The Kat showing is located on the east side of Lyle Creek, at about 1375 metres elevation. The showing is about 25 kilometres northwest of Kaslo, British Columbia.

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.

No geological information could be found for this showing. The Geological Survey of Canada Open File 464 records this occurrence of unknown character. The commodities silver, lead and zinc are reported. The area covering the Kat showing has received considerable geophysical and geochemical exploration from 1963 to 1970 by D.W. Smellie but no geological description is given. The Kat 13 and 15 Fr. claims received the bulk of exploration work.

The Revenue showing (082KSW058) lies 600 metres to the northwest, along strike and may be of similar character. The Revenue showing is hosted predominantly by slaty, carbonaceous shales and interbedded quartzite and limestone of the Slocan Group. Mineralization at the Revenue showing consists of quartz-calcite- siderite veins with sphalerite, tetrahedrite and argentite.
