quebrada Socorro).

On the local prospect scale extensional domains with quartz veinlets

and compressional domains with shear zones have formed.

There are two principal mineralised sectors at Gramalote are Las

Torres and Cerro Gramalote. Both occur in extensional domains

striking N20-30W and dipping 75-80°SW. Gold grades >1g/t often

correlate with increased fracturing (>9 fractures/veinlets per metre) and

the dominant alteration is potassic K-feldspar. Quartz-sericite

overprints and quartz-pyrite-chalcopyrite-molybdenite+gold veinlets

follow subsidiary structures.

Shear zone domains strike N50-60E and dip 75-80SE. Individual

shears zones are often up to 40m apart and N-S veins follow extension

fractures between them. These veins have been targets for small scale

mining at Los Mangos. Alteration in shear zone domains is dominantly

(quartz-) sericite with remnant potassic K-feldspar alteration. Veinlets

are quartz-molybdenite-chalcopyrite-pyrite+sphalerite+gold.

Gramalote

In 2003 AngloGold Ashanti was the first company

to instigate a systematic grassroots exploration

program in Colombia. The Gramalote project is

located 120 road kilometres west-northwest of

Medellin, the capital of the Antioquia department.

Gramalote

In summary, three styles of alteration-mineralisation are distinguished

at Gramalote:

Potassic K-feldspar alteration with associated veinlets and spo-

radically veins;

(Overprinting) quartz-sericite alteration with veins and syn-defor-

mation veinlets; and

Sericite/chlorite-quartz-calcite/illite-smectite alteration on re-

activated fault planes.

Gold grades are attractive, especially in areas characterised by

potassic K-feldspar dominated alteration and quartz-pyrite-

chalcopyrite veinlets. Las Torres and Cerro Gramalote have been

drilled on 100m lines. El Barzal has been partially drill tested and the

La Concha prospect remains undrilled.

Mineral Resource estimation

At Gramalote, some 12,551m of diamond drilling (43 holes) has been

used to support the calculation of a compliant Inferred Mineral

Resource.

The Inferred Mineral Resource estimate tabulated below was

generated using the Indicator Kriging method. All available geological

drill-hole, surface and underground mapping information has been

validated for use in the modelling process.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

The concession area encompasses the entire Kilo greenstone belt,

which has a rich history of gold occurrences. Concession 40 is held in

a Joint Venture between AngloGold Ashanti Kilo (AGAK) and OKIMO,

a governmental body which currently holds a 13.8% non-contributory

share. AGAK is 100% owned by AngloGold Ashanti Ltd.

Most of AngloGold Ashanti’s exploration activities in Concession 40

have focused on the delineation of resources in the vicinity of the

redundant Adidi-Kanga, Nzebi, and Senzere gold mines. These old

mines are collectively centred around the village of Mongbwalu, some

48km north-west of the regional town of Bunia and 320km south-east

of Kampala in neighbouring Uganda.

The improved security situation throughout the remainder of

Concession 40 has allowed for the commencement of a regional

exploration program, including the flying of airborne geophysics over

key parts of the concession.

Geology

The Mongbwalu Project is located within the Kilo Archaean granite-

greenstone belt that extends approximately 850km west-northwest of

Lake Albert. Granitoids are the predominant rock type and they

contain rafts of Kibalian amphibolites and basic talc carbonate schists

that have been intruded by diorite-tonalite-granodiorite assemblages.

The mineralisation is hosted in multiple, shallow dipping mylonite

bodies that average 30m in width. Within the mylonite zones, the gold

is primarily concentrated in boudinaged quartz veins that are

orientated sub-parallel to the mylonite zones and their immediate wall-

rock. The mineral assemblage is simple and contains free gold and

minor (< 2%) sulphides.

The easterly dipping mylonite zones are continuous throughout the

area drilled to date with the most prospective zone located close to the

old Adidi Mine. Two north-south trending faults have offset the

mineralisation and have kept the potential resource area within 150m

to 200m of the surface. Potential remains at depth, both down plunge

on the known mylonite horizons and within subsidiary structures still to

be targeted by drilling.

Concession 40, is located on the Kilo Archaean

granite-greenstone belt that extends approximately

850km west-northwest of Lake Albert.

Democratic Republic of Congo exploration: Mongbwalu

Mongbwalu

AngloGold Ashanti commenced drill testing of the resource potential

of the Mongbwalu area in mid-2005 and by the end of 2006, the

broader Mongbwalu area (Nzebi-Adidi-Kanga-Pluto sectors) had

been diamond drilled on a 200m x 200m grid. The program covered

an area 2.2km by 2.7km centred over the southern part of the

Adidi mine.

From this drilling, distinct zones with potentially economic grades of

gold in quartz-veins were delineated. Infill RC and diamond drilling on

50m x 50m centres was undertaken during 2007 to cover these areas

of maximum potential to host near surface open-pit extractable or

shallow underground extractable mineralisation with the view to

defining an initial inferred resource by the end of 2007. Data obtained

from a total of 87,933m of drilling has been used for resource

modelling and estimation.

The principle Mongbwalu Mylonite horizons and other important

geological units defined by drill-hole logging and interpretation were

modelled using conventional 3D wireframing techniques and Datamine

Software®. To define the Inferred Mineral Resource, resource

envelopes were created using manual wireframing in Datamine® at

cut-off grades of 0.5g/t Au and 3.0 g/t Au. Following geostatistical

evaluation of the drill-hole assay database, gold grades were

interpolated into a 3D block-model incorporating the principle

geological units and resource envelopes using Ordinary Kriging to

define the Inferred Mineral Resource, at a cut-off grade of 0.5 g/t.

Initial scoping level mining metallurgical, geotechnical,

hydrogeological, environmental, socio-political and infrastructural

engineering studies were undertaken in parallel with the drilling to

support the resource estimate in anticipation of the project moving

towards pre-feasibility during 2008.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Ghana operations: Iduapriem

Iduapriem

Iduapriem mine is situated in the western region of Ghana, some 70km

north of the coastal city of Takoradi, and 10km south-west of Tarkwa.

Iduapriem is an open-pit mine. Its processing facilities include a

carbon-in-pulp (CIP) plant.

Geology

The Iduapriem and Teberebie gold mines are located along the

southern end of the Tarkwa basin. The mineralisation is contained in

the Proterozoic Banket Series, conglomerate within the Tarkwaian

System. The outcropping Banket Series in the mine area form

prominent arcuate ridges extending southwards from Tarkwa,

westwards through Iduapriem and northwards towards Teberebie. The

gold is fine-grained, particulate and free milling. Mineralogical studies

indicate that the grain size of native gold particles ranges between

2 microns and 500 microns (0.002 to 0.5mm) and averages 130

microns (0.13mm). Sulphide minerals are present only at trace levels

and are not associated with the gold.

Mineral Resource estimation

All geological interpretations are used to produce a three

dimensional wire frame model of the orebody using Datamine®

software. A prototype block model comprising of 25m x 5m x 6m

blocks is used within the geological model outlines and where

appropriate, selective sub-celling is used for definition on the

geological and mineralisation boundaries. The geostatistical

techniques used for grade interpolation into the blocks include

Multiple Indicator Kriging (MIK), ordinary kriging and inverse distance

squared (ID2) methods.

Ghana operations: Obuasi

Obuasi

The Obuasi mine is located in the Ashanti region of Ghana, some

80km from Kumasi. Historically, Obuasi has been an underground

mine, although there was large-scale open-pit mining between 1990

and 2000. The mine has two active treatment plants: the sulphide

treatment plant to process underground ore and the tailings treatment

plant to handle tailings reclamation operations.

Geology

The gold deposits at Obuasi are part of a prominent gold belt of

Proterozoic (Birimian) volcano-sedimentary and igneous formations.

These deposits extend for a distance of approximately 300km, in a

north-east/south-west trend, in south-western Ghana. Obuasi

mineralisation is shear-zone-related and there are three main structural

trends hosting gold mineralisation: the Obuasi trend, the Gyabunsu

trend and the Binsere trend.

Two main ore types are mined:

quartz veins which consist mainly of quartz with free gold in

association with lesser amounts of various metal sulphides

containing iron, zinc, lead and copper. The gold particles are

generally fine-grained and are occasionally visible to the naked eye.

This ore type is generally non-refractory; and

sulphide ore which is characterised by the inclusion of gold in the

crystal structure of a sulphide material. The gold in these ores is

fine-grained and often locked in arsenopyrite. Higher gold grades

tend to be associated with finer grained arsenopyrite crystals. Other

prominent minerals include quartz, chlorite and sericite. Sulphide

ore is generally refractory.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Mineral Resource estimates are derived from interpretations of

information about the location, shape, continuity and grade of the

individual ore bodies. The open-pit Mineral Resource was estimated

using three dimensional computer block models constructed using

the Datamine

software. Geological interpretation was based on

trench and reverse circulation and or diamond drilling data. A

prototype block model of 30m x 30m x 10m was used within the

Geological Model envelope. Ordinary kriging was used as the primary

estimation methodology.

97% of the underground Mineral Resource was estimated using block

models within the delineated ore zones. A prototype block model of

20m x 5m x 15m representing the Minimum Mining Unit was used and

estimates are based on ordinary kriging. The remaining 3% of the

resource are global estimates.

Surface stockpiles volumes are based on a surveyed figures and

grades based on historical sampling. Tailings are part of the Mineral

Resource with tons and grades based on a combinations of 3D

models of some dams and historical metallurgical discharge data.

Ore Reserve estimation

The three dimensional Mineral Resource models are used as the basis

for the Ore Reserves. An ore envelope is developed using the Mineral

Resource block model, geological information and the relevant cut-off

grade, which is then used for mine design. Datamine® software called

Mineral Resource Optimizer is used to generate the ore envelope. An

appropriate mining layout is designed that incorporates mining

extraction losses, dilution factors and MCF.

Resource definition drilling consists of Air Core (AC), Reverse

Circulation (RC) and Diamond Drilling (DD) boreholes. All available

geological drill-hole information is validated for usage in the models

and the local geology of the orebody is used to classify the drill-hole

information into appropriate geostatistical domains. Detailed statistical

analyses are conducted on each of these domains and this allows for

the identification of high grade outliers. If these values are anomalous

to the general population characteristics then they are cut back to the

appropriate upper limit of the population.

The Mineral Resources are estimated using three dimensional

computer block models constructed in Datamine® software.

Geological interpretation is based on Geological borehole data. A

prototype block model ranging from 10m x 10m x 2.5m to 50m x 25m

x 6m block sizes depending on the shape of the orebody is used

within the Geological model outlines. Ordinary and indicator kriging are

used to estimate gold grades and a limiting pit shell at $650/oz is used

to quantify the total Mineral Resources.

assigned on a pit by pit basis reflecting the current existing cost

structure of the operation. The relevant dilution and ore loss

factors are applied and the optimisation is done in Earthworks®

NPV Scheduler software. The relevant metallurgical recoveries,

geotechnical parameters, cut-off grades and economics are

applied to generate the final Ore Reserve.

Guinea operations: Siguiri

Siguiri

Société Ashanti Goldfields (SAG) de Guinée

Siguiri gold mine is situated in the Siguiri district in the north-east of the

Republic of Guinea, West Africa, about 850km from the capital city of

Conakry. The SAG concession consists of four blocks totalling

1,494.58km

. All ore and waste is mined by a mining contractor in a

conventional open-pit mining operation. Processing is done via a

CIP plant.

Geology

This concession is dominated by Proterozoic Birimian rocks which

consist of turbidite facies sedimentary sequences. There are two main

types of gold deposits that occur in the Siguiri basin: laterite

mineralisation (CAP) and in situ quartz-vein-related mineralisation. The

laterite mineralisation occurs as aprons of colluvial or as palaeo-channels

of alluvial lateritic gravel adjacent to and immediately above the in situ

vein-related mineralisation. The vein-related mineralisation is hosted in

meta-sediments with the better mineralisation associated with vein

stockworks, that occur preferentially in the coarser, brittle siltstones and

sandstones. The mineralised rocks have been deeply weathered to

below 100m in places to form saprolite (SAP) mineralisation. The

practice at Siguiri has been to blend the CAP and SAP ore types and to

process these using the heap-leach method. With the percentage of

available CAP ore decreasing, however, a CIP plant was brought on

stream during 2005 to treat predominantly SAP ore.

Mineral Resource estimation

The Mineral Resource is taken as the material that falls within the

$700/oz economic shell optimised for each individual deposit except

for Morila and Alamoutala (Yatela). The pits at these operations are

reaching the end of their lives and the Mineral Resource is quoted

within the life of mine design. A three dimensional surface is generated

to create the outline of the geological model. This model is then used

as a prototype model to estimate grades. Block sizes between 25m x

25m x 10m and 30m x 30m x 10m (X Y Z) and where appropriate

selective sub-celling is used for definition on the geological and

mineralisation boundaries. The dimensions of these sub cells are

12.5m x 12.5m x 3.33m and 10m x 10m x 5m. All the deposits have

kriged block models and where appropriate a geostatistical

technique called Uniform Conditioning is used to estimate the

proportion of economic ore that occur above the Mineral Resource

cut-off and this is reported according to the dimensions of the

practical mining unit.

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Ore Reserve estimation

The Mineral Resource models are used as the basis for the Ore

Reserves. Pit optimisation is done using Whittle® software. The typical

Whittle approach for a mill-constrained operation is followed.

Optimisations are run on Measured and Indicated Mineral Resources

and Measured, Indicated and Inferred Mineral Resources. All

appropriate costs, metallurgical recovery factors and geotechnical

parameters are applied to generate the final Ore Reserves.

Mali operations: Morila

This mine is situated some 280km by road southeast of Bamako, the

capital city of Mali, which is 600km south-east of Sadiola mine. Mining

is from a single open-pit operation, utilising conventional truck and

shovel methods.

Geology

The Morila orebody is located predominantly in metasediments within

a broad NNW trending corridor of shearing. This shear zone has both

near vertical and flat lying components. It is interpreted as being a

second order shear off the main Banafin shear approximately 25km to

the east. The Doubalakoro granite pluton bounds the sediments to the

west and the Massigui granite to the east. The deposit occurs within a

sequence of metamorphosed Birimian meta-sediments (amphibolite

facies). Gold mineralisation is associated with silica feldspar alteration

and the sulphide minerals arsenopyrite, pyrrhotite, and pyrite (with

minor chalocopyrite).

AngloGold Ashanti Supplementary Information: Mineral Resources and Ore Reserves 2007

Mali operations: Sadiola

Sadiola

Sadiola is situated in the north-west of Mali, 77km to the south of the

regional capital of Kayes. Mining takes place in an open pit at Sadiola.

Ore is treated in a 435,000-tonne-per-month gold plant.

Geology

The Sadiola deposit is located within the Malian portion of the

Keniéba- Kedougou window, a major early proterozoic – Birimian

outlier along the NE margin of the Kenema – Man shield. The deposit

is confined in the north of the window and the mineralised zone occurs

along the Sadiola Fracture Zone (SFZ), over a drilled strike length of

approximately 2,500m and remains open to the north and south. The

observed alteration assemblages in the primary mineralisation point to

a mesothermal origin for the gold deposit at Sadiola. The specific

rocks that host the mineralisation are marbles and greywackes which

have been intensely weathered to a maximum depth of 200m. A series

of north-south trending faults occur that feed the Sadiola mineralisation.

As a result of an east-west regional compression event, deformation

occurs along a north-south striking marble-greywacke contact,

increasing the porosity of this zone. North-east striking structures, which

intersect the north-south contact, have introduced mineralisation, mainly

within the marble where the porosity was greatest.

The Sadiola Hill deposit generally consists of two zones, an upper

oxidised cap and an underlying sulphide zone. From 1996 until 2002,

shallow saprolite oxide ore was the primary ore source. Since 2002,

the deeper saprolitic sulphide ore has been mined, progressively

replacing the depleted oxide reserves.

Mali operations: Yatela

Yatela

Yatela is situated some 25km north of Sadiola and approximately

50km south-southwest of Kayes. Mining takes place in an open pit.

Geology

Yatela mineralisation occurs as a keel-shaped body in Birimian

metacarbonates. The ‘keel’ is centred on a fault which was the feeder

for the original mesothermal mineralisation, with an associated weakly

mineralised diorite intrusion. This primary mineralisation was

concentrated to economic grades through dissolution of carbonate-

rich rocks by supergene processes. Gold is disseminated in the

unconsolidated ferruginous, sandy, locally clayed layer that lines the

bottom of a deep trough (max 220m deep) with steep margins. The

ore dips almost vertically on the west limb and more gently towards the

west on the east limb, with tight closure to the south.

Mineral Resource estimation

Mineral Resource estimation is performed using Datamine® Software.

Block dimensions of 25m x 25m x 5m (X Y Z) and 25m x 125m x 5m

are used as the prototype model. Grade interpolation is done into

these blocks using Ordinary and Indicator Kriging methods. A

geostatistical technique called Uniform Conditioning is then used to

estimate the proportion of economic ore that occur above the Mineral

Resource cut-off and this is reported according to the smallest mining

unit (SMU).

Namibia operations: Navachab

Navachab

Navachab gold mine is located 10km south-west of Karibib and

170km north-west of Windhoek, the capital of Namibia. Navachab

mine is an open-pit mine. Its processing plant, with a production

capacity of 110,000 tonnes per month, includes mills, CIP and electro-

winning facilities.

Geology

The Navachab gold deposit is located in the Pan-African Damara

Orogen and is hosted by Damaran greenschist-amphibolite facies,

calc-silicates, marbles and volcano-clastics. The rocks have been

intruded by granites, pegmatites and (quartz-porphyry dykes) aplite

and have also been deformed into a series of alternating dome and

basin structures. The mineralised zone forms a sheet-like body which

plunges at an angle of approximately 20° to the north-west. The

mineralisation is predominantly hosted in a sheeted vein set (±60%) and

a replacement skarn body (±40%). The mineralisation in the Main Pit is

hosted by a NE-SW striking metamorphosed sequence of greenschist-

amphibolite facies, calc-silicates, marbles and volcanoclastics rocks

that dip at 70° to the west. The gold is very fine-grained and associated

with pyrrhotite and minor amounts of pyrite, chalcopyrite, maldonite

and bismuthinite. An estimated 90% of the gold occurs as free gold and

the remainder is present in minerals such as maldonite (Au2Bi).

Approximately 80% of the gold is free milling. Silver is also present and

the gold to silver ratio is approximately 15 to 1.

Geita is the largest of AngloGold Ashanti’s

seven open-pit mines in Africa. Prior to

April 2004, Geita was managed under the

joint venture agreement between Ashanti

and AngloGold. After the merger of the two

companies, Geita is now a wholly owned

subsidiary.

As with any estimation techniques the results are very dependent upon

the data quality and availability. The geological model is a critical input

to the Mineral Resource estimation process. The orebody boundaries

for the individual deposits are defined from the detailed logging of all

geological boreholes and after validation this information is used to

create a three dimensional model. This model is subsequently

populated with an appropriately dimensioned block model. The size of

this block model is determined by analysing different block sizes in

relation to the variance of the blocks. A block size which gives an

optimal variance is then chosen. (40m x 40m x 5m) ordinary kriging is

used to interpolate values into the blocks. A geostatistical technique

called Uniform Conditioning is then used to estimate the proportion of

economic ore that occur above the Mineral Resource cut-off and this

is reported according to the selective mining unit (SMU).

Ore Reserve estimation

The Mineral Resource models as produced by the geology

department are used as the basis for the Ore Reserve. Appropriate

mining dilution is used as a modifying factor in the Ore Reserve

conversion process. Appropriate reserve cut-off grades are applied

and optimised pit shells are generated taking into cognisance the

economic parameters. The final pits are then designed taking into

consideration the optimised pit shell and recommended slope

geometry.

Bulyanhulu, Tulawaka and North Mara. This geological terrain is

considered to be one of the most productive Archaean Greenstone

Belts in East Africa. Mining at Geita is undertaken by standard open-

pit mining methods.

Geology

The Geita Greenstone trend is a component of the Sukumaland

Greenstone Belt; it strikes east-west, is 60km long and up to 15km

wide. The terrain is made up of upper to mid-Nyanzian greenstone

facies rocks, mainly clastic sediments, intermediate to felsic

volcaniclastics and Banded Iron Formation that forms a sedimentary

sequence up to 1,000m thick. In the mine lease area, north west

trending deformation corridors separate the Geita Greenstone trend

into three distinct sub-terrains, which have been named Nyamulilima in

the west, Geita in the central part and Kukuluma to the north-east.

Late dextral faults have utilised these corridors, reactivating the pre-

existing fault systems. Gold mineralisation and hydrothermal alteration

of the host lithologies, on all scales, is associated with late stage

ductile to brittle-ductile deformation.

In March 1999 AngloGold Ashanti acquired the

Pikes Peak Mining Company, and interests in the

Cripple Creek & Victor Gold Mining Company

(CC&V) and the Jerritt Canyon joint ventures. The

stake in the Jerritt Canyon joint venture was sold to

Queenstake in mid-2003. AngloGold Ashanti

(Colorado) Corporation holds a 67% interest in

CC&V with a 100% interest in gold produced until

loans extended to the joint venture are repaid.

Mineral Resource estimation

A single unified Mineral Resource model has been developed for the

entire district. The unified model encompasses all known deposits and

drilling within the CC&V property. Smaller sub-models are maintained

for Altman and Wild Horse to accommodate the vertical shift in the

mining benches. The estimation method is MIK and the primary

variable estimated is the recoverable gold (not contained gold). An

estimated iron and oxide model is utilised to interpolate block specific

coefficients for input into the metallurgical recovery function.

The method for calculating nominal shake leach values (SLV) is a

robust regression technique using geologically logged categorical

variables. Modelling software is MineSight® and updated drill hole

information is used throughout. The drill-hole database is thoroughly

reviewed before each Mineral Resource estimation and the estimation

domains are based primarily on lithology for each deposit.

Inferred Mineral Resource in business plan

Inferred Mineral Resource is not used in the pit optimisation.

Ore Reserve estimation

The Ore Reserve pit designs were based on Lerch-Grossman (LG)

optimisations of the geological model. The LG algorithm applies

economic values to individual blocks and then generates a pit shell

based on geotechnical constraints. Successive nested shells are

generated until the economic limits of the pit are established. These

shells are then used as a template for final mine design. Pit slope

designs for all deposits were based on geotechnical studies and fell

into two categories of overall angles (60° and 45°). All deposits were

designed using a 10.7m (35 feet) bench height.

United States operations: Cripple Creek and Victor (CC&V)

CC&V is located south-west of Colorado Springs in the state of

Colorado in the United States. Large-scale surface mining began in

1991 and grew with the start of production at the CC&V Cresson

Project in 1994. Today, CC&V is a low-grade, open-pit operation. The

ore is treated using a valley-type, heap-leach process with activated

carbon used to recover the gold. The resulting doré buttons are

shipped to a refinery for final processing.

Geology

The dominant geological feature of the District is an intensely-

altered, alkaline Tertiary-aged, diatreme-intrusive complex hosted in

Precambrian rocks located between the towns of Cripple Creek and

Victor. The Precambrian rocks consist of biotite gneiss,

granodiorite, quartz monzonite and granite. The diatreme intrusive

complex is 6.4km long, 3.2km wide and consists of diatremal

breccia that has been intruded by stocks, dykes and discordant

breccias. Diatremal breccia lithologies include breccias composed

exclusively of volcanic, Precambrian or sedimentary material to any

combination of the three. Early intrusions are predominantly within

the alkaline phonolite-phonotephrite petrographic series and were

followed by later lamprophyres. All rocks have undergone a

complex history of structural deformation and hydrothermal activity.

Gold mineralisation, dated between 27.8 Ma and 26.6 Ma is hosted

in all rock types as veins and disseminated and/or structurally-

controlled orebodies.

The majority of the complex in-filled with the eruptive phase Cripple

Creek Breccia host rock. This complex was subsequently intruded by

a series of Tertiary-aged intrusive dykes and sills that included syenites,

phonolites, phonotephrites and lamprophyres. These intrusives occupy

all of the dominant district structural orientations as do laccoliths and

cryptodomes. District structures are generally near vertical and strike

north-northwest to north-east. These structures are commonly intruded

by phonolite dykes which appear to have also acted as primary

conduits for the late-stage, gold mineralising solutions. Higher grade

pods of mineralisation occur at structural intersections and/or as

sheeted vein zones along zones of strike deflection. High-grade gold

mineralisation is associated with K-feldspar + pyrite +/- carbonate

alteration and occurs adjacent to the major structural and intrusive dyke

zones. The broader zones of disseminated mineralisation occur

primarily as micro-fracture halos around the stronger alteration zones in

the more permeable Cripple Creek Breccia wall rocks.

The average depth of oxidation is 120m and is also developed along

major structural zones to even greater depths. Individual orebodies

can be tabular, pipe-like, irregular or massive. Individual gold particles

are generally less than 20 microns in size and occur as native gold with

pyrite or native gold after gold-silver tellurides. Gold occurs within

hydrous iron and manganese oxides and as gold-silver tellurides. Silver

is present but is economically unimportant. Gold mineralisation can be

encapsulated by iron and manganese oxides, pyrite, K-feldspar

alteration and quartz.
