Highlights
- Gold recovery rates confirmed at 85-88%, with silver at 70-75%.
- Potential for further optimization through additional test-work.
- Resource growth drilling and early-stage development studies underway.
Titan Minerals (ASX:TTM) has reaffirmed strong gold and silver recovery rates from its Dynasty Gold Project in Ecuador through extensive metallurgical test-work. The results validate previous processing outcomes, supporting the viability of near-surface oxide ores at the Cerro Verde prospect.
Promising Test-Work Results
Recent metallurgical studies demonstrated gold recoveries ranging between 85-88%, while silver recoveries reached 70-75%. These findings align with historical data from earlier open-pit mining operations at Cerro Verde, where ore was processed at the Svetlana 1 Plant in 2018-2019.
Key takeaways from the test results include:
- Strong leaching characteristics at a grind size of P80 (106µm).
- Rapid leaching kinetics, with most gold leached within 8 hours.
- Minimal gravity recoverable gold, aligning with core sample assessments.
- Low reagent consumption, requiring just 0.7kg/t of NaCN with minimal oxygen injection.
The test-work also revealed significant opportunities to optimize the process further, potentially enhancing overall recoveries.
Advancing Project Development
Titan Minerals is progressing with early-stage development studies to build upon these promising findings. The company has engaged metallurgical experts to conduct additional test-work on transitional and primary ore domains at Cerro Verde and Iguana prospects. The goal is to validate the amenability of conventional Carbon-in-Leach (CIL) processing for gold and silver extraction.
With three drill rigs operating continuously at Dynasty, resource growth remains a key focus. The Dynasty Gold Project hosts 28.8 million tonnes of ore, with an average grade of 2.08 g/t gold and 13 g/t silver, amounting to an estimated 1.9 million ounces of gold and 12 million ounces of silver. This represents nearly two-thirds of the total Dynasty Project mineral resource of 3.1 million ounces of gold and 22 million ounces of silver.
Future Outlook and Optimization Potential
Encouragingly, diagnostic leaching has shown that approximately 10% of leach tails contain free gold, presenting a clear opportunity for further recovery optimization. As the company expands its testing to include transitional and fresh ore zones, further enhancements to recoveries are expected.
With strong financial backing and a growing resource base, Titan Minerals is well-positioned to advance Dynasty towards its next phase of development. The company remains committed to maximizing the project’s potential while leveraging favorable gold and silver market conditions in 2025.
