Progress Update at Tri Origin's Gold Projects



September 12, 2018 / TheNewswire / Aurora, Ontario - Tri Origin Exploration Ltd. (TSX-V: TOE) ("Tri Origin" or the "Company") has completed summer field activities at its portfolio of gold exploration projects in Ontario. Work has included; geological mapping and sampling at its 100%-owned North Abitibi project, geochemical analyses at the Sky Lake project and diamond drilling at its 50%-owned South Abitibi project. In addition, drilling is nearing completion at the Bay Lake North cobalt property under agreement with MetalsTech Limited. Tri Origin is now planning to commence diamond drilling at the North Abitibi project.

A program of geological mapping and sampling was recently completed at the North Abitibi gold property located 150 kilometres north of Kirkland Lake and approximately 40 kilometres west of the Casa Berardi gold mine in Quebec. This work was conducted at a large area of the Road Gold Zone which was exposed by trenching previously completed by Tri Origin. Mapping distinguished two contiguous and overlapping styles of gold mineralization. The first is laterally continuous, iron-carbonate altered and pyritic tuff and the second is discontinuous, cross-cutting quartz-sulphide veins. This work was successful in tying the surface location of gold mineralization to induced polarization survey results and added confidence in targeting proposed drill holes.

A diamond drilling program is now being planned at North Abitibi and is anticipated to commence later in September. The program is intended to be a preliminary investigation of deeper targets delineated below both the Spade Lake and Road Gold Zones. The Spade Lake Zone has been traced by drilling for over 3 kilometres in strike length but has only been drilled to depths between 100 and 200 metres below surface. Similarly, the Road Gold Zone was previously known to extend for at least 300 metres in length from 3 historic diamond drill holes. Excavating and sampling by Tri Origin has extended the known limits of gold mineralization to 600 metres in length however, it has also only been drilled to approximately 100 metres in depth. Both zones are open.

At the Company's Sky Lake project near the Pickle Lake Gold District in northwest Ontario a property-wide program of major and trace element geochemistry was commenced following field activities completed last year. Sky Lake hosts a variety of partially delineated, historic gold deposits and nearby occurrences which are being targeted for upcoming drilling. Of 23 grab samples recently analysed for gold and trace elements, gold values to 5056 ppb from a gossanous outcrop and 1232 and 899 ppb from historic, moss-covered trenches were returned. Other grab samples returned values of up to 2541 ppb in arsenic which, in this environment, is considered a positive pathfinder element which may indicate nearby gold mineralization.

A program of diamond drilling was recently completed at the South Abitibi project in the Cobalt-Temagami region of Ontario. As reported in a Tri Origin news release of August 8, 2018, a newly discovered zone of gold mineralization was intersected in two holes located 400 metres apart and returned assays of up to 1.5 ppm of gold across 0.5 metres. Significant abundance of nickel and copper was also returned from samples of disseminated and semi-massive pyrrhotite with values of 0.39% nickel and 0.45% copper over narrow intervals within broader, low grade nickel-copper zones. The program was conducted on behalf of an Alliance entered into between Tri Origin and Sumitomo Metal Mining Canada Ltd. to explore for gold and base metals in the southern Abitibi Greenstone Belt. Final drill results are being reviewed by Sumitomo for consideration of future programs.

Furthermore, MetalsTech Limited is now completing a program of diamond drilling at the Company's Bay North Cobalt property, located 10 kilometres west of Cobalt, Ontario. MetalsTech has an option to acquire ownership of the property through staged cash payments, share issuances and work commitments (Tri Origin News Releases July 26 and August 16, 2018). MetalsTech will inform Tri Origin of drill results on completion of the program. Success by MetalsTech will result in bonus share issuances to Tri Origin which will enhance the overall value of option considerations received by Tri Origin.

Shareholders will be informed of the details of the upcoming North Abitibi diamond drilling program prior to its commencement.
