The Hoey occurrence is situated on the west-facing slope of a small, steeply incised creek draining south to Hatchau Lake. The showings are about 120 metres above the lake and consist of several veins and lenses of specularite with magnetite, chalcopyrite, and pyrite, and are clustered on the steep valley slope. The area is also marked by several calcite veins variably mineralized with chalcopyrite and minor pyrite. Erythrite has also been noted in the showing area.
The mineralization occurs in an area of Late Triassic-Early Jurassic fine-grained intrusive rocks ranging from diorite to monzonite in composition. Upper Triassic Stuhini Group dark green andesite and cherty tuffaceous rocks are present and calcareous argillaceous rocks are reported at lower elevations to the south. Rock sampling yielded up to 0.17 per cent copper, 6.1 grams per tonne gold and 5.1 grams per tonne silver (Assessment Report 14802).
The D showing (Lisle Prospect) is located about 1.5 kilometres north of the Hoey mineralization. Trenches expose andesite, bedded tuff and porphyry. Three samples collected in 1985 yielded 1.3 to 3.8 grams per tonne gold (Assessment Report 14802).
West Gossan and Hoey high gold and copper rock and soil anomalies are located 1.4 kilometres southwest and 1 kilometre south, respectively, of the Lisle copper-gold rich porphyry deposit. Anomalies extend over an area of 550 by 850 metres at the Hoey gold area and 1,400 by 700 metres at the West Gossan area. Also, at the Hoey gold area, some rock samples yielded results as high as 8.11 grams per tonne gold, 7 per cent copper and 0.5 per cent cobalt (Doubleview Capital Corp, News Release, Oct.19, 2017). A total 987 soil sample and 181 rock samples of the West Gossan and Hoey Gold are plotted.
Work History
Exploration in the region dates to before World War II when several properties (e.g. Copper Creek, 104J 005) were mapped and sampled. Prospector F. Hoey discovered and staked a prominent gossan (the present Hoey showing) in 1963. In 1969, Skyline Explorations acquired the ground surrounding the Hoey prospect and conducted some geochemical work. The Colorado Corporation held the Pat 1-12 and 17-30 claims and during 1969 and 1970 a soil geochemical survey was carried out. The property was acquired by Utah Mines in 1977 and soil sampling, an induced polarization (IP) survey and bulldozer trenching were performed in developing the prospect. In 1984, the Moon claims were staked for United Cambridge Mines to cover the Hoey showing. An airborne magnetics/VLF-EM survey was flown over the claims in 1987. Subsequent work (1988) by United Cambridge Mines has included ground geophysics and soil sampling. Three anomalous areas (including the Hoey showing) were outlined through soil geochemistry and ground VLF-EM geophysics. The claims were restaked in 1990 for Consolidated Cambridge Mines Ltd. and a brief follow-up program of rock geochemical sampling and prospecting was carried out in the fall of 1990; a total of 17 rock and soil samples were collected for geochemical analysis. In summer 2011, Doubleview Capital Corp. negotiated an option to acquire a 100 per cent interest in the Hat property and in September completed a 479 sample mobile metal ion geochemical soil survey.
In 2014, Ashburton Ventures Inc. collected 6 rock samples on their Hackett Property adjacent the Hat property on its east side. The Hoey prospect occurs approximately 350 metres downstream (south) of Ashburton sample #16846, and approximately 50 to 150 west of the western boundary of the Hackett Property. Prospecting of the steep slopes of Big Creek uncovered two occurrences of moderately to strongly limonitic and gossanous material with trace malachite and minor chalcopyrite and pyrite. Two locations were discovered, trending roughly east-west, based on limited exposure. The initial mineral showing discovered (sample numbers 16846 and 16847) yielded 24 parts per billion and 0.594 gram per tonne gold, and 0.06 and 0.3 per cent copper, respectively. Approximately 150 metres upstream on Big Creek, from the first location, another strongly oxidized showing returned 0.13 gram per tonne gold and 0.09 per cent copper (Assessment Report 34955).
In September of 2017, Doubleview Capital Corp. stated that it had compiled all available data from the Hoey and West Gossan mineral zones. Each zone is located more than one kilometre from the Lisle Zone that has been the focus of much of the Company’s work. Neither zone has been investigated by geophysical surveys or drilling but both have strong surface mineralization with copper, gold, silver, and cobalt values.
In 2018, Glacier Lake Resources Inc. completed two reconnaissance surface exploration programs on its Silver Vista and Hackett properties, the latter of which was adjacent the Hoey showing (Press Release, Glacier Lake Resources Inc., September 4, 2018). In total, 26 rock samples were collected from the area of the 2014 sampling in a steep ravine on the western flank of the property. Most samples collected were gossanous fine-grained mafic volcanics, many of which contained quartz-carbonate veins/veinlets. In addition, 33 soil samples were collected using augers from within a target zone projected as the extension of the Hoey zone. Results of the soil survey were strongly anomalous in copper values, with a peak of 458 parts per million copper (Assessment Report 37802). Of the 26 rock samples taken in 2018, sample R 29359 yielded the best value of 0.032 gram per tonne gold, 1.2 grams per tonne silver and 0.14 per cent copper (Assessment Report 37802). The sample consisted of strongly gossanous (oxidized), fractured, mafic volcanics, close to anomalous sample 16848 taken in 2014.
On June 19, 2018, Doubleview Capital Corp. announced that it had entered into an option agreement with Hudbay Minerals Inc. on the Hat Copper-Gold Project. Under the terms of the Option Agreement, Hudbay would be the operator. By July 24, 2018, Hudbay had initiated a deep-penetrating induced polarization (IP) geophysical survey program on the Hat project, with intention of covering the entire exploration area. By May 2019, Hudbay's work had revealed a chargeability anomaly that extended at least 1250 metres vertically and was linked at depth from the Lisle prospect to the Hoey (Doubleview Capital Corp, News Release May 28, 2019).
On October 17, 2019, Doubleview announced that it had resumed diamond drilling at its Hat gold-copper porphyry property with one hole reported to have shown good visual results on the Lisle zone. No further drill results were published to date, January 8, 2019.
