The Gentleman-Julep occurrence is located approximately 36 kilometres southeast of the community of Dease Lake and 21 kilometres east of Highway 37.
The area of the Gentleman-Julep Trend is underlain by Jurassic-aged mafic and felsic flows and volcanic breccia of the Horn Mountain Formation, Hazelton Group (Fieldwork 2016). The first discoveries on the Andalusite property were the Gentleman vein and the Julep showing.
The Gentleman vein is up to 20 centimetres wide and contains quartz-carbonate-magnetite sulphide (primarily chalcopyrite) with heavily altered and mineralized vein selvages. Three samples from the Gentleman vein showing were collected 17 metres apart; the best assay was 1.84 grams per tonne gold, 17.3 grams per tonne silver and 2.25 per cent copper (Assessment Report 37404, page 14).
The Julep showing is about 140 metres southwest of the Gentleman vein and consists of a feldspar porphyritic mafic intrusion with disseminated clots and veins of tetrahedrite, chalcocite, and secondary malachite and azurite. Grab samples from the Julep showing collected 21 metres apart assayed 0.09 gram per tonne gold, 21.1 grams per tonne silver and 2.72 per cent copper and 1.18 grams per tonne gold, 11.2 grams per tonne silver and 1.14 per cent copper (Assessment Report 37404, page 14).
The strike length of the Gentleman/Julep area was 140 metres long, as defined in 2017. In 2018, it was expanded by further prospecting and sampling to at least 550 metres and became known as the Gentleman-Julep Trend.
Mineralization on the Gentleman-Julep Trend is the same as that of the Tennessee Trend, comprising 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 And Ginger (104I 140), located 1.5 kilometres southwest, 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. 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 assayed up to 3.04 per cent copper, 68.9 grams per tonne silver, and 0.23 gram per tonne gold, the Tennessee Trend (Assessment Report 30590). The best sample from the Gentleman-Julep Trend for 2018 was 3.33 per cent copper, 2.85 grams per tonne gold and 22.1 grams per tonne silver (Press Release - Triumph Gold Corp., January 9, 2019). Triumph Gold also increased the Andalusite Peak land package from 9.87 square kilometres to 31.67 square kilometres via staking.
