The H & H copper showing occurs on Hines Creek, 1.1 kilometres southeast of the creek's confluence with the Tulameen River and 7.5 kilometres west-southwest of Tulameen.

The occurrence is hosted in hornblende clinopyroxenite of the Early Jurassic Tulameen Ultramafic Complex, a zoned Alaskan-type intrusive complex. The showing lies immediately west of the contact with metamorphosed volcanics and sediments of the Upper Triassic Nicola Group.

Medium to coarse-grained, black hornblende clinopyroxenite, comprised of augite and hornblende with minor biotite and magnetite, outcrops over a 5 by 4 metre area 5 metres east of the creek. The clinopyroxenite is cut by a pegmatite zone 0.9 metre wide containing hornblende crystals up to 5 centimetres and minor interstitial feldspar. The zone strikes 010 degrees and dips 70 degrees east.

Stronger mineralization is present in the pegmatite, which contains up to 20 per cent patchy disseminated pyrite and up to 2 per cent disseminated chalcopyrite. The surrounding clinopyroxenite contains up to 20 per cent disseminated pyrite and trace chalcopyrite, in bands to 3 centimetres wide. A grab sample of pyroxenite, with 10 per cent interstitial pyrite and malachite staining, analysed 3.603 per cent copper, 0.066 gram per tonne gold, 17.1 grams per tonne silver, 0.247 grams per tonne platinum and 0.730 grams per tonne palladium (Assessment Report 17280, page 9, sample W461).

A quartz vein, up to 10 centimetres wide, outcrops 50 metres to the south. A grab sample of the vein assayed 0.810 gram per tonne gold and 0.025 grams per tonne platinum (Assessment Report 17280, page 9, sample W637).

The copper showing was discovered in 1987 by North American Platinum Corporation while exploring for platinum in the Tulameen Ultramafic Complex.
