Capsule Geology

The Bear occurrence is located east of Elman Creek, on the western slopes of Little Spider Peak and at an elevation of approximately 1200 metres. The occurrence is described as being located approximately 1200 metres northwest of the Idaho (MINFILE 092HNW007) zone and 450 metres west of the Montana (MIFNILE 092HNW008) zone (Assessment Report 34111).

The area is underlain by an interbedded succession of locally graded siltstone, wacke and coarse volcanic lithic wacke with some discontinuous beds of argillite, volcanic sandstone and conglomerate. These rocks belong to the Early and Middle Jurassic Ladner Group and are in unconformable contact to the southwest and fault contact to the northeast with greenstone, volcanic sandstone and gabbro assigned to the Lower Triassic Spider Peak Formation. Thin, elongate units of brecciated, altered and strongly cleaved, fault-bound slices of greenstone also occur within the Ladner Group. Ultramafic rocks of the Coquihalla serpentine belt occupy the East Hozameen fault to the north.

The Ladner Group sediments have all undergone a complex history of structural deformation characterized by folding. The unconformable contact between the Ladner Group and Spider Peak Formation is locally faulted and sheared.

Locally, as identified by drilling, a carbonate altered zone of interbedded wacke and siltstone hosts pyrite, pyrrhotite, arsenopyrite and minor chalcopyrite. In 2012, a drill hole (BE-01) intercepted 2.44 metres averaging 3.116 grams per tonne gold (Assessment Report 34111).

In 2012, New Carolin Gold completed airborne magnetic and radiometric surveys, totalling 759 line-kilometres, and three diamond drill holes, totalling 220 metres, on the area. The area has been historically explored in conjunction with the nearby Ladner Creek (MINFILE 092HNW007) mine and, more recently, the McMaster (MINFILE 092HNW018) occurrence.
