- Geological Details
- The showing is located approximately 12 km (7.46 miles) south of the southeastern part of Amisk Lake and approximately 4 km southwest of the Sturgeon Weir River.
The area is underlain by a 50 to 200 ft (15.2 to 61.0 m) thick blanket of Paleozoic sediments covering the Precambrian basement complex. These Paleozoic rocks include the Ordovician Red River Dolomite and a thin (5 - 20') (1.5 to 6.0 metres) 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, projection of units from the exposed Precambrian area to the north and from the diamond drill data.
Rocks 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 camp, a variety of intrusive masses ranging from granitic to ultramafic in composition, and granitic gneisses.
The mineralization in drill hole 229-1 consists of graphite, pyrite, sphalerite, chalcopyrite and minor galena within a weathered to unweathered carbonaceous and graphitic metasediments. The best assay ran 0.92% Zn, 0.03% Cu and 0.06 oz./ton Ag over 1.5 m.

The upper mineralization is hosted in a light to dark grey, slightly foliated, carbonaceous sediment. The lower mineralization is hosted in a light grey, slightly foliated, gray to dark gray, carbonaceous and graphitic sediment which contains earthy pyrite and, locally, up to 20% carbonate laths.
Pyrite and pyrrhotite occur as blebs and as bands which parallel the lamination. There is the odd speck of chalcopyrite and sphalerite present with the other sulphides plus an unidentified silver-gray film-like mineral.

- Exploration History
- 8/11/1988 In 1958, Parmlee Manitoba Mining completed an airborne EM and magnetic survey over the showing area (AF 63L08-0005).
In April of 1976, Aerodat Limited of Toronto flew a combined electromagnetic and magnetic survey of 2,800 line miles (4.506 km) on behalf of Consolidated Morrison Explorations Ltd. of Toronto. Over 90% of the total line mileage was on Permit No. 1. Conductor 229-1 was selected for further ground geophysical investigation. As a result, drill hole 229-1 was drilled in March 1977. Permit No. 1 covering conductor 229 has become CBS 3077 in 1979 (AF 63L08-0016). Recently (as of April 83), the aera over conductor 229278 has lapsed and the ground is now open.
Drill hole 229-1 encountered conductive materials within the regolith zone and continued in conductive materials over 400' (121.9 m). However, core angles were unfavourable averaging about 15° to 20° but varying from 0° to 45°. Conductive materials were mainly graphite, carbonaceous material and earthy pyrite. Some coarse pyrite was present and sphalerite, chalcopyrite and galena were observed by naked eyes.
Between 1986 and 1987, Hudson Bay Exploration and Development completed ground EM and magnetic surveys in the general area.
