The Transaction was completed in accordance with the terms and conditions set out in the acquisition agreement (the “Acquisition Agreement”) dated December 8, 2021 between the Company, Stillwater, and Generation PGM Inc.

The common shares issued pursuant to the Transaction are subject to a statutory hold period in Canada of four months and one day, as well as certain contractual lock-up and resale restrictions for a period of 18 months. The closing of the Transaction has received conditional approval, but remains subject to receipt of final approval, from the Toronto Stock Exchange.

The Company now holds 100% of the Marathon Project, and the joint venture agreement dated July 10, 2019 between Stillwater and Gen Subco has been terminated in accordance with its terms.

Prior to the closing of the Transaction, Sibanye-Stillwater (including its affiliates) owned 11,053,795 common shares of the Company, representing approximately 7.34% of the Company’s issued and outstanding Common Shares on a non-diluted basis. Upon completion of the Transaction, Sibanye-Stillwater (including its affiliates) now owns 32,813,127 common shares of the Company, representing approximately 19.1% of the issued and outstanding common shares of the Company on a non-diluted basis.

A copy of the early warning report will be available on the Company’s issuer profile on SEDAR at www.sedar.com.

“In addition to now holding a 100% ownership interest in the Marathon Project, the completion of the Transaction also allows us to proceed with the recently-announced streaming transaction with Wheaton Precious Metals and we expect it to be beneficial in negotiating with other lenders to finance construction of the Marathon Project,” said Jamie Levy, Gen Mining President and CEO. “Gen Mining is honored to have Sibanye-Stillwater as an important shareholder in the Company going forward.”

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$1725/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%. Up front capital costs were estimated at C$665 million. 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.
