HighGold Mining has announced positive metallurgical test results for the Johnson Tract polymetallic Gold Project in Southcentral Alaska in US. The Project hosts the high-grade Au-Zn-Cu-Pb-Ag JT Deposit with a 0.75moz gold equivalent (indicated resource at 10.9 g/t AuEq and a 0.13moz AuEq inferred resource at 7.1 g/t AuEq. An updated and expanded mineral resource estimation for the JT Deposit is expected to be delivered before the end of the second quarter of 2022. The polymetallic (Au-Zn-Cu-Pb-Ag) JT Deposit exhibits an excellent response using conventional metallurgical techniques. Locked cycle flotation tests yielded very high-quality copper, zinc, lead and gold concentrates produced at a coarse primary grind with very good metal recoveries, low impurities and negligible penalty elements. Highlights include: Gold recovery of 97.2% combined total of payable gold to concentrates and leaching of tailsZinc recovery of 92.3% to a concentrate grading 52.6% zincCopper recovery of 84.5% to a concentrate grading 30.6% copperLead recovery of 72.4% to a concentrate grading 62.1% leadGold pyrite concentrate grading 64.3 g/t goldCoarse primary grind size of 125 micronsHighGold is mineral exploration company focused on high-grade gold projects located in North America. HighGold’s flagship asset is the high-grade Johnson Tract Gold (Zn-Cu) Project located in Southcentral Alaska in US. The Company also controls a portfolio of quality gold projects in the greater Timmins gold camp, Ontario, Canada that includes the Munro-Croesus Gold property, which is renowned for its high-grade mineralization, and the large Golden Mile and Timmins South properties.
