About McFarlane Lake Mining Ltd.

McFarlane Lake is a Canadian gold exploration company focused on advancing its flagship Juby gold project, located near Gowganda, Ont., within the established Abitibi greenstone belt. The Juby gold project hosts a current (effective Sept. 29, 2025) National Instrument 43-101-compliant mineral resource estimate of 1.01 million ounces of gold in the indicated category at an average grade of 0.98 gram per tonne gold (31.74 million tonnes) and an additional 3.17 million ounces of gold in the inferred category at an average grade of 0.89 g/t gold (109.48 million tonnes). The estimate was calculated using a long-term gold price of $2,500 (U.S.) per ounce, applying cut-off grades of 0.25 g/t gold for open pit and 1.85 g/t gold for underground resources.

A sensitivity analysis completed at a higher gold price of $3,750 (U.S.) per ounce resulted in an indicated mineral resource of 1.20 million ounces grading 0.94 g/t gold (39.51 million tonnes) and an inferred mineral resource of 4.23 million ounces grading 0.85 g/t gold (154.50 million tonnes) applying cut-off grades of 0.25 g/t gold for open pit and 1.15 g/t gold for underground resources.

The independent MRE was prepared by BBA E&C Inc. in accordance with National Instrument 43-101 (Standards of Disclosure for Mineral Projects). The full technical report supporting the resource estimate was filed on SEDAR+ on Nov. 21, 2025, and is also available on the company's website.

McFarlane Lake is actively executing an exploration drilling program and additional technical studies at the Juby project to further evaluate and advance this large-scale gold system.

In addition to Juby, McFarlane Lake holds a portfolio of 100-per-cent-owned gold assets across Ontario, including the past-producing McMillan gold mine and Mongowin properties located approximately 70 kilometres west of Sudbury and the Michaud/Munro properties located 115 km east of Timmins. McFarlane Lake is a reporting issuer in Ontario, British Columbia and Alberta.
