The Windsor showing is underlain by intrusive rocks of the Late Triassic-Early Jurassic Iron Mask batholith and andesitic volcanics of the Upper Triassic Nicola Group. Old workings spaced along a line 79 metres long trending 280 degrees consist of an inclined shaft more than 6 metres deep and several trenches and shallow pits. Hostrock is Nicola andesitic volcanics. The exposures in the workings indicate that a fault, striking 280 degrees and mineralized across a width of 0.9 metre, gives place westward to two or more fractures whose strike is 300 degrees. The fractures dip about 60 degrees to the north. Mineralization consists of chalcopyrite and abundant coarsely crystalline pyrite in calcite and quartz gangue. The sulphides extend into the adjacent sheared greenstone. Samples of the best material on the dumps at the shaft and the large pit assayed 1.5 and 0.69 per cent copper respectively (Minister of Mines Annual Report 1956).

In 1956, Inland Copper Mines Ltd. drilled two shallow AX diamond-drill holes to test the showing. Minor pyrite-magnetite mineralization was intersected in drillhole W2, 91 metres northwest of the shaft. The hole passes from greenstones into strongly albitized and brecciated diorite of microdiorite of the Cherry Creek unit of the Iron Mask batholith. Drillhole W1 passes through picrite basalt into greenstones and back into picrite. The picrite is part of the Picrite unit of the batholith.

In 1964, Rolling Hills Copper Mines Limited conducted a widely spaced induced polarization survey totalling 37.5 line kilometres over several claim groups. In 1976, four percussion-drill holes totalling 365.7 metres were drilled, 24 kilometres of induced polarization survey and a soil geochemical survey completed on the Sun claim on behalf of L.M.C. Resources Ltd.
