The Where Northeast showing is 2.0 kilometres south-southwest of the summit of Selish Mountain and 4.1 kilometres west-northwest of the confluence of Howarth Creek and its main east-flowing tributary. A similar occurrence, Where Southwest (092HNE135), is 460 metres southwest.

A zone of skarn alteration and associated mineralization is developed in hornfelsed andesite in the Western volcanic facies of the Upper Triassic Nicola Group, about 100 metres southeast of a Triassic-Jurassic dioritic to gabbroic stock that underlies much of the south flank of Selish Mountain.

The zone outcrops over an area 12 metres long and 8 metres wide. The skarn is composed of alternating bands of calcite, epidote and burgundy red garnet, striking 020 degrees and dipping 15 to 20 degrees northwest. It contains abundant specular hematite, as massive seams parallel to banding, as disseminations and as massive rosettes. A 1-centimetre thick seam of malachite is also present, and parallels banding. A considerable amount of disseminated chalcopyrite occurs through the skarn. Overall copper content is estimated at 0.2 to 0.3 per cent (Assessment Report 4677, page 9). A channel sample assayed 0.44 per cent copper and 6.2 grams per tonne silver over 0.76 metre (Assessment Report 4677, Map 4).

Work History

In 1966, T.C. Exploration Ltd. completed a 67.2 line-kilometre airborne magnetic survey on the area immediately west of the occurrence as the Doe, Gay, Kane and Salem claims.

The showing was mapped and sampled by El Paso Mining and Milling Company in 1973.

In 2014, Tech-X Resources Ltd. completed a program of geological mapping and geochemical (rock and soil) sampling on the area as the Selish Mountain property. A rock sample (7635) from a historical trench exposing banded skarn yielded 0.102 per cent copper (Assessment Report 35197).

In 2019, Lionheart Exploration Inc. completed a program of geological mapping and geochemical (rock, silt and soil) sampling on the area as the Chev property.
