The JHC property lies west of Homfray Lake, approximately 4 kilometres southeast of Logan Lake and 35 kilometres north of Merritt.

The property is underlain by volcanic rocks of the Upper Triassic Nicola Group. The area straddles a northwest-trending contact between two volcanic sequences. East of the contact zone are very fine grained, red flows with occasional feldspar (plagioclase?) phenocrysts. The matrix contains moderate amounts of hematite disseminations. To the west are grey volcanics with an aphanitic to fine-grained matrix and associated feldspar and/or augite phenocrysts. Alteration consists of epidote, chlorite and carbonate. The contact zone parallels the main northwest structural trend. Northeast and north trends are also evident. Drilling in 1971 intersected disseminated chalcocite in porphyritic and amygdaloidal basalt.

Fracturing and narrow shears in amygdaloidal andesite contain epidote, carbonate, quartz, malachite and chalcopyrite. A chip sample assayed 4.27 per cent copper and 14.2 grams per tonne silver (Assessment Report 17337).

The JHC occurrence is part of the Bertha property owned by Guy and Christopher Delorme. In 2015, Laurence Sookochoff, working on behalf of the Delormes, carried out a structural analysis and 2 kilometres of localized magnetometer surveying approximately 2 kilometres to the west of the JHC occurrence.
