The Tennessee occurrence is located approximately 36 kilometres southeast of the community of Dease Lake and 21 kilometres east of Highway 37.
The area of the showing is underlain by Jurassic-aged mafic and felsic rocks of the Horn Mountain Formation (Hazelton Group) comprising mafic feldspar porphyry and mafic and felsic flows (Fieldwork 2016).
In 2018, on the Andalusite property, a newly identified 1000 by 300 metres mineralized trend (the Tennessee Trend) was delineated on a ridge 1.5 kilometres west of the Gentleman-Julep Trend (104I 153). This trend is defined by 15 new and historical samples with greater than 0.5 per cent copper, including grades up to 67 per cent copper, 500 grams per tonne silver, and 2.8 grams per tonne gold (Press Release - Triumph Gold Corp., January 9, 2019). The Tennessee mineralized trend extends at least one kilometre along the ridge and was sampled on both sides of a plateau where the ridge widens to 300 metres and is open in all directions.
Mineralization on the Tennessee Trend ridge is the same as that of the Gentleman-Julip ridge which comprises veins and volcanic breccia-fill with quartz plus or minus calcite plus or minus epidote plus or minus actinolite plus or minus chlorite gangue and variable proportions of chalcopyrite, bornite, chalcocite, malachite and azurite. Copper-bearing minerals also occur along fractures, filling vesicles, and disseminated in wallrock adjacent to veins. The alteration mineral assemblage (quartz-andalusite-pyrophyllite) documented in the Andalusite Peak alteration zone represents the highest temperature advanced argillic alteration identified in the belt. Quartz-magnetite veins were also reported.
In 2008, Paget Moly Corp. conducted a stream sediment and rock sampling program on what later was the Andalusite Peak property (64 rock and silt samples were collected for analysis). See the And Ginger occurrence (104I 140), located 766 metres south of the Tennessee occurrence, for further details.
In 2017, exploration of the Andalusite Peak property included prospecting, the collection of 24 rock samples and some geological mapping. Assays defined two new gold-silver-copper occurrences, the Julep showing and Gentleman vein (104I 153, located 1.7 kilometres east of the Tennessee occurrence). The Julep showing is about 140 metres southwest of the Gentleman vein.
In July 2018, Triumph Gold Corp. conducted two days of prospecting and alteration mapping on the Andalusite Peak property. Sampling in 2018 focussed on the area south of the alteration zone and was conducted on two ridge lines, the one that hosts the Julep and Gentleman showings (Gentleman-Julep Trend), and another parallel ridge 1.5 kilometres to the west where historical grab samples graded up to 3.04 per cent copper, 68.9 grams per tonne silver and 0.23 gram per tonne gold (Assessment Report 30590); the new Tennessee Trend prospect (this description). Triumph Gold also increased the Andalusite Peak land package from 9.87 to 31.67 square kilometres via staking.
In 2019, Rio Tinto Exploration Canada Inc. conducted a reconnaissance sampling program on the Andalusite Peak property by collecting samples (6 silt, 83 rock) for geochemical characterization and TerraSpec hyperspectral analyses. Samples were collected from mineralized, veined and/or altered outcrop, subcrop, and proximal float. A few stream sediment samples were also collected from local drainages.
