Tri Origin Stakes Properties on Behalf of Abitibi Gold & Base Metal Exploration Alliance

AURORA, ONTARIO--(Marketwired - Sept. 23, 2015) - Tri Origin Exploration Ltd (TSX VENTURE:TOE) ("Tri Origin" or the "Company") is pleased to announce that it has staked a large property holding along the south margin of the Abitibi Greenstone Belt in Ontario. These properties were staked on behalf of a new gold and base metal exploration Alliance entered into between Tri Origin and Sumac Mines Ltd. ("Sumac") a subsidiary of Sumitomo Metal Mining Co. Ltd. ("Sumitomo") which was announced by Tri Origin on May 28, 2015. Sumac is funding the acquisition and initial phases of work at these properties to a maximum total expenditure of C$4.5 million. Property acquisition funded by Sumac is part of an initial two year exploration budget of C$1.5 million. Equity interest in the staked claims is held 50% by Sumac and 50% by Tri Origin.

In total the properties consist of over 1900 claim units comprising 146 staked claims which extend along a selected geological terrain of almost 70 kilometres in length. The properties cover four separate target areas identified by Tri Origin in the Cobalt-Temagami region which are interpreted to host a prospective sequence of Archean-age volcanic rocks which represent the virtually unexplored and, to date, largely unrecognized extension of the southern margin of the Abitibi Greenstone Belt. These rocks are covered by a sequence of younger, Proterozoic-age sedimentary rocks which precluded historic prospecting along this portion of the Abitibi and limited the effectiveness of earlier geophysical equipment which had minimal depth penetration ability. Furthermore, much of this terrain was excluded from exploration during the time period between 1970 and 2000 due to land cautions and exploration moratoriums. Recently released government data indicates that these covered rocks are of similar age and composition to those hosting the major gold and base metal deposits of the Bousquet/LaRonde and Noranda Mining Districts to the northeast in Quebec.

Tri Origin's research and compilation work resulted in the selection of properties where management believes that the prospective, covered Archean rocks can be effectively explored using modern geophysical techniques and drilling. As part of initial programs conducted by the Alliance, Tri Origin's field crews have completed reconnaissance geological surveys at the properties and this work has confirmed the Company's earlier interpretations.
