129. Magnetite.

The deposits of magnetite of the above district are reached by the Central Ontario Railway, built in 1884. From the Coe Hill mine, Lots 15, 16 and 17, Con. VIII., Wollaston, important shipments have been made.

This ore occurs in a series of bodies interbanded with reddish hornblendic gneisses and glistening micaceous and hornblendic schists of Laurentian age. The thickness of what appears to be the highest and most important body has not been ascertained; but the lowest one exposed is about nine or ten feet thick. The deposit was first opened in 1872. In 1891 two roasting furnaces were built which reduced the

sulphur to 0.025 per cent. The operations at the mine were discontinued in 1894. The ore, though generally known as magnetite, contains a considerable proportion of hæmatite.

The following is an analysis of this ore, published in the Report of Progress of the Geological Survey of Canada for 1873-74, p. 208:

Very extensive deposits of bedded iron ores occur in rocks of Cambrian age in various parts of the Labrador peninsula and along the east coast of Hudson Bay. Some of them contain a notable percentage of manganese. They have not yet been worked.

915. Magnetite.

These deposits are situated on the shore of Whycocomagh Bay, at Skye Mountain. The predominating ore is magnetite. The deposits are said to be important. Analyses of specimens made in the laboratory of the Nova Scotia Steel Company gave iron content 49 to 63 per cent. h phorus 0.01 to 0.5 per cent.

From Dickson's location, near Bruce Mines. This location comprises blocks A 1 and A 2, situated on the north side of Desert Lake, and about five miles from Portlock Harbour on Lake Huron. The vein cuts the greyish white Huronian quartzite, is three feet thick, and runs a little north of west and south of east. It has been traced nearly one mile on

the location, and in one place is very advantageously situated for mining. It occurs at an elevation of two hundred feet above Desert Lake, which is connected with Lake Huron by a navigable river, the Thesalon. According to Dr. Ellis of Toronto, the ore contains 56 per cent of iron, and no appreciable quantity of sulphur or phosphorus.

The ore is a compact hæmatite with an admixture of magnetite. The enclosing rock is very varied, consisting of schists, greenstone, and quartzites.

From a deposit known as the "Wallbridge mine." The ore is a finely granular hæmatite, of a steel-grey colour on fresh fracture. In 1880 the Bethlehem Iron Mining Co. commenced operations here, and after extracting about 35,000 tons abandoned the deposit as exhausted in 1883. Since then the mine was again worked by Mr. Coe, with favorable results, but after the extraction of some thousands of tons work was again suspended.

This mine is situated about five miles north of Madoc. The workings consist of an open pit fifteen feet by one hundred feet and forty feet deep. The ore is used at the Hamilton blast-furnace.
