Tri Origin’s Field Program Returns Encouraging Results At South Abitibi Gold & Base Metal Property

August 16, 2017

Aurora, Ontario- Tri Origin Exploration Ltd (TSX-V:TOE) (“Tri Origin” or the “Company”) is pleased to announce that reconnaissance geological mapping and sampling has been completed at a portion of the Company’s large property holding along the south margin of the Abitibi Greenstone Belt in the Cobalt-Temagami region of Ontario. This work is conducted on behalf of a 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”).

Geological mapping, prospecting and sampling was conducted throughout Target Area 2 (“TA-2”), the second regional area to be investigated by the Alliance. Rock sampling verified historic gold showings and mineral occurrences and identified new occurrences which warrant further work. Results for 177 grab samples of both Proterozoic sedimentary and Archean volcanic rock assayed for gold by Tri Origin have been received to date. Of these 11 were greater than 100 ppb and 2 of these were greater than 1,000 ppb with a best result of 2,504 ppb (2.5 grams of gold per tonne). Ninety two of the 177 samples were also analysed for a variety of base metals and trace elements. Of the 92 samples, copper values were over 100 ppm in 37 samples and 10 of these were over 1,000 ppm with a highest value of 9,493 ppm (0.95%). Nickel was greater than 100 ppm in 28 samples and 7 of these were greater than 1,000 ppm with a highest value of 6,915 ppm (0.69%). Zinc was greater than 100 ppm in 30 samples with the best result being 1,023 ppm (0.1%). Cobalt was also significantly anomalous with 15 samples returning values greater than 100 ppm and, of these, 3 were greater than 1,000 ppm with the highest value 2,465 ppm (0.25%).

TA-2 covers a 15 kilometre long trend of poorly mapped, prospective volcanic rocks of the southern Abitibi greenstone belt. Results of Tri Origin’s geological investigations indicate that Archean volcanic rocks occupy a larger area than was previously thought. Approximately 50% of this area is covered by younger sedimentary rocks of Proterozoic age. These Proterozoic rocks have only received a cursory amount of surface prospecting. More importantly, there is no evidence of previous exploration of the underlying, covered Abitibi greenstone belt.  Historic mineral occurrences located within the exposed parts of the Abitibi have not been evaluated since the 1970’s. This is, in part, due to a land caution and exploration moratorium covering much of the area for almost 30 years. Tri Origin’s prospecting uncovered new mineral occurrences and undrilled “VTEM” airborne EM anomalies were detected during a survey flown by the Alliance during 2015 and 2016. The newly identified extensions of the metalliferous Abitibi Greenstone Belt under Proterozoic cover represent high-priority target areas.

Results of mapping and prospecting conducted by Tri Origin and the abundance of mineral occurrences at TA-2 provide incentive to evaluate this regionally extensive, covered terrain. The Alliance is currently evaluating recommendations for the next phase of work at TA-2. It is anticipated that the next phase of this program will consist of geophysical surveying to delineate and prioritize anomalies for diamond drilling. Shareholders will be informed of the plans for follow-up geophysical surveying and commencement of the program on approval by the Alliance management committee.

Sumac is funding Alliance activities to a maximum total expenditure of C$4.5 million. The current field work was the first part of a 2017 work program that has a pre-drilling budget of $424,000.

Alliance activities within the southern Abitibi Greenstone Belt provide a fully-funded opportunity for Tri Origin to capitalize on its strategy of identifying and acquiring prospective, district-scale properties in well-mineralized mining areas and advancing these properties toward making new discoveries.

Tri Origin is pleased to participate with Sumac in its mineral exploration efforts and values Sumac’s contributions to this Alliance. Sumitomo, Sumac’s parent company, is a Japanese firm engaged in gold and base metals mining, smelting and refining, manufacturing of semiconductor and advanced materials and other business.
