The JJ showing is located east of the Apex Mountain Provincial Recreation Area and 2.25 kilometres west of Green Mountain. The property was explored in the early 1970s by New Northcal Mines Ltd. In the mid-1980s, Siemont Resources Ltd. and Brohm Resources Ltd. conducted further property exploration.
The JJ showing is located on the eastern edge of the Hedley Mascot and Nickel Plate mining camp. The general area has been extensively prospected. There is evidence of old hand trenching and bulldozer trenching along a intensely fractured and pyritized zone, exposed along the Apex Mountain Provincial Recreation Area and ski resort access road. A small shaft and a 7-metre adit were discovered in 1985.
Hostrocks of the JJ occurrence are limestone, quartzite and minor altered andesite tuff of the Triassic Nicola Group. These are intruded by fine grained, biotite hornblende granite and granodiorite of the Jurassic Okanagan intrusions and coarse grained, pink granite of the Middle Jurassic Nelson Plutonic Suite. The pink granite appears to be older than the fine-grained granite. These are cut by late granite porphyry and mafic dikes.
At the JJ showing, metasediment rocks of the Nicola Group have been intensely sheared and highly altered to a quartz-biotite-mica schist, with local gneissic phases that form a small roof pendant. The predominant foliation is northeast with a variable steep dip. There are numerous small drag folds. The schists have been cut along the southeast contact by a northeast trending fault zone. The schist is weakly silicified near its faulted contact with granodiorite. At surface, strong oxidation and leaching have occurred. Pyrite with lesser pyrrhotite and chalcopyrite are associated with areas of silicification.
In 1985, a large zone of massive sulphides was located in the vicinity of an abandoned 7-metre adit, south of the Apex Mountain Ski Resort access road. The zone was trenched and sampled over 75 metres width across the structure. Pyrrhotite, pyrite, chalcopyrite and minor bornite were exposed by trenching. Many small fractures and faults contain 5 to 10 millimetre wide quartz veins. Iron-manganese oxide and limonite frequently occur on weathered surfaces and fractures.
The analytical results of samples from pits are as follows: Sample P58 from Pit 2E yielded 4.1 grams per tonne gold and 6.1 grams per tonne silver from fracture containing fault gouge and up to 5 millimetre wide quartz veinlets (Assessment Report 14743). From the same pit, Sample P59 yielded 0.25 per cent copper and 2.4 grams per tonne silver over 30 centimetres (Assessment Report 14743). The sample consisted of siliceous greenstone with up to 40 per cent pyrrhotite, pyrite and chalcopyrite. Three samples from Pit 1E also yielded significant values. Sample P47 yielded 0.18 per cent copper, 0.98 gram per tonne gold and 2.0 grams per tonne silver from 20 centimetres of fault gouge (Assessment Report 14743). Sample P46 was taken over 1-metre of wallrock on the north side of the fault and consisted of siliceous greenstone with 5 per cent disseminated pyrrhotite, pyrite and chalcopyrite. It yielded 0.13 per cent copper, 1.1 grams per tonne silver and 0.29 gram per tonne gold (Assessment Report 14743). From the south side wallrocks, Sample P48 yielded 0.50 gram per tonne gold and 0.03 per cent copper over 80 centimetres (Assessment Report 14743).
