Point Location Description: Stripped areas, pits.
Location Method: Conversion from MDI
Access Description: The occurrence is located in Priske Township on the northeastern shore of Cook Lake about 2.4 km north of Schreiber (claim TB1048, claim map G-631, Priske Township). Access may be gained using a bush road which extends north and east of Schreiber to Cook Lake. The property adjoins the northeast portion of the lake.
Circa 1900: Mining Locations X776 and X777 were staked by J.E. Walker, S. Otisse and J.D. Mudge, all of Schreiber. Some stripping and test pitting was undertaken. 1900: The property was visited by J.A. Bow, Inspector of Mines. 1907: E.L. Fraleck investigated the 'Otisse Prospect' for his report on iron pyrites in Ontario. 1909: J.D. Mudge staked TB 1048, formerly the northwest part of Mining Location X776. 1910: Surface work continued for assessment credit. 1915: A patent was approved for TB 1048. 1938: G.A. Harcourt of the Ontario Department of Mines examined and sampled the property. 1952: Claim ownership was transferred for taxes to E. Mudge Graham. 1981: TB 1048 became part of A.J. Garity Estate. 1987: J. Bond and D. Christianson conducted some stripping, prospecting and sampling on the Cook Lake occurrence located 0.75 km northeast of the Mudge occurrence.

Dec 07, 2005 (B Nelson) - The occurrence is first described by Bow (1901 p.89): The sulphur, or pyrites, deposit consists of a mineralized zone with an oxidized capping outcropping along the hillside where the rock is more or less exposed. It is said to be traceable for over a mile (1.6 km), with a strike of nearly east and west. We walked along it for several hundred feet examining exposures which occurred at intervals. Test pits have been sunk at several points, and a couple of these were inspected. The deposit is heavily impregnated with pyrite on the surface, and lower down the percentage of the mineral increases, until it occurs in almost solid masses. There is said to be a solid body several feet wide at bottom of the pit, but water prevented examination. The dump looked very encouraging. Harcourt (1939 p.28) adds that: A polished section of sulphides from a pit 15 chains (990 feet; 302 m) from Hollinger Lake revealed pyrrhotite evenly distributed through an andesitic rock in such a way as to form a graphic pattern. There is a considerable amount of magnetite associated with the pyrrhotite in the sample.

Dec 07, 2005 (B Nelson) - Pyrrhotite occurs in masses or veins in the deposit, but it is not mixed with the pyrite. A heavy fahlband (band of sulphide mineralization in a (schistose) dark metamorphic rock) strikes east for about a mile (1.6 km). The gossan capping had in several places been removed and test pits sunk. The largest of these was about twelve feet (3.7 m) deep and twelve feet (3.7 m) long across the strike of the deposit, which is here seen to consist of a very fine grained mixture of pyrite, pyrrhotite and silica. An average sample of the dump yielded 32.26 per cent of sulphur. (Fraleck 1907 p.177).
