Capstone Copper Corp. (“Capstone” or the “Company”) (TSX:CS) (ASX:CSC) is pleased to announce that first saleable copper concentrate was produced at its Mantoverde Development Project (“MVDP”) in Chile, as the mine advances commissioning and ramps up to full production levels.

The unchanged key commissioning milestones at the MVDP include:

• First ore to the primary crusher – completed in Q4 2023
• First ore to the grinding circuit – completed in Q1 2024
• First saleable concentrate – completed in Q2 2024
• Achievement of nameplate operating rates – expected during Q3 2024

“First saleable copper concentrate production at MVDP is a significant milestone for Capstone. This achievement is a testament to our dedicated and skilled teams, who continue to work towards a safe and efficient ramp-up to nameplate operating rates. MVDP remains on track and on budget with our guidance previously disclosed,” John MacKenzie, Capstone’s Chief Executive Officer, commented. “In July, we plan to release an updated feasibility study for our Santo Domingo project, followed by a feasibility study for our Mantoverde Optimized project later in the quarter, which will define the next phases of our value-accretive production growth in the district.”

About MVDP

MVDP is expected to enable the mine to process 236 million tonnes of copper sulphide reserves (which represent approximately 20% of total sulphide resources) over a 20-year expected mine life, in addition to existing oxide reserves. The MVDP involves the addition of a sulphide concentrator (nominal 32,000 ore tonnes per day) and tailings storage facility, and the expansion of the existing desalination plant and other minor infrastructure.
