How is Gualcamayo Gold Mine Transforming Under New Ownership?
From Closure to Renaissance
The Gualcamayo gold mine has experienced a remarkable turnaround since changing hands in 2023. When Minas Argentinas (part of Aisa Group) acquired the operation, it was on the verge of closure—a common fate for aging mines with depleting high-grade ore reserves.
Today, the mine produces approximately 50,000-55,000 ounces of gold annually through secondary recovery methods. This represents an interim production strategy while the company develops its ambitious expansion plans.
Current Operations and Production
The existing operation employs innovative secondary recovery techniques to extract remaining gold from previously processed materials. This approach has allowed the mine to maintain production while planning for its substantial transformation.
Key aspects of current operations include:
- Annual production: 50,000-55,000 ounces of gold
- Processing method: Secondary recovery techniques
- Workforce: Significant local employment
- Operational footprint: Utilizing existing infrastructure
What Does the $665M Investment Plan Include?
Strategic Recalibration
Initially, Minas Argentinas proposed a $1 billion (1.29 trillion pesos) investment for Gualcamayo. However, following discussions with government officials, the company adjusted its plan to $665 million to better align with RIGI requirements while maintaining project viability.
This recalibration demonstrates the company's commitment to working within Argentina's regulatory framework while pursuing significant expansion.
The Carbonatos Profundos Project
The centerpiece of the investment is the development of the Carbonatos Profundos mine—a new underground operation situated beneath the existing mine. This project represents a fundamental shift in mining approach, targeting gold production from sulphide deposits rather than oxide ores.
Key components of the new mine include:
- Underground development beneath existing operations
- Focus on sulphide ore extraction
- Projected annual production: 120,000 ounces of gold from 2029
- Estimated operational lifespan: 17 years
- Potential export value: $400 million annually
Advanced Processing Infrastructure
A significant portion of the investment will fund the construction of a state-of-the-art pressure oxidation plant. This specialized facility will enable the processing of complex sulphide ores that contain gold not amenable to conventional extraction methods.
The pressure oxidation technology represents a significant advancement in metallurgical processing capabilities in Argentina, allowing for higher recovery rates from challenging ore types.
Renewable Energy Integration
In alignment with global mining investment opportunities, the investment includes the development of a 50MW solar park dedicated to powering the mining operations. This renewable energy in mining component will:
- Reduce operational carbon footprint
- Lower long-term energy costs
- Enhance energy security for the operation
- Demonstrate environmental commitment
Why is Resource Potential Critical to the Project's Success?
Proven Reserves and Exploration Upside
According to Martinez Ricardo Martinez, executive director at Minas Argentinas, the Gualcamayo property holds tremendous resource potential. The company has identified:
- 3 million ounces of economically viable gold reserves
- 5 million ounces of certified gold resources
- Exploration coverage of just 3% of the 40,000-hectare property
This indicates that the majority of the property remains unexplored, suggesting significant potential for additional discoveries that could extend the mine's life beyond current projections or increase production rates.
Development Timeline
The ambitious development schedule for Gualcamayo includes:
- Construction start: 2027 for the new mine and processing plant
- Production commencement: 2029 for the Carbonatos Profundos operation
- Full production target: 120,000 ounces of gold annually
- Project duration: 17-year estimated lifespan
How Does This Investment Impact Argentina's Mining Sector?
Revitalizing Gold Production
Argentina has experienced a decline in gold production in recent years due to aging mines and depleting high-quality ore. Despite this trend, gold remains the country's leading mining export, representing 68% of total mining exports.
The Gualcamayo expansion project comes at a critical time for the sector, potentially offsetting production declines at other operations and maintaining Argentina's position as a significant gold producer. Recent gold price analysis suggests favorable market conditions for such investments.
Broader Investment Trends
The Gualcamayo project is part of a larger wave of investments under the RIGI programme. Another notable example is Rio Tinto's $2.5 billion Rincon lithium mining project in Salta province, which received official approval in May 2025.
These major investments signal growing confidence in Argentina's mining sector, despite historical challenges related to regulatory uncertainty and economic volatility.
Economic Implications
The projected $400 million in annual exports from the expanded Gualcamayo operation would make a meaningful contribution to Argentina's foreign exchange earnings. Additionally, the project will:
- Create significant employment during construction and operation
- Generate tax revenue for local and national governments
- Support ancillary businesses in the supply chain
- Develop technical capabilities within Argentina's mining workforce
What Challenges and Opportunities Lie Ahead?
Regulatory Stability
Martinez emphasized the importance of "legal security" and stable mining regulations for the success of the Gualcamayo project. This highlights a persistent concern for mining investors in Argentina—the need for consistent regulatory frameworks that transcend political cycles.
The RIGI programme represents an attempt to address these concerns by providing greater certainty for large-scale investments. However, the long-term effectiveness of this approach will depend on continued political commitment to the programme's principles.
