[{"type":"text","content":"Banyan Gold Reports 90% Leachable Gold and Rapid Recoveries From Metalurgical Test Work of Airstrip and Powerline Zones, Aurmac Property, YukonVANCOUVER, BC / ACCESSWIRE / May 3, 2021 / Banyan Gold Corp. (the \"Company\" or \"Banyan\") (TSXV:BYN) is pleased to provide a summary of the inaugural metallurgical bottle roll test work on its flagship AurMac Project. The test work was conducted by Forte Analytical LLC of Fort Collins, Colorado on a suite of samples collected by Banyan during the 2020 drilling programs.Highlights:Gold recoveries from this work demonstrate strong heap leach kinetics and there appears to be no correlation between sulphide content and gold recoveryBottle roll test work indicates rapid leach kinetics and favorable recoveries in the oxide and sulfide zones of the AurMac DepositsUltimate extraction recoveries for gold were generally greater than 80%, and as high as 96%Ten (10) Airstrip Zone samples achieved extraction for gold that ranged from 80% to 96% and averaged 90%Five (5) Powerline Zone samples achieved extraction for gold that ranged from 86% to 92% and averaged 89%\"We are very pleased with these metallurgical results from AurMac which have exceeded our expectations with an average recovery of 90%. The results validate the potential for an open-pit, heap leach operation, with high recoveries from oxide and sulphide ore\", said Tara Christie, President and CEO. \"Drilling is ongoing, rapidly expanding the mineralized footprint at Powerline\".Metallurgical Test WorkThe metallurgical test work for the AurMac Gold Project consisted of a series of 48-hour bottle roll tests completed by Forte Analytical LLC, a company focused on metallurgical testing and optimizing heap leach operations worldwide, on 17 representative composited samples from the 2020 drill program. These samples were split between the AurMac deposits in the following manner: Airstrip (10 samples), Powerline (5 samples), and Aurex Hill (2 samples).The samples from Airstrip returned an average gold recovery of 90% (8 of the 10 samples had a recovery greater than 90%), samples from Powerline returned an average gold recovery of 89% (3 of the 5 samples had a recovery greater than 89%) and samples from Aurex Hill achieved recoveries of 60% and 80%, respectively.Gold extraction was generally complete within the first 4-8 hours with small increa...
