Generation Mining Secures $240 Million Stream with Wheaton Precious Metals

TORONTO, Dec. 22, 2021 - Generation Mining Ltd. (TSX: GENM; OTCQB: GENMF) ("Gen Mining" or the "Company") is pleased to announce that it has agreed to enter into a definitive Precious Metal Purchase Agreement (the "Marathon PMPA") with Wheaton Precious Metals Corp. ("Wheaton") in respect to the Marathon Palladium Copper project in Northwestern Ontario (the "Marathon Project"). The Marathon PMPA becoming effective is subject to the closing of Gen Mining's acquisition of the remaining 16.5% interest in the Marathon Project from Sibanye Stillwater Ltd. (see Press Release dated December 8, 2021).

Pursuant to the PMPA, Wheaton will pay Gen Mining a total upfront cash consideration of C$240 million, C$40 million of which will be paid on an early deposit basis prior to construction to be used for development of the Marathon Project, with the remainder payable in four staged installments during construction, subject to various customary conditions being satisfied.

"Entering into this agreement with the world's largest precious metals streaming company validates the potential economics of the Marathon Project and is a significant milestone for the Company and our shareholders," said Jamie Levy, Gen Mining President and CEO. "This stream represents a key cornerstone financing commitment for the ultimate project financing package. Working closely with our financial advisors, Endeavour Financial, we will now focus on sourcing the remaining key financial components of the project financing including project debt, offtake agreements and equipment financing."

MARATHON PMPA TRANSACTION DETAILS

• Under the Marathon PMPA, Wheaton will purchase 100% of the payable gold production until 150 thousand ounces ("koz") have been delivered, thereafter dropping to 67% of payable gold production for the life of the mine; and 22% of the payable platinum production until 120 koz have been delivered, thereafter dropping to 15% for the life of mine.
• Wheaton will pay Gen Mining a total upfront cash consideration of C$240 million, C$40 million of which will be paid on an early deposit basis prior to construction to be used for development of the Marathon Project, with the remainder payable in four staged installments during construction, subject to various customary conditions being satisfied and pre-determined completion tests.
