Sitka Updates Rhosgobel Resource Estimate

Why It Matters

Adding tungsten—a critical mineral—to a gold‑centric deposit strengthens the project's strategic relevance and diversifies its revenue potential, making it more attractive to investors and domestic supply chains.

Key Takeaways

• Rhosgobel now holds 2.93 M oz inferred silver, 51 k t tungsten.
• Higher‑grade gold core >1 g/t extends to ~300 m depth.
• Gold recovery 94.3%; tungsten recovery 84.7% in tests.
• 30,000 m drilling planned, tripling total exploration depth.
• Project in Yukon’s Tombstone Gold Belt, near Eagle and Brewery Creek mines.

Pulse Analysis

Sitka Gold Corp. has refreshed the mineral resource estimate for its Rhosgobel deposit at the RC Gold project in Yukon’s historic Tombstone Gold Belt. The update not only confirms the original 2.25 million ounces of inferred gold but also adds 2.93 million ounces of inferred silver and roughly 51,000 metric tons of tungsten trioxide (WO₃). The deposit, uncovered through 72 drill holes—including legacy reverse‑circulation work from 1995 and recent core drilling—covers a 447‑square‑kilometer land package situated between the Eagle Gold and Brewery Creek mines, positioning it as a central hub for the district‑scale property.

The inclusion of tungsten transforms Rhosgobel from a pure precious‑metal play into a multi‑metal asset with a strategic critical‑minerals component. In the United States, domestic tungsten sources are scarce, and the metal is essential for defense, aerospace, and clean‑energy applications. Initial metallurgical testing shows a robust 94.3 % gold recovery via conventional cyanidation and an 84.7 % tungsten recovery through flotation, suggesting a viable by‑product stream. While silver processing data remain pending, the projected flow sheet of gravity, flotation, and cyanidation circuits points to a potentially lucrative, diversified revenue model.

Sitka plans an aggressive 30,000‑meter drilling campaign at Rhosgobel this year, more than tripling the total depth explored to date, alongside additional programs across the Blackjack‑Eiger, Pukelman‑Contact, and Bear Paw targets. This expanded effort aims to delineate the higher‑grade near‑surface core and test the broader 1 km × 2 km gold‑in‑soil anomaly, which could substantially increase the resource footprint. Investors are likely to view the combined gold‑silver‑tungsten package as a hedge against commodity volatility, potentially lifting the company’s market valuation and attracting strategic partners seeking secure critical‑mineral supplies.
