Dundee Sustainable Technologies Inc. To Process High Grade Gold Concentrate
Toronto, Ontario May 8, 2014 – Dundee Corporation is pleased to announce that its 86% controlled subsidiary, Dundee Sustainable Technologies Inc. (the “Company” or “DSTI”) listed on the CSE (CSE: DST) and the developer and owner of proprietary technologies to serve the natural resource sector with environmentally friendly procedures, is pleased to provide further information on its progress to date.
The Company has arranged a contract to process a High Grade Concentrate.
After significant testing of both ore and concentrate received in November 2013 from a privately held gold mining company, DSTI has entered into an arrangement to process their materials once the demonstration plant becomes operational in mid-January 2015. Pursuant to this arrangement DSTI 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 DSTI, over a 12 month period, to begin after the demonstration phase of the DSTI plant in Quebec is completed.
To date, DSTI has obtained 25 patents in 19 countries for its technologies relating to the extraction of precious metals and base metals, as well as the neutralization of arsenic and production of fertilizer. DSTI has 14 pending patent applications worldwide for its technologies, which include the ability to process gold concentrates without the use of cyanide.
The samples of concentrate and ore furnished to DSTI for testing in November 2013 were composed of gold, silver, copper, lead and zinc.
Initial testing on the concentrate achieved gold recoveries in excess of 97%, despite the presence of substantial base metals in the concentrate. For the successful processing, DSTI 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.
