The Jim 16 showing is located on a small ridge, approximately 2.3 kilometres southwest of Jim Smith Lake.

The area is situated on the eastern limb of a localized, north- plunging anticline within sediments of the Helikian Middle Aldridge Formation (Purcell Supergroup).

Locally, traces of galena are found within Helikian Lower-Middle Aldridge Formation (Purcell Supergroup) sediments near a diorite sill of the Proterozoic Moyie Intrusions. Aldridge sediments strike northwest and dip 10 to 15 degrees northeast. A shaft is present on the showing.

In 1966, Rimrock Minerals completed a 55.7 line-kilometre ground magnetic survey in the area (Assessment Report 895). In 1966 and 1967, Placid Oil completed a program of geological mapping, a 160.0 line-kilometre induced polarization survey, a 113.6 line-kilometre ground magnetic survey, and a 20.8 line-kilometre ground electromagnetic survey in the area (Assessment Reports 863, 1043, 1174, 1207). In 1997 and 1978, Cominco completed a program of geochemical sampling and geological mapping (Assessment Report 6444, 7087).

In 2013/2014, PJX Resources Inc began a large program of gravity and magnetic geophysical surveying to detect dense subsurface features (Assessment Reports 34082, 34937, 35416). The gravity survey extended 10 kilometres beyond the West Basin property claim boundaries encompassing several MINFILE occurrences including the Jim 16 (Figure 8, Assessment Report 34082).
