Sitka Discovers Third Intrusion-Related Gold Deposit; Drills 152.1 Metres of 1.00 g/t Gold from Surface, Including 9.0 Metres of 4.23 g/t Gold, at Its Rhosgobel Target, RC Gold Project, Yukon

Executive Summary

• First 2025 drill holes at the Rhosgobel intrusion returned strong near‑surface gold intercepts, including 152.1 m @ 1.00 g/t Au (9.0 m @ 4.23 g/t Au) and 114.8 m @ 1.11 g/t Au (8.6 m @ 3.50 g/t Au).
• All four drill holes completed to date at Rhosgobel have exceeded 100 gram‑metres (g/t·m) of gold, confirming a third intrusion‑related gold deposit within the RC Gold project.
• Drilling program remains active: 18 holes (~4,593 m) completed at Rhosgobel with assays pending for 14 holes; 30,000 m total program underway across the Clear Creek Intrusive Complex, including new work at the Pukelman target.

Key Details

• Hole DDRCRG‑25‑003: 152.1 m @ 1.00 g/t Au from surface; includes 9.0 m @ 4.23 g/t Au (starting at 89 m) and 10.0 m @ 2.75 g/t Au (starting at 113 m).
• Hole DDRCRG‑25‑005: 114.8 m @ 1.11 g/t Au from surface; includes 14.9 m @ 3.28 g/t Au and 8.6 m @ 3.50 g/t Au (starting at 41 m).
• Assay Status: Results pending for holes DDRCRG‑25‑004, DDRCRG‑25‑006, DDRCRG‑25‑011 and 14 other Rhosgobel holes; also pending for 43 holes across Blackjack‑Saddle‑Eiger zone and Pukelman target.
• Program Scope: Up to 10,000 m of drilling planned at Rhosgobel in 2025; total 30,000 m diamond drill program for RC Gold project underway.
• Rhosgobel Target Geometry: Gold‑in‑soil anomaly ≈2.0 km × 1.5 km; mineralization traced over 900 m strike length and to 450 m depth; visible gold observed in 14 of 18 holes.
• Pukelman Target: Historical intercepts include 10.7 m @ 20.46 g/t Au (CC10‑22) and recent surface grab samples up to 67.9 g/t Au; up to 5,000 m drilling planned in 2025.
• Overall Drill Coverage YTD: 21,347 m in 58 holes across the Clear Creek Intrusive Complex; 4 drill rigs operating (2 at Rhosgobel, 2 at Pukelman).

Notable Quotes

“The strong gold results from initial drilling at Rhosgobel this summer are highly encouraging and further confirm both the scale and strength of gold mineralization that is present across what appears to be a very well‑endowed gold system within the Clear Creek Intrusive Complex,” – Cor Coe, CEO & Director.

“Every hole reported to date from Rhosgobel…has returned intervals that exceed 100 gram‑metres of gold, confirming that another intrusion‑related gold deposit has been discovered.” – Cor Coe, CEO.
