Carlyle Commodities Hits 80% Gold, Silver Recovery in Newton Project Tests
Carlyle Commodities Corp (CSE:CCC, OTCQB:CCCFF) recently announced promising preliminary results from metallurgical testing on its Newton gold and silver project, highlighting a significant milestone with an approximate 80% gold extraction rate. Conducted by Base Metallurgical Laboratories, the tests are a crucial step towards conceptualizing a preliminary process flowsheet for producing gold and silver doré while evaluating the mineralization’s metallurgical performance.
Comprehensive Testing for Optimized Recovery
The metallurgical testing centered around a master composite, primarily comprising felsic volcanic material sourced from continuous drill core intervals from three drill holes. The comprehensive testwork included gravity concentration, Whole-ore-leach (WOL), and flotation at various grind sizes followed by leach of the rougher concentrate and tailings. During the initial phase, the highest recovery of gold was observed when the material was ground to a coarser size of 150 microns, recovering approximately 22.8% of the gold present in the samples at a grade of 211.8 grams per ton (g/t).
In the preliminary WOL investigation, conducted at different grind sizes, the best results in terms of gold and silver extraction were achieved with a primary grind size of P80 75 microns, extracting 73.2% of gold and 43.2% of silver. However, a follow-up 3-Stage Diagnostic leach test suggested potential gold losses due to gold being locked within sulphide minerals and gangue, indicating a need for further investigation or optimization of the extraction process.
Encouraging Results and Future Prospects
Further testing of a flotation/leach flowsheet aimed to enhance liberation and overall gold extraction yielded encouraging results. The flotation results showed 88.5% of gold and 82.6% of silver recovered to a rougher concentrate. Following regrinding and cyanide leach, the overall gold and silver extraction for the master composite stood at 80.3% and 32.7%, respectively. Carlyle CEO Morgan Good expressed optimism about these results, stating the company is “very encouraged” by the preliminary gold and silver extraction numbers and looks forward to optimizing potential recoveries. Good also mentioned the intention to test additional material from different host rocks and continue advancing the Newton project in the best interests of all stakeholders.
Implications for Carlyle Commodities and Its Stakeholders
The promising results from the preliminary metallurgical tests not only underscore the Newton project’s potential but also highlight Carlyle Commodities Corp’s commitment to optimizing its resources. As the company moves forward with further testing and optimization, the focus will remain on enhancing the project’s economic viability and ensuring sustainable development. The success of these metallurgical tests represents a significant step forward for Carlyle Commodities, potentially paving the way for increased investor confidence and heightened interest in the Newton gold and silver project.
With the metallurgical testing yielding such positive outcomes, Carlyle Commodities is well-positioned to continue its exploration and development efforts. The company’s proactive approach to addressing potential challenges, such as gold losses, demonstrates its dedication to advancing the Newton project efficiently. As Carlyle Commodities moves into the next phases of testing and optimization, the mining community and investors alike will be watching closely, anticipating further developments and the realization of the project’s full potential.
