1911 Gold Corp (TSX-V:AUMB, OTCQB:AUMBF, FRA:2KY) said its Ogama-Rockland project in Manitoba now hosts 712,000 ounces of gold, an inferred resource grading 6.68 grams per tonne, a discovery the company says could grow further as drilling continues to test its open extensions.
The estimate is based on stopes designed using Deswik's Mineable Shape Optimizer at a proposed economic cut-off grade of 2.5 grams per tonne gold.
The deposit remains open both along strike and down dip on multiple veins, and the company has identified gaps within the current resource envelope where additional drilling could add resources.
Ogama-Rockland sits roughly 45 kilometres by road southeast of 1911 Gold's fully permitted True North mine and mill complex on its wholly owned Rice Lake property.
Grades were estimated into a block model using ordinary kriging, the company said, with the methodology validated against nearest neighbour and inverse distance squared methods.
The drill database used for the estimate comprised 99 holes totaling 34,977 metres and 19,923 assay results, including eight surface holes drilled in 2025 and 2026 to test and confirm the geology model.
Shaun Heinrichs, 1911's CEO, said the updated estimate is an important step in advancing the company's district-scale opportunity centered on the True North Complex.
"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," the CEO told shareholders. "We look forward to advancing Ogama-Rockland alongside our flagship True North Gold Project, as we progress the development of an expanded gold district in Manitoba."
The company has planned a follow-up surface drilling program at Ogama-Rockland for the fourth quarter of 2026 to test areas identified for potential resource expansion.
The updated Ogama-Rockland resource will be folded into a global resource update expected in the fourth quarter of 2026, which will also include an updated estimate for True North.
Current drilling at True North includes resource expansion work alongside exploration of the San Antonio Mine West, San Antonio Mine Southeast and Shore targets, which may inform future mine plans and technical studies supporting a potential production decision at True North in 2027.
The historic Ogama and Rockland mines produced approximately 45,000 ounces of gold at a grade of 11.25 grams per tonne between 1948 and 1951, with mining confined to the upper 200 metres of the deposit.
