Copper Mountain Mining Receives Bondholder Approval for the Sale of the Eva Copper Project and the Australian Exploration Tenements and Announces Bond Buyback Offer

VANCOUVER, BC, Nov. 28, 2022 /PRNewswire/ - Copper Mountain Mining Corporation (TSX: CMMC) (ASX: C6C) (the "Company" or "Copper Mountain") is pleased to announce that it has received bondholder approval ("Bondholder Approval") under its US$250 million senior secured bonds (the "Bonds") for the previously announced sale of its wholly-owned Eva Copper Project and its 2,100km² exploration land package in Queensland, Australia (the "Transaction") to Harmony Gold Mining Company Limited (JSE: HAR) (NYSE: HMY) ("Harmony"). See Copper Mountain's press release dated October 6, 2022 ("Copper Mountain Mining Announces Agreement to Sell the Eva Copper Project and the Australian Exploration Tenements for Total Consideration of up to US$230 Million") for additional details regarding the Transaction.

The receipt of Bondholder Approval is a condition to the closing of the Transaction. The closing of the Transaction remains subject to certain customary conditions, including Harmony obtaining written correspondence from the Foreign Investment Review Board (FIRB) in Australia that the Australian Government has no objections under the Foreign Acquisitions and Takeovers Act 1975. The Transaction is expected to close no later than the first quarter of 2023.

Summary of Bond Buyback Offer

In connection with obtaining the Bondholder Approval, the Company has agreed, within 30 days after completion of the Transaction, to:

• Pay a one-time amendment fee of 0.25% of the nominal amount of the outstanding Bonds, on a pro rata basis, to the bondholders; and
• Make an offer to buyback Bonds for an aggregate minimum principal amount of US$87,000,000 (the "Buyback Offer") at an offered price of 103.00 per cent of the nominal amount of the Bonds (plus accrued interest on the repurchased amount).

The Buyback Offer will be funded by a portion of the aggregate net cash proceeds CMMC expects to receive from the gross US$170,000,000 cash consideration payable by Harmony on completion of the Transaction.  The Company is relying on anticipated cash flows generated from the Copper Mountain Mine and the net cash proceeds from the Transaction to meet its future cash commitments.

In addition, 100% of the net cash proceeds from any future contingent consideration received by the Company from Harmony pursuant to the Transaction before the maturity date of the Bonds on April 9, 2026 will be applied to either: (i) make further offers to buyback Bonds at an offered price of 103.00 per cent of the nominal amount of the Bonds (plus accrued interest on the repurchased amount) if such contingent consideration is received prior to the applicable interest payment date in April 2024; or (ii) redeem Bonds in accordance with the call terms of the Bonds if such contingent consideration is received on or after the applicable interest payment date in April 2024.

Copper Mountain's flagship asset is the 75% owned Copper Mountain Mine located in southern British Columbia near the town of Princeton. The Copper Mountain Mine currently produces approximately 100 million pounds of copper equivalent per year, with expected annual average production to increase to approximately 140 million pounds of copper equivalent.  Copper Mountain trades on the Toronto Stock Exchange under the symbol "CMMC" and Australian Stock Exchange under the symbol "C6C".
