The Red Rock (Michaely Silver, Big John) occurrence is located on a south-facing slope, north of the Salmo River and east of McCormick Creek, at an elevation of approximately 1000 metres.

Regionally, the area is underlain by quartzites, pelites, phyllites, limestone and argillites of the Cambrian Laib Formation and quartz arenite sedimentary rocks of the Neoproterozoic to Lower Cambrian Hamill Group, which have been intruded by granodioritic rocks of the Cretaceous Anstey pluton to the northeast.

Locally, the area is dominated by bedding plane shears, which have produced what appears as a conformable sequence of sedimentary beds, but are of widely different stratigraphic positions. The sequence has a general trend of 055 degrees with a dip of 65 degree south. A section from south to north, or upslope from the No. 3 to the No. 1 adit, contains a section of Lower Cambrian Laib Formation black phyllites and siliceous grey argillites in fault contact with micaceous quartzites of the Lower and Upper Navada members of the Lower Cambrian Quartzite Range Formation, which in turn are in conformable contact with a thick section of Lower Cambrian Reno Formation micaceous quartzites. Reno Formation quartzites act as structural hangingwall and footwall to Reeves Member limestone (Laib Formation), which is host to the sulphide occurrence. To the north, a second, thinner unit of Reeves limestone, in conformable contact with black phyllites of the upper Laib Formation, acts as the structural footwall to the more northern unit of Reno Formation quartzites.

The main sulphide occurrence is developed on the sheared footwall contact of the Reeves limestone with Reno Formation micaceous quartzites and consists of two bands or lenses of coarsely crystalline galena, sphalerite, high iron sphalerite and pyrite with manganiferous siderite and locally arsenopyrite. The sulphides are shear controlled and partly replace the hangingwall limestone. The mineralized zone is irregular in shape due to folding and faulting with high- and low-grade bands over an average width of 2.44 metres and a maximum width of 6.10 metres within a central, 15-metre long zone that thins out over a total length of 31.09 metres to the west before being displaced by a fault for at least 11.28 metres horizontally to the southeast. The sulphides apparently thin and disappear within 60 metres downdip. The mineralized bands are folded along strike and downdip and are cut by a set of bedding faults and low angle transverse-gravity faults displacing the mineralized zone.

The mineralization differs from the Reeves-MacDonald–type (MINFILE 082FSW026) ore and is apparently more like that found at the Emerald mine (MINFILE 082FSW310). The deposit is primarily lead-zinc with variable amounts of pyrite, but the sulphide proportions vary greatly at different locations. In contrast to other Reeves limestone deposits, the Red Rock occurrence has no dolomite associated with the sulphides. There is little oxidation of the sulphide ores.

Other zones of mineralization are reported north of the main sulphide lens within quartzite, limestone, and argillites and include a 1-metre long or wide zone of sulphides in a grey limestone exposed by a trench approximately 18 metres north of the No. 1 adit portal. Another zone of mineralization, located 11 metres northeast of the previous trench, comprises a galena-bearing shear zone approximately 0.6 metre wide. Galena mineralization is also reported in a sheared black argillite near the face of the ‘A’ adit.

In 1929, a chip sample (983) taken across the vein in an adit assayed 1.4 grams per tonne gold, 259.9 grams per tonne silver, 9.85 per cent lead and 3.2 per cent zinc over 0.69 metre (Property File - C.C. Starr [1929-12-08]: Report of Preliminary Examination of the Red Rock Group).

In 1930, sampling (2207) of the west end an adit yielded up to 697.7 grams per tonne silver, 38.1 per cent lead and 6.7 per cent zinc over 2.1 metres (Property File - C.C. Starr [1930-10-29]: Report of Examination of the Red Rock Group and Adjacent Ground).

In 1946, sampling of the main mineralized lens yielded an average of 304.4 grams per tonne silver, 19.5 per cent lead and 11.2 per cent zinc over a width of 1.29 metres and a length of 10.5 metres (Property File - D.F. Kidd [1947-04-18]: Report on the Michaely Lead-Zinc Mine).

In 1956, the average value of outcrop samples over a 1.23 metre width was reported as 328.3. grams per tonne silver, 20.7 per cent lead and 14.3 per cent zinc, whereas sampling of the No. 1 and 2 adits yielded an average of 106.0 and 246.2 grams per tonne silver and 7.4 and 25.3 per cent lead with 7.4 and 17.1 per cent zinc over 0.93 and 1.23 metres, respectively (Property File - M.M. Botorac [1956-07-03]: Report on the Michaely Property).

In 1959, a chip sample across 1.0 metre from a zone exposed by a trench approximately 18 metres north of the No. 1 adit portal assayed 3.8 per cent zinc, 0.49 per cent lead and 10.3 grams per tonne silver, whereas four grab samples from the Red Rock mine averaged 0.14 per cent copper, 5.65 per cent lead, 11.39 per cent zinc, 205.2 grams per tonne silver and 0.125 gram per tonne gold (Assessment Report 10225).

In 1981, channel samples, over 0.5 metre, from four trenches yielded values up to 0.11 per cent copper, 4.6 per cent lead, 3.3 per cent zinc and 539.3 grams per tonne silver (Assessment Report 10225).

In 1993, combined underground channel sampling and minor diamond drilling indicated an ore reserve of 51 710 tonnes grading 4.59 per cent lead, 8.53 per cent zinc, 0.05 per cent cadmium and 87.2 grams per tonne silver, including a high-grade core of 20 865 tonnes grading 6.13 per cent lead, 11.71 per cent zinc, 0.015 cadmium and 115.6 grams per tonne silver (Assessment Report 22901).

From sporadic production in 7 years between 1935 and 1979, a total 525 tonnes of ore were mined yielding 154 738 grams of silver, 155 grams of gold, 16 kilograms of copper, 85 059 kilograms of lead and 94 987 kilograms of zinc. The high proportion of silver indicates a high temperature epigenetic manto-type replacement deposit.

This property was staked in 1928 and has been held by the present company since 1932. Workings comprising four adits—Nos. 1, 2, 3, and the ‘A’ adit, driven approximately 8, 46, 69 and 15 metres, respectively—and several trenches were completed prior to 1937. Adits No. 1, 2 and 3 were driven to develop the main mineralized zone, and the ‘A’ adit and many of the trenches were made to explore other showings a little to the north. In No. 2 adit, the zone, containing up to 2 metres of massive sulphides, was encountered approximately 30 metres in from the collar and approximately 23 metres down dip (60 degrees east) from its surface outcrop. In No. 3 adit, what is thought to have been the limestone-quartzite contact was encountered approximately 87 metres from the collar and 34 metres below No. 2 adit. The zone here was barren, however Fyles and Hewlett, (1959, p. 139), state: "The compass survey indicated that No. 3 adit may lie east of the projected position of the ore lens, but more accurate information on the rake of the ore is required".

Between 1937 and 1947, the property was idle. In 1947, 62.6 tonnes of ore were shipped and in 1948 a raise was driven in ore from No. 2 adit to the surface. In 1948 and 1949, additional shipments of ore were made; however, since that time little work has been done. The collars of three diamond drill holes can be seen near No. 3 adit, but the results of this drilling are not known. In 1956, Canadian Exploration Ltd. examined the property.

In 1978, Swift Creek Mining staked the area as the Big John claim and the following year a 12-metre raise was reportedly driven from the No. 3 adit level. In 1981, Greenwich Resources Inc. completed a program of geochemical (rock, silt and soil) sampling, geological mapping and ground geophysical surveys on the area as the Red Rock property.

During 1988 through 1990, International Corona Corp. completed programs of soil and silt sampling, geological mapping and a 2660.0 line-kilometre airborne geophysical survey on the area as the Elise 1-61 claims. In 1992 and 1993, Jopec Resources completed programs of underground rehabilitation, geological mapping and sampling, soil sampling and 14 diamond drill holes, totalling 276.2 metres, on the area.

During 2007 through 2013, Clarke Gold Inc. conducted programs of geological mapping and soil, silt, heavy mineral and rock sampling on the surrounding area as the Nox Fort property. In 2013, the area was prospected and rock sampled as the Michaely project.
