The Radio No. 3 showing is located about 14 kilometres northeast of Stewart, on a small creek on the north side of Bitter Creek, approximately 1.8 kilometres east of Ore Mountain. The showing is located in the south-central part of the Radio No. 3 claim (Lot 4574).
The area is underlain by north to 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 dikes that belong to the Portland Canal dike swarm.
Two occurrences are exposed in the canyon of the creek. Both lie on the west wall and are hosted in fractured and sheared argillite that is intruded by several small dikes. The upper showing is an east-southeast trending, vertical, 50 to 75 centimetre wide quartz vein. The vein contains disseminated galena, sphalerite, pyrite and minor chalcopyrite. The vein is hosted in argillite near a narrow, northwest-trending dike and is exposed for a length of 15 to 20 metres. A well mineralized grab sample assayed 4.39 grams per tonne gold, 208.4 grams per tonne silver, 0.6 per cent zinc, 0.62 per cent lead and 0.13 per cent copper (Assessment Report 13352).
The lower showing is about 40 metres below the upper one. It comprises a 10 metre wide stockwork zone of quartz, sphalerite and galena in shattered argillite. The zone can be traced for about 30 metres up the canyon wall. It apparently terminates against an east- trending dike near the top of the exposure. A grab sample collected in 1984 assayed 0.55 gram per tonne gold, 37.4 grams per tonne silver, 0.92 per cent zinc, 0.44 per cent lead and 0.24 per cent (Assessment Report 13352).
The early history of the showing is not clear. Crown Mining Company held ground in the area before 1910 (Geological Survey of Canada Map 28A). According to early records this company held both the Swede American and Maggie claim groups in the area. The Bitter Creek Mining Company held the White Mike and Cuprum claim groups. Exploration work, including tunnelling, was reported on both the Crown Mining and Bitter Creek Mining properties in 1910-11. In 1923, Erickson and Peterson restaked the area (White Mike and Cuprum groups?) as the Radio claim group. Radio-Stewart Mines was formed in 1924 and acquired the Radio claims. Intermittent prospecting and opencutting were done during 1925-29. An old tunnel, about 25 metres long, was reported on the showing in 1928; presumably, this tunnel was driven in 1910-11. The Radio claims were Crown granted to the company in 1930. The claims were subsequently acquired by Rufus-Argenta Mines Limited, formed in 1955. In 1966, the company name was changed to Crest Ventures Limited. During 1966-67, Crest Silver Company Limited, a subsidiary of Crest Ventures, acquired the claims and carried out some geological mapping. During 1970-73, Ardo Mines Ltd. optioned the property and carried out prospecting, magnetometer and electromagnetic surveys. During 1979-80, Beaver Gold Resources Inc. acquired the property in 1979 and carried out mapping, prospecting and sampling. No further work was reported on the showing until 1984 when the property was owned by Grey Silver Mines Ltd. That year Maralgo Mines Limited optioned the property and flew an airborne VLF-EM and magnetometer survey over the area and conducted geological mapping, prospecting and sampling on the occurrence. No more work was reported until 1989 when Grey Silver Mines performed geological mapping, sampling and soil surveys in the area. The following year Varitech Resources Ltd. conducted a program of geological mapping, prospecting, sampling and soil, VLF-EM and magnetometer surveys in the area. The showing was resampled that year. 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.
