MONTREAL, QUEBEC, September 11, 2014 \u2013 Dundee Sustainable Technologies Inc. (\u201cDST\u201d or the \u201cCorporation\u201d) (CSE: DST), the developer and owner of proprietary technologies to serve the natural resource sector with environmentally friendly procedures, is pleased to announce successful piloting results and a 96.1% gold recovery on high grade concentrate.<\/p>\n

In May of 2014, DST received two concentrate samples totalling 1,300 kilograms from a privately held gold mining company. The samples were processed at DST\u2019s Thetford Mines facility using its patented cyanide and mercury free gold extraction process.<\/p>\n

A two (2) hour contact time, using DST\u2019s chlorination process, was necessary to achieve a gold extraction yield of 96.1%<\/strong> in the reactor, despite the presence of substantial base metals in the concentrate. The gold was recovered on silica with an efficiency of 99%. The gold loaded silica was melted to produce the gold bullion.<\/p>\n

DST has entered into an arrangement to process material once the demonstration plant becomes operational in mid-January 2015. Pursuant to this arrangement DST may at its option process up to 15 tonnes of their produced concentrate per day, provided such concentrate contains a minimum of 10 ounces of gold per tonne. As a result, up to 4,500 tonnes of concentrate (current values of +$15,000 per tonne) may be processed by DST, over a 12 month period, during which DST will receive a 50% interest in the net profits arising from the sales of the end products, net of mining, concentration, processing and transportation costs and expenses.<\/p>\n

Subsequently and providing that both parties are satisfied with the results of the processing, the parties can discuss the feasibility of implementing a DST designed cyanide and mercury free extraction plant on the property on terms to be negotiated by the parties.<\/p>\n","protected":false},"featured_media":0,"menu_order":654600,"template":"","class_list":["post-39508","news","type-news","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/dundeetechnologies.com\/fr\/wp-json\/wp\/v2\/news\/39508","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/dundeetechnologies.com\/fr\/wp-json\/wp\/v2\/news"}],"about":[{"href":"https:\/\/dundeetechnologies.com\/fr\/wp-json\/wp\/v2\/types\/news"}],"wp:attachment":[{"href":"https:\/\/dundeetechnologies.com\/fr\/wp-json\/wp\/v2\/media?parent=39508"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
