(TSXV: SIG) (FSE: 1RF) (OTCQX: SITKF) (\"Sitka\" or \"Sitka Gold\" or the \"Company\") is pleased to announce positive results from initial metallurgical testwork completed for gold and tungsten recoveries at the newly discovered Rhosgobel Gold Deposit (inferred mineral resource estimate of 2.25 million ounces of gold with 100.68 Mt @ 0.70 g/t Au; see news release dated February 25, 2026) at its flagship RC Gold Project in Yukon. The results of the initial testwork demonstrate robust gold recoveries ranging from 91.8% - 97.3% with an overall average of 94.3% (see Table 3) at Rhosgobel utilizing whole ore bottle roll testing which represents Carbon in Leach (\"CIL\")/Carbon in Pulp (\"CIP\") processes, the most commonly used milling gold recovery method. A high tungsten recovery that averaged 84.7% was achieved with standard grinding and rougher flotation testwork with a very low mass pull of less than 1%. Flotation is a standard method for recovering tungsten from scheelite-bearing deposits and these results demonstrate the potential for tungsten to be a high value by-product of the Rhosgobel gold deposit, where recent assay results have confirmed the presence of significant tungsten mineralization across a broad 850 metre strike length. \"Initial metallurgical testing of gold and tungsten recoveries at Rhosgobel has returned some excellent results with an average recovery of 94.3% for gold and an initial recovery of 84.7% for tungsten,...
