CHROMITE (Chromic Iron Ore).

The Canadian deposits of chromic iron ore occur in the serpentine belt of the "Eastern Townships" of Quebec, which belt also includes the asbestos mines. The exploitation of these deposits is very recent, and the methods of working them are yet generally primitive. Only the richest ores have been extracted, but with the development of the industry, it may be surmised that mining and concentrating machinery will be brought into use, so as to allow of profitably working the poorer deposits which abound in the district. By referring to the table of analyses it will be seen that the product obtained is quite marketable, even with only the rough hand selection which it undergoes. The chromite finds a ready market in the United States and in Scotland.

Very little work has been done on the deposits of this township, although an opening has been made on Lot 9, Range VII. The serpentine belt in this region is rather considerable and may, perhaps, contain some deposits worth mining.

This mineral occurs in a vein of quartz about one foot wide, accompanied by its decomposition-product, tungstic acid. An analysis of the scheelite made in the laboratory of the Survey shows it to contain 79.9 per cent. of tungstic acid, or within 7 per cent. of the theoretical quantity. No attempt has yet been made to work the deposit.

This deposit consists of a vein of quartz about two feet wide, running with and enclosed by gneiss, with molybdenite distributed abundantly through the quartz in crystals, which are generally coated with molybdite, the yellow oxide of molybdenum.

This deposit occurs in a pyroxene rock in association with iron-pyrites and where weathered shows much molybdite.

MATERIALS USED IN THE PRODUCTION OF LIGHT AND HEAT.

In Nova Scotia there are several extensive areas of bituminous coal which have been mined for many years. In New Brunswick is a small productive area with thin seams, also bituminous. The above are all in rocks of Carboniferous age. In the Northwest Territories very large tracts of the prairie country are underlain by coal-beds, varying in quality from lignites in the east to bituminous coals in the west, as the foothills of the Rocky Mountains are approached.

In the mountain region itself is a coal-basin yielding anthracite and steam coal, at Banff and Canmore. Across the watershed in British Columbia is the Crow's Nest Pass field, now being opened up, and on Vancouver Island are important collieries that have been worked for many years. Besides these, this province has numerous occurrences of coal in the Tertiary rocks of the interior, most of these being lignites, but some becoming true bituminous coals. There are also many known occurrences of coal in Cretaceous rocks in other parts of British Columbia, not yet accessible economically. Anthracite, bituminous coal and lignite occur on the Queen Charlotte Islands, but are not at present ⚫ worked.

It will be noted that all the known coals and lignites from Manitoba westward are either Cretaceous or Tertiary in age, while no coals of a later period than the Carboniferous proper occur in the Maritime Provinces of the east. It is important also to note that both the Atlantic and Pacific coasts of Canada are well supplied with good coal.

Anthracite Coal.

Anthracite Mine, Anthracite, Alberta, N.W.T... Geological Survey. 9. Anthracite coal.

The Anthracite mine is situated in the Cascade coal-basin. The coal at this place, owing to great local alterations, has become an anthracite, although of Cretaceous age. The capacity of the colliery is about 150 tons a day.

A recent analysis by the Geological Survey shows it to have the following composition:

In character the Cretaceous and Tertiary coals of British Columbia range from anthracite to lignite, showing that the grade depends on their degree of metamorphism rather than on their geological age. Three principal coal-fields, all of Cretaceous age, may be mentioned, being those that are at present largely worked, as follows:

The Nanaimo field, from which the above specimens are derived, is situated in the south-eastern part of Vancouver Island. Its area has been estimated at about 200 square miles. Two seams, at least, of workable thickness are known, but the measures being much folded and cut up by faults, it is very difficult to correlate the beds in the various parts of the field.

The product of both this and of the Comox areas is largely exported to California and to some extent to various other Pacific ports, where it competes successfully with coals produced in the United States or brought from New South Wales, England, etc.

The New Vancouver Coal Mining and Land Co. was organized in 1862 and reorganized in 1889. The Southfield colliery is situated five miles from Nanaimo. The seam worked varies from six to twelve feet in thickness. The system of working is pillar and stall.

The No. 1 shaft is on a seam five to twelve feet in thickness. The workings of this colliery are under the waters of Nanaimo harbour and beneath the surface of Protection Island.
