The Bert showing is located in the western head waters of Jim Smith Creek, approximately 2.0 kilometres east of Kiakho Lakes.

The area is underlain by metasediments of the Middle Proterozoic Purcell Supergroup, Creston Formation. The rocks are intruded by rocks of the mid-Cretaceous Bayonne plutonic suite. In addition to the numerous typically granodiorite intrusives representing the Bayonne plutonic suite, much more alkaline syenite and quartz syenite intrusives (stocks and dikes) occur in this area.

Locally, a zone of intense silicification approximately 15 metres wide by approximately 180 metres strike length exposed in outcrop and opencuts. The zone follows the Cranbrook fault, which has thrown Creston Formation rocks into contact with Aldridge Formation sediments, both formations of the Helikian Purcell Supergroup. The controlling fault has a general east strike and steep northerly dip. The brecciated quartzites are intensely silicified with minor quartz veins in which traces of pyrite and gold are reported. A syenite dike has intruded the fault zone from the southwest but has not crossed it. In 1937, Bert group of claims were held by Bert Frisina (Memoir 207, page 51). In 1956, Rimrock Mining Corporation Limited held the area as the Bert group of claims (Annual Report 1956, page 158). In 1957, Rimrock drilled 14 diamond drill holes, averaging 30 metres deep (Annual Report 1957, page 94).

In 1966, Rimrock Minerals completed a 55.7 line-kilometre ground magnetic survey in the area (Assessment Report 895). In 1967, Vanco Explorations completed a 26.0 line-kilometre ground magnetic survey on the area as the Jack claims (Assessment Report 1007). In 1967, Placid Oil completed a program of geological mapping, a 160.0 line-kilometre induced polarization survey and a 33.6 line-kilometre ground magnetic survey in the area (Assessment Reports 1174, 1178). In 1990, a small program of soil sampling and a 0.7 line-kilometre ground electromagnetic survey were completed on the area as the JSL claim (Assessment Report 21335). In 1993, Consolidated Ramrod Gold completed four diamond drill holes, totalling 636.0 metres, in the area (Assessment Report 23135). In 2004, Klondike Gold completed two diamond drill holes, totalling 341.7 metres, in the area (Assessment Report 27764).

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 Bert showings (Figure 8, Assessment Report 34082).
