About this update from Sitka Gold Corp.
Updated Rhosgobel Gold Deposit Mineral Resource Estimate consists of a pit-constrained Inferred Mineral Resource of 100.68 million tonnes grading 0.70 g/t gold, 0.90 g/t silver and 0.051% WO3 containing 2,250,000 ounces of gold, 2,926,000 ounces of silver and 51,345 tonnes of WO3 (tungsten trioxide) Total RC Gold Project Mineral Resource Estimate now comprises: 1.29 million ounces gold indicated and 3.83 million ounces gold inferred: 1.29 million ounces gold indicated (39.96 Mt @ 1.01 g/t Au) at Blackjack 3.83 million ounces gold inferred including: 2.25 million ounces (100.68 Mt @ 0.70 g/t Au) at Rhosgobel, 1.04 million ounces (34.60 Mt @ 0.94 g/t Au) at Blackjack, and 0.54 million ounces (32.14 Mt @ 0.52 g/t Au) at Eiger. 2.93 million ounces of silver inferred (100.68 Mt @ 0.90 g/t Ag) at Rhosgobel 51,345 tonnes of WO3 (tungsten trioxide) inferred (100.68 Mt grading 0.051% WO3) at Rhosgobel Initial metallurgical testing at Rhosgobel has returned an average gold recovery of 94.3% using conventional whole ore cyanidation leaching and and an initial recovery of 84.7% tungsten in rougher concentrate using conventional floatation The Rhosgobel deposit was discovered in late 2024 with diamond drilling by Sitka. An additional 41 diamond drill holes were completed in 2025 for a total of 13,422 m of diamond drilling. 2026 Drilling Update 60,000 m diamond drilling program currently underway at RC Gold this year; approximately double the amount of drilling that has been completed at the Project to date Drilling to focus on expanding known resources at the Blackjack, Eiger, and Rhosgobel deposits, all of which remain open, and following up on other high-priority drill targets 30,000 m of drilling is currently underway at Rhosgobel focused on expanding this newly discovered deposit which has a large footprint outlined at surface by a large 1.5 km x 2.0 km gold-in-soil anomaly and geophysics; the deposit remains open in all directions 9,000 m completed in 2026 to date; assays are currently pending for all 2026 drill holes completed to date Vancouver, British Columbia--(Newsfile Corp. - May 14, 2026) - Sitka Gold Corp.
