The Ophir No. 2 showing is located about 3 kilometres north-northwest of the confluence of Roosevelt and Bitter creeks, 15 kilometres northeast of Stewart.

The area is predominantly underlain by north to north-northeast striking, folded argillites of the Middle Jurassic Salmon River Formation (Hazelton Group) (Bulletin 63). The sediments are cut by several north to northwest trending feldspar porphyry, diorite, andesite and dacite dikes (Assessment Report 20622) that belong to the Portland Canal dike swarm.

A quartz vein occurs on the west contact of a north-northwest trending feldspar porphyry dike. Details on the mineralization are not available but is assumed to be similar to the Morgan No. 6 showing (104A 143) located 640 metres to the southwest or possibly to the Mayou Nos. 1-2 showing (104A 049) located 780 metres to the southeast. At these two nearby occurrences, sulphide mineralization consists of pyrite, galena, sphalerite, chalcopyrite and tetrahedrite.

At the Ophir showing, a chip sample across 10 centimetres assayed 1156.1 grams per tonne silver, 3.52 per cent zinc, 1.78 per cent lead, 0.17 per cent copper and 0.41 gram per tonne gold (Assessment Report 20622).

The Mayou Gold Copper Company acquired a group of claims, including the Ophir No. 2 claim (Lot 5871), north of Bitter Creek in 1928. During 1928-30, the company explored the area. The showing may have been discovered during this time but no work was reported. In 1990, Varitech Resources Ltd. carried out a program of geological mapping, prospecting, sampling and soil, VLF-EM and magnetometer surveys in the area. The showing was sampled at that time. In 2006, a helicopter-borne AeroTEM II electromagentic and magnetic survey was flown over the Silver Cloud property on behalf of Teuton Resources Corp. for a total of 150.0 line kilometres with 100 metre line spacings.
