VANCOUVER, BC , Aug. 20, 2026 /CNW/ -- 1911 Gold Corporation (" 1911 Gold " or the " Company ") (TSXV: AUMB) (OTCQX: AUMBF) (FRA: 2KY) is pleased to report the results of metallurgical gold recovery test-work performed on mineralized samples from the Company's True North Gold Project (" True North "), centrally located within the 60,000-ha land package, and the Ogama-Rockland Gold Project (" Ogama-Rockland "), located approximately 45 kilometres (" km ") by road southeast of True North, on its 100%-owned Rice Lake property in southeast Manitoba, Canada, as well as an update on the recommissioning of the True North mill.

Highlights:

True North Gold ("Au") recoveries included the following highlights:

Metallurgical test work on a 130 kilogram ("kg") sample with a measured head grade of 1.82 grams per tonne ("g/t") Au collected from underground on Level 16 from the L10 Zone in conditions the True North Mill previously operated at, include the following highlights: Total Au recoveries averaging 93.7 percent ("%")

Recovery averaging 51.0% Au by gravity concentration

An average of 44.5% of gold reporting to the flotation concentrate

Leach recovery averaging 95.5% Au from the reground flotation concentrate

24-to-48-hour leach residence time and moderate to low reagent consumption

Ball Mill Work Index ("BMWI") of 14.1 kilowatt hours per tonne ("kWh/t") indicating the low end of the medium hardness range, no acid-generating and deleterious metal leaching potential

Ogama-Rockland Au recoveries included the following highlights:

Preliminary metallurgical test work on a composite sample with a measured head grade of 4.65 g/t Au from recent drill core in conditions the True North mill previously operated at, include the following highlights: Total Au recovery of 96.3% Au based on a Gravity-Flotation-Regrind-Leach flowsheet
