[{"type":"text","content":"Significant Cobalt Recovery a Major Upgrade at the Hat Copper-Gold-Cobalt Deposit in the Golden TriangleVANCOUVER, BC / ACCESSWIRE / May 10, 2021 / Doubleview Gold Corp (\"Doubleview\", the \"Company\") (TSXV:DBG) (OTC PINK:DBLVF) (FRANKFURT:1D4) is pleased to announce excellent results from its initial metallurgical tests on materials from its 100% owned Hat Copper-Gold-Cobalt deposit, located in the Golden Triangle region of Atlin Mining District in Northwest British Columbia. The initial metallurgical extraction studies were designed to evaluate the characteristics of mineralization and the potential recoverability of component metals. In particular, attention was directed to Cobalt, an increasingly valuable and sought-after commodity that only in recent years has become a potentially important economic contributor to Hat resources.For testing purposes, a composite sample, compiled from selected drill core analytical sample pulps, was processed by crushing and grinding and then divided into two sub-samples: \"Gravity\" and \"Composite\". \"Composite\" went directly to flotation, \"Gravity\" was gravity separated to remove free gold and the samples were each subjected to the same flotation sequence to produce a high gold-copper concentrate with low cobalt and a pyrite concentrate with high cobalt. Recoveries are shown in the accompanying table:HAT Flotation Results - Indicated grades and Recoveries MetalGradeRecovery(%)Sample Gravity TailsCompositeGravity TailsCompositeHead Cu (%)0.20.21 Co(ppm)132131 Au(g/t)0.360.32 Gravity Concentrate Au(g/t)11 11 Copper Concentrate Cu (%)27148176 Co(ppm)47011601926 Au(g/t)7125464Pyrite Concentrate Cu (%)0.10.156 Co(ppm)262025304948 Au(g/t)332123Combined Concentrates Cu (%) 8682 Co(ppm) 6874 Au(g/t) 8687The initial flotation tests demonstrate that it is possible to produce a high gold, low cobalt-copper concentrate and a high cobalt, low gold pyrite concentrate. Further optimization work will aim to improve selectivity, grades and recoveries.Additional mineral samples have been submitted for QEMSCAN (\"Quantitative Evaluation of Minerals by Scanning Electron Microscopy\") to better understand the mineralization of Hat polymetallic deposit and the nature of flotation tails losses, these results will be announced in due course.Metallurgical investigations have been conducted by Sepro Mineral S...
