The company is currently conducting a Preliminary Economic Assessment (PEA) for an underground mine producing up to 10,000 tonnes per day, specifically targeting material grading over 2.5 g/t gold .

Tudor has filed for a permit to construct an underground ramp to access the high-grade SC-1 Zone, which would allow for more efficient, year-round drilling.

A recent regulatory decision stalled a competing permit from Seabridge Gold for tunnel construction through Tudor's claims, providing Tudor with "greater legal certainty" for its own development plans.

As of January 2026, the Goldstorm deposit hosts an Indicated Resource of 24.9 million ounces of gold , 148.7 million ounces of silver, and 3.048 billion pounds of copper.
