The Jay showing is located about 30 kilometres northeast of Dease Lake.

The showing occurs in a fault-emplaced body of upper Mississippian to Permian serpentinized peridotite of the Cache Creek Complex. This body occurs within a sequence of chert, argillite, argillaceous quartzite, phyllite and greenstone of the Mississippian to Triassic Kedahda Formation (Cache Creek Complex).

The "main showing" is reported to consist of four outcrops of chrysotile cross-fibre in serpentinized peridotite. The cross-fibre ranges from about 1 to 2 millimetres in width. It is reported that the better grade material (2-5 per cent estimated) is confined to a narrow (15 to 30 metre wide) shear zone striking about 029 degrees. Another showing occurs about 600 metres to the east.

It is assumed that the "main showing" as reported in Assessment Report 3363 is the same as the unnamed showing reported by the same company in Assessment Report 3082 as being on the Jay 12 claim.

Totem Minerals Ltd. conducted an airborne geophysical survey (magnetics and electromagnetics) over the area in 1959. In 1967, the Emile claims covered the area of interest and ground magnetic and geological surveys were conducted. Tournigan Mining and Exploration Ltd. with American Smelting and Refining Co. conducted further geological and ground magnetic surveys in 1971.
