VANCOUVER, British Columbia : Capstone Copper Corp. (TSX: CS) (ASX: CSC) announced a record-breaking financial performance for the first quarter of 2026, anchored by a surge in realized copper prices and the successful ramp-up of its Chilean operations. The company reported a record adjusted EBITDA of $329 million, a significant leap that reflects the company’s transition into a premier high-growth, low-cost copper producer.
The Q1 results, released Monday, highlight a stark turnaround from previous years as the Mantoverde Development Project (MVDP) moves into a mature production phase. Despite a slight sequential decline in consolidated production compared to the same period in 2025, the company’s ability to capture higher market prices while maintaining cost discipline has propelled its financial metrics to new heights.
Financial Performance and Net Income Swing
The $329 million adjusted EBITDA marks the sixth consecutive quarter of growth for the Vancouver-based miner. This performance was driven primarily by a realized copper price that remains robust amid a deepening global supply deficit. Net income attributable to shareholders also saw a significant swing, reaching record levels for a first quarter, following a strong full-year performance in 2025 where the company reported $315.9 million in net income.
“Our first quarter results demonstrate the immense cash-flow-generating power of our restructured portfolio,” said John MacKenzie, CEO of Capstone Copper. “With Mantoverde now operating at steady-state milling rates and the Mantoverde Optimized (MV-O) project under construction, we are effectively lowering our consolidated cost curve while increasing our exposure to what we believe is the most critical metal for the global energy transition.”
Revenue for the quarter was bolstered by high throughput at the Pinto Valley and Mantoverde mines. Although consolidated production of 47,960 tonnes was 11% lower than the 53,796 tonnes produced in Q1 2025: largely due to planned maintenance and ore sequencing at Cozamin and Pinto Valley: the margin expansion remained the focal point for analysts and investors.
| Metric (Q1 2026) | Value | Variance (YoY) |
|---|---|---|
| Consolidated Production | 47,960 tonnes | -11% |
| Adjusted EBITDA | $329.0 million | +18% |
| C1 Cash Costs (Projected) | $2.35/lb | -4% |
| Realized Copper Price | $4.82/lb | +12% |
Mantoverde and Santo Domingo: The Growth Engine
The center of Capstone’s growth strategy remains the Mantoverde-Santo Domingo district in Chile. Following the achievement of commercial production at the $870 million Mantoverde Development Project in late 2024, the company has pivoted toward the Mantoverde Optimized (MV-O) expansion.
The MV-O project, currently in the construction and tie-in phase, is expected to increase annual production to a targeted 265,000 tonnes of copper across the company’s portfolio. For the 2026 fiscal year, Capstone management has prioritized the integration of these optimized facilities, which are designed to improve metallurgical recoveries and throughput.

Simultaneously, the Santo Domingo project is nearing a critical sanctioning decision. Capstone is currently pursuing a strategic partnership arrangement to de-risk the project’s capital intensity. Santo Domingo, located just 35 kilometers from Mantoverde, represents one of the few fully permitted, large-scale copper-gold-iron projects in the world today. The integration of these two assets is expected to unlock massive synergies in infrastructure, water supply, and power.
The company’s focus on the “district approach” is further evidenced by its new exploration program in the Mantoverde-Santo Domingo corridor. Early results suggest high-grade satellite potential that could further extend the mine life and improve the feed grade for the existing processing infrastructure.
Operational Updates: Pinto Valley and Cozamin
In Arizona, the Pinto Valley mine continues to serve as the company’s cornerstone asset in North America. While production in Q1 2026 was affected by planned mill maintenance, the site remains on track to meet its annual guidance. The company is exploring a “PV4” expansion plan, which aims to extend the mine life through 2039 by utilizing advanced leaching technologies and potentially a new mill expansion.
At the Cozamin mine in Mexico, Capstone reported steady performance despite the lower production volumes seen across the group. Cozamin remains one of the highest-margin assets in the portfolio, with C1 cash costs consistently sitting in the lower quartile of the industry. The focus at Cozamin remains on brownfield exploration to replace depleted reserves and maintain its 10-year production profile.
Market Context: The 2026 Copper Outlook
Capstone’s record EBITDA comes at a time when the copper market is facing unprecedented structural challenges. As discussed in Skillings’ analysis of the 2026 copper deficit, the lack of new “greenfield” projects and declining grades at aging mines in Chile and Peru have created a supply-demand imbalance.
“The industry is not bringing on enough new supply to meet the demands of the AI-driven data center boom and the continued electrification of transport,” noted a senior market analyst. “Companies like Capstone, which have already finished their major capital-intensive build phases and are now in the ‘harvest’ phase of the cycle, are the primary beneficiaries of this pricing environment.”
Capstone’s realized copper price of $4.82 per pound in Q1 reflects this tightness. With global inventories at historically low levels, the company is well-positioned to maintain high cash flow margins even if production remains slightly below peak 2025 levels in the short term.

Strategic Priorities and Debt Reduction
A key component of the Q1 report was Capstone’s balance sheet management. With the $329 million in EBITDA, the company has accelerated its debt repayment schedule. Management indicated that it intends to bring its net debt-to-EBITDA ratio below 1.0x by the end of 2026, providing the financial flexibility needed to sanction the Santo Domingo project without significantly diluting shareholders.
The company’s disciplined approach to capital allocation was a recurring theme in the quarterly conference call. “We are not chasing growth for growth’s sake,” MacKenzie stated. “Our focus is on high-margin tonnes. The Mantoverde expansion was our proof of concept; Santo Domingo will be our cornerstone for the next decade.”
ESG and Community Engagement
Capstone also highlighted its progress on Environmental, Social, and Governance (ESG) initiatives. The Mantoverde site now operates using 100% desalinated water, a critical achievement in the water-stressed Atacama Desert. This not only de-risks the operation from a regulatory and climatic perspective but also improves the company’s social license to operate in the region.
The company is also implementing a “zero-harm” safety culture, which has resulted in a 15% reduction in total recordable injury frequency (TRIF) rates year-over-year.

Conclusion
Capstone Copper’s Q1 2026 results signal the beginning of a new era for the company. By successfully navigating the transition from a mid-tier producer to a major player with world-class assets in Chile and the United States, Capstone is capturing the full upside of the current copper bull market.
With record EBITDA, a clear path to debt reduction, and a pipeline of organic growth projects like Santo Domingo and PV4, Capstone remains a focal point for investors seeking high-leverage exposure to the copper sector. As the global economy continues its shift toward a low-carbon future, the company’s strategic “district” focus in Chile appears increasingly prescient.
