Warintza Project: Pre-feasibility Study and Maiden Reserve Highlights

Solaris Resources has published a pre-feasibility study (PFS) and maiden reserve for its Warintza copper project in Ecuador. This comes at a time of strong copper prices (approximately $5 USD per pound) and a looming supply deficit.

Key Project Metrics from the PFS:

Average Annual Copper Equivalent Production: 240,000 tons per year for the first 15 years.
C1 Cash Cost: $1.70 per pound.
All-in Sustaining Cash Cost (ASCC): $0.70 per pound.
After-Tax Net Present Value (NPV): $4.6 billion.
Internal Rate of Return (IRR): 26%.
Initial Capital Investment: $3.7 billion.
Resource Size: 5.8 billion tons.
Life of Mine (LOM): Over 50 years.

Matthew Rollinsson, President and CEO of Solaris Resources, expressed satisfaction with the results, stating that they reveal the "size, scale, uniqueness of this multi-generational asset." He highlighted the project's "tier one" and "quartile one" status in terms of cash costs and operational simplicity.

Project Characteristics and Advantages

The Warintza project boasts several characteristics that make it highly attractive to major mining companies:

Near-Surface Ore Body: The ore body is located very close to the surface, significantly reducing pre-stripping costs and making it easier to access.
Operational Simplicity: It is a large-scale open-pit mine with conventional mining and processing methods, which are well-understood and less complex.
Low Strip Ratio: The strip ratio profile is 0.53 to 1, which is significantly lower than the median average of around 2.5 to 1 for large porphyry deposits globally. This means less waste removal is required.
Strip-Adjusted Grade: When considering the strip ratio, the grade of the ore body is pushed to the top end of global quartile one charts.
Homogeneous Ore Body: The deposit is very homogeneous, providing flexibility in mine planning over its 50-year life.
Excellent Infrastructure: Ecuador offers good infrastructure, including road access and ports, which facilitates project development and operation.
Longevity: The over 50-year mine life is a rare and highly desirable attribute in the copper sector.

Rollinsson emphasized that the PFS is the first time the market can fully grasp the "size and uniqueness" of the deposit, calling its tier-one attractiveness "phenomenal."

Comparison with Other Copper Projects

Rollinsson, drawing on his experience at major mining companies, noted that the near-surface nature and long mine life of Warintza are key factors that large mining companies seek. He contrasted Warintza with other large copper development projects, such as one in northern Ecuador and those in the Vicuña district of Argentina, which are described as "quite deep." This depth increases capital costs and complexity. Therefore, Warintza is positioned as a highly competitive option for future copper development.

Phased Permitting and Expansion Potential

The Warintza project will be permitted in two phases:

Phase One: Covers a 22-year mine life, primarily due to the current capacity of the tailings dam (1.3 billion tons).
Expansion Potential: Solaris has identified approximately 10 different locations for future tailings deposition, which could extend the mine life by an additional 30 years, servicing the full 5.8 billion-ton resource. This expansion is not currently included in the Environmental Impact Assessment (EIA) for Phase One.

Corporate Developments and Strategy

Solaris Resources has undergone significant corporate changes:

Listing on NYSE American: The company listed on the NYSE American Exchange.
Redomicile to Switzerland: The company redomiciled to Switzerland following the Canadian government's decision not to allow a $130 million investment from China's Zijin Mining. Rollinsson stated that the Zijin transaction was from a "different phase of the company's life" and involved a minority investment.
New Leadership and Strategy: A new team and strategy were implemented in January, focusing on de-risking the project, accreting value through milestones, and exploring greenfield opportunities. The market has responded positively to this clear strategy.
Early Works Program and Financing: The company commenced an early works program at Warintza about a year ago and secured a $200 million financing from Royal Gold.

Maximizing Shareholder Value and Optionality

Rollinsson clarified Solaris's current objective: "maximization of value for shareholders and retention of optionality." While the company has a direct strategy to execute the project, they remain "receptive to having conversations" regarding potential transactions, acknowledging that Warintza is a large project requiring significant capital.

Context of Copper M&A: The discussion touched upon the active copper M&A landscape, including the $53 billion merger between Anglo-American and BHP, and Core Mining's bid for New Gold. Rollinsson believes that consolidation should create growth and be explainable to shareholders.

Copper Market Dynamics and Outlook

Rollinsson provided insights into the copper market:

Supply Deficit: The market is characterized by a significant and growing supply-demand imbalance. The current minable tons are around 24 million tons per year, with an annual growth requirement of 600,000 to 1 million tons, which is not being met by new supply.
Supply Disruptions: Recent disruptions at major underground mines (El Teniente, Grasberg, and Kamoa) have created short-term distortions in supply.
Growing Demand: Demand for copper is being driven by several factors:
- EV Revolution: The transition to electric vehicles.
- Decarbonization: The global effort to reduce carbon emissions, requiring copper for renewable energy infrastructure.
- AI Demand: Emerging demand from artificial intelligence infrastructure.
- Infrastructure Development: Countries like India are experiencing significant growth in infrastructure development, leading to increased copper consumption (India is consuming 1.5 million tons per year with a 15% CAGR).
Pricing Environment: The current pricing environment is becoming "very interesting" for new projects to be built.
US Trade Investigation: The Section 232 trade investigation in the US, resulting in tariffs on copper, is seen as a reflection of the criticality of copper as a supply chain component for countries. This dynamic is expected to continue globally as nations recognize copper's importance for decarbonization efforts.

Ecuador's Mining Environment and Exploration Tax

The re-election of President Daniel Noboa in Ecuador is viewed positively for mining development. However, a new exploration tax has been implemented to fund the fight against criminal mining.

Impact on Solaris: Rollinsson stated that this tax is "not material" to Solaris compared to other companies.
Support for Anti-Illegal Mining Efforts: Solaris supports efforts to combat illegal mining and has voiced its opinions through the mining chamber and relevant ministries.
Ecuador's Mining Focus: Ecuador views mining as the third-largest pillar of its economy, with successful precedents and a supportive environment for the industry.

2025 and 2026 Priorities and Catalysts

Solaris Resources has a clear roadmap for the coming years:

2025 Priorities:

Long-Term Liquidity: Ensure cash flow to support the project through to a Final Investment Decision (FID) in late 2026.
PFS Publication: Completed.
Updated Mineral Resource Estimate: Following 77,000+ meters of drilling in 2024-2025.
EIA Technical Approval: Aiming for technical approval of the EIA by year-end 2025. The EIA was filed in August 2024, and the company has been actively responding to government queries. Approval is anticipated in the next few weeks.

2026 Priorities:

Exploitation Permits: Obtain all exploitation permits by the second half of 2026.
