The Red Spring occurrence is located approximately 18 kilometres north of Motase Peak, on a small knoll north of the Squingula River, about 163 kilometres west-northwest of Germansen Landing.
The area lies on the eastern edge of the Bowser basin and is hosted in Lower to Middle Jurassic Hazelton Group rocks. The hostrock is fossiliferous, stylolitic, dolomitic limestone. This intravolcanic reefal limestone is more than 30 metres thick in this area (Assessment Report 20364).
The principal host formation to Red Spring mineralization is a flat-lying to gently dipping intravolcanic fossiliferous, stylolitic, dolomitic limestone horizon that is underlain by fine-grained tuffaceous, argillic and arenaceous units typical of the Hazelton Group. North-south trending faults and shears that have been displaced by later east-west structures are also observed in the area. Faulting appears to have some control on the distribution of the mineralized limestone unit and there is potential for two types of deposits on the Sping (now “Red Spring”) property: 1) sediment-hosted copper-silver deposits, and 2) Volcanogenic Massive Sulphide (VMS) deposits.
In 2007, on the Silver Spring property, outcrops of disseminated silver-rich chalcopyrite (copper) bearing limestone were identified and grab sampled across an area 300 metres wide. Results confirmed documented levels of copper and silver with Appleton’s assays ranging from 0.28 per cent to 1.06 per cent copper, and 1.1 to 30.0 grams per tonne silver” and “reconnaissance traverses also identified an interesting east-west trending zinc-lead soil anomaly 100 to 150 metres wide and 800 metres long, with zinc values between 0.04 and 0.58 per cent and lead values between 29 and 318 ppm. This trend is 700 metres south of the silver-copper rich limestone outcrops”. “Copper-silver mineralization occurs in fine-grained limestone…” and comprises “…fine-grained chalcopyrite and pyrite disseminated through the rock”. Bornite was also reported to be present in trace to very minor amounts (Assessment Report 29622, page 16).
The carbonate contains about 2 to 5 per cent finely disseminated chalcopyrite, pyrite and minor bornite. Calculated from previous drilling, indicated reserves are 4,989,050 tonnes grading 0.5 per cent copper and 11.9 grams per tonne silver (Prospectus, Windflower Mining Ltd., February 1, 1985). A preliminary flotation test indicated that a concentrate grade of 24 per cent copper, 8 grams per tonne gold and 1022.4 grams per tonne silver could be achieved (Assessment Report 20364).
WORK HISTORY
In 1972, the property was first staked by Canadian Superior Exploration and subsequent work included geological, geochemical and geophysical surveys as well as 892 metres of drill testing. In 1976, City Services Mineral Corporation completed three drillholes (347 metres) on the property. Incomplete records indicate that twelve drillholes were placed in 1972 and 1976. In 1983, Windflower Mining acquired the property. A technical crew employed by Inco Exploration & Technical Services Inc. In 1993 acquired samples from the mineralized area for analysis and petrographic studies (Jago, 1993 (private reported referred to in Assessment Report 39024).
In 2007, Appleton Exploration Inc. optioned the “Sping” property and in that year conducted reconnaissance mapping at 1:10,000 scale and collected 321 soil samples and 19 rock samples (Assessment Report 29622). The soil geochemical survey did locate a strong coincident 750 metre long lead-zinc-silver-mercury-cadmium anomaly south of the main mineralized zone.
In 2012, the Red Spring mineral tenures were located by DeCoors Mining Corp. and subsequently transferred to Farshad Shirvani, who holds them in trust for Doubleview Capital Corp. A Doubleview field crew in 2013 conducted a bhttps://minfile.gov.bc.ca/secure/SearchBasic.aspxrief property examination and gathered 10 rock and 20 soil samples (Assessment Report 34643). A geochemical soil survey totaling 293 samples was completed by Doubleview in 2016 (Assessment Report 36450) and another survey in 2018 included geologic mapping and 320 soil samples. In 2019. Mucho Cobre completed 91 kilometres of Airborne Magnetic and Electromagnetic program on the Red Spring utilizing the Versatile Time Domain Electromagnetic (VTEM) system. The survey identified possibly important areas of anomalous low resistivity extending over a kilometre in length and located south of the historic mineral zone. 196 soil samples were later collected over the resistivity low anomaly and field traverses were conducted over exposed outcrops. Doubleview retained ownership.
