Generation Mining Provides Update on Regional Exploration Program

Generation Mining Limited has completed its 2026 summer exploration program at the Marathon Property, focusing on regional soil sampling, geological mapping, and prospecting across the Four Dams, Lacobeer, Skipper, and Boyer prospects. Preliminary soil assay results indicate elevated copper values along the Layered Series–Marathon Series contact.

To date, 909 of 1,786 samples have been analyzed, with the following intercepts recorded:

• 12 samples returning >300 ppm Cu
• 8 samples exceeding 500 ppm Cu
• Maximum recorded value of 3,280 ppm Cu

The company is conducting a geological reinterpretation of the underexplored Layered Series copper potential with Big Rock Exploration. Additionally, plans are in place to relog and sample historical drill core at the Sally Deposit in Q1 2027 to refine exploration targets. QA/QC procedures were reviewed and deemed acceptable by independent consultants.

The results are incremental and in line with expectations for a pre-production development-stage company advancing regional exploration. The update does not alter the project's fully funded construction status or near-term cash flow profile. No material impact on valuation or share price is expected, as the findings serve as a positive confirmation of the project's broader mineralized footprint.

Generation Mining Limited (GENM) is a Canadian mining company focused on the Marathon Copper-Palladium Project in Northwestern Ontario. The project is 100% owned, fully permitted, and shovel-ready, with construction officially commencing in October 2026.

A Feasibility Study effective November 1, 2024, outlines a 13-year mine life with an NPV of $1.07B at a 6% discount, an IRR of 28%, and a 1.9-year payback period. Estimated production includes:

• ~2.16M oz Palladium
• 532M lbs Copper
• 488K oz Platinum
• 160K oz Gold
• 3.05M oz Silver

Commercial production is targeted for Q3 2029.
