The Ohio occurrence is located on the west side of Lyle Creek, 1.75 kilometres from its confluence with the Kaslo River. The Whitewater occurrence (082KSW033) is 1.5 kilometres to the west.

Silver-lead-zinc mineralization occurs in the Triassic Slocan Group, locally consisting primarily of black fissile phyllites with interbedded limestone, calcareous phyllites and brown gritty quartzites. The general structural trend is 310 degrees, dipping generally southwesterly. Greenstones and ultramafic rocks of the Permian Kaslo Group unconformably underlie the Slocan Group to the east, also hosting silver-lead-zinc mineralization. Satellite stocks, dikes and sills are generally correlative with the Nelson batholith to the immediate south. Late stage lamprophyre dikes are also common.

Three short adits in black slates comprise workings of the Ohio occurrence. Mineralization observed in dump material consisted of pyrite and lesser chalcopyrite in a gangue of crushed slate, quartz and siderite. Cairnes (1934) reports a fourth adit which could not be relocated. The adits are spaced vertically over about 45 vertical metres, the middle two connected by raises and stopes. The lode is concordant with enclosing slates and variable in thickness from a streak to 3 metres. Some small lenses run oblique to the main lode along tributary fissures. Pockets, disseminations and streaks of tetrahedrite, pyrite, galena and conspicuous chalcopyrite comprise mineralogy.

While no provincial records exist, Cairnes (1934) indicates one shipment of ore in 1909. The shipment was 9.5 tonnes averaging 5485 grams per tonne silver, 2 per cent copper and $4.55 (ca. 1909) in gold (Geological Survey of Canada Memoir 184, page 239).
