Diamond Drilling Commences At Tri Origin’s North Abitibi Gold Project

​

September 25, 2018

​

Aurora, Ontario- Tri Origin Exploration Ltd. (TSX-V: TOE) (“Tri Origin” or the “Company”) is pleased to announce that it has commenced a program of diamond drilling at its North Abitibi gold property located 150 kilometres north of Kirkland Lake and 40 kilometres west of the Casa Berardi Gold Mine in the Abitibi Greenstone Belt of Ontario.

​

The program will consist of approximately 2,000 metres of drilling in 6 holes targeting the Spade Lake and Road Gold Zones as well as other targets delineated by the Company.

​

The Spade Lake Zone has been traced by drilling for over 3 kilometres in strike length. It consists of a pyritic, sericite-altered felsic tuff. Historic drill core assay results (including holes previously drilled by Tri Origin) range from narrow intervals of high-grade gold to thick intervals of anomalous gold. Significant down-hole assay results as recorded in the Ontario government assessment files include; 23.4 grams of gold per tonne (“g/t”) over 1.5 metres, 6.07 g/t over 6.0 metres, 1.12 g/t over 8 metres and 0.52 g/t over 25 metres. Importantly, the majority of drilling at the Spade Lake Zone is to depths of only 100 metres below surface. The objective of Tri Origin’s preliminary drilling program is to investigate targets at 300 to 400 metres below surface.

​

The Road Gold Zone was discovered in 2 drill holes completed by Newmont Mining Corp in the 1980’s and has also been intersected in previous drilling by Tri Origin returning values of up to 17.8 g/t of gold over 1.6 metres and 1.34 g/t over 10.1 metres. The Road Zone has been partially traced by this drilling for 300 metres along strike. The Zone consists of iron-carbonate altered and pyritic tuff and quartz-sulphide vein systems. A portion of the Road Gold Zone has been excavated by Tri Origin. Grab samples of altered rock and vein material from surface exposures returned values of up to 43 g/t, 25 g/t and 21 g/t of gold. Excavating has increased the known length of this gold zone however its full extent cannot be determined without drilling due to thick overburden cover along the edges of the excavation.

​

Drill hole targeting at these zones is based primarily on results of a “deep-looking” induced polarization survey (“IP”) previously completed by Tri Origin. Results from the IP survey indicate strengthening of the IP response at depths below the level of current drilling at both zones. These results are encouraging and it is management’s belief that there is good opportunity for improvement of both thickness and grade of both of the gold zones at depth.

​

The North Abitibi property is comprised of 215 mining claim cells covering an area of approximately 53 square kilometres. It is within the Abitibi Greenstone Belt, one of the world’s most prolific metal-producing regions and along trend from 6 producing and past-producing mines in Quebec including the Casa Berardi gold mine now being operated by Hecla Mining Corporation. Exploration along the Ontario extension of this productive trend has been hindered due to thick overburden cover. During September, 2016 Detour Gold Corp announced the staking of a large claim block surrounding Tri Origin’s North Abitibi property and has recently announced the intention to conduct a 2,000 metre drilling program at its property (Detour Gold Website- exploration project page, September 2018). Detour’s program is being conducted adjacent to Tri Origin’s property and indicates a renewed interest in the gold potential of the area.

​

The current drilling program is anticipated to be completed before the end of October and final assay results are expected by mid- November. Shareholders will be informed of results when available.
