About the Company

Gen Mining’s focus is the development of the Marathon Project, a large undeveloped palladium-copper deposit in Northwestern Ontario. The Company released the results of the Feasibility Study on March 3, 2021 and published the NI43-101 Technical Report dated March 25, 2021. The Marathon Property covers a land package of approximately 22,000 hectares, or 220 square kilometres. Gen Mining owns a 100% interest in the Marathon Project.

The Feasibility Study in respect of the Marathon Project estimated that at US$1,725/oz palladium, and US$3.20/lb copper, Marathon’s Net Present Value (at 6% discount rate) is approximately C$1.07 billion with a payback of 2.3 years and an Internal Rate of Return of 30%. Upfront capital costs were estimated at C$665 million, net of equipment financing and pre-completion operating costs and revenues. The mine would produce an estimated 245,000 palladium equivalent ounces per year over a 13-year mine life at an All-In Sustaining Cost of US$809 per palladium-equivalent ounce. Over the 13-year mine life the Marathon Project is estimated to produce 1,905,000 ounces of palladium, 467 million lbs of copper, 537,000 ounces of platinum, 151,000 ounces of gold and 2,823,000 ounces of silver. For more information, please review the detailed Feasibility Study dated March 25, 2021, filed under the Company’s profile at SEDAR.com.

Final Ministerial decisions in the Environmental Assessment process are expected to be delivered on or before November 30, 2022. Upon receipt of favourable decisions from the Ministers and the required permits, the Company anticipates starting construction late in the first quarter of 2023.
