Point Location Description: Trenches.
Location Method: Conversion from MDI
Access Description: The occurrence is located along the Little Bear Quarry Road (Camp 81 Road) off Highway 17 and about 19 km east northeast of Nipigon in Patience Township (claim map G 142). The occurrence is approximately 4.2 km northeast along Little Bear Quarry Road (Camp 81 Road) which departs Highway 17, 19 km east of Nipigon. The showing is 150 m west of this point on the road, however, mineralization can be found on both sides of the Little Bear Quarry road (Camp 81).
Circa 1929: Trenches were dug on the occurrence by H.M Lewis, L.T. Seyler, J. Lawrence and D. Conner. 1983: J. Hakala of Nipigon held claim TB 658036 over the occurrence.
Province: Superior
Geological Age: Archean
Dec 07, 2005 (B Nelson) - Hawley (1929) described the Kama Hill occurrence: The main vein system occurs on claims Nos. 7492 and 7493 and strikes approximately east, dipping vertically. It has been uncovered chiefly along a terrace in the sediments, a short distance below the diabase sill. It may be traced for approximately 800 feet. At the east end the vein consists of 6 inches of calcite lying in red cherty dolomite and carrying specks of sphalerite. Five chains to the west it widens to 12 inches and there lies in brecciated chert. It contained some quartz with dark sphalerite and small cubes of galena. A second 8 inch vein lies 3? feet to the south and consists of barite with sphalerite and galena. This vein widens to 2 feet a short distance to the west. Towards the west a stockwork of small quartz and barite veins occur in the dolomite and strikes W 15?N (285? azimuth). These veins have similar sulphides but are only from 1 to 3 inches wide. The vein system occurs in a shear or fault zone partially in a dry creek bed which is flooded in the spring. The vein, which pinches and swells considerably, varies from about 0.6 m (2 feet) to about 7.5 to 10.0 cm (3 to 4 inches) in width and varies in strike from about 105? to 140?. The dip is 60? to 70? to the south. The vein can be traced for approximately 30 m (100 feet) to the west where another vein or the extension of the same vein occurs as massive barite 0.6 to 0.75 m (2 to 2.5 feet) wide. Here the vein is not mineralized with sphalerite or galena to any great extent. This portion of the vein can be traced for a further 9 m (30 feet). The host rocks in the vicinity of the main showing vary from a pink quartz feldspar granite to a quartz porphyry granite. The granite also appears gneissic in places.

Dec 07, 2005 (B Nelson) - Sp and gn, with calcite and quartz gangue, occur filling a fault zone in Sibley dolomite. The vein is mineralized with sp and gn with minor malachite stain and chalcocite. Some cp occur along with the sp (J. Hakala, personal communication). Fluorite also occurs in conjunction with the barite. Calcite in the vein is minor compared to barite. The sp appears to occupy discrete pods of almost massive zinc whereas the gn is less abundant and more widely distributed throughout the vein. The barite occurs as large platy crystals and is pinkish-beige in colour. Fluorite and amethystine quartz occur as accessory minerals. Samples taken by Resident Geologist personnel returned vaues including: 83-BJH-1: 1.62 oz/ton Ag, 3.76% Pb, 19.7% Zn (from barite-quartz vein with massive sp, and some gn). 83-BJH-2: <0.10 oz/ton Ag, 3.04% Pb or 1.73% Zn (from quartz vein material with good gn). 83-BJH-4: <0.10 oz/ton Ag, 5.16% Pb, 800 ppm Zn (from alteration zone).
Dec 07, 2005 (B Nelson) - An alteration zone occurs in association with the main mineralized zone. The alteration zone consists of altered granite which is epidotized and sericitized. On both sides of the altered zone is about 0.6 to 0.75 cm of pure barite.
