The Line showing is located on the shore of a tiny lake on the upper north slopes of Mount Baldy, a few kilometres east of Little Fort. The property area covers the western Cretaceous Baldy batholith and volcanic and sedimentary rocks of the Devonian to Permian Fennell Formation (Slide Mountain Group). The old Windpass mine (092P 039) is three kilometres to the southwest.

At the Line showing, galena, sphalerite, chalcopyrite and pyrrhotite occur within a narrow quartz vein within a north striking shear zone and is exposed in a trench. Coarse grained, patchy base metal sulphides occur, along with quartz, as matrix in a breccia. Pyrrhotite is disseminated and carbonate is present on fractures. Thin and medium bedded, bleached and silicified quartzites immediately east of the mineralization strike northeast and dip 45 degrees southeast. The mineralized quartz vein and enclosing shear zone strikes north-northeast and dips steeply to the east. An aplite dike crops out 15 metres east of the trench; it appears to be parallel to the mineralized zone.

The area was staked as the Judy Group of claims and was mapped in 1965 by Quebec Cartier Mines. Darkhawk Mines staked the area as the SS claims and ran a geochemical soil survey of 555 samples in 1971. Cominco Limited conducted geological mapping and a soil geochemistry survey in the area in 1980. The area was staked as the Kog claims in 1990 by F.P. O'Grady and Peter Klewchuk. They ran a program of prospecting, geochemical sampling and geological evaluation that summer. O'Grady and Klewchuk renamed the Line as the Lake showing, and they renamed the nearby Judy 4 (092P 036) as the Cliff.
