Tudor Gold Commences 10,000-Metre Drill Program Targeting Higher-Grade Zones at Treaty Creek

• Two diamond drills operating at Treaty Creek with a minimum of 10,000 metres planned across CBS and Perfectstorm zones targeting higher-grade gold, copper and silver mineralisation along the Sulphurets Thrust Fault.
• Phase 1 comprises 2,000 metres at CBS Zone, following up on previous intercepts of 0.78 grammes per tonne (g/t) gold and 2.34 g/t silver over 155 metres, including 1.24 g/t gold and 4.35 g/t silver over 53 metres.
• Structural reinterpretation informed by University of British Columbia research targets a potential mineralisation corridor between the CBS Zone and the genetically linked Goldstorm Deposit.
• Phase 2 comprises 8,000 metres at Perfectstorm Zone, targeting both porphyry-style mineralisation similar to Goldstorm and epithermal-style gold and silver mineralisation in outlying areas.
• Drilling is expected to continue through late September to early October 2026.

Company Overview

Tudor Gold Corp. (TSX-V: TUD | OTC: TDRRF | FRA: H56.f) is a precious and base metals exploration and development company with claims in British Columbia's Golden Triangle, an area hosting producing and past-producing mines and several large deposits approaching potential development. The 17,913-hectare Treaty Creek Project, in which Tudor Gold holds an 80% interest, borders Seabridge Gold's KSM property to the southwest and Newmont Corporation's Brucejack Mine property to the southeast.

Two-Phase Programme Targets CBS & Perfectstorm Zones 

Tudor Gold commenced its 2026 exploration program at the Treaty Creek Project in British Columbia's Golden Triangle with 2 diamond drills operating and a minimum of 10,000 metres of drilling planned. The program targets higher-grade mineralisation identified in 2 of 3 known gold zones along the Sulphurets Thrust Fault near the Goldstorm Deposit.

The Treaty Creek Project hosts the Goldstorm Deposit, which contains Indicated Mineral Resources of 24.9 million ounces of gold, 148.7 million ounces of silver and 3.048 billion pounds of copper, grading 0.85 grams per tonne (g/t) gold, 5.07 g/t silver and 0.15% copper across 912.3 million tonnes. Inferred Mineral Resources comprise 2.6 million ounces of gold, 7.2 million ounces of silver and 67.9 million pounds of copper, grading 3.64 g/t gold, 10.22 g/t silver and 0.14% copper across 21.8 million tonnes, as disclosed in the November 30, 2025, NI 43-101 Technical Report.

The exploration program is structured in two phases targeting zones at different elevations and geological settings along the Sulphurets Thrust Fault corridor.

CBS Zone Drilling Tests Structural Link to Goldstorm

Phase 1 of the 2026 program commenced at the CBS Zone with 2,000 metres of drilling planned. The CBS Zone sits at a lower elevation than other identified zones at Treaty Creek, enabling drilling both earlier and later in the exploration season than higher-elevation targets.

The phase targets previous results, including intercepts of 0.78 g/t gold and 2.34 g/t silver over 155 metres, with a higher-grade interval of 1.24 g/t gold and 4.35 g/t silver over 53 metres. Tudor Gold compiled results from previous field exploration programs alongside research completed by the Mineral Deposit Research Unit (MDRU) at the University of British Columbia to produce a structural reinterpretation of the CBS Zone.

This reinterpretation targets potential mineralisation extending towards the Goldstorm Deposit. The CBS Zone and Goldstorm Deposit are thought to be genetically linked, suggesting a potential mineralised corridor between the two areas along the Sulphurets Thrust Fault structure.

Perfectstorm Zone Programme Follows Up on Geophysics & High-Grade Intercepts

Phase 2 focuses on the Perfectstorm Zone with 8,000 metres of drilling planned. The programme follows up on geophysics completed in 2022 and higher-grade drill intercepts from the 2023 program.

In the 2023 drill program, intercepts included 1.23 g/t gold and 3.43 g/t silver over 102.15 metres, including a higher-grade interval of 42.5 metres grading 1.80 g/t gold and 5.76 g/t silver. The Perfectstorm Zone programme targets two distinct mineralisation styles identified in previous drilling.

The Perfectstorm Zone programme targets both porphyry-style gold, silver and copper mineralisation hosted within potassic altered diorites similar to Goldstorm, as well as outlying gold and silver-rich epithermal-style mineralisation in different geological settings. The dual-target approach reflects the geological complexity of the Perfectstorm Zone and aims to test both porphyry and epithermal models in a single phase of drilling.

Next Steps

The 2 diamond drills are expected to continue drilling through late September to early October 2026. Tudor Gold will release assay results as they are received and compiled, with the exploration program focused on following up higher-grade intercepts and testing structural interpretations developed from previous work at both the CBS and Perfectstorm zones.

The Goldstorm Deposit remains open in all directions. Tudor Gold has filed a permit application for approval to construct an underground ramp to access and drill the high-grade SC-1 Zone. A Preliminary Economic Assessment (PEA) on placing the Goldstorm Deposit into production as an underground mine is currently underway.
