Sitka Drills 145.0 Metres of 0.92 g/t Gold, Including 15.5 Metres of 4.22 g/t Gold at Blackjack, and Provides Update on Its RC Gold Project, Yukon

Executive Summary

• Sitka Gold reports significant near‑surface gold intercepts from its ongoing 30,000 m diamond drilling program at the RC Gold Project, notably 145 m @ 0.92 g/t Au (incl. 41.8 m @ 1.94 g/t and 15.5 m @ 4.22 g/t) in hole DDRCCC‑25‑092 at Blackjack.
• New high‑grade zones identified in the Saddle zone (e.g., 34.4 m @ 1.47 g/t, 27.7 m @ 1.90 g/t, 26.7 m @ 1.82 g/t) and expanding mineralization at Rhosgobel, Eiger, Pukelman/Contact and Bear Paw targets.
• To date 81 holes (29,264 m) have been completed across the Clear Creek Intrusive Complex; drilling remains under budget, ahead of schedule, and will extend beyond the planned 30,000 m for 2025.

“The Saddle zone in particular is quickly emerging as an important contributor to the gold endowment within this corridor… These impressive results underscore the potential for Saddle to add significant near‑surface ounces while reducing stripping in future resource estimates.” – Cor Coe, CEO & Director
