Aldebaran's Strategic Plans for Developing the $1.5 Billion Altar Copper Project
The Canadian mining company Aldebaran Resources is positioning itself as a significant player in Argentina's copper industry with ambitious plans to develop the Altar copper project in the country's northern region. According to country manager Javier Robeto, the company is preparing to invest approximately $1.5 billion to bring this substantial mineral resource into production.
This significant capital expenditure will be detailed in the upcoming preliminary economic assessment (PEA), scheduled for release in September 2025. The assessment will provide comprehensive insights into the project's viability, development timeline, and economic potential.
Resource Magnitude and Production Scenarios
The Altar project represents one of Argentina's most substantial copper resources, with preliminary estimates indicating approximately 32 billion pounds of copper and around 6.7 million ounces of gold. These impressive figures position the project as a potentially significant contributor to global copper supply forecast at a time when demand for the metal continues to grow due to electrification and renewable energy transitions.
Robeto has indicated that the upcoming economic assessment will present two distinct production scenarios:
- Copper concentrate production – A traditional approach involving mineral processing to create a concentrated product for export
- Copper cathode production – A more refined approach producing higher-value copper metal through additional processing
"The idea would be to conduct a trade-off analysis, looking at the pros and cons," Robeto explained when discussing the production options under consideration. Each approach presents different capital requirements, operational costs, and market opportunities that must be carefully weighed.
Technical Considerations and Development Approach
The development of such a substantial resource requires careful technical planning. While specific processing methodologies haven't been fully disclosed, the trade-off analysis will likely consider factors such as:
- Water availability and management in the arid northern region
- Power infrastructure requirements
- Environmental impact differences between production methods
- Capital efficiency and operational costs
- Market accessibility for different product types
The project's remote location in northern Argentina also presents logistical challenges that must be addressed in the development plan, including transportation infrastructure for both construction materials and eventual product export.
Argentina's RIGI Program: Critical Tax Incentives with Uncertain Timeline
Investment Incentive Framework
A significant factor in Aldebaran's development plans is Argentina's recently established Régimen de Incentivo a las Grandes Inversiones (RIGI) program. Launched in October 2024 under President Javier Milei's administration, this program offers substantial tax advantages and legal protections for investments exceeding $200 million.
The RIGI program represents Argentina's effort to attract major foreign investment in strategic sectors, including mining. Benefits include:
- Significant reduction in overall tax burden
- Access to international dispute resolution mechanisms
- Enhanced investment security through legal protections
- Fiscal stability provisions to protect against regulatory changes
Timeline Challenges and Application Window
A critical concern for Aldebaran is whether the company can deploy the required investment in time to qualify for RIGI benefits. The program:
- Accepts applications through July 2026
- May have a potential one-year extension
- Has approved only two mining projects to date, both in the lithium sector
This creates uncertainty for the Altar project's economic model. As Robeto candidly acknowledged: "It's not certain we'll make it. It's a challenge because if the RIGI is cut off, what happens next? The tax burden automatically returns to 54%."
Tax Implications and Economic Impact
The difference between qualifying for RIGI and missing the application window could substantially impact the project's financial viability. Argentina's standard tax burden of 54% for mining operations without RIGI benefits represents one of the region's higher taxation rates.
For a project with $1.5 billion in initial capital expenditure and ongoing operational costs, the tax differential could amount to hundreds of millions of dollars over the project's lifespan, potentially affecting:
- Internal rate of return
- Payback period
- Overall project economics
- Investment attractiveness compared to competing global opportunities
This timing challenge highlights the complex interplay between government policy, regulatory frameworks, and mining investment decisions.
