The Zeus showing, also known as the Wishbone Zone, is located near the headwaters of Palmer Bar Creek, approximately 13.5 kilometres west of Cranbrook.

Regionally, the area is central to the Purcell Anticlinorium, a broad, generally north-plunging structure in southeastern British Columbia. that is cored by Middle Proterozoic Purcell Supergroup rocks and flanked by Late Proterozoic Windermere Group or Paleozoic sedimentary rock. The Purcell Supergroup comprises an early synrift succession, the Aldridge Formation, and an overlying, generally shallow water post-rift or rift fill sequence that includes the Creston and Kitchener Formations and younger Purcell rocks.

The area is within a broad area between the Moyie and Perry Creek Faults that is cut by numerous north-northeast–trending faults sub-paralleling the regional faults. Some zones of isoclinal folding occur along these structures. One of the more significant faults of this north-northeast type is the Palmer Bar Fault, a west-dipping normal fault with 300 to 400 metres of movement on it. Crossing the Palmer Bar and other faults is the east-west– oriented Cranbrook Fault, a north-dipping normal fault juxtaposing Lower Creston rocks against Middle Aldridge. The core of the exploration activity has focused efforts along the Cranbrook Fault on the Bar and Zeus properties. The Zeus mineral potential seems to occur more around the intersection of the Palmer Bar and Cranbrook Faults.

In 2007, the one drill hole to test the Wishbone Zone, close to the intersection of the Palmer Bar and Cranbrook Faults, intercepted a mineralized interval of highly altered, brecciated quartz-feldspar with abundant pyrite and chalcopyrite. This zone is interpreted as an area of highly altered and tectonized sediments replaced by quartz and feldspar (albite) that have been brecciated several times. The best interval returned values of 0.63 per cent copper, 3.8 grams per tonne silver and 87 grams per tonne Bismuth over 57 metres (Assessment Report 29657).

In 2008, diamond drilling intersected 8 metres of silicified breccia with pyrite and local chalcopyrite yielding 0.307 copper over 8 metres and 0.019 per cent cobalt over 91 metres in Hole Z08-1. Another drill hole, Z-07-02, intersected 17 metres of quartz breccia yielding an average of 0.17 per cent copper (Assessment Report 30946).

In 1990, Chapleau Resources undertook an airborne geophysics survey, covering an area west of the Barr property (MINFILE 082FGSW068). In 1996, Abitibi Mining Corp. drilled one hole on the east side of the Barr to test the Cranbrook Fault portion of the Barr mineralization, returning some anomalous gold values. In 2004, Chapleau completed some regional work, covering the Zeus but focused most of their efforts to the east on their Bar option. During 2004 through 2009, Ruby Red Resources completed programs of geological mapping, geochemical sampling, ground electromagnetic surveys and 3 diamond drill holes on the area as the Zeus claims, Purcell Block property.
