Sitka finds visible gold at RC project

Executive Summary

• Sitka Gold reports multiple occurrences of visible gold from surface in the first six diamond drill holes completed at the Contact zone of its RC Gold project.
• Six holes (2,172 m total) intersected broad altered metasediments with quartz‑vein mineralization containing visible gold associated with arsenopyrite and bismuthinite.
• The results expand known gold mineralization to ~900 m × 650 m laterally and to a depth of ~430 m, supporting the potential for additional multimillion‑ounce deposits within the 30,000‑m drill program.

Key Details

• Drill Program Context: Part of a fully financed 30,000‑m diamond drilling campaign; >25,000 m drilled at RC Gold in 2025 to date.
• Contact‑Pukelman Target – Holes Completed: 6 holes, total depth 2,172 m (out of planned 5,000 m).
• Geology Intersected: Broad intervals of strongly altered metasediments cut by quartz‑monzonite and biotite‑feldspar porphyritic dikes; abundant centimetre‑scale sheeted quartz veins.
• Visible Gold Observations: Visible gold present in sheeted quartz veins, frequently associated with arsenopyrite, bismuthinite, and minor scheelite.
• Historical Drilling Comparison: 2010–11 RC Gold reverse‑circulation (1,660 m) and diamond drilling (254 m) identified mineralization up to 450 m south of the Pukelman intrusion; current work shows gold across ~900 m × 650 m area from surface to ~430 m depth.
• Assay Results: Pending for 52 holes across the project, including the Contact‑Pukelman target.
• Resource Context: Existing pit‑constrained resources – Blackjack (1.291 M oz indicated, 1.044 M oz inferred) and Eiger (0.44 M oz inferred). Both are surface‑accessible, potentially open‑pit/minable with heap leaching; gold recoveries up to 94 % from bottle‑roll tests.
• Recent High‑Grade Intercepts (for context):
• DDRCCC‑23‑047 (2023) – 219 m @ 1.34 g/t Au (max 3.11 g/t).
• DDRCCC‑24‑068 (2024) – 678 m @ 1.04 g/t Au (max 17.59 g/t).
• DDRCCC‑25‑075 (Winter 2025) – 352.8 m @ 1.55 g/t Au (max 4.52 g/t).
• Future Plans: Continue oriented diamond drilling to delineate controls on mineralization and test linkage between metasedimentary and intrusion‑hosted zones; complete the remaining ~27,828 m of the 2025 program.

Notable Quotes

“The widespread and robust gold mineralization being intersected in our drilling across this area continues to demonstrate that the RC gold project is a unique gold camp with multiple intrusions that display the potential to host several multimillion‑ounce gold deposits within this relatively small three‑by‑five‑kilometre core area.” – Cor Coe, CEO & Director, Sitka Gold Corp.
