The Rhyolite occurrence is located at an elevation of approximately 1260 metres on a northeast-facing slope, south of Meadow Creek and approximately 1.5 kilometres northwest of Homfray Lake.
The area straddles a northwest-trending contact between two volcanic sequences of the Upper Triassic Nicola Group. To the west are plagioclase, plagioclase-augite intermediate pyroclastic and epiclastic breccia, conglomerate, tuff, sandstone, local shale and augite porphyry bodies. The central portion to the east is underlain by aphanitic pillowed mafic flows. The contact between these two sequences hosts the Rhyolite occurrence.
The Rhyolite showing is underlain by grey, green or black amygdaloidal basalt of the Upper Triassic Nicola Group. Varicoloured calcite amygdules occur within an aphanitic groundmass. Several beds of maroon to green volcaniclastic breccia occur within the basalt and contain maroon, subrounded to subangular clasts ranging up to 30 by 15 centimetres. Two northwest-trending, light grey-green, aphanitic, siliceous and pyritic felsic dikes, 3 to 4 metres wide, also occur.
Mineralization occurs in amygdaloidal basalt, andesite and rhyodacite near the flow-volcaniclastic contact and is related to narrow quartz-carbonate veinlets within shears. Several old trenches indicate the shear zone strikes approximately 335 to 345 degrees and dips steeply west. Pyrite is present with minor chalcopyrite, azurite, malachite and sphalerite.
In 1986, an outcrop sample from the Rhyolite grid is reported to have yielded 1.76 per cent copper, 1.53 per cent zinc and 26.8 grams per tonne silver (Assessment Report 14959).
In 1987, a rock sample (87-005) from a historical trench yielded 0.055 gram per tonne gold and 5.5 grams per tonne silver, whereas a float sample (87-008), taken approximately 75 metres north of the previous sample, yielded 0.274 per cent copper, 0.629 per cent zinc and 6.2 grams per tonne silver (Assessment Report 18048).
In 1988, samples (88-02 and 88-04) yielded values up to 4.1 grams per tonne silver, 0.377 per cent copper and 0.218 per cent zinc (Assessment Report 18048).
Work History
During 1986 through 1988, Western Resources Technologies completed programs of prospecting, geological mapping, geochemical (rock, silt and soil) sampling and geophysical (induced polarization, electromagnetic and magnetometer) surveys on the area as the WRT claims.
In 1992, Grant Crooker completed ground magnetic and electromagnetic surveys on the area immediately south of the occurrence as the LC 1 and Hom 1-6 claims.
In 2006, Auror Capital Corp. completed a photogeological (lineament array) analysis on the area as the Katrina claim.
During 2013 through 2015, Laurence Sookochoff, on the behalf of Guy and Christopher Delorme, carried out programs of structural analysis and ground magnetometer surveys on the area as the Bertha property. In 2016, Victory Resources Corp. completed a program of structural analysis and geophysical surveys on the area. In 2017, Laurence Sookochoff completed a program of historical geological, geochemical and geophysical data analysis and evaluation on the area. In 2018 and 2019, Kenneth Ellerbeck completed programs of prospecting and minor rock sampling on the area as the Rhyolite claim.
In 2020, Baden Resources Inc. completed a program of rock sampling, photo interpretation (structural analysis) and a 32.8 line-kilometre ground magnetic and electromagnetic survey on the area as the Bertha property.
