1911 Gold Corporation reported metallurgical gold recovery results averaging 93.7% for its True North Gold Project and 96.3% for the Ogama-Rockland Gold Project in southeast Manitoba, alongside a successful commissioning run of the True North primary ball mill.

The testing evaluated mineralized samples from the True North L10 Zone and recent drill core from Ogama-Rockland under operating parameters reflecting the True North processing plant. A 130-kilogram sample collected from Level 16 of the L10 Zone at a head grade of 1.82 grams per tonne gold yielded an average recovery of 51.0% through gravity concentration. Flotation and cyanide leaching of the reground flotation concentrate produced total recoveries averaging 93.7%.

Preliminary test work on an Ogama-Rockland composite sample, grading 4.65 grams per tonne gold, achieved an 82.0% gravity recovery and an overall recovery of 96.3% using a gravity-flotation-regrind-leach flowsheet.

The company also completed a test run of the True North primary ball mill on August 10, 2026, following the installation of new liners, lifters, and a gear lube system. The work prepares the plant for test mining and bulk sampling programs scheduled for later in the year.

A Bond ball mill work index test on the True North composite measured 14.1 kilowatt-hours per tonne, indicating the material sits at the lower end of the medium hardness range.

1911 Gold holds a 100% interest in True North, which features a fully built and permitted mine and a 1,300 tonne-per-day processing facility being advanced toward a restart. The Ogama-Rockland Gold Project lies approximately 45 kilometres southeast of the True North complex on the Rice Lake property and hosts an inferred mineral resource of 3,314,000 tonnes grading 6.68 grams per tonne gold for 712,000 ounces of contained metal.

“We are pleased to provide results from metallurgical test work for True North, confirming excellent gold recoveries, with a significant amount of gold recovered through the gravity stage, and the remainder readily leachable in the flotation concentrate. Preliminary test work for Ogama-Rockland provided encouraging results and confirmed the clean nature of material which is amenable to high recoveries at the True North mill.”

Additional trade-off studies, variability test work, and further comminution and environmental characterization are required across multiple mineralized zones to determine optimal operating conditions as the company advances technical studies to support a potential production decision in 2027.
