Artificial Intelligence Review Planned for McFarlane's Gold Resource Property at High Lake

TORONTO, October 3, 2023 - McFarlane Lake Mining Ltd. (NEO:MLM)(OTCQB:MLMLF) ("McFarlane Lake" or "McFarlane" or "the Company"), a Canadian gold exploration and development company, today announced that it has commissioned a full geological compilation of all available historical and current information on its High Lake property to generate a digital dataset to help generate and prioritize exploration targets through the use of artificial intelligence.

The data compilation work is being carried out by Orix Geoscience and includes the High Lake property and the surrounding area. The scope will involve an analysis of historical drill logs, geological maps, geophysical survey data, surface geochemistry samples, and data from the Company's recent drilling campaigns. The Company is also reviewing proposals to deploy artificial intelligence to analyze the resulting comprehensive dataset to focus and prioritize future drilling targets.

"At High Lake's Purdex Zone, we have identified a high-grade gold resource with significant potential for expansion. By compiling the historical exploration results with our recent drilling and geophysical results into one comprehensive dataset, we will be able to optimize our future exploration efforts," said Roger Emdin, Chief Operating Officer of McFarlane Lake. "With recent breakthroughs of applying AI to mineral exploration, we expect that we will be able to further advance this attractive property by identifying additional mineralization targets."

In July 2023, McFarlane Lake filed an NI 43-101 compliant technical report that identified 96,200 Inferred ounces and 45,800 Indicated ounces of gold at a grade of 10.43 grams per tonne of gold and 9.38 grams per tonne of gold, respectively, in the Purdex Zone on the High Lake property.
