Thunder Bay, Ontario--(Newsfile Corp. - April 2, 2026) - Thunder Gold Corp. (TSXV: TGOL) (FSE: Z25) (OTCQB: TGOLF) ("Thunder Gold" or the "Company") is pleased to announce the addition of Donovan Bailey, O.C., O.Ont., 5 X World & Olympic Champion, entrepreneur and philanthropist, to the Company's Board of Directors.

Donovan Bailey O.C.,O.Ont., became the greatest sprinter on earth, winning double gold medals at the 1996 Atlanta Olympics breaking the world record in the 100-metre in a time of 9.84 seconds, the other one for the Men's 4 x 100-metre relay. Mr. Bailey was the first man in history to be Olympic champion, World champion and World record holder. The Men's 100-metre race is arguably the most watched event at the Summer Olympic games. Whilst winning gold medals and setting a world record gave Donovan instant fame and opened doors and connections for him around the world it's his business acumen and business savvy that has maintained his public appeal and close ties to the global business community. Mr. Bailey is very protective and selective on how and with whom he utilizes his connections, recognizing the value he brings to support business ventures.

Donovan explained his involvement in Thunder Gold saying, "I was introduced to Thunder Gold by their CFO who I have known for many years. Not only was it an easy story to follow but the upside potential is extremely attractive. I know that I can help to raise the profile of the Company and likely get meaningful eyes on it. This could be one of Canada's biggest discoveries and I want to be part of building this exciting Ontario gold story."

Thunder Gold, a publicly traded gold exploration company, is focused on their Tower Mountain project, located just 40 km. west of Thunder Bay, Ontario. It is reached directly off the Trans-Canada highway, year-round. Both national rail lines run next to the property with a rail siding by the property gate. Hydro crosses one end of the property. The proximity of Thunder Bay means workers can be home with their families each night. There is no need to build roads or a camp at the property.

Wes Hanson, President and CEO, states, "We are very pleased to have Donovan Bailey join our Board of Directors. He has a solid business mind and maintains the same discipline and focus that he drew on to succeed in his sport. His enthusiasm to support Thunder Gold is very encouraging. We look forward to working with Donovan as we evolve Thunder Gold's Tower Mountain toward a Tier 1 gold property."

On January 26, 2026, the Company announced a mineral resource estimate for Tower Mountain as summarized in Table 1. The estimate was prepared by Micon International Limited ("MICON"), Toronto, Ontario, Canada, an independent engineering firm specializing in mineral resource and reserve estimation for a global client pool.

Table 1. Tower Mountain Mineral Resource Estimate - January 19, 2026

Notes:

1. The effective date of this Mineral Resource Estimate ("MRE") is January 19, 2026.
2. William Lewis, P.Geo., Charley Murahwi, P.Geo., FAusIMM, and Tudorel Ciuculescu, P.Geo. from Micon International Limited are the Qualified Persons (QPs) responsible for this MRE.
3. The MRE has been classified in the Indicated and Inferred categories. At this time, there are no Measured resources at the Tower Mountain Project.
4. The calculated gold cut-off grade is 0.19 g/t Au.
5. An average specific gravity (SG) value of 2.77 g/cm3 was used.
6. The MRE used economic assumptions for open pit mining. The following economic parameters were used for generating the cut-off grade: a gold price of US$3,000/oz, 80% recovery, open pit mining cost of US$3.0/t, processing costs of US$8.0/t, general and administration cost of US$3.5/t, transportation cost of US$2.5/oz of gold, and a royalty of 3%.
7. The open pit used slope angles of 30° in overburden and 50° in fresh rock.
8. The block model is orthogonal and has a parent block size of 5 m x 5 m x 5 m, with minimum sub-block size of 2.5 m x 2.5 m x 2.5 m.
9. The open pit optimization used a re-blocked size of 10 m x 10 m x 10 m.
10. The mineral resources described above have been prepared in accordance with the current Canadian Institute of Mining, Metallurgy and Petroleum Standards and Practices.
11. Numbers have been rounded to the nearest million tonnes and nearest thousand ounces. Differences may occur in totals due to rounding.
12. Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. The quantity and grade of reported Inferred Mineral Resources are uncertain in nature and there has been insufficient exploration; however, it is reasonably expected that a significant portion of Inferred Mineral Resources could be upgraded into Indicated Mineral Resources with further exploration.
13. Micon QPs have not identified any legal, political, environmental, or other relevant factors that could materially affect the potential development of the mineral resources and of the estimate.

The Company also notes that the Board has approved the grant of 10,150,000 options at a strike price of $0.15 for an 18-month term to Officers, Directors and Consultants of the Company.

About the Tower Mountain Gold Property

The 100%-owned Tower Mountain Gold Property is located adjacent to the Trans-Canada highway, approximately 40-km west of Thunder Bay, Ontario. The 2,100-hectare property surrounds the largest, exposed, intrusive complex in the eastern Shebandowan Greenstone Belt where most known gold occurrences have been described as occurring either within, or proximal to, intrusive rocks. Gold at Tower Mountain is localized within extremely altered rocks parallel to the western contact of the intrusive center. Drilling has established anomalous gold extending out from the intrusive contact for over 500 metres along a 1,500-metre strike length, to depths of over 500 metres from surface. The remaining 75% of the perimeter surrounding the intrusion shows identical geology, alteration, and geophysical response, offering a compelling exploration opportunity.
