[{"type":"text","content":"Roscan Gold Announces Positive Metallurgical Testing Results From the Kandiole Gold ProjectAchieved 97.6% Recoveries for Oxide and 92.9% for Fresh Mineralization Samples at Flagship Mankouke South TargetToronto, Ontario--(Newsfile Corp. - October 25, 2021) - Roscan Gold Corporation (TSXV: ROS) (FSE: 2OJ) (OTC Pink: RCGCF) (\"Roscan\" or the \"Company\") is pleased to announce results from the metallurgical test work program completed on samples from gold prospects at Mankouke South (MS1), Mankouke Center- Kandiole (KN1) and the Kabaya (KB1- KB2) within the Company's land package called Kandiole Projects located in west Mali, Africa.Highlights: All of the samples representing the deposits (Mankouke South MS1 and Center, Kandiole KN1 and Kabaya KB1-KB2) tested in this program exhibit non-refractory metallurgical features, indicating that a simple, industry-standard cyanide leach process provides excellent gold and silver extraction. Total gold recoveries by gravity, plus 48 hours of CIL on all prospects, have averaged 97% for oxide (saprolite) samples, 89% for a transition sample and 90% for fresh mineralization samples.Flagship Mankouke South achieved 97.6% in the oxide and 92.9% in fresh rock.Both Oxide and Fresh mineralization are amenable to gravity concentration to recover free gold within the milling circuit. The gravity recovery average from all samples and CIL tests is 23%.The coarse ore leach tests in two Kabaya saprolite samples, to examine heap leach amenability, provided an average of 79% recovery of gold and 93 % silver after 8 days. One sample reached 88.4% gold recovery after 72 hours.Nana Sangmuah, President and CEO, stated, \"This is a major de-risking milestone for the Kandiole project confirming simple processing flow sheet with Oxide recoveries 97% including average gravity recoveries of 23% and up to 58% in certain deposits. We are also encouraged by the potential for silver by-product credits at our relatively lower grade Kabaya deposit which should further bolster project economics.\"Table 1: CIL and Gravity Test Recovery SummaryTo view an enhanced version of Table 1, please visit:https://orders.newsfilecorp.com/files/4821/100649_table1roscan.pngTable 2: Bond Work IndexTo view an enhanced version of , please visit:https://orders.newsfilecorp.com/files/4821/100649_table2roscan.pngFurther Inform...
