The Reb showing is located on a south-facing slope, west of the Ospika River in the northern Rocky Mountains, approximately 50 kilometres east of the northern end of Williston Lake and approximately 137 kilometres north of Germansen Landing.

Hostrocks are graphitic black shale, siltstone, limestone, dolomite, sandstone and shale of the Middle Ordovician to Middle Devonian Road River Group, which is abnormally thick in the area, possibly due to deposition in a third-order basin (Assessment Report 10831). Cambrian to Ordovician phyllitic, nodular mudstone of the Kechika Group is in fault contact to the east and Silurian and Devonian carbonate and fine clastic rocks are in unconformable contact to the west. Strata on the claims are overturned and strike northwest, dipping steeply east.

Locally, a 30- to 40-metre-wide zone of pyrite interbedded with black shale, commonly siliceous, and black chert host massive pyrite bands spaced 1 to 2 metres apart, varying from less than 1 centimetre to 1.0 metre wide and commonly with 0.3-metre-wide massive sections. The pyritic horizon has been discontinuously traced for approximately 300 metres along strike. Although outcrop is poor, mapping and hand trenching suggest that the pyrite is stratigraphically underlain by sediments containing nodular, disseminated and layered pyrite and chert as well as quartz and barite veins that carry minor chalcocite, chalcopyrite, malachite, azurite and tetrahedrite.

In 1980, a rock sample (9970) assayed 0.23 per cent lead, 32.08 per cent iron and 7.2 grams per tonne silver, whereas a rock chip sample from an outcrop of travertine and limonite located approximately 2.6 kilometres to the southeast of the occurrence assayed 1.57 per cent zinc (Assessment Report 8621).

In 1982, a sample of limonite-stained shale from bedrock or talus exposed in trench 13 at a depth of 1.5 metres assayed 1.5 per cent lead and 0.26 per cent zinc, whereas a grab sample of a copper-stained quartz vein assayed 0.3 per cent copper (Assessment Report 10831).

In 1994, chip sampling (133944) of massive pyrite from the Reb occurrence yielded up to 0.149 per cent lead and 4.4 grams per tonne silver over 1.0 metre, whereas a chip sample of black chert in the hangingwall of the massive sulphide horizon yielded 0.286 per cent copper over 1.5 metres (Assessment Report 23644). A sample (133957) of quartz-carbonate vein with malachite, azurite, chalcopyrite, sphalerite and tetrahedrite, taken upslope of the occurrence, assayed 1.88 per cent copper, 0.131 per cent zinc, 0.577 per cent antimony and 252.3 grams per tonne silver (Assessment Report 23644). Also at this time, trench 94-14 (samples 133960 through 133962), located several hundred metres to the west-northwest of the previous samples, yielded an average of 0.311 per cent lead with 15.6 grams per tonne silver over 3.8 metres of laminated and remobilized ferricrete, whereas a rock sample (133948) of ferricrete near chert, located several hundred metres further west, yielded values of up to 1.77 per cent zinc and 16 grams per tonne silver (Assessment Report 23644).

In 2017, four rock samples (DT17-001 through -004) from the massive pyrite horizon yielded from 0.118 to 0.361 per cent lead with 3.0 to 7.2 grams per tonne silver (Assessment Report 37255).

Work History

In 1979, Esperanza Explorations conducted a prospecting program discovering the showing. In 1980, Esperanza optioned the Reb property to Esso Resources. During 1980 through 1982, Esso Resources undertook an exploration program consisting of prospecting, geological mapping, geochemical sampling (1000 soil and rock samples), some trenching and stream sediment heavy mineral sampling.

In 1994, Teck Exploration Ltd. conducted a work program comprising soil (216), rock (32) and stream sediment (7) sampling. They also completed detailed structural mapping and sampling in the vicinity of the showing and ferricrete zones along strike, and minor hand trenching. This work extended the known lead-in-soil anomaly to approximately 1.7 kilometres along strike with values of up to 7570 parts per million lead, 3725 parts per million zinc and 25.2 parts per million silver (Assessment Report 23644).

In 2008, Takara Resources Inc. acquired the Ospika property claims, which covers the Reb showing, through an option agreement with the owner, S. Wetherup. In the same year, Takara Resources conducted reconnaissance and prospecting work (2 samples). In 2017, Commander Resources Ltd. completed a program of geological mapping and geochemical (rock and soil) sampling on the Rebel property.
