Sitka Drills 121.0 Metres of 0.75 g/t Gold and 26.0 Metres of 1.28 g/t Gold Within 249.9 Metres of 0.58 g/t Gold, Significantly Expanding Mineralization Beyond the Current Resource Boundary at Its Eiger Deposit, RC Gold Project, Yukon

On December 2, 2025, Sitka Gold announced drill results from its Eiger deposit at the RC Gold Project in Yukon. The key highlight was from step-out drill hole DDRCCC-25-109, which intersected a broad zone of 249.9 metres grading 0.58 g/t gold. This included a higher-grade interval of 121.0 metres of 0.75 g/t gold and a sub-interval of 26.0 metres of 1.28 g/t gold.

This drilling successfully expanded mineralization approximately 325 metres beyond the current Mineral Resource Estimate (MRE) boundary for the Eiger deposit. The company notes that these results suggest a higher-grade component may be developing at depth, similar to what has been observed at the nearby Blackjack deposit. The mineralization at Eiger remains open in all directions. Assays for 38 additional drill holes from the 2025 program are still pending.

The news is positive and aligns with the company's successful exploration strategy. Expanding the Eiger deposit, even with grades that are lower than the flagship Blackjack deposit, is crucial for building the overall scale and potential mine life of the RC Gold Project. The intercept of 249.9 metres of 0.58 g/t gold is a notable improvement over the Eiger deposit's current inferred resource grade of 0.50 g/t gold. The suggestion of a higher-grade component developing at depth is an encouraging sign that could enhance the deposit's economics.

However, in the context of Sitka's recent transformative year, this news is considered routine. The market has been conditioned by a series of high-impact events, including a major resource update in January, the discovery of a significant new zone at Rhosgobel with Blackjack-like grades, and a very large C$30.5 million financing completed at a premium in October/November.

While the Eiger results are solid and continue to build value, they do not fundamentally change the investment thesis in the way the Blackjack deep high-grade intercepts, the Rhosgobel discovery, or the major financing did. The market now expects good results from Sitka's drilling, and this release meets those expectations. It methodically adds ounces and demonstrates the potential of the broader mineralized system. The primary value driver remains the expansion of the higher-grade Blackjack deposit and the delineation of the new, high-potential Rhosgobel discovery. Therefore, the impact is positive but routine.

Sitka Gold Corp. is a Canadian junior mineral exploration company focused on its 100%-owned, 431-square-kilometre RC Gold Project in the Yukon's Tombstone Gold Belt. This district-scale project hosts a large intrusion-related gold system with multiple deposits and discoveries.

The flagship asset is the Blackjack deposit, which hosts a pit-constrained NI 43-101 compliant resource of 1.3 million ounces of gold at 1.01 g/t in the Indicated category and 1.0 million ounces at 0.94 g/t in the Inferred category. The project also includes the Eiger deposit (440,000 ounces Inferred at 0.50 g/t) and several recent discoveries, most notably Rhosgobel, which is demonstrating grade and scale comparable to Blackjack. The project is road-accessible and located between Victoria Gold's Eagle Gold mine and a past-producing Brewery Creek mine.
