The Harvey Gold occurrence is located at an elevation of approximately 2250 metres on a south-facing slope, approximately 5 kilometres southeast of Niut Mountain.
The area of the Harvey Gold showing is underlain by a strongly faulted region just west of the Niut fault near the contact of basaltic rock of the Middle to Upper Triassic Cadwallader Group with a tonalite pluton that extends about 35 kilometres to the northwest. The Tchaikazan fault bounds the Cadwallader Group volcanics and the Cadwallader Plutonic Suite intrusion about 3 kilometres to the west of the Harvey Gold showing.
The rocks present are mainly felsic, intermediate and mafic volcanic flows, agglomerate, breccia and tuff, with minor sedimentary rocks (Geological Survey of Canada Open File 1163; Assessment Reports 10303, 17200). These rocks strike northwest. All rocks are intruded by numerous dikes and sills, many of which are probably related to a relatively large quartz diorite intrusion to the northwest. The dikes are composed of porphyritic quartz diorite and feldspar-quartz porphyry, or mafic rock; they trend mainly west-northwest or east-northeast, and dip steeply north.
Locally, an area of propylized, silicified and brecciated andesitic flows host east-west–trending quartz and quartz-carbonate veins and stockworks, up to 3 metres wide. Mineralization consists of chalcopyrite with possible minor scheelite and/or powellite. Limonite and malachite are also reported. The veins are thought to be of possible mesothermal origin.
In 1991, a grab sample (H-7) assayed 4.22 grams per tonne gold, 16.4 grams per tonne silver and 0.239 per cent copper (Property File - 808 Exploration Services Ltd. [1991-05-01]: Porphyry Intrusive System with Copper-Gold Mineral Potential - Harvey Property - Confidential Overview).
In 1992, a chip sample (910724-7) assayed 0.75 gram per tonne gold and 0.000975 per cent mercury across 1.5 metres, whereas a grab sample (910724-5) assayed 0.228 per cent lead, 25.2 grams per tonne silver and 0.16 gram per tonne gold (Property File - 808 Exploration Services Ltd. [1992-06-01]: Report - Porphyry intrusive system with copper-gold mineral potential - Harvey property).
WORK HISTORY
In 1982, Vanco Explorations examined the area as the Fly claim. In 1987, a program of geochemical sampling and prospecting were completed on the area as the Gossan 1-2 claims.
In 1991 and 1992, 808 Exploration Services examined and sampled the area as the Harvey property for or with Placer Dome. The higher gold values (4.22 grams per tonne) did not become public until Placer Dome gave its exploration files to BC Geological Survey (Property File) in the late 1990s.
In early 2011, Geotech Ltd. of Aurora, Ontario conducted helicopter-borne magnetic and Z Axis Tipper Electromagnetic (ZTEM) geophysical surveys over the Buzz property of behalf of Strategic Metals (Assessment Report 32233). A total of 772 line kilometres of EM and magnetic data were recorded. In spring of that year, the data from those surveys were evaluated by Condor Consulting (as follows in 2012). In 2012, Strategic Metals compiled data from Condor Consulting’s geophysical interpretation together with previously obtained geochemical and geological data collected by other operators (Assessment Report 33014). MINFILE occurrences within the area of the geophysical survey include: Nuit Mountain (092N 020), Rusty (092N 044), Anthony (092N 064), Clipboard (092N 065), Fly (092N 044), Fly Creek (092N 074) and Harvey Gold (092N 073). The northernmost resistivity high (R2) coincides with a large magnetic high. The Gold and Creek showings lie immediately west of the eastern conductivity high, near the surface trace of Niut Fault.
In 2015, a total of 28 rock samples were collected from the Fly, Downs and Niut Mountain showings. The other showings were not revisited in 2015.
In 2021, Goldplay Mining Inc. conducted prospecting and geochemical sampling on the Goldstorm South project.
