Sitka Gold reported an updated Mineral Resource Estimate for the Rhosgobel deposit for the first time, including tungsten and silver that consists of a pit-constrained Inferred Mineral Resource of 100.68 million tonnes grading 0.70 g/t Au, 0.90 g/t Ag and 0.051% WO3, containing 2,250,000 oz Au, 2,926,000 oz Ag and 51,345 tonnes of WO3 (tungsten trioxide).
Beyond the Headline
Sitka Gold reported an updated Mineral Resource Estimate for the Rhosgobel deposit for the first time, including tungsten and silver that consists of a pit-constrained Inferred Mineral Resource of 100.68 million tonnes grading 0.70 g/t Au, 0.90 g/t Ag and 0.051% WO3, containing 2,250,000 oz Au, 2,926,000 oz Ag and 51,345 tonnes of WO3 (tungsten trioxide).
Total RC Gold Project Mineral Resource Estimate now comprises:
- 29 million ounces gold indicated and 3.83 million ounces gold inferred:
- 29 million ounces gold indicated (39.96 Mt @ 1.01 g/t Au) at Blackjack
- 83 million ounces gold inferred including:
- 25 million ounces (100.68 Mt @ 0.70 g/t Au) at Rhosgobel,
- 04 million ounces (34.60 Mt @ 0.94 g/t Au) at Blackjack, and
- 54 million ounces (32.14 Mt @ 0.52 g/t Au) at Eiger.
- 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 an initial recovery of 84.7% tungsten in rougher concentrate using conventional flotation.
A 60,000 m diamond drilling program is currently underway at RC Gold this year which is approximately double the amount of drilling that has been completed at the Project to date. Drilling is focusing on expanding known resources at the Rhosgobel, Blackjack and Eiger deposits, all of which remain open, and following up on other high-priority drill targets. 30,000 m of this planned drilling, now underway, will be at Rhosgobel, focused on expanding this newly discovered deposit which has a large footprint outlined at surface by a 1.5 km x 2.0 km gold-in-soil anomaly and geophysics. The deposit remains open in all directions
Thus far 9,000m of drilling has been completed in 2026 with assays pending for all 2026 drill holes completed to date.
The mineral resource update and initial metallurgical testing at Rhosgobel confirms the potential for tungsten to be an important by-product in this deposit. There will be continuous drill results coming out over the summer and into this fall from this major drill program with the potential for major resource expansion in all three known deposits as well as additional discoveries on other high-priority drill targets.
