This magnetic iron property covers lots 16 and 17, in the third concession, 200 acres, and the mining rights only of lots 125, 126 and 127, concession A, 300 acres, in the township of Lount, Parry Sound district, and is reached by a 14-mile road northwesterly from Sundridge, G. T. R., the owners being the Cramp Steel Company of Toronto. Mining began 8th May 1901, and continued until the end of the year, with an average force of ten, the results being as follows : An open cross-cut 25 feet long by 12 feet wide and 15 feet deep at the face has been driven west into the hillside towards the magnetite body, which is, however, still 10 feet beyond the cut. At 10 feet northwest of this cut an open trench along the ore body was then started and opened to 50 feet in length by 10 feet average width and 12 to 22 feet deep.
The first exploration for iron in Lount township was in 1901 when the Cramp Steel Company, Limited, of Toronto opened up their property in lot 17, concession III, and produced 6,000 tons of magnetite ore valued at S9,000. This is the only production recorded from Lount township.
In 1953, the main pit on the top of the hill was filled with water and plant growth to within 3 feet of the top. The rock types present can only be determined from the broken rock on dumps around the pit. Carter1 gives the dimensions of this pit as 50 feet long, an average of 10 feet wide, and 12-22 feet deep. About 50 feet east of the pit there is an open cut in the side of the hill, 15 feet wide by 100 feet long, which goes westward into the hill with a level floor for 50 feet and then shallows from 15 feet to O feet deep at 100 feet in.
Carter describes this orebody as a north-south lens, about 10 feet wide, consisting, in part, of clean magnetite or mixed magnetite and hornblende. Sulphides were only visible along the walls in irregular patches. Mining began on May 8, 1901, and by January 28, 1902, an ore pile of about 500 tons had been accumulated. The owner at that time was the Cramp Steel Company, Limited, of Toronto.
The country rock is a fine-grained amphibolite. On the dumps, other rocks found include a coarse amphibolite with dark-green hornblende of up to l-inch grain size and interstitial magnetite, pink impure crystalline limestone, hornblende syenite pegmatite, and a granite pegmatite. The largest mass of magnetite found on the dump contained a 6-inch seam of massive magnetite. To the west, hybrid gneisses or migmatites are exposed, and to the north, amphibolite, garnet amphibolite with some massive garnet rock, and crystalline limestone. The occurrence appears to be a small pod, possibly a replacement of a small mass of crystalline limestone. This is not indicated by any anomaly on the Lount aeromagnetic map.
Although this showing is referred to by Carter, and in the Report of the Ontario Iron Ore Committee, as the "Magnetawan" mine, it is not known by that name locally.
