[{"type":"text","content":"Promising Preliminary Metallurgical Recovery at Mcquesten Gold Zone at Aurex-Mcquesten Gold Project, YukonCALGARY, AB / ACCESSWIRE / March 4, 2019 / BANYAN GOLD CORP. (\"Banyan\" or \"The Company\"), is pleased to announce the results from a series of hot cyanide (CN) shake assays completed on a suite of typical mineralization at the McQuesten Gold Zone on the Aurex-McQuesten Gold Project. These first pass recovery results returned an average recovery of 68%, indicating extraction of gold through traditional cyanide leach extraction methods is achievable within the calcareous package of the McQuesten Gold Zone within \"Block 1\" of the McQuesten Deposit.Tara Christie, Banyan Gold's President and Chief Executive Officer, commented: \"I am extremely pleased with these results, as they exceed my expectations for amenability to extraction throughout the zone of mineralization. This was the first ever metallurgical testing conducted on the McQuesten mineralized zone and has advanced our understanding of the gold mineralization at the McQuesten Gold Zone. Additional metallurgical test work, including bottles rolls will be undertaken going forward.\" Cyanide shake assays results Hot cyanide shake assays are widely used in the mining industry as a preliminary means to assess amenability of mineralization to recovery by heap leaching and to identify variations in metallurgical responses that may indicate different types or styles of mineralization that should be tested separately.In total, 222 pulverized pulp samples were selected from Banyan’s 2018 diamond drilling program, all of which had been previously assayed by fire at Bureau Veritas Labs. All selected pulps represented individual drill samples from within the McQuesten Gold Zone that reported above 0.2 gram per tonne gold in Fire Assay and were selected across all grade ranges with a broad spatial distribution throughout the zone of mineralization. These pulps were submitted for hot CN shake assays and those that assayed from 0.2 gram per tonne to 17.8 grams per tonne gold returned an average extraction of 68.2 per cent, with 90% of the samples ranging from 41.2% to 86.9%. This first pass recovery work had the objective of identifying metallurgical characteristics that would guide all future metallurgical testing. The results indicate that the gold in mineralization contai...
