The Stoyoma Mountain (White) occurrence is located on a south-facing slope in the headwaters of Ainslie Creek, approximately 8 kilometres west-southwest of Stoyoma Mountain.
The Stoyoma (Eke-Waki) Mountain area is underlain by Late Triassic and/or Early Jurassic granitic rocks assigned to the Mount Lytton Complex. This complex comprises mainly diorite and granodiorite which host local pendants of carbonate rocks of Paleozoic and Mesozoic age.
Several magnetite(-copper) skarns and "hematite showings" appear to have been located adjacent to intrusive/limestone contacts. Base metal assay values as high as 2 per cent copper and 61 per cent iron across 12.19 metres, local silver values up to 68.57 grams per tonne and very low gold values were reported from showings consisting of massive magnetite, pyrite, pyrrhotite, chalcopyrite and hematite (White, 1958-1960 - Property File). The largest magnetite skarn is described as being 3.66 metres wide by 182.88 metres long.
In 2017, a rock sample (CP-JAW-003) from a roadcut outcrop of chlorite-sericite altered, foliated intermediate intrusive with pyrite, located approximately 600 metres down slope to the south west, yielded 0.81 per cent copper, 17 grams per tonne silver and 0.13 gram per tonne gold, while a sample of biotite-pyrite-chalcopyrite bearing shear zone, described as being located in the eastern part of the property, yielded 0.24 per cent copper (Price, B.J. (2017-10-16): Technical Report - Jack White Property).
In 2018, a sample (JW18-OF-007R) of meta-gabbro with biotite, garnet and pyrite, taken from the outer edge of the strong magnetic core of the White occurrence, assayed 0.475 per cent copper (Assessment Report 38147).
Another zone of semi-massive to massive magnetite with pyrite, chalcopyrite and pyrrhotite mineralization, referred to as the Tampa zone, is located along an east-west–trending ridge, approximately 2 kilometres west of the main Stoyoma Mountain (White) occurrence.
In 2018, eight rock samples from the Tampa zone yielded from 13.11 to 51 per cent iron (Assessment Report 38147).
Work History
The skarn mineralization was first identified in the late1950s by prospectors including Jack White and W.E. Harvey.
In 1959, Noranda Explorations completed a dip-needle survey on the clams.
In 1965, numerous 3 to 6-metre long packsack diamond drill holes were reported to have been completed.
In 1974, the area was staked as the Tee and Hoodoo claims and packsack drill holes, to 3 metres deep, were deepened to 6 metres by explosives.
During 2010 through 2012, Homegold Resources Ltd. held the claims. Programs of prospecting was completed during this time.
In 2016 and 2017, Kal Minerals Corp. completed programs of prospecting, geochemical (soil, silt and rock) sampling and a ground magnetometer survey on the area as the Jack White property. This work identified additional zones of magnetite in outcrops to the west.
In 2018, Kal Minerals Corp. completed a further program of geochemical (rock and soil) sampling, geological mapping, an 8.4 line-kilometre induced polarization survey and a 60.0 line-kilometre ground magnetic survey on the Jack White property.
In 2019, Island Time Exploration Ltd. completed a program of soil sampling on the area immediately north of the occurrence as the Gravity property.
