Banyan Gold Achieves 93% Recovery in Yukon Metallurgy Tests
- Banyan Gold Corp. conducted metallurgical tests on the AurMac Project's Powerline and Airstrip Deposits, achieving gold recoveries of 93%, 92%, and 90%, respectively.
- The test program utilized conventional gravity separation and whole ore leaching methods, with significant gravity recoverable gold percentages identified.
- The results indicate strong potential for future milling operations and optimization, enhancing the economic viability of the AurMac Project.
Banyan Gold Corp. has announced significant advancements in its metallurgical test program for the AurMac Project located in the Yukon Territory. The tests focused on the Powerline and Airstrip Deposits, which together contain an inferred mineral resource estimate of 7.0 million ounces of gold. The results revealed impressive gold recoveries of 93% from Powerline, 92% from Powerline East, and 90% from Airstrip, utilizing conventional gravity separation and whole ore leaching methods at a grind size of 75 microns. The metallurgical work involved shipping representative drill core samples to Forte Analytical in Colorado for analysis. The findings indicate that the gold feed grades for the master composites were 1.05 g/t for Powerline, 0.67 g/t for Powerline East, and 1.02 g/t for Airstrip. Notably, the gravity recoverable gold percentages were 54%, 46%, and 24% for the respective deposits, suggesting a strong potential for a gravity circuit in future milling operations. Environmental assessments conducted on the samples confirmed that the deposits are not acid-generating and possess excess buffering capacity, indicating a favorable environmental profile. The results of this metallurgical test program build on previous work and are expected to enhance the economic viability of the AurMac Project. Banyan Gold's President and CEO, Tara Christie, expressed optimism regarding the potential for further optimization of gold recoveries, which could lead to improved overall performance in future economic studies. The company continues to explore the opportunities presented by these promising metallurgical results.
