The Winslow and Gladhand showings are in an alpine basin on southwest side of Silver Cup Ridge, between elevations 1830 and 2135 metres. The Winslow (L.8680) and Gladhand (L.8681) crown grants are at tree-line at the head of Burg Creek, which flows to the southwest into Trout Lake. The tenures are close to and have largely been worked with those of the Okanagan (L.9127) and Enderby (L.9128) [082KNW024].

The Winslow and Gladhand claims were staked prior to 1904 and most of the development work was completed before 1915. After a lengthy period of dormancy, the old working were rehabilitated and small-scale production started in the early 1930s. However, this was limited to a few tonnes of high-grade shipping ore. In 1939, Winslow Consolidated Limited constructed a 18-tonnes per day "amalgamation and gravity mill" and operated the mine in 1939, 1940 and 1941. At that time, the Winslow vein had underground workings at several levels. The top two adits, which are described in the annual report for 1914, appear to have collapsed by 1937. The No. 1A adit (2066 metres elevation), as later defined by Winslow Gold Corporation, was driven 54.25 metres following the footwall of the vein. The initial 15.24 metres were stoped to surface and, 45.72 metres in, a "Y" shaped split raise was driven upward into the overlying vein. The raise was mined in 1939 and 1940. The No. 1 level adit (2054 metres elevation) is reported to have crosscut for 18.9 metres and drifted on the footwall of the vein for 15.24 metres. A 12.19 metres long stope in the high-grade ore shoot extends through the overlying level to surface. The No. 2 level adit (2024 metre elevation) was driven as a crosscut for 48.77 metres and drifted 24.38 metres on the vein, which was 1.98 to 3.05 metres wide. It evidently missed the high-grade shoot and some workers have speculated that the drift should have been driven to the south, not the north. The No. 3 level adit (1993 metres elevation) was driven for 91.44 metres and intersected the footwall vein, which was 1.32 metres wide at that point. The No. 4 level adit (1902 metres elevation) was collared on the Gladhand crown grant. It was driven from as low an elevation as was feasible so as to encounter the structure a depth, but it was never completed. In 1941, Winslow processed ore from the Okanagan [082KNW024] property for the Le Roi Gold Mining Syndicate. The principals behind Sask-Wainwright Oil and Gas Company acquired the Winslow and Gladhand claims, along with the Okanagan, Enderby [082KNW024], U & I [082KNW023], Alice [082KNW165] and other tenures in the early 1950s and worked on the enlarged property intermittently throughout the 1960s and 1970s. Winslow Gold Corporation acquired the property from Sasko Oil and Gas Limited in 1983 and continued the work. There were several seasons of surface exploration on the property following Granges Exploration Limited's announcement of good drill results on the Goldfinch property (4 kilometres north of Camborne) in the mid 1980s. Winslow Gold Corporation conducted geological, geochemical and geophysical programmes in 1983. In 1987, it diamond drilled 7 holes for an aggregate depth of 479.45 metres to test the vein. The following year, Northern Crown Mines Limited optioned the property and continued the exploration program.

The Trout Lake area is underlain by a thick succession of sedimentary and volcanic rocks of the Badshot Formation and Lardeau Group near the northern end of the Kootenay arc, an arcuate, north to northwest trending belt of Paleozoic and Mesozoic strata that is now classified as a distinct, pericratonic, terrane. The arc rocks are bordered by Precambrian quartzite in the east and they young to the west, where they are bounded by Jurassic-age intrusive complexes. They were deformed during the Antler orogeny in Devonian-Mississippian time and were refolded and faulted during the Columbian orogeny, in the Middle Jurassic. A large panel, the "Selkirk allochthon", was later offset to the northeast by dip-slip motion along the Columbia River Fault.

The Badshot Formation is composed of a thick Cambrian limestone that is a distinctive marker horizon in the Trout Lake area. It is underlain by Hamill Group quartzite and it is overlain by a younger assemblage of limestone, calcareous, graphitic and siliceous argillite and siltstone, sandstone, quartzite and conglomerate, and also mafic volcanic flows, tuffs and breccias, all of which belong to the Lardeau Group. The rocks are isoclinally folded and intensely deformed, but only weakly metamorphosed. They occur as intercalated beds of marble, quartzite and grey, green and black phyllite and schist. Fyles and Eastwood (EMPR BULL 45) subdivided the group into six formations (Index, Triune, Ajax, Sharon Creek, Jowett and Broadview) of which the lowermost (Index) and uppermost (Broadview) are the most widespread. The Triune (siliceous argillite), Ajax (quartzite) and Sharon Creek (siliceous argillite) are restricted to the Trout Lake area. The Jowett is a mafic volcanic unit.

The Winslow and Gladhand claims are underlain by grey phyllite and siliceous schist of the Broadview Formation, the uppermost unit of the Lardeau Group. The rocks are on the southwest flank of the Silver Cup Ridge. They are highly deformed and folded, and have a pronounced northwest trending schistocity and a moderate to shallow dip to the northeast. The underlying Jowett Formation, which is a mafic volcanic unit, is exposed off the property, uphill to the northeast. The area was mapped by James Millar and Associates in the early 1960s (EMPR PF: Reports by B.W.W. McDougall, 1946; and J. Millar and Associates, 1963). The Winslow vein strikes 020 and dips 55-60 degrees to the east. It straddles Burg Creek and was originally found and traced by tracking oxidized quartz float back to outcrop. The vein is exposed in several surface cuts and four main adits, driven at different elevations on a steep hillside. It has been explored for 91 metres vertically and 122 metres horizontally. The Winslow vein consists of two parallel quartz-carbonate veins, that aggregate up to 3.66 metres in width, and are separated by a 0.46 to 1.22 metres wide panel of schistose countryrock. The composite vein follows an old fault zone with little or no post mineral movement and no significant cross faulting. However, the principal shoot may be fixed by a cross-vein striking 012 degrees. The main "vein" contains pyrite with lesser amounts of galena, sphalerite, chalcopyrite and rare free gold. These are unevenly distributed and the best gold values were found in a pipe-like shoot. The gold content of the vein was found to decrease horizontally away from the shoot. The principal lens is 12.2 metres in horizontal length and of unknown, but probably far greater depth extent. Near surface, the vein is 2.44 metres wide and well mineralized with pyrite. However, much has leached out and the rock has a honeycombed appearance. Free gold has been found in cells left by oxidation of pyrite. An average sample of oxidized ore bagged for shipment in 1914 assayed 185.14 grams per tonne gold and 157.71 grams per tonne silver. Fresh vein material contains approximately 13.71 grams per tonne gold and 20.57 grams per tonne silver.

James Millar and Associates mapped the property for Trans Western Oils Limited in 1963 and identified several other veins in the area. The Winx Vein is 1645 metres northwest of the main Winslow showings. It strikes to the northeast and cuts the countryrock phyllites at a low angle. It is approximately 0.46 metre wide and contains galena and pyrite; it resembles mineralization found at the Silver Cup mine [082KNW027]. The Winext No 1 vein is subparallel to the Winslow vein and dips 70 degrees east. It is 1.83 to 2.44 metres wide and contains some pyrite but little galena. The Winext No 4 vein is similar. Both show continuity along strike and, based on their locations, they may be the same vein.

In 1987, Winslow Gold Corporation drilled seven holes into the Winslow vein, for an aggregate total depth of 479.45 metres. Four holes intersected the vein. Two were abandoned and one missed. The intercepts suggest a vein with sharp contacts of between 5 and 8.3 metres true width. The vein was less well mineralized than expected, based on results from surface samples. The drill core shows that the vein is composed of white quartz with clots and seams of coarse iron carbonate and small xenoliths and panels of argillite, and traces of pyrite. Pyrite also occurs as rare massive bands. Sphalerite and chalcocite were located in small amounts. The quartz is commonly crackle brecciated and the fragments are cemented by siderite. The vein contains vugs with secondary quartz. Gold grades were lower than expected and the vein is probably poddy. Gold values decreased from south to north away from the old workings and appears to be related to pyrite content.
