Free Money’ in Copper? Coda Minerals’ Tech Revolutionizes Copper Recovery Rates

The clean energy revolution is sparking unprecedented demand for copper, a critical metal in electric vehicles, renewable energy systems, and electrical infrastructure. However, traditional copper mining and extraction methods are struggling to keep pace, often leaving significant amounts of copper unrecovered and creating environmental concerns. But what if there was a way to unlock “free money” from existing copper resources?

Coda Minerals (ASX: COD) is making waves in the copper industry with a technological breakthrough that promises to revolutionize copper recovery rates. Their innovative approach could not only boost copper production but also transform the economics of copper mining, potentially unlocking substantial value for investors and contributing to a more sustainable future.

The Looming Copper Crisis: A Supply-Demand Imbalance

Copper is essential for modern life, serving as a highly efficient conductor in countless applications. As the world transitions to clean energy, the demand for copper is expected to skyrocket. The International Energy Agency (IEA) estimates that clean energy technologies could more than double copper demand by 2040 compared to 2023 levels. This surge in demand is driven by the increasing adoption of electric vehicles, the expansion of renewable energy infrastructure, and the modernization of electrical grids.

However, copper supply is struggling to keep up. Declining ore grades, complex mineralogy, and the environmental challenges associated with traditional mining methods are hindering copper production. The IEA predicts a potential 30% shortfall in copper supplies by 2035 if significant action isn’t taken. This looming supply-demand imbalance is driving copper prices upward, creating both challenges and opportunities for the copper industry.

Coda Minerals’ Technological Leap: Unlocking “Free Money”

Coda Minerals, an Australian company focused on copper exploration and development, has achieved a significant breakthrough with its Elizabeth Creek Copper-Silver Project in South Australia. The company has developed a chloride leaching technology that dramatically increases copper recovery rates from its ore.

Traditionally, copper is extracted from sulfide ores using a process called flotation, which typically achieves recovery rates of 75-85%. Coda Minerals’ new technology, however, boasts recovery rates of up to 95% [3, 8]. This represents a quantum leap in copper extraction efficiency, allowing the company to recover significantly more copper from the same ore body.

Coda Minerals CEO Chris Stevens has characterized this advancement as creating “effectively free money,” highlighting the potential for increased revenue generation and reduced capital requirements [14, 21]. By recovering more copper from each ton of ore, the company can boost production without increasing mining activity, leading to lower operating costs and a smaller environmental footprint.

How Does It Work? Chloride Leaching Explained

Coda Minerals’ breakthrough lies in its adoption of chloride leaching technology for the entire ore body, replacing traditional flotation concentration methods [11]. This innovative approach involves grinding the ore to a coarser size than previously planned before conducting a four-hour chloride leach under controlled oxidative conditions. The solution containing dissolved copper and silver is then separated for downstream processing.

Chloride leaching is an established technology used in approximately 20% of global copper production [11]. The process leverages two key properties of high-concentration dissolved chloride ions:

The ability to form soluble metal-chloride complexes.
The promotion of oxidation in sulfide minerals with the help of oxidants.

This method offers several advantages over traditional flotation:

Higher Recovery Rates: Achieves significantly higher copper and silver recovery rates compared to flotation.
Simplified Flowsheet: Eliminates complex flotation circuits, reducing processing equipment requirements and capital costs.
Lower Energy Consumption: Operates at a coarser grind size, reducing power requirements.
Reduced Environmental Impact: Uses less water and emits fewer pollutants compared to traditional smelting methods.

Economic and Environmental Benefits

The increased recovery rates and simplified processing flowsheet translate into significant economic and environmental benefits for Coda Minerals and the broader copper industry [3, 8, 11]:

Increased Metal Production: Extracting 10-15% more recoverable copper from the same resource base.
Capital Efficiency: Reducing processing plant capital requirements by 15-25%.
Operating Cost Reduction: Decreasing production costs by $0.10-0.30 per pound.
Enhanced Project Value: Improving net present value (NPV) by 20-40% at conservative pricing.
Reduced Waste: Minimizing the volume of material subjected to intensive downstream processing.
Lower Emissions: Reducing emissions across the processing chain by 15%.
Water Conservation: Reducing water usage by up to 25%.

Implications for the Copper Industry

Coda Minerals’ technological breakthrough has far-reaching implications for the copper industry [15]:

Unlocking Low-Grade Resources: Enables the economic extraction of copper from low-grade ores and tailings, expanding the available resource base.
Extending Mine Life: Extends the life of existing mines by improving recovery rates from existing ore bodies.
Promoting Sustainable Mining: Reduces the environmental impact of copper mining by using less energy, water, and chemicals.
Meeting Growing Demand: Helps meet the growing global demand for copper driven by the clean energy transition.

Investing in the Future of Copper

Coda Minerals’ innovative technology and promising Elizabeth Creek project have attracted significant investor attention. The company’s share price has increased by 56.88% over the past year, reflecting the market’s recognition of its potential [9]. As of September 18, 2025, Coda (COD) was trading at a price of 0.14 on the Australian Stock Exchange (ASX) [5].

Analysts covering Coda Minerals have a consensus target price of AU$0.90, indicating a potential upside of over 500% from the current share price [9]. The company is currently advancing its Elizabeth Creek project through pre-feasibility studies, with a clear pathway to production by 2029 [22].

Coda Minerals’ technological breakthrough represents a significant step forward in copper extraction, offering a more efficient, sustainable, and economically viable approach to meeting the world’s growing copper demand. By unlocking “free money” from existing copper resources, Coda Minerals is positioning itself as a key player in the future of the copper industry and a valuable contributor to the clean energy transition.

The Road Ahead: Challenges and Opportunities

While Coda Minerals’ technology holds immense promise, several challenges and opportunities lie ahead:

Scaling Up Production: Successfully scaling up the chloride leaching process to commercial production levels.
Securing Funding: Securing the necessary funding to advance the Elizabeth Creek project through feasibility studies and construction.
Market Volatility: Navigating the volatility of copper prices and global economic conditions.
Collaboration and Partnerships: Forming strategic alliances with other mining companies and technology providers.
Expanding Applications: Exploring the application of chloride leaching technology to other copper deposits and mineral resources.

Conclusion

Coda Minerals’ technological revolution in copper recovery is a game-changer for the industry. By achieving unprecedented recovery rates, simplifying processing, and reducing environmental impact, Coda is unlocking “free money” from copper resources and paving the way for a more sustainable future. As the world transitions to clean energy, companies like Coda Minerals will play a critical role in meeting the growing demand for copper and ensuring a secure and sustainable supply of this essential metal.
