In the Cabin showing area, disseminated chalcopyrite occurs as 1-millimetre grains hosted by a subgreywacke unit and quartzitic sandstone of the Helikian lower Sheppard Formation (Purcell Supergroup). Disseminated sulphides are noted in close association to small normal faults which have little offset. Mineralization occurs immediately below (about 12 metres) a marker horizon of stromatolitic dolomite of the upper Sheppard Formation. The stromatolitic dolomite is also host to mineralized, quartz-filled fractures up to about 1 metre above the basal contact with the underlying mineralized clastic sediments. Sericite alteration is distinctive in mineralized areas. Quartz veins may contain chalcopyrite, barite, specular hematite, and/or minor sphalerite but the veins are generally narrow and poorly mineralized.
WORK HISTORY
In 1989, Teck Exploration Ltd. (Teck), conducted exploration activities on the Roo 1-3 claims (which were staked by, and under option from, Equity Engineering Ltd.). The work conducted is within the current Robocop Property. The program consisted of mapping, soil sampling (114 samples) and eight backhoe trenches (totalling 250 metres) aimed at evaluating sediment hosted copper-silver-cobalt showings (Assessment Report 19898; Assessment Report 22644). Three samples were collected about 500 metres northwest of the Wolf showing (082GSE009).
The 2007 rock sampling program (70 samples) of Ruby Red Resources Inc. focused on mineral occurrences in the Phillips Creek area. The main copper-cobalt showings on the property are located within the Roo Horizon but the sampling program uncovered mineral showings within quartzites and stromatolites above the Roo Horizon and in volcanic stratigraphy below the Roo Horizon. The soil sampling program consisted of three lines of contour soil samples with the majority of the sampling conducted within the current property. The second line, running, northwest to southeast, showed a significant anomaly running over a kilometre in length with values up to 313 parts per million copper (Assessment Report 29941). This second line was between Phillips Creek and the showings of Wolf (082GSE009) and Cabin (082GSE010) showings to the north. The third soil sample line showed a moderate anomaly, trending over 700 metres, and is potentially related to the Miller Creek showing in the vicinity. The 2007 trenching program by Ruby Red Resources was designed to re-assay the Roo showing and assess the style of mineralization. Five historic trenches were reopened, and Trench number 5 was noted to display copper-bearing barite veins. All trenches to date have been completed in the same vicinity and lie within the current property (Figure 2). Sampling was done at/near Green (082GSW019), Roo (082GSW020), Phillips Creek (082GSE001), Wolf (082GSE009), and the Miller Time (082GSW093) showing on the northern slopes of Miller Creek. Mapping and sampling occurred on the southeast trending roads that are north and south of Wolf and Cabin showings.
The 2021 exploration program of Grizzly Discoveries Inc. on the Robocop property consisted of rock and soil sampling, geologic mapping, and an airborne magnetic and electromagnetic geophysical survey (Assessment Report 39963).
