The JO 19 occurrence is located in the northern headwaters of Kelly Creek, at an elevation of approximately 1850 metres on a steep east-northeast–facing slope, approximately 5.5 kilometres north of the north shore of Fable Lake.

The area is underlain by the Permian Cache Creek Group. The Cache Creek Group consists of highly deformed phyllite, chert and argillite with local greywacke and contains discontinuous bodies of carbonate and metavolcanic rocks. Lithologic units of the Cache Creek Group present within the Kelly property are argillite, cherty argillite, limestone, phyllite, tuff, biotite-hornblende feldspar porphyry and intermediate to felsic igneous rocks. The argillite is black, displays banding that may be the original bedding and is well foliated. This unit has very limited outcrop area and appears to occur near units of the felsic to intermediate igneous rocks. The cherty argillite member is grey-black and is frequently interlaminated with chert on a millimetre scale. The cherty argillite displays well-developed foliation parallel or subparallel to the original bedding. The limestone occurs as thinly bedded to massive units hundreds of metres wide in surface exposure and is grey to black in colour, recrystallized, dolomitic in part and probably micritic in origin. The Cache Creek Group units have undergone low-grade regional metamorphism of the greenschist facies.

Mineralization is observed in outcrop from a closely spaced en echelon group of intermediate to felsic igneous rocks and their surrounding sediment. The mineralization is described as a grey fine-grained matrix supporting brown plagioclase and glassy quartz phenocrysts with accessory pyrite.

In 1983, Golden Porphyrite Ltd. conducted a soil and rock geochemical sampling survey on the JO 18-19, 25-26, 33-34, and 42-43 property containing the occurrence. Anomalous gold geochemical values were obtained during sampling, with sample RE-256 of altered iron-rich intermediate to felsic igneous rock yielding 10.2 grams per tonne silver and 0.09 gram per tonne gold and a nearby quartz float sample (RE-0274) assaying 1.8 grams per tonne gold and 13.0 grams per tonne silver (Assessment Report 12543). The rock chip sample B 15 graded 2.6 grams per tonne silver (Assessment Report 12543). Anomalous gold and silver values were observed in soil samples along the border between the JO 18 and JO 19 claims.
