Lac Gold (LAC) Investor presentation summary

Strategic positioning in a premier gold region

• Located in the Abitibi region, a world-class gold province with over 200Moz historic production and robust mining infrastructure, including workforce, mills, and transport links.

• The Rouyn Gold Project is situated along the Cadillac Break, a prolific structural corridor hosting multiple historic and active gold mines.

Resource scale and geological potential

• Rouyn Gold Project hosts a mineral resource of 15.8Mt at 3.28g/t for 1,666,000oz Au (April 2025), with mineralisation open at depth and along strike.

• The project covers a ~6km mineralised corridor with multiple untested targets and historic mines, indicating significant exploration upside.

• Modern geological approaches are revealing broad mineralised envelopes and high-grade shoots, with increasing continuity and predictability.

Exploration progress and results

• Recent drilling has delivered wide zones of consistent mineralisation and high-grade intercepts, such as 29.15m @ 4.96g/t Au and 7.00m @ 16.10g/t Au.

• Every drill program is strengthening geological understanding and supporting the resource growth model.
