Capsule Geology

The area is underlain by a Devonian to Permian sequence of sedimentary and volcanic rocks of the Stikine Assemblage that have been intruded by at least three phases of plutonic rocks related to the Coast Plutonic Complex.

Volcanic rocks of probable andesitic composition, appear greyish green in colour and have a slight phyllitic texture. Pervasive, mild propylitic alteration occurs in this unit and silicification, epidotization and pyritization are locally intense.

The southwestern part of the Ian 6 claim is underlain by argillite and meta-argillites that are essentially devoid of texture or bedding. Moderate to strong propylitic alteration is evident as well as bleaching. The argillites are interbedded with buff-coloured, crystalline limestone. Minor development of epidote-garnet-wollastonite skarn occurs within limestone adjacent to an intrusive (refer to Ian 8 - 104B 331).

A hornblende granodiorite intrusive occurs in the western part of the Ian 6 claim. A pyritic intrusion of probable granodiorite composition intrudes the volcanics in the northwestern part of the property. Elsewhere dioritic intrusions occur.

Sulphide mineralization is abundant in the volcanic rocks exposed in the northwestern part of the Ian 6 claim. Pyritization is ubiquitous and chalcopyrite and arsenopyrite occur in quartz veins or stringers within these rocks. In 1987, a sample taken from a pyrite- rich quartz stringer, assayed 2.1 grams per tonne gold and 6.1 grams per tonne silver (Assessment Report 17149).

The most significant gold occurrence found during the course of the 1988 exploration program came from a 5 meter wide gossanous zone in intermediate volcanics, with quartz and minor (3 per cent) disseminated pyrite. Sample 88-VJR-012 taken from this zone, yielded a value of assayed 1.18 grams per tonne gold (Assessment Report 18086).

In 1987, Hi-Tec Resource Management Ltd conducted a reconnaissance exploration program for Vanstates Resources Ltd. This program involved geological mapping, prospecting, soil geochemistry and stream sediment geochemistry (King, 1987).

In 1988, Hi-Tec conducted an exploration program on behalf of Pezgold Resource Corporation on the Ian 6 and 8 claim. A total of 138 rock samples, 332 soil samples and 5 stream sediment samples were taken on the subject property during the course of the 1988 program. A total of 7.2 kilometres of VLF-EM and ground magnetics surveying and prospecting were also completed.
