Business Segments
Capstone Copper organizes its business primarily around its producing mining assets and development projects. These segments represent distinct geographical and operational units that contribute to the company’s total production and revenue.
1. Mantoverde Mine
- Location: Atacama Region, Chile
- Ownership: 69.99% owned by Capstone Copper, 30% owned by Mitsubishi Materials Corporation
- Operational Scope: Open-pit copper-gold mine producing copper concentrates and copper cathodes.

Products and Services
Capstone Copper’s primary business is the production and sale of mineral commodities. The company’s diverse asset base allows for the production of multiple metals, providing exposure to various commodity markets.
1. Copper (Concentrate and Cathode)
- Revenue (2024): $1,620.5 million
- % of Total Gross Revenue: 96.16%
- Profile: Copper is the company’s core product. It is produced in two forms: copper concentrate and copper cathode.
- Copper Concentrate: Produced at Pinto Valley, Mantos Blancos, Mantoverde, and Cozamin. This intermediate product is a powder containing sulphides of copper and iron, which is sold to smelters for further processing into refined copper. The concentrate produced at Pinto Valley and Mantoverde is exported to Asia and Europe, while Cozamin’s concentrate is sold to trading companies in Manzanillo, Mexico. Mantos Blancos concentrate is delivered to a local smelter.
- Copper Cathode: Produced at Pinto Valley, Mantos Blancos, and Mantoverde via SX-EW technology. These are high-purity copper sheets (99.99% pure) produced from oxide ores and low-grade material. Cathodes are sold directly to end-users or traders.
2. Silver
- Revenue (2024): $40.2 million
- % of Total Gross Revenue: 2.39%
- Profile: Silver is a significant by-product, primarily from the Cozamin Mine and Mantos Blancos Mine. At Cozamin, silver is highly correlated with copper mineralization and recovered in the copper concentrate. Capstone has a silver stream agreement with Wheaton Precious Metals for a portion of the silver production from Cozamin. Mantos Blancos also recovers silver credits in its concentrate.
3. Gold
- Revenue (2024): $22.5 million
- % of Total Gross Revenue: 1.33%
- Profile: Gold is recovered as a by-product, primarily from the Mantoverde Mine and Pinto Valley Mine. At Mantoverde, gold is contained within the copper concentrate produced from the new sulphide plant. Future production from the Santo Domingo project will also include significant gold credits.
4. Molybdenum
- Revenue (2024): $2.0 million
- % of Total Gross Revenue: 0.12%
- Profile: Molybdenum is produced as a by-product concentrate at the Pinto Valley Mine. It is separated from the bulk copper concentrate via a dedicated flotation circuit. Molybdenum is used primarily in steel alloys.
5. Zinc
- Revenue (2024): $0.0 million (Produced 224,000 lbs in 2024)
- % of Total Gross Revenue: 0.00% (Revenue was nominal or not recognized separately in the summary table, historically a revenue source).

6. Iron (Future)
- Revenue (2024): $0.0 million
- % of Total Gross Revenue: 0.00%
- Profile: Iron is a key future product from the Santo Domingo Project. The project is designed to produce a high-grade magnetite iron concentrate as a co-product of copper production, utilizing magnetic separation to recover iron from copper tailings.
7. Cobalt (Future)
- Revenue (2024): $0.0 million
- % of Total Gross Revenue: 0.00%
- Profile: Cobalt is a strategic future opportunity for the Mantoverde-Santo Domingo district. The company is evaluating the recovery of battery-grade cobalt from pyrite concentrates found in the district’s ores.

Future Strategy
Capstone Copper’s strategy is defined by a clear pathway to transformational growth, aiming to create a leading copper district in Chile.
- Mantoverde-Santo Domingo District Integration: The core strategic vision. The company aims to integrate the expanded Mantoverde mine with the Santo Domingo project to create a district producing over 200,000 tonnes of copper annually. This involves shared infrastructure (desalination, power, pipelines) and operational synergies.
- Mantoverde Optimized: Executing the debottlenecking project to maximize the value of the installed sulphide plant, increasing capacity to 16.4 million tonnes per annum.
- Cobalt Production: Realizing the value of cobalt resources in the district to produce battery-grade cobalt sulphate, creating a diversified green energy metals producer.
- Brownfield Growth: Pursuing “phase II” expansions at Mantos Blancos and extending mine life at Pinto Valley and Cozamin through exploration.
- Sustainability: Achieving Copper Mark assurance at all operations and adhering to the Global Industry Standard on Tailings Management (GISTM).
Key Strengths
- Massive Resource Base: Total Measured and Indicated Resources at Pinto Valley alone exceed 1.3 billion tonnes. Mantoverde Sulphide Resources exceed 500 million tonnes.
- Growth Pipeline: A defined path to significantly higher production volumes through Mantoverde Optimized and Santo Domingo.
- Operational Diversification: Four producing mines reduce asset-specific risk.
- Cost Position: New production from Mantoverde is lower on the cost curve, driving down consolidated cash costs.
- Fully Permitted Projects: Santo Domingo is fully permitted for construction, a significant advantage in the current regulatory environment.
- Strategic Partnerships: Strong relationship with Mitsubishi Materials Corporation (30% partner at Mantoverde).
Key Challenges and Risks
- Commodity Price Volatility: Revenue is highly sensitive to copper prices. A decline in prices would directly impact profitability and the viability of development projects.
- Geotechnical & Hydrological Risks: Operations face inherent risks such as pit wall failures or tailings dam instability. Pinto Valley has deep pits and aging tailings facilities; Chilean assets are in seismically active zones.
- Water Availability: Operations in Chile and Arizona are in water-scarce regions. While Mantoverde uses desalination, Pinto Valley relies on a water supply agreement with BHP Copper that expires in 2030.
- Project Execution: Risks associated with construction delays, cost overruns, and commissioning challenges for MV Optimized and Santo Domingo.
- Political & Regulatory Uncertainty: Operating in Chile and Mexico involves exposure to changing tax regimes (e.g., Chilean mining royalty tax), labor laws, and permitting processes.
- Cybersecurity: Reliance on IT systems makes the company vulnerable to cyber-attacks, including potential threats amplified by AI technologies.
- Social License: Community opposition or blockades (potential in Mexico and Chile) could disrupt operations.
Conclusion and Strategic Outlook
Capstone Copper Corp. has positioned itself as a high-growth copper producer with a distinct advantage in its asset quality and jurisdiction profile. 2024 was a pivotal year, marked by the successful commissioning of the Mantoverde sulphide plant, which has transformed the company’s production profile.
Looking ahead, Capstone is on a trajectory to become a leading premier copper miner. The immediate focus is on ramping up Mantoverde to full nameplate capacity and advancing the Mantoverde Optimized project. The longer-term value driver lies in the unlocking of the Santo Domingo project and the realization of the district integration strategy in Chile. With a strong balance sheet reinforced by recent refinancing, a refreshed leadership team, and a portfolio of long-life assets, Capstone Copper is strategically equipped to capitalize on the global structural deficit in copper supply.
