The Goodenough Central prospect is located 15 kilometres west- northwest of Vernon, north of Naswhito Creek.

In the area, sedimentary and volcanic rocks of the Devonian to Triassic Harper Ranch Group are unconformably overlain by Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks. These units are intruded by Middle Jurassic granitic rocks of the informally named Terrace Creek batholith. Eocene Penticton Group volcanic rocks overlie the igneous and sedimentary rocks.

Altered andesite tuff and cherty tuff of the Harper Ranch Group and diorite host copper, gold and iron mineralization. Most of the mineralization occurs in a calc-silicate altered andesite tuff and comprises stratabound massive to semi-massive lenses of magnetite with disseminated blebs of chalcopyrite and pyrite. Minor bornite, chalcocite, galena and hematite have also been reported. The mineralization, 1 to 7 metres thick, occurs in a tightly folded volcaniclastic horizon. Chlorite, epidote alteration and quartz-calcite veining are common.

Samples from the surface assayed up to 1.45 per cent copper over about 7 metres, although the average grade is significantly lower (Assessment Report 6404). Drill core samples assayed up to about 0.6 per cent copper over about 7 metres; the highest gold value from the skarn zone was 0.6 gram per tonne (Assessment Report 18179).

The diorite is commonly sericitized, silicified and, where proximal to the calc-silicate mineralization, hosts minor disseminated and veined pyrite and chalcopyrite. Copper mineralization is also present in chert or cherty volcaniclastic rocks.

The first reference to the deposit is from 1899; by 1904 there were 8 shafts with depths totalling 47 metres. In 1928-29, Okanagan Copper Co. completed 75 metres of underground workings.

In 1956, New Jersey Zinc Co. carried out a magnetometer survey and stripping. In 1962, Highland Valley Mining Corp. drilled the occurrence. In 1963-64, Empire Development Co. Ltd. conducted geological mapping, soil geochemistry, drilling and magnetometer and self-potential surveys.

In 1969-75, Hudson Bay Exploration and Development Co. Ltd. carried out an induced polarization survey and drilling. In 1977-78, Cominco Ltd. carried out geological mapping and magnetometer and induced magnetometer surveys.

In 1985-88, Brican Resources Ltd. conducted trenching and drilling programs.
