Detour West is a gold exploration project located 180 kilometres north of Timmins, Ontario and 20 kilometres west of the Detour Lake Gold Mine. The property consists of 413 100%-owner single cell mining claims and 8 partially-owned boundary cell mining claims covering an area of approximately 104 square kilometers.
Tri Origin is targeting high-grade iron-formation related and sulphidic gold deposits within a previously unexplored and overlooked extension of the Detour Lake mine trend within the Abitibi Greenstone Belt.
The property ties directly onto mining claims held by Detour Gold Corporation the operator of the nearby Detour Lake Mine which has a 15.5 million ounce gold reserve making it one of the largest gold reserves in Canada. It also covers the same rock units as the Lower Detour discovery which is comprised of a number of high-grade gold intersections announced by Detour Gold Corp and holds the promise of becoming a new, high-grade underground gold mine. Tri Origin’s property is uniquely positioned to benefit from the growth of one of Canada’s newest gold districts.
Tri Origin has selected this region to initiate a new exploration project based on its lack of previous exploration, its close proximity to the Detour Lake Gold Mine and its location within the Abitibi greenstone belt, one of the world’s most prolific metal producing regions.
The Detour West property is less than 20 kilometres west of the Detour Lake Gold Mine within the northwestern portion of the Abitibi Greenstone Belt. It is immediately north of the Detour Mine road and main power lines to the Detour Mine. Infrastructure is readily available if required for future development. Access is provided by seasonal logging roads branching off the Detour Mine Road as well as numerous trails providing year-round ATV or snowmobile access.
Detour West covers the interpreted westward extension of the volcanic and sedimentary rocks which host both the Detour Mine and Lower Detour discovery and the extensions of the associated Sunday Lake, Massicotte, and Lower Detour deformation zones. Exploration east of the Detour Lake area in Québec has been extensive and has uncovered several important new gold and base metal discoveries. However, west of Detour Gold Corporation’s property in Ontario, exploration has been minimal and sporadic.
The lack of previous work was due to the belief that a large portion of the Canadian Shield west of the Detour mine is underlain predominately by granitic rocks and gneisses. This area is entirely covered by glacial overburden so this earlier belief was not established through factual data but came about due to lack of bedrock mapping.
The westward extension of the prospective Detour rocks was identified by Tri Origin through detailed compilation and review of all available geological and geophysical work published by government geological surveys and the private companies which had worked in the area. Preliminary diamond drilling conducted by Dome Mines Ltd during the 1980’s west of Tri Origin’s property supports Tri Origin’s conclusion that the host rocks of the Detour Lake Mine extend westward beyond the previously mapped portions of the belt. Drill logs from this program record intersections of mafic volcanic, felsic volcanic and metasedimentary gneisses. One hole indicates that ultramafic “komatiite” was intersected and one drill hole intersected semi-massive magnetite (pyrite) rock interpreted to be iron formation.
Tri Origin has completed an airborne geophysical survey and test line of induced polarization surveying to determine appropriate geophysical techniques below areas of thick overburden. Geophysical signatures from these surveys resemble those in the mine area and Tri Origin believes that the application of modern exploration technologies will result in rapid delineation of prospective drill targets. Recommended work includes overburden drilling and basal till sampling, drift prospecting, and detailed geophysical surveying to delineate targets to be tested by diamond drilling. The evidence is sufficient to justify conducting detailed and systematic exploration at a newly recognized extension to one of Canada’s important and rapidly growing gold mining districts.
Expenditures at Detour West to the end of 2018 totalled approximately $350,000.
The Sky Lake gold project is located 310 kilometres north of Thunder Bay and 35 kilometers southwest of the town of Pickle Lake in northwestern Ontario. It is comprised of 494 100% owned single cell mining claims and 20 boundary cell mining claims covering an area of approximately 128 square kilometers. In addition, the Company holds an option agreement with Barrick Gold to earn 96% interest in patent mining claims (the “Koval” claims) covering an area of 2 square kilometers. The Sky Lake property is the largest landholding in the region.
Tri Origin is targeting iron-formation related and pyritic gold deposits within the Pickle Lake greenstone belt and controls the most promising, partially delineated gold deposits in the Pickle Lake belt.
The Pickle Lake greenstone belt is an eastward extension of the Red Lake and Birch-Uchi belts which have substantial gold production and resources. The Pickle Lake belt is host to the Pickle Crow, Central Patricia, Dona Lake, Golden Patricia and other past-producing gold mines with historic production exceeding 3 million ounces, as well as the past-producing Thierry copper/nickel mine. Sky Lake is in the middle of this prolific area within a segment of the belt where historic gold occurrences and gold deposits initially delineated by drilling during the 1950’s and 1980’s remain underexplored.
Tri Origin’s management recognizes geological similarities between the gold occurrences at Sky Lake and those of the important Bousquet/LaRonde gold producing district in Quebec. These similarities indicate that new, as yet to be discovered, multi-million ounce gold deposits may occur at Sky Lake and justify continued, detailed exploration.
Sky Lake is located in proximity to the Town of Pickle Lake and has paved highway along its eastern edge and a main power line 15 kilometres northwest of the centre part of the property. Existing infrastructure provides significant advantage to future development of the property. Access is provided by float plane from nearby bases at Pickle or Savant Lake and frozen lakes provide ski-plane or snowmobile access in the winter.
The area is underlain by a west-trending assemblage of mafic and felsic volcanic rock, iron formation, sedimentary and chemical sedimentary rock. Gold deposits are within altered, pyritic, felsic volcanic rock and adjacent sedimentary units. Tri Origin is focused on delineating resources at these pyritic gold zones. A number of other gold occurrences associated with iron formation have been identified on the property. These are of a type more typical to the past producing gold mines at Pickle Lake and also warrant follow-up surveying and drilling.
The Company has completed a full review of geological, geochemical, geophysical and diamond drilling information collected from previous work programs at the property. Tri Origin’s field work has included modern, high resolution heliborne electromagnetic and magnetic surveying, collection and analysis of over 1,000 humus and 500 mineral soil samples, geological mapping, detailed grid work including Induced Polarization geophysical surveying and a preliminary 7 hole diamond drill program. This has resulted in a substantial geotechnical database comprising over 200 diamond drill holes, geochemical analyses of over 4,200 humus and mineral soil samples and results from both airborne and ground magnetic, electromagnetic and induced polarization surveying.
Three-dimensional models of the known gold deposits have been constructed to plan for upcoming drill programs. Four sub-parallel zones spaced between 25 and 50 metres apart have been identified and traced for a distance of 1.5 kilometers along strike. These are; the Red, Orange, Purple and Yellow Zones. The northern-most Red Zone contains average composited assay results from historic drilling of 3.27 grams of gold per tonne (“g/t”) across 6.6 metres true thickness, the Orange Zone 2.40 g/t across 3.6 metres, the Purple Zone 3.76 g/t across 6.0 metres and the Yellow Zone 2.70 g/t across 3.6 metres. Management’s interpretation of these results suggests that the zones may merge at depth or along strike to the east to form a more continuous, steeply-dipping gold-rich deposit.
These deposits have only been drilled to shallow depths. Although the deposits have been traced for over 1.5 kilometres in length much of this distance has only been drill tested to 50 metres in depth with maximum drill depths of 200 metres below surface at only a few areas.
Over $1.6 million has been spent on preliminary evaluation of the property to the end of 2018. Tri Origin intends to target deeper drilling to determine the economic significance of the known deposits. Other prospective gold occurrences have been identified across the property and will be sequentially evaluated and drill-tested during future programs.
North Abitibi is a gold exploration project located 150 kilometres north and northeast of the Kirkland Lake and Timmins Mining Districts, respectively, in the Abitibi Greenstone Belt of northeastern Ontario. The property consists of 187 single cell mining claims and 28 boundary cell mining claims covering an area of approximately 50 square kilometres. Tri Origin holds 100% interest in the property subject to an agreement with Vista Gold Corp whereby upon completion of exploration expenditures by Tri Origin of $2,000,000 Vista Gold has the option to earn back a 51% interest in the property.
Tri Origin is targeting a high-grade gold deposit of the pyritic lode gold type. The secondary target is a large tonnage, lower grade disseminated deposit hosted within extensive alteration zones. At North Abitibi, gold has been intersected in diamond drill holes over a 7 kilometre long, highly-prospective trend and detailed drilling has outlined two zones which are open along strike and at depth. Gold occurs within laterally continuous units of pyritic, quartz-sericite schists, iron-carbonate altered rocks and quartz-sulphide veins. Continuity of gold mineralization and the abundance of ore-grade assays indicate that these rocks have the potential to host multi-million ounce gold deposits.
Further east, in Quebec, this segment of the Abitibi Greenstone Belt hosts the Mattagami, Selbaie, Joutel and Casa Berardi mining camps. North Abitibi is along trend and 40 kilometres from the operating Casa Berardi gold mine. Five other past-producing mines occur along the Casa Berardi trend in Quebec. Extensive overburden cover in Ontario has hindered previous exploration. However, the abundance of gold at North Abitibi and gold production along this prolific trend demonstrates the opportunity for major discovery.
North Abitibi is 50 kilometres south of the Detour Lake Mine operated by Detour Gold Corp and 40 kilometres west of the Casa Berardi Gold Mine currently being operated by Hecla Mining Corp. Cochrane, located 90 kilometres to the southwest, is a major population centre and equipment supplier to the Detour Lake Mine. Access to the property is by truck along well-maintained forestry roads. A number of 4 wheel drive and all-terrain vehicle tracks and trails cross the property providing good access for exploration. Infrastructure in the area has been greatly improved with the all-weather Detour Lake mine road and adjacent power lines located 25 kilometres northwest of the property.
Geology at North Abitibi has largely been compiled from drill core logs, trench mapping, and geophysical interpretation since bedrock outcrops are rare. The property is underlain by a mixed assemblage of west trending, north-dipping felsic, intermediate, and komatiitic mafic volcanic rock, volcaniclastic tuff and sedimentary units of conglomerate, greywacke, argillite, and oxide facies iron formation. These units are intruded by quartz and feldspar-rich sills known as the Spade Lake porphyry. Gold is hosted by stratabound pyritic, sericitic schists up to 40 metres thick within volcaniclastic rocks at the Spade Lake Zone and as pyritic tuffs containing veins of quartz-carbonate-pyrite at the contact between felsic pyroclastic rocks and iron-carbonate rich mafic volcanic rocks at the Road Gold Zone. A number of other gold occurrences are known from historic work but have yet to be investigated by Tri Origin.
The majority of exploration at North Abitibi was conducted by Newmont and Cogema Canada during the 1980’s following discovery of the Casa Berardi gold deposit. Only limited and sporadic campaigns have been conducted since then. The extensive overburden cover has limited the effectiveness of previous exploration campaigns. Tri Origin has compiled and interpreted a large geophysical and diamond drilling database from this previous work, including assay data from over 100 drill holes spread across the length of the property. Twenty-one (21) of these holes reported at least one sample of greater than 2 grams per tonne of gold across a minimum one meter sample interval. Tri Origin has completed conventional and “deep-looking” induced polarization geophysical surveying, excavating, geological mapping and geochemical sampling at the Road Gold Zone and over 25 exploratory diamond drill holes. 3-D modelling of all exploration data has identified extensions to the known gold zones and identified prospective targets for follow-up drilling.
Along-strike and down-dip extensions at both the Spade Lake and Road Gold Zones are primary targets. Spade Lake has been traced by drilling for over 2 kilometres in length and has returned gold values from drilling of up to 23.4 grams per tonne across 1.5 metres, 7.9 grams per tonne across 4.5 metres and 0.52 grams per tonne across 26 metres. Higher grade gold is within broad halos, in places greater than 50 metres thick of low grade, anomalous gold. The Road Gold Zone has returned gold values of 1.34 grams per tonne across 10.1 metres and 17.79 grams per tonne across 1.6 metres. Trenching by Tri Origin exposed the Road Gold Zone at surface and high-grade assays of up to 43 grams of gold per tonne have been returned from grab samples. This work extended the known limits of gold mineralization in the area to over 300 metres in length.
The Spade Lake and Road Gold Zones have been traced over a long distance near surface but have only been drilled to shallow depths. They are at a stage of exploration where detailed diamond drill programs are required to define the extent and economic significance of these gold zones at depth. Other gold occurrences have been identified by drilling elsewhere on the property and detailed geophysical surveying and drilling is warranted to advance these discoveries.
Tri Origin’s expenditures at North Abitibi total over $1.1 million as of the end of 2018.
The South Abitibi project is located 400 kilometres north of Toronto and 10 kilometres southwest of Cobalt in east-central Ontario. It comprises a large, 100%-owned property position of 798 single cell mining claims and 95 boundary cell mining claims covering an area of approximately 210 square kilometers and extends for over 30 kilometres in length in the Temagami-Cobalt region of the Abitibi Greenstone Belt. Initially, Sumitomo Metal Mining Canada Ltd funded an exploration alliance with Tri Origin to explore the South Abitibi property. During the latter part of 2018, Sumitomo informed Tri Origin that it was withdrawing from the alliance leaving Tri Origin with 100% interest in South Abitibi.
South Abitibi is host to a number of partially explored occurrences of gold, copper, nickel and cobalt. The wide variety of commodities occur in differing geological settings and highlight the prospectivity of the property. South Abitibi is surrounded by world-class mining districts; Cobalt (silver-cobalt) 10 kilometres to the northeast, Sudbury (nickel, PGE’s) 120 kilometres to the southwest, Kirkland Lake (gold) 90 kilometres to the north and Noranda (copper, zinc, gold) 100 kilometres to the northeast. It is also adjacent to the Temagami greenstone belt which records past production of iron and gold ores and the Temagami copper-nickel mine which was the first deposit exploited by what became Teck Corporation.
The project targets two valuable commodity types. The first is high-value gold and gold-rich, poly-metallic sulphide deposits within a large expanse of prospective but covered, and hence, previously unexplored Archean-age rock of the southern Abitibi Greenstone Belt. The second are cobalt (silver) deposits of the Cobalt-type associated with Nipissing Diabase which is exposed throughout the property.
The veneer of Proterozoic-age sedimentary rock and Nipissing Diabase throughout the region 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. Pits and diggings at historic cobalt occurrences, now a sought after commodity, have lain dormant for many decades. This provides a compelling, early-stage exploration opportunity at the centre of the most productive metal-producing region in Canada.
The South Abitibi property is nearby a number of towns and mining communities. It is transected by the Trans-Canada Highway 11, powerlines, rail lines and gas pipelines providing all infrastructure required if future development occurs. Numerous roads, trails and lakes make the interior parts of the property highly accessible by truck, ATV, and boat.
The towns of Temagami and Cobalt bracket the South Abitibi property and have a long history of exploration and mining dating back to the turn of the 20th century. The Sherman Mine in Temagami produced iron ore from 1965 to 1990, the Temagami Copper Mine produced copper, silver and gold from 1954 to 1969 and the Kanichee Mine produced copper, nickel, and PGEs sporadically between 1936 and 1976. A number of small mines also produced gold, silver, copper, zinc, pyrite, and cobalt throughout the twentieth century. Within South Abitibi, the Northland Pyrite Mine produced sulphur from massive pyrite lenses in the Archean between 1906 and 1911. The Town of Cobalt was founded during the silver rush of 1905, and the Cobalt area was one of the most prolific silver and cobalt mining districts in Canada until the 1980s, with dozens of mines, both big and small, having been worked.
Two distinct geological environments occur at South Abitibi. The first is comprised of volcanic and sedimentary rock sequences typical of the southern portion of the Abitibi Greenstone Belt. Recently released government data indicates that these rocks are of similar age and composition to those hosting the major gold and base metal deposits of the Bousquet/La Ronde and Noranda Mining Districts to the northeast in Quebec. These prospective rocks are limited in their distribution to small outliers exposed near the central part of the South Abitibi property.
The second geological environment consists of a blanket of younger, Proterozoic-age sedimentary rock and Nipissing Diabase sills which are extensively exposed and cover the Abitibi-belt volcanic rocks. The Nipissing sills, where they intrude both Proterozoic sediment and Archean volcanic rocks host the world-class silver and cobalt deposits only 10 kilometres to the northeast at Cobalt.
Tri Origin’s work indicates that the thickness of cover rock at South Abitibi is not prohibitive to exploring the covered Abitibi belt rocks using modern geophysical techniques and exploration drilling. The majority of Proterozoic cover rocks have seem minimal exploration work as recorded by government assessment records. Consequently, a large area is equally explorable for two, high-value ore types and has been largely overlooked for both over the past 50 or more years.
Tri Origin has completed; a VTEM-Plus airborne electromagnetic and magnetic survey over a detailed survey grid covering the entire property, geological mapping, prospecting and sampling at selected areas, a limited induced polarization geophysical survey and preliminary diamond drilling program.
This work was successful in recognizing a gold-rich corridor associated with the Archean, Abitibi belt rocks which extends under cover and remains unexplored. Tri Origin sampling has returned maximum value of 2.50 grams of gold per tonne from grab samples during outcrop mapping and 1.49 grams of gold per tonne across 0.5 metres from drill core and historic sampling recorded in OGS assessment files reported values of up to 15.36 and 3.80 grams of gold per tonne in Archean rocks. Grab samples of nearby veins and veinlets in Proterozoic cover rocks collected by Tri Origin during outcrop sampling returned maximum value of 1.07 grams of gold per tonne and historic sampling recorded in OGS assessment files reported values of up to 7.89 and 6.24 grams of gold per tonne.
The Nipissing Cobalt property, located 10 km west of Cobalt, Ontario is 100% owned by Tri Origin Exploration Ltd. It is comprised of 51 staked claims covering 10,624 hectares.
The property is underlain by Proterozoic sedimentary rocks and Nipissing diabase sills which are the primary host rocks for cobalt mineralization in the area. These rocks contain a number of historic occurrences of cobalt plus copper, nickel and silver. These occurrences have not been investigated since the 1960’s.
In the central part of the Nipissing Cobalt property, the MacLaren Lake group of occurrences which contain a number of small pits and shafts excavated during the early 1900’s, historic grab samples are reported to have graded up to 0.62 ounces per ton of silver, 2.29% cobalt and 1.08% nickel. A grab sample taken by Tri Origin at a nearby location assayed 2.39 grams per tonne of cobalt. Shallow drill holes completed in the 1950’s reported average assay results of 0.5 ounces per ton of silver and up to 0.2% cobalt over narrow widths (historic assay results from the OGS assessment files).
Tri Origin has compiled historic data related to cobalt (copper, silver, nickel) occurrences on the Nipissing Cobalt property and future work programs will be planned following a site visit this spring.
Tri Origin’s Nipissing Cobalt property provides an opportunity to capitalize on the strong demand predicted for cobalt in the coming years.
