RC Gold Project Program Produces Best Results To Date

VANCOUVER - Sitka Gold Corp. reported on the 2025 diamond drilling campaign at its road accessible RC Gold Project located approximately 100 km east of Dawson City in Yukon's prolific Tombstone Gold Belt. Results from DDRCCC-25-075 (Hole 75) returned 352.8 metres of 1.55 g/t gold, including 108.9 metres of 3.27 g/t gold and 45.0 metres of 4.52 g/t gold. Hole 75, which had over 130 instances of visible gold observed during logging of the drill core, was the first of two diamond drill holes completed at RC Gold during this year's winter drilling campaign. DDRCCC-25-076 ("Hole 76"), the second drill hole completed this winter, was drilled to a depth of 810.8 metres, the deepest hole ever drilled at Blackjack, for a total of 1,526.8 metres of diamond drilling completed during the winter drilling campaign. Assays are currently pending for Hole 76 where over 60 instances of visible gold were observed.

"2025 is off to an excellent start with the first drill hole of the year producing some of the best gold intercepts encountered to date at our RC Gold project," said, Cor Coe, Director and CEO. "Initial observations of Hole 75, including numerous instances of visible gold, indicated that we had drilled through an area of strong gold mineralization and this has now been confirmed by these assay results. Hole 75 continues to highlight the quality of the gold system present at the Blackjack deposit while greatly expanding the higher-grade gold zone discovered at depth late last year in Hole 68 which remains open both laterally and to depth. The increasing gold values we are seeing at depth appear to have the grades and continuity required for a possible underground extraction scenario below the current pit constrained resources at Blackjack and suggest that we could be getting closer to the source of the Blackjack gold deposit as we drill deeper into the system.

These results build on our previous success at Blackjack and show that we have really just started to unlock the potential of this large, contiguous 431 square kilometre gold district where 11 intrusions have been identified on surface to date, all of which have associated intrusion related gold mineralization present and are considered high-priority targets for future exploration. The fact that we have been able to produce a pit-constrained mineral resource estimate of 1.3 million ounces of indicated gold at 1.01 g/t gold and 1.0 million ounces of inferred gold at 0.94 g/t gold at the Blackjack deposit with just 18,799 metres of drilling underscores the potential of the additional 30,000 metres of drilling planned at RC Gold for this year. We are now waiting on the results from hole 76, which again produced multiple instances of visible gold and extended the vertical depth of mineralization at the Blackjack zone to over 700 metres from surface, being the deepest drill hole completed to date at the RC Gold project. 2025 is shaping up as an exciting and pivotal year for Sitka as we push to continue creating shareholder value by rapidly advancing our flagship RC Gold project."
