The Sinkut Mountain occurrence is located approximately 1 kilometre south of the peak of Sinkut Mountain, 25 kilometres south-southeast of the community Vanderhoof and 81 kilometres west-southwest of Prince George.
The region is underlain to the west by the Mississippian to Triassic Cache Creek terrane and to the east by the Quesnel terrane and the Omineca Belt. Middle Jurassic and Paleogene volcanic and sedimentary rocks overlie the Cache Creek Group. The boundary between the Quesnel and Cache Creek terranes is probably the southern extension of the Pinchi fault system. Ultramafic rocks of ophiolitic affinity, now variably deformed and metamorphosed, were tectonically emplaced within the Cache Creek Group.
The Sinkut Mountain occurrence consists of chrysotile asbestos within serpentinized peridotite. Fibrous anthophyllite also occurs in the area, in a road cut 0.8 kilometres west of the forestry lookout on Sinkut Mountain. The main rocks found within the Sinkut Mountain area are metamorphic and serpentinite ultramafic.
In 1970, John M. Ashton conducted a reconnaissance magnetometric survey on his two claims that extended approximately 1.7 kilometres; four magnetic anomalies were determined by the survey.
In 2006, Seel Enterprises Limited, the owner of the Hoof 1 claim, conducted a geochemical survey consisting of 150 soil reconnaissance samples and 89 rock samples. The soil samples were taken at 100-metre intervals on lines 250 metres apart, whereas the rock samples were taken at 100-metre intervals on lines 100 metres apart. The program was designed to explore for bulk tonnage metal deposits of magnesite and nickel. Rock samples assayed up to 0.33 per cent nickel and 27.06 per cent magnesium (samples 62940N 36010E and 63680N 36000E, respectively; Assessment Report 29227). Additionally, lower values of nickel, around 0.27 per cent, were found approximately 1 to 1.5 kilometres north-northeast of the Sinkut Mountain occurrence—on the north side of the peak of Sinkut Mountain.
In 2007, Porpoise Bay Minerals Limited took possession of the Hoof and Porpoise claims and conducted a 160-soil and 81-rock sample survey on the property. Twenty-five of the soil samples were elevated in nickel and magnesium. The rock samples returned consistently anomalous in nickel and magnesium reaching values of 0.34 per cent nickel and 24.72 per cent magnesium (samples 62708N 36215E and 64314N 35889E, respectively; Assessment Report 30105).
In 2008, Driftwood Drilling was contracted by Porpoise Bay Minerals Limited to perform a 10-hole diamond drilling program. Drillholes 08-HF-01 and 08-HF-02 displayed the highest anomalous values of magnesium. Drillhole 08-HF-01 assayed 27 per cent magnesium within two parts of its core, from 3.05 to 5.18 metres and 26.52 to 29.57 metres (Assessment Report 30238). Drillhole 08-HF-02 also had assay values of 27 per cent magnesium from 7.92 to 10.97 metres and 14.02 to 17.07 metres (Assessment Report 30238). Nickel values remained fairly consistent around 0.26 per cent throughout all ten holes.
In 2009, a 4-square kilometre geological mapping project and a ground magnetometer survey was completed on the Hoof property. The intention of the surveys was to determine the size, lithological variation, alteration style and structural features of the peridotite body on the central portion of the property.
In late 2011, Falcon Drilling Limited performed a short, three-BTW diamond drill hole program, totalling 375 metres, 3 kilometres southeast of the Sinkut Mountain occurrence. Drilling encountered altered peridotite similar to that found in the 2008 drilling program.
Rupert Seel oversaw the 6-hole 2012 diamond drilling program, which was also performed approximately 3 kilometres southeast of the Sinkut Mountain occurrence. Similar to the results in the 2008 and 2011 drilling programs, serpentinized peridotite was found and assayed similar results.
