1911 Gold has released an updated underground mineral resource estimate for the Ogama-Rockland Gold Project in southeast Manitoba, reporting an inferred mineral resource of 3,314,000 tonnes grading 6.68 grams per tonne gold for 712,000 ounces of contained metal.

The underground estimate for the deposit, located approximately 45 kilometres by road southeast of the company’s fully permitted True North mine and mill complex on the Rice Lake property, is reported within stopes designed using Deswik Mineable Shape Optimizer software at a proposed economic cut-off grade of 2.50 grams per tonne gold.

The resource comprises eight main modelled veins and six subordinate parallel veins spanning a strike length of over 1,500 metres and drilled to depths exceeding 600 metres. The database incorporates 99 drill holes totalling 34,977 metres of core length.

The deposit encompasses the historic Ogama and Rockland gold mines, which collectively produced approximately 45,000 ounces of gold at a grade of 11.25 grams per tonne gold between 1948 and 1951 from two main shafts, with mining largely confined to the upper 200 metres of the system.

“The deposit's high-grade profile and significant resource base, open both along-strike and down-dip on multiple veins, highlight the resource growth potential at Ogama-Rockland and the surrounding Rice Lake properties outside the True North mine lease footprint.”

— Shaun Heinrichs, President and CEO

The company plans to conduct a follow-up surface drill program at Ogama-Rockland in the fourth quarter of 2026 to test areas identified for potential resource expansion down-dip and along strike.

The updated estimate will be incorporated into a global resource update scheduled for the fourth quarter of 2026, which will also include a mineral resource update for True North to inform future technical studies. Metallurgical recovery test work is currently underway on a composite sample collected from recent drill core at ALS Canada facilities in Kamloops.
