About the Company

Generation Mining’s focus is the development of the Marathon Project, a large undeveloped

copper-palladium deposit in Northwestern Ontario. The Marathon Property covers a land

package of approximately 26,000 hectares, or 260 square kilometers. Generation Mining is

dedicated to fostering a greener future by promoting sustainability, empowering communities,

and delivering value to our stakeholders.

The Feasibility Study (the “Technical Report”) estimated a Net Present Value (using a 6%

discount rate) of C$1.07 billion, an Internal Rate of Return of 28%, and a 1.9-year payback based

on the 3-yr trailing average metal prices at the effective date of the Technical Report. Over the

anticipated 13-year mine life, the Marathon Project is expected to produce 2,161,000 ounces of

palladium, 532 million lbs of copper, 488,000 ounces of platinum, 160,000 ounces of gold and

3,051,000 ounces of silver in payable metals. For more information, please review the Feasibility

Study filed under the Company's profile at www.sedarplus.ca or on the Company's website at
