The landscape of Ecuadorian mining reached a significant milestone this week as Salazar Resources (TSX-V: SRL) and its partner Silvercorp Metals Inc. released an updated technical report for the Curipamba-El Domo copper-gold project. The findings represent a substantial valuation leap, with the project’s after-tax Net Present Value (NPV) at an 8% discount rate surging 121% to US$573 million compared to the 2021 feasibility study.
This valuation jump comes at a critical juncture for both the company and the host nation. As global demand for energy transition metals intensifies, the Curipamba-El Domo project is emerging as a high-margin, low-cost asset that could redefine Ecuador’s role in the global copper supply chain. With first commercial concentrate production now slated for mid-2027, the project is rapidly transitioning from a high-potential exploration play to a fully funded construction-stage asset.
Technical Drivers: Grades, Reserves, and Longevity
The primary engine behind the 121% valuation increase is a significant expansion of the project’s mineral resources and reserves. According to the NI 43-101 technical report prepared by SRK Consulting, the Curipamba-El Domo deposit has shown remarkable geological resilience and growth.
The updated report highlights a 27% increase in Measured and Indicated (M+I) Mineral Resources, now totaling 11.4 million tonnes. More strikingly, Inferred Mineral Resources saw a 245% explosion, jumping from 1.1 million tonnes to 3.8 million tonnes. This growth is not merely a matter of tonnage; the average grades remain highly competitive at 1.85% copper and 2.11 g/t gold, complemented by significant zinc, silver, and lead credits.
For investors tracking mining stocks to watch 2026, the expansion of Proven and Probable Mineral Reserves to 7.13 million tonnes: a 10% increase: is perhaps the most vital metric. This reserve growth has directly translated into a mine life extension, now estimated at 11.5 years, up from the previous nine-year projection. In a sector where asset longevity is a key risk factor, the addition of 2.5 years of production significantly de-risks the capital investment.
Operational Efficiency and Capital Expenditure
While the valuation has soared, the project has not been immune to the inflationary pressures affecting the global mining sector. The construction budget has been revised to US$284 million, a US$44 million increase from previous estimates. However, the project remains fully funded, and the high-grade nature of the ore ensures that it remains in the lower quartile of the global cost curve.
The updated economic analysis also includes an NPV at a 5% discount rate of US$705.6 million, providing a broader look at the project's sensitivity to cost of capital. These figures are bolstered by an average Net Smelter Return (NSR) value of US$312 per tonne, set against a US$55 per tonne cut-off.
Operational planning for the site is increasingly focused on data-driven efficiency. The project operator, Silvercorp Metals, is leveraging advanced telemetry and fleet management systems to optimize the open-pit extraction phase. This focus on technology is consistent with broader AISC trends in gold mining 2026, where operators are prioritizing automation to combat rising labor and energy costs.
Ecuador’s 2026 Regulatory Pivot
The surge in Curipamba-El Domo’s value cannot be viewed in isolation from the shifting political and regulatory climate in Ecuador. For years, the country has been perceived as a high-potential but high-risk jurisdiction, hampered by a "frozen" mining cadastre and permitting bottlenecks.
However, 2026 has marked a definitive shift. In February, the National Assembly approved the Organic Law for Strengthening the Strategic Mining and Energy Sectors. This legislative overhaul is designed to "revitalize" the industry by streamlining environmental authorizations and shortening Impact Assessment (EIA) timelines from 24 months to approximately 15 months in designated "mining clusters."
Furthermore, the reopening of the mining cadastre, scheduled for late June 2026, is expected to unleash a wave of greenfield exploration capital. For Salazar Resources, which maintains a 25% carried stake in Curipamba-El Domo, these reforms provide a much more stable foundation for long-term planning. The government’s commitment to providing special security measures for strategic zones: including military presence to combat illegal mining: adds a layer of operational security that was previously absent.
Copper Price Forecast 2026: A Bullish Tailwinds
The updated technical report’s economics are significantly influenced by the broader commodity market. The copper price forecast 2026 remains overwhelmingly bullish among industry analysts. Consensus estimates now cluster between USD 10,000 and USD 12,000 per tonne, with aggressive "bull case" scenarios reaching as high as USD 15,000 per tonne.
This pricing environment is driven by a structural supply deficit that the IEA and other bodies have warned about extensively. As noted in the recent IEA mineral risk report, midstream bottlenecks and the slow pace of new mine approvals are creating a perfect storm for price appreciation. For polymetallic projects like Curipamba-El Domo, the dual exposure to copper and gold provides a natural hedge; gold has recently defended the $4,000 mark, further boosting the revenue profile of the project.
Key Risks and the Road to 2027
Despite the positive technical and economic indicators, the path to first concentrate in 2027 is not without hurdles. The project is navigating a complex social landscape. While the new mining law streamlines permits, it remains contested by environmental and Indigenous organizations. Maintaining a "social license to operate" will be as critical for Salazar and Silvercorp as the technical extraction of ore.
Additionally, Executive Decree 273 requires large-scale projects to supply 100% of their own energy needs, a response to Ecuador’s ongoing energy crisis. This adds an infrastructure layer to the project that requires substantial upfront engineering and capital.
However, the updated technical report makes one thing clear: Curipamba-El Domo is one of the most robust undeveloped polymetallic projects globally. With its 121% valuation increase, fully funded construction, and a favorable commodity cycle, it stands as a cornerstone of the next generation of copper-gold producers.
2026 Investment Outlook
For those following mining news, the Salazar-Silvercorp partnership serves as a case study in how technical optimization and favorable timing can transform project economics. As construction progresses through 2026, the focus will shift to milestone execution: specifically the arrival of major equipment and the commencement of primary earthworks.
Investors looking for mining stocks to watch 2026 will likely keep a close eye on Salazar's 25% stake, which now carries a significant implied valuation premium following this update. In a market hungry for "green copper" and high-grade gold, Curipamba-El Domo is positioned to be a standout performer.
