The Ador area is underlain by marine sedimentary and volcanic rocks of the Upper Triassic Stuhini Group.
The Ador showing consists of a strongly silicified shear zone hosted within lapilli tuff. The exposed portion of this shear zone is generally lenticular in shape, varying from one to two metres in width and extending for over 20 metres in length. Pyrite mineralization is found within frothy quartz veinlets along the fractures or as coarse disseminations throughout the silicified rock. The zone, which has a general south-southeast trend and moderate easterly dip, pinches off to the north and is covered in overburden and thick brush to the south. Smaller gossanous pods that are thought to be of the same style of alteration and mineralization, are exposed on the face of the escarpment north of the showing.
A northerly trending fault highlighted by an intense iron-carbonate alteration zone outcrops approximately 30 metres east of the showing. A sample taken in 1989 from a one meter wide zone of silicified, porphyritic volcanics with weak quartz stringering assayed 1.99 grams per tonne gold (Assessment Report 19836).
Work History
In 1980, Du Pont carried out limited geological mapping and prospecting on the property, collecting three rock samples from the area now covered by the Bar 4 claim.
In 1989, Pass Lake Resources Ltd and Golden Sitka Resources Inc. carried out limited geological mapping, prospecting and silt sampling on the Bar 1-8 claims in 1989, taking 20 silt samples and 55 rock samples. The Bowser and Ador showing were discovered.
In September 1990, Pass Lake Resources Ltd and Golden Sitka Resources Inc carried out further geological mapping, prospecting and silt sampling on the Bar 1-8 claims. In total 33 rock and 8 silt samples were collected. Mapping and prospecting was conducted along Dry Creek to find the northern extension of the Bowser showing. Although numerous samples were taken of intense iron-carbonate altered areas and altered dykes, all samples yielded low precious and base metal values.
