[{"type":"text","content":"\n \nRNS Number : 1599F Keras Resources PLC 11 July 2019 \n\nKeras Resources plc / Index: AIM / Epic: KRS / Sector: Mining\n11 July 2019\nKeras Resources plc ('Keras' or the 'Company')\nNayega Manganese Metallurgical Testwork Results\n \nKeras Resources plc, the AIM listed mineral resource company, is pleased to announce results from the metallurgical testwork on the 10,000-tonne bulk sample collected at its flagship asset, the Nayega Manganese ('Mn') Project, in northern Togo ('Nayega' or 'the Project'). Testwork undertaken included production chemical analysis to prove up the on-site beneficiation circuit, metallurgical testwork to prove the suitability of the ore in the manganese alloys industry, and leach testwork to assess whether the ore has the potential to be a source of high grade manganese in lithium-ion batteries to supply the growing Electric Vehicle ('EV') market. \n \nHighlights\n \n· Testwork assessing the potential to supply Nayega manganese to the steel industry:\no On-site processing using dry screening and wet scrubbing to produce a beneficiated ore averaged 38.88% Mn, 6.28% Fe and 11.5% SiO2\no Nayega ore is best suited to production of silico-manganese alloy\no Discussions remain ongoing with potential off-takers to provide both development funding to expand the existing 6,500 saleable tonnes per month operational infrastructure and for an off-take agreement for future ore produced at Nayega\n \n· Testwork assessing the potential to supply Nayega manganese to the battery and/or agriculture sectors:\no Sighter leaching testwork completed on samples obtained from the transitional and deeper Saprolitic zones within the Nayega orebody\no Leaching results have been encouraging with in excess of 90% recovery being achieved in less than two hours from both ore samples\no Nayega manganese is an oxide ore which leaches more favourably compared with South African carbonate ores\no Solutions produced contained minimal concentrations of impurities, indicating a reduced risk of issues in downstream processing\no Significant growth potential for manganese as a replacement for cobalt in lithium-ion batteries as producers look to secure cost competitive, responsibly mined long term raw material supply\no ...
