The Fox (Discovery) Mo-W showing is located along a west-flowing segment of Deception Creek, about 4 kilometres northeast of No Name Lakes.

The skarn mineralization is hosted in metasedimentary rocks of the Proterozoic-Paleozoic Snowshoe Group, along the south margin of a granitic pluton informally referred to as the Deception Stock.

The sparse bedrock exposure in the vicinity of the Fox showings includes skarn, calc-silicate schist, quartz-biotite schist and quartzite, locally cut by aplitic, pegmatitic and granitic dikes. Layering and schistosisty show gentle to moderate dips to the southwest.

At the Discovery molybdenum zone, subcrop of garnet-epidote-pyroxene skarn, locally with distinct vesuvianite crystals, contains patches, fracture-fillings and disseminations of molybdenite.

The area north of the showings was covered by a geological and geochemical exploration program in 1982, which was implemented to follow up a regional geochemical survey that identified anomalous tungsten concentrations in heavy mineral samples in the Deception Creek drainage system (Assessment Report 10641). The Deception Stock, comprising garnet-bearing muscovite-biotite granite, was recognized at this time, but not mapped in detail, and soil samples from around the eastern and northern margins of the stock were found to be slightly anomalous in tungsten. Dave and Catherine Ridley located the southern contact of the Deception Stock and adjacent skarn alteration in 1997, while prospecting along the newly constructed 7200 logging road. Further prospecting in 1999 led to the discovery of molybdenum-bearing skarn and initial staking of the Fox mineral claims (Assessment Report 26275). Subsequent work included grid construction, soil geochemical surveys, a ground magnetometer and VLF-EM geophysical survey, and additional prospecting and claim staking (Assessment Reports 26611, 26943). The property was optioned to Happy Creek Minerals Ltd. in December 2004, and an exploration program comprising grid layout, soil and rock geochemical sampling, prospecting and geological mapping was carried out in 2005. This program led to the discovery of the Nightcrawler tungsten zone, 1 km east of the Discovery molybdenum zone (Assessment Report 27886). Between 2006 and 2011, Happy Creek Minerals completed various exploration programs on the property and associated occurrences. This work included diamond drilling programs in 2006 and 2010, totalling 4,486 metres over 16 holes.

Samples from the Discovery zone have returned up to 4.9 per cent molybdenum (Assessment Report 27886).

In 2006 and 2007, drill hole 07F-08 intersected multiple horizons of mineralized skarn at the Discovery zone, including: 7.0 metres of 0.13 per cent WO3 at a downhole depth of 236.8 metres and 0.70 metres of 0.30 per cent WO3 at a downhole depth of 315.0 metres. Limited drilling in the underlying quartz monzonite stock at the Discovery zone assayed: 0.85 metres of 0.293 per cent molybdenum at a downhole depth of 361.5 metres in drill hole 07F-09, and; 3.9 metres of 0.219 per cent molybdenum at a downhole depth of 186.9 metres in hole 07F-13 (Assessment Report 30008).

During 2012 through 2014, Happy Creek Minerals continued programs of geological mapping and drilling on the Fox property, primarily on the RC (MINFILE 093A 259) zone and surrounding area. In 2015, Happy Creek Minerals completed a program of airborne magnetic and radiometric surveys, soil sampling, prospecting and geological mapping. Six diamond drill holes, totalling 1500 metres, were also completed on the Creek zone near the east end of the Nightcrawler (MINFILE 093A 258) zone.

In 2016, Happy Creek Minerals completed a program of trail construction, soil sampling, surface chip and channel sampling in 11 trenches, rock sampling, geological mapping and 28 diamond drill holes, totalling 2330 metres, on the BN, BK and RC zones to the north. At the South Grid, a machine trench cleared off an 8 metre long and approximately 0.60 metre wide portion of surface outcrop and grab samples collected at two metre intervals returned 0.22 to 0.54 per cent tungsten trioxide (Desautels, P. (2017-03-10): NI 43-101 Resource Update for the RC Zone and Maiden Resource Estimate for the BN Zone of the Fox Tungsten Project).

In 2017, Happy Creek Minerals completed a further 66 diamond drill holes, totalling 6983 metres, on the Fox property along with prospecting, geological mapping and hand trenching. Drilling results from the South Grid zone yielded up to 0.496 per cent tungsten tri-oxide over 3.07 metres in hole F17-61(Desautels, P. (2018-02-27): NI 43-101 Resource Update for the RC and BN Zones and Maiden Resource Estimate for the BK Zone of the Fox Tungsten Project). This is considered a discovery of potentially economic grade in this new, road accessible target that is underlain by a 1.5 km by 500 metre tungsten in soil anomaly.
