The Morgan No. 6 showing lies 1 kilometre northeast of the peak of Ore Mountain, on the ridge that runs from Ore Mountain to Radio Mountain, 15 kilometres northeast of Stewart. The upper adit is in the south-central part of the Morgan No. 6 claim (Lot 5862).

The area is underlain by north to northeast striking, folded argillites and siltstones of the Middle Jurassic Salmon River Formation (Hazelton Group) (Bulletin 63). The sediments are cut by several north to northwest trending quartz diorite and granodiorite dikes that belong to the Portland Canal dike swarm.

Mineralization lies along a north-northwest trending fault that dips 70 to 80 degrees east. A north trending granodiorite dike lies a few metres to the east of the fault. The fault system is marked by a rusty fracture zone containing quartz lenses and pods; the system can be traced for about 100 metres. Two tunnels have been emplaced along the footwall of the fault: a 29 metre long upper tunnel and a lower tunnel, 46 metres south and 30 metres below the upper tunnel. In the upper tunnel, the vein averages 27 centimetres in width and can be traced for 24 metres before it pinches out. Mineralization consists of highly oxidized vein material carrying limonite, smithsonite, cerussite, pyrite, galena, sphalerite and tetrahedrite.

The weighted average of two channel(?) samples collected in 1984 from the portal of the upper tunnel, representing a vein width of 32.5 centimetres, is 6411.5 grams per tonne silver, 1.5 grams per tonne gold, 23.2 per cent lead, 4.4 per cent zinc and 0.9 per cent copper (Assessment Report 13352). The weighted average silver grade over an average width of 27 centimetres for a length of 20.7 metres of the vein in the upper tunnel is 6941.9 grams per tonne (Assessment Report 13352).

The best channel sample from the lower tunnel assayed 116.9 grams per tonne silver, 0.3 gram per tonne gold, 1.4 per cent lead, 1.05 per cent zinc and 0.18 per cent copper across a width of 2.9 metres (Assessment Report 13352).

About 200 metres south of the lower tunnel, on the Morgan claim (Lot 5881), a quartz vein is associated with a northwest-trending dike. The vein pinches and swells and is exposed on the east wall of the gulch. The vein carries pyrite, galena and minor sphalerite and chalcopyrite. A channel sample, taken in 1984 across the 30 centimetre wide vein, assayed 172 grams per tonne silver, 0.75 gram per tonne gold, 5.1 per cent lead, 0.28 per cent zinc and 0.10 per cent copper (Assessment Report 13352).

The Mayou Gold Copper Company acquired the Morgan claim group in 1928. During 1928-30, three adits and several opencuts were emplaced on the mineralization on the Morgan No. 6 claim. In 1929, 2.1 tonnes were shipped from the Mayou property, presumably from the Morgan No. 6 showing. This ore produced 1 gram of gold, 7246 grams of silver, 432 kilograms of lead and 602 kilograms of zinc. The claims were subsequently acquired by Rufus-Argenta Mines, 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 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. he prospect 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.
