Rouyn resource and setting

• Rouyn resource totals 1.66Moz at 3.28g/t Au, with ~60% indicated; estimate comprises 976koz indicated and 690koz inferred.

• The project spans a ~7km mineralised corridor along the Cadillac Break, with multiple deposits and historic mines; mineralisation remains open along strike and at depth.

• Rouyn is 4km from Rouyn-Noranda, a mining city of 45,000 with an established workforce, airport, roads, power and mining services.

• The geology is presented as consistent with established Abitibi orogenic gold systems; nearby examples include LaRonde, Westwood and Kerr-Addison.

Exploration and drilling

• Decades of historic drilling are being integrated with new results; the interpretation emphasizes broad mineralised envelopes hosting higher-grade shoots and improving continuity.

• Deeper intercepts include 97.50m at 1.04g/t Au from AS-26-787 and 49.95m at 1.12g/t Au from AS-26-788.

• A 45,000m drilling program is underway with two rigs; new Mineral Resource Estimate work was targeted for Q1 2027.

Value creation and development path

• The stated value strategy combines Mineral Resource growth with narrowing the valuation gap to increase ounces and value attributed per ounce.

• As at 20 October 2026, market capitalisation per total resource ounce was A$39.48 versus a peer-group average of A$165.93.

• The proposed progression runs from understanding the system and earning community trust to growing the resource, demonstrating economics and building a mine.
