The Company acquired, on an arm's length as is where is basis, all issued and outstanding common shares (and all assets and liabilities) of Sojitz Moly Resources Inc., a wholly-owned subsidiary of Sojitz, which changed its name to Moon River Molybdenum BC Ltd. ("Moon River BC").

Paul Parisotto, President and Chief Executive Officer of Moon River, said, "We are delighted to complete this transaction and look forward to working with Centerra on the Endako Mine Complex. Our 25% interest in the Endako Mine Complex combined with our right to develop the Davidson molybdenum deposit, both of which are located in close proximity in central British Columbia, provides a compelling opportunity in the molybdenum space."

Moon River BC is the holder of a 25% participating interest in the Endako Mine Complex pursuant to an exploration, development and mine operating agreement dated as of June 12, 1997 (the "JVA") entered into between Moon River BC and Thompson Creek Mining Ltd. (now Thompson Creek Metals Company Inc.) ("TCM"), a subsidiary of Centerra Gold Inc.

Sojitz provided funding to Moon River BC in the aggregate of $41,886,494 of which:

• $15,475,000 represent Moon River BC's current portion of the environmental reclamation security in respect of the Endako Mine Complex;
• $24,411,494 have been deposited into trust with TSX Trust Company pursuant to the terms of a trust indenture to fund Moon River BC's future care and maintenance costs and/or future increases to Moon River BC's responsibility for 25% of the environmental and asset retirement obligations for the Endako Mine Complex (this amount is net of property costs and expenses for 2024 to date); and
• $2,000,000 have been deposited in Moon River's bank account.

As consideration for the above, Moon River has paid Sojitz $1.00 on closing and agreed to pay Sojitz four annual earn-out payments beginning on the third anniversary of completion of the acquisition and ending on the sixth anniversary of completion of the acquisition of up to $10,000,000 in aggregate subject to the future price of molybdenum as follows.

The earn-out payments payable by the Company to Sojitz are payable irrespective of whether or not the Endako Mine Complex is in production at such time. As at May 30, 2024, the date hereof, the market price of MO is US$22.69 per lb. based on information from the London Metals Exchange.

Each earn-out payment shall be determined based on the average market price of molybdenum for a period from the anniversary of the closing date of the acquisition in the previous calendar year to the date immediately prior to the next anniversary date, in accordance with the following table:
