The Rob 2(A) showing is about 15 kilometres northeast of Stewart, on Radio Creek, approximately 900 metres north of the confluence of Radio and Bitter creeks.

The area is underlain by generally north striking, folded argillaceous siltstone and intercalated sandstone and pebble conglomerate of the Middle Jurassic Salmon River Formation (Hazelton Group) (Bulletin 63). These rocks are intruded by northwest trending, 3 to 30 metre wide, equigranular and porphyritic diorite and granodiorite dikes. A north-trending fault lies along Radio Creek.

The showing consists of quartz stringers, 1 to 5 centimetres wide, that occur along dike contacts. The stringers contain pyrite, chalcopyrite, sphalerite and galena (Assessment Report 19725). The mineralization is similar to that of the Rob 2(B) showing (104A 145), located about 1070 metres to the south of this showing.

The showing was known probably before 1910, when the Maggie claim group was held in the area by the Crown Mining and Development Company Limited. The company was dissolved in 1918. The showing was covered by the Rob 2 claim, held by A. Kikauka, in 1989. That year Kikauka carried out some geological mapping and prospecting on the claim. The showing was mentioned 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.
