Cu-Ni-Pt-Pd-Au Discovered at Surface in

Footwall Rocks Behind Kirkwood Mine


TORONTO: August 3, 2005 - FNX Mining Company Inc. (FNX-TSX/AMEX) reports the discovery of a new massive sulphide surface showing containing high-grade, copper-nickel-platinum-palladium-gold mineralization (e.g. channel sample CH4 - 18.9 ft grading 2.3% Cu, 0.7% Ni and 7.9 g/t Pt-Pd-Au) on its 75%-owned Sudbury Joint Venture Kirkwood Property located in Sudbury, Ontario (Figure 1). Limited drilling of the discovery to date, which has been named the Segway Discovery, intersected similar high-grade mineralization at shallow depths (e.g. FNX8001 - 25.6 ft grading 5.4% Cu, 0.8% Ni and 16.7 g/t Pt-Pd-Au). The strike length and possible size of the discovery near surface appear limited at this time, but additional drilling at depth along with geological and geophysical surveys is required to determine the significance of this new discovery.


The Kirkwood Mine Property (Figure 2) occurs within the very prolific South Range of the Sudbury Basin. This  south-east part of the South Range hosts the Frood Mine, the Stobie Mine, the Little Stobie Mine, the Kirkwood Mine, the Garson Mine, the Falconbridge Mine and the East Mine. Inco Limited’s currently operating Garson Mine is located contiguous to and midway between the Kirkwood and the Falconbridge Mine Properties.


A geological mapping and prospecting program was initiated on the Kirkwood Property earlier this summer as a lead in or segue to exploring the recently acquired Falconbridge Mine Property. The Kirkwood exploration program was designed to augment the FNX geologists' local knowledge of the ore controls in this part of the Sudbury Basin and to assist them in planning and carrying out the 2005 Exploration Program on the recently acquired Falconbridge Mine property, which is located along strike and approximately two miles to the northeast of the Kirkwood Property.


The initial work on the Kirkwood Property discovered a previously undocumented two inch wide vein of massive sulphides containing high-grade Cu-Ni-Pt-Pd-Au values, approximately 2,000 ft behind the Kirkwood Mine (Figure 3).  Subsequent work, including geological mapping, airborne geophysical follow-up, beepmat prospecting, surface stripping and channel sampling trenching revealed the two inch vein to be connected to a 53 ft long lens of massive sulphide, dominated by pyrrhotite with minor chalcopyrite, within mineralized Sudbury Breccia and quartz diorite. The highest precious metal values are within the massive sulphide lens and are dominated by palladium with significant platinum and gold.  


Trenching, mapping and channel sampling results are presented in Figure 4.

The three drill holes that intersected the sulphide lens have tested the mineralization to 250 ft beneath the trench (Figure 5 and Table 1).  A drillhole 100 ft to the west and two drillholes 100 ft to the east intersected the favourable breccia horizon, but did not intersect massive sulphides or the associated quartz diorite (Figure 6). Though the plunge of the mineralization remains open at depth its strike length appears to be limited near surface. Further work including drilling along strike and at depth will continue later this summer.


The formerly producing Kirkwood Property is located in Garson Township some 11 kms northeast of Sudbury (Figure 1).  Copper and nickel sulphide mineralization was discovered in 1892 and, following several small mining ventures in the early 1900s, the Property was acquired and put into production by Inco Limited using a 2,150 ft vertical shaft. Historical production from Kirkwood totalled approximately 2,695,000 tons grading 1.00% Cu, 0.90% Ni and 2.3g/t TPM


The discovery of significant Cu-Ni-Pt-Pd-Au mineralization some 2,000 ft into the footwall behind the Kirkwood Mine not only demonstrates the potential of the footwall rocks in this part of the Sudbury Basin but also at the nearby Falconbridge Property. The footwall rocks of the Kirkwood and Falconbridge Mine properties are considered to be relatively unexplored and to have significant potential to host Sudbury Basin type footwall deposits. In addition, the Falconbridge Mine property, (historic production of 42,000,000 tons grading 1.5% Ni, 0.9% Cu and 1 g/t TPMs) which was recently acquired in the Aurora Platinum transaction, is mostly covered by widespread glacial outwash sand which may have hindered surface exploration and prospecting along the five miles of highly favourable Sudbury Breccia and footwall rocks on the Property.



Sudbury Joint Venture – General  

The Sudbury Joint Venture is owned 75% by FNX (exploration operator) and 25% by Dynatec Corporation (mining operator). The Sudbury Joint Venture properties (McCreedy West, Levack, Victoria, Podolsky (formerly Norman) and Kirkwood) are all former copper, nickel, platinum, palladium, gold producers located in the Sudbury District of northeastern Ontario and are covered by previously announced agreements between FNX and Dynatec (see February 3, 2002 FNX and Dynatec press release). For a detailed description of the properties and previous work, please go to the FNX website “www.fnxmining.com” and refer to FNX’s Annual Information Form dated March 31, 2005.


The Aurora Platinum Sudbury properties cover approximately 30,102 acres, including the Falconbridge Property located in the southeast corner of the Sudbury Basin and the Foy-Bowell Property situated on the North Range of the Basin.  The Falconbridge Property hosts approximately five miles of favourable Sudbury Breccia footwall, while the Foy-Bowell Property contains approximately nine miles of offset dyke target along the Foy Offset structure plus a large area of prospective footwall potential.


James M. Patterson, Ph.D., P.Geo., Executive Consultant, is the designated Qualified Person and is responsible for the verification and quality assurance of the Sudbury Joint Venture’s exploration data and analytical results. Anthony P. Makuch, M. Eng., P. Eng., M.B.A., and Dynatec’s Vice President, Sudbury Joint Venture Mining Operations, oversees mining activities on behalf of the Sudbury Joint Venture. Samples of half core are prepared at SGS Lakefield Laboratories in Garson and shipped to ALS Chemex in Vancouver for assay. Please see the July 16, 2003 FNX news release and the March 31, 2005 Annual Information Form for a description of sample preparation and assay procedures for the Sudbury Joint Venture.
