Sitka Drills 159.2 Metres of 1.14 g/t Gold, Including 7.3 Metres of 8.89 g/t Gold, Within 256.9 Metres of 0.84 g/t Gold, Intercepts 13.9 Metres of 0.383% WO3 (Tungsten Trioxide) and Continues to Expand the Rhosgobel Deposit Along Strike and at Depth at It

Sitka Gold Corp. (SIG) has released new assay results from step-out and infill drilling at the Rhosgobel deposit within its RC Gold Project in Yukon. The company clarified that the release serves as a drilling update rather than a resource estimate or economic study.

Key reported intercepts include: - DDRCRG-26-071: 256.9 m @ 0.84 g/t Au, including 159.2 m @ 1.14 g/t Au and 7.3 m @ 8.89 g/t Au. - DDRCRG-26-059: 43.5 m @ 1.29 g/t Au within 217.9 m @ 0.52 g/t Au. - DDRCRG-26-061: 82.0 m @ 0.75 g/t Au, including 10.4 m @ 1.03 g/t Au, within 322.0 m @ 0.50 g/t Au. - DDRCRG-26-067: 102.2 m @ 0.57 g/t Au, including 22.1 m @ 1.03 g/t Au. - DDRCRG-26-063: 13.9 m @ 0.383% WO3 tungsten trioxide.

The company stated that gold and tungsten mineralization has been extended approximately 350 m east of the easternmost 2025 drilling, with assays pending for holes located a further 60 m east. Rhosgobel is now traced over about 1.6 km of strike and remains open along strike and at depth. Approximately 45,000 m of a planned 60,000 m 2026 program has been drilled across 101 holes, with seven rigs currently active.

Sitka Gold Corp. (SIG) is an explorer and developer with a 5.12 moz indicated plus inferred resource and a market capitalization of roughly C$447 million. The company is viewed as an advanced, well-funded Yukon gold story, with the market pricing a growing multi-million-ounce resource supported by a 60,000 m drill program rather than a blind grassroots discovery.

The latest release expands the Rhosgobel deposit along strike and at depth. The headline hole was broad and above resource grade, though it did not represent a major grade or tonnage transformation. Step-out results were consistent with the known low-grade bulk system.

The prior Rhosgobel anchor remains the 235.9 m @ 1.11 g/t Au, about 262 gram-metres, from September 2025. The new best Rhosgobel interval, DDRCRG-26-071, is about 216 gram-metres on its outer interval and has a lower average grade. The new step-out holes are lower grade than the resource average.

The stock has not re-rated aggressively into this release. It sits near C$1.03, below its August high of C$1.13 and well below its 52-week high of C$1.29. Because the company is already valued for a large resource and continuous exploration success, these results likely confirm the model without re-pricing the stock. Infill and resource-adjacent step-out holes at or above resource grade are routine positive confirmations even when gram-metres are lower than earlier headline holes.

Sitka Gold Corp. is a Yukon-focused gold explorer and developer with a 100% owned flagship asset, the RC Gold Project. Spanning 447 square kilometres in the Tombstone Gold Belt, the property is located approximately 100 km east of Dawson City and is road-accessible. The project contains the Blackjack, Eiger, and Rhosgobel deposits, which hold reported mineral resources of 1.29 million ounces indicated and 3.83 million ounces inferred gold. The Rhosgobel deposit alone accounts for an inferred resource of 2.25 million ounces at 0.70 g/t Au, with secondary tungsten potential also identified at the site.

The company completed the acquisition of Clear Creek in 2025, consolidating its ground around Rhosgobel. Meanwhile, it is spinning out other assets, including Alpha Gold in Nevada and Burro Creek in Arizona. Current exploration efforts are underway with a 2026 program targeting 60,000 metres of diamond drilling. As of the latest release, roughly 45,000 metres have been completed with seven rigs active.

Financial data shows Sitka Gold held C$44.6 million in cash at December 31, 2025. The company’s MD&A indicates a cash balance of C$43.5 million as of Q1 2026, while an investor presentation reports C$25.0 million in cash as of August 1, 2026. The declining cash balance reflects active exploration spending, which is normal for the company’s current stage, though further financing will likely be needed after the current program concludes.
