(Kitco News) Sitka Gold says its RC Gold project in Yukon’s Tombstone Gold Belt now hosts more than 5 million ounces of gold resources after the company announced a maiden mineral resource estimate for the Rhosgobel deposit on Feb. 25, 2026, marking the latest expansion of the district-scale discovery.
The updated mineral resource estimate totals 1.29 million ounces of gold indicated and 3.83 million ounces inferred across three deposits at RC Gold: Blackjack, Rhosgobel, and Eiger. The maiden Rhosgobel resource accounts for 2.25 million ounces inferred grading 0.70 g/t gold from surface, defined from about 15,400 meters of drilling completed between late 2024 and 2025.
Speaking with Kitco Mining at the PDAC convention in Toronto, Sitka Gold CEO Cor Coe said the project reflects the scale potential typical of intrusion-related gold systems found across Yukon and Alaska.
“You look at Fort Knox, you look at the Eagle Mine, Dublin Gulch. You look at Valley, five to 10 million ounces is not uncommon,” Coe said.
RC Gold spans a large land package where Sitka has identified 11 intrusions associated with gold mineralization, with deposits now outlined at three of them. The most recent growth has come from Rhosgobel, which Coe said moved from discovery drilling to a multi-million-ounce resource within a single field season.
“15,000 meters to end up with a couple million ounces of gold,” Coe said, noting a timeframe of “basically four months of drilling.”
Sitka has drilled just under 60,000 meters across the project since exploration began in 2020 and plans another 60,000 meters of diamond drilling in 2026, roughly doubling the amount drilled to date. The program will focus primarily on expanding the Blackjack, Eiger, and Rhosgobel deposits while testing additional targets across the property.
“This drilling is designed to build ounces. It’s not designed to be wildcat drilling,” Coe said.
Initial metallurgical tests from the Rhosgobel deposit returned gold recoveries of 89% and 96%, indicating the mineralization is not refractory. The company is also evaluating tungsten mineralization associated with scheelite identified in the system, which could potentially provide a byproduct credit pending further analysis.
The company believes continued drilling could position RC Gold for the next stage of technical work. “We think that we’re going to end up with an inventory of gold that triggers us to be comfortable to go into a PEA-type study next year at this time,” Coe said.
