- Geological Details
- The showing consists of a single drill hole (565-1) completed to intersect an EM and magnetic anomaly.
The area of the showing is underlain by a thick blanket of Paleozoic sediments 50 to 200 ft (15.2 to 61.0 m) thick covering the Precambrian basement complex. The Paleozoic rocks include the Ordovician Red River Dolomite and a thin (5 to 20 ft (1.5 to 6.1 m)) basal layer of Ordovician Winnipeg sandstone. A regolith zone is generally present at the top of the Precambrian section.
The Precambrian geology can be interpreted only from the geophysical data, from projection of the units from the exposed Precambrian area to the north and from diamond drill data. Rock types known to occur beneath the area include a wide variety of volcanic rocks with associated pyroclastic and argillaceous units (all correlative with the Amisk Group which hosts all of the Cu-Zn deposits of the Flin Flon area), a variety of intrusive masses ranging from granitic to ultramafic in composition, and granitic gneisses.
The drill hole intersected a sequence of highly altered meta-volcanics which include hematized andesite, dacite, a chloritized coarse tectonic breccia with fragments of rhyolite and andesite, and intensely hematized and brecciated mafic to intermediate tuff. The interval 357.0 to 398.0 consists of a mineralized graphite-earthy pyrite schist. This schstose interval, when assayed, returned assay values of 0.06 to 0.08% Cu, 0.01% Zn, 0.03 to 0.04 oz./ton Ag and 0.02% Ni.

The mineralized sedimentary horizon in this hole is identical to that in nearby drill hole 566-1 and it is similar to the sequence of sediments found at the nearby Westarm Mine. The metasediment is best described as a foliated, black, soft, locally laminated black earthy pyrite-graphite schist to argillite to slate which contains finely disseminated pyrite.

- Exploration History
- 4/25/1989 The showing was located as a result of a combined electromagnetic and magnetic survey flow over the area in 1976. The surveys were completed over 133 miles (214 km) and CBS 3055 was subsequently staked.
Conductor 565 was selected as a result of these surveys. One diamond drill hole (565-1) was completed on the conductor in late 1977 (AF 63L08-0016). The drill hole returned the results listed above.
The land was restaked as MPP 1134 by SMDC.
