Tailing Recycling Cooperation between Mistango River and United Commodity

09/17/12 - Kirkland Lake/Cobalt - Canadian Mining Company Mistango River Recources Inc. and Swiss Based United Commodity AG announced today that they plan to work together in an unified effort to advance tailing recycling. The announcement reflects the companies' commitments to work together in environmentally responsible operations and responds to the increasing effort in economically and ecological tailing management.

Mistango will provide the tailing at its premises in Kirkland Lake together with an exclusive tailing recycling right to United Commodity and United Commodity is bringing in its unique United Commodity Tailing Recycling Process (UC-RPM(R)) at Mistango's mining property.

Both parties agreed on a profit sharing (revenue minus processing costs) sharing model.

<< For Mistango we see the benefit to get a cash compensation of our so far called <<non assets tailings>>. The compensation is linked to the gold price, the grade and the processed feed quantity>>, said Robert J. Kasner, Chairman & Chief Executive Officer of Mistango.

Reto Hartmann, Chairman and CEO of United Commodity said << United Commodity will get all extracted noble metals out of its UC-RPM(R) with which we are able to process up to 150 tons of feed (ore, tailings, concentrate, slag etc.) per day at Mistango and we will have a first operation in an environment which could contribute to the environmental recovery of contaminated tailings.>>

Both parties further agreed on an option to establish a longterm partnership to develop other UC-RPM(R)applications in the mining industry of Canada.
