The Eight occurrence is located approximately 3.5 kilometres east of the Sustut River and 8 kilometres south of Willow Creek (Assessment Report 4892).

Regionally, the area is underlain by Upper Triassic Dewar Formation (Takla Group) sediments, which are bounded to the south by a northwest trending fault. Upper Triassic Moosevale Formation (Takla Group) volcanics occur across the fault. Locally, a dioritic intrusion cuts black cherty siltstones and grey tuffaceous wackes.

Four calcite-quartz veins, containing sphalerite and minor chalcopyrite, are associated with these rocks. At the plotted MINFILE of the Eight occurrence location, chrysocolla, chalcopyrite and pyrite disseminations are found near the contact between the pyroclastics and the banded cherts. Nearby, silicified and quartz veined rocks contain disseminated chalcopyrite and pyrite. Approximately 500 metres to the south, chalcopyrite and pyrite are disseminated in a crystal tuff near an east-southeast striking fault.

Three major soil anomalies can be distinguished from Westfrobs 1973 soil sampling. One each on the east and west sides of the soil grid and a third one on the north end. The anomaly in the north is best expressed by the high silver values enforced by isolated anomalous values of all other elements. The other two areas show anomalous values for all elements checked. None of the anomalous areas seems to be directly related to the intrusive contact and all of them could be attributed to the scattered quartz-calcite-sulphide veins found on the property.

In 1973, Wesfrob Mines Limited completed a soil geochemical survey on their Pat claims (094D 074), collecting 242 soil samples.

The Tie 1-48 and Jan 85-112 claims were purchased by Vestor Explorations Ltd. from W.H. Hudson of Vancouver in April 1973. Between August 18th and August 26, 1973, a crew of four geologists and three assistants from Vestor Explorations Ltd. conducted a program of geological mapping and stream sediment sampling on the Tie and Jan claim groups adjacent the Pat claims of Westrob Resources. Some limited prospecting was carried out in the course of traverse geological mapping and 9 minor copper occurrences were discovered. About 200 stream sediment samples and a limited number of soil samples were obtained. Only 5 rock samples were collected.

In 1974, a combined magnetic and electromagnetic survey 640 kilometres in total length was completed on behalf of Rio Tinto (Assessment Report 4921). Several high conductivity anomalies were recommended for follow-up. The Rio Tinto survey encompassed the following MINFILE showing areas: TJ (094D 050), Park 2 (094D 052), East Ridge (094D 053), Pond (094D 054), Red Copper (094D 055), Eight (094D 074), Pluto (094D 075), Tie (094D 089), A462 (094D 102). The southern boundary of the survey may actually be farther north.
