Capstone Copper Announces Achievement of Commercial Production at MVDP and Outlines Leadership Succession Plan

In This Article:

VANCOUVER, British Columbia, October 01, 2024--(BUSINESS WIRE)--Capstone Copper Corp. ("Capstone" or the "Company") (TSX:CS) (ASX:CSC) today announced that the Mantoverde Development Project ("MVDP") has achieved commercial production and, following this major corporate milestone, outlines its leadership succession plan.

On September 21, 2024, the MVDP achieved commercial production defined as the achievement of reaching a minimum of 30 consecutive days of operations during which the mill operated at an average of 75% of nameplate throughput of 32,000 ore tonnes per day. Strong performance on key metrics, such as concentrate grade and recoveries, were at or above targeted levels for this point of the ramp-up while the mill feed grade has reconciled well with the mine plan model.

The Company notes that 2024 consolidated copper production is trending to the low end of the guidance range of 190,000 to 220,000 tonnes of copper, while C1 cash costs1 are trending slightly above the guidance range of US$2.30 to US$2.50 per payable pound, mainly due to the ramp-ups at Mantoverde and Mantos Blancos occurring later in the year than was expected when guidance was issued in January 2024. Given the ramp-up success at MVDP and the recent ramp-up performance at Mantos Blancos, the Company expects the fourth quarter to be the strongest quarter of the year across the portfolio.

LEADERSHIP SUCCESSION PLAN

The following leadership changes will take effect at the next Annual General Meeting of the Company on May 2, 2025:

  • John MacKenzie will transition from Chief Executive Officer and will be nominated to the role of Non-Executive Chair of the Capstone Board of Directors;

  • Cashel Meagher, current President and Chief Operating Officer, will succeed Mr. MacKenzie as CEO of Capstone, and will also be nominated as a member of the Board;

  • James Whittaker, current Senior Vice President, Head of Chile, will succeed Mr. Meagher as COO. This facilitates a flattening of the organizational structure with all mine general managers reporting directly to the COO; and

  • Darren M. Pylot, founder of Capstone Mining Corp. and current Chair of the Board, will end his term on the Board after over 20 years as a founder, CEO, and Chair of Capstone.

John MacKenzie, Capstone’s CEO, commented, "It has been a privilege to have been the Chief Executive Officer of Capstone Copper since its formation in March 2022 and I look forward to continuing to serve the Company as Board Chair. We have made significant strides since the merger: we integrated Capstone Mining and Mantos Copper to position us as a business with peer-leading growth in copper with four producing copper mines and one development project in great jurisdictions across the Americas; we successfully completed construction and achieved commercial production levels at our flagship Mantoverde Development Project; and we have strengthened our team with some of the best people in the mining industry. Now is the right time for these changes and I have every confidence in Cashel to lead the execution of our next stage of growth at Capstone, including our Mantoverde Optimized and Santo Domingo projects."
