VANCOUVER, CANADA – November 6, 2025: Sitka Gold Corp. (“Sitka” or the “Company”) (TSX-V:SIG) (FSE:1RF) (OTCQB:SITKF) is pleased to announce additional analytical results for seven diamond drill holes completed at the Rhosgobel intrusion target located at its 100% owned, road accessible RC Gold Project (“RC Gold” or the “Project”) within the Yukon’s prolific Tombstone Gold Belt. The 2025 drill program was successfully completed on time and under budget and consisted of 91 diamond drill holes for a total 31,841 metres including 43 holes (12,722 m) at Rhosgobel, 26 holes (10,494 m) at Blackjack/Saddle, 10 holes (4,401 m) at Eiger, 6 holes (2,171 m) at Contact Zone, 3 holes (1,044 m) at Pukelman, 2 holes (606 m) at May-Qu and 1 hole (401 m) at Bear Paw Breccia Zone. Assays are currently pending for 55 drill holes completed at RC Gold.

*Intervals are drilled core length, as insufficient drilling has been completed at this time to determine true widths.
“We are very pleased with the continued success of our drilling at the Rhosgobel discovery, where results from an additional seven drill holes have significantly expanded the discovery footprint,” stated Cor Coe, CEO and Director of Sitka. “The consistently strong gold grades and broad mineralized intervals, such as 107.9 metres of 1.01 g/t gold from surface in DDRCRG-25-014 and 297.0 m of 0.61 g/t Au from surface, including 28.5 metres of 2.20 g/t gold, in hole DDRCRG-25-017, further confirm the strength and continuity of this growing gold system that begins at surface. With visible gold observed in sheeted quartz veining across the entire 1.1 kilometre strike drilled this year and assays now confirming gold mineralization over 575 metres of strike, Rhosgobel is rapidly emerging as a significant new gold discovery within our RC Gold Project. The fact that 16 of the first 17 holes have returned intersections exceeding 100 gram-metres of gold further underscores both the scale and consistency of this system. We eagerly await results from the remaining 26 holes completed at Rhosgobel as we continue to define the size and potential of this exciting new gold zone.”
Figure 1: A plan map of the Rhosgobel Intrusion target showing the diamond drilling completed in 2024 and 2025 along with shallow reverse circulation drill holes completed in 1995. All holes have intersected reduced intrusion-related gold system (RIRGS) style mineralization including centimetre-scale, sheeted, quartz veins and larger, metre-scale quartz, and quartz-tourmaline veins (and breccias) cutting the feldspar megacrystic quartz monzonite intrusion. Multiple occurrences of visible gold have been observed in most of the diamond drill holes completed to date (yellow stars).

Figure 3: A plan map of the broader Rhosgobel Intrusion target area that is supported by a large 2.0 km x 1.5 km gold-in-soil anomaly which covers the central part of the intrusion. While drilling to date has only been focused on the core of this target area, geochemical results from soil sampling have been shown to strongly correlate with in situ gold mineralization at Rhosgobel.
