discovered. It is owned by the contributor. The ore sometimes occurs in large octahedral crystals nearly six inches in diameter.-Laurentian. 18. Bristol, Q., lot 22, range 2......Geological Survey, and J. Bell, Arnprior. a. Specimen of magnetic iron ore. This ore occurs in a series of beds which are interstratified with reddish hornblendic gneiss and glistening micaceous and hornblendic schists of Laurentian age. The thickness of what appears to be the uppermost and most important bed has not been ascertained; but the lowest one exposed is about nine or ten feet thick. The property is owned by Messrs. Taylor & Burns, of Pittsburg, and openings were first made during the winter of 1873-74. Several thousand tons of ore have been raised but not shipped. The following is an analysis from the Report of the Geological Survey for 1873-74, page 208: The ore though generally known as magnetite contains a considerable proportion of hematite. Pyrites is also present in larger quantity than desirable.-Laurentian. 19. Hull, Q., lot 11, range 7.. .A. H. Baldwin, Ottawa, a. Specimen of magnetic iron ore. b. Photograph of blast furnace and charcoal kilns. The "Hull Mines "are situated on lot eleven in the seventh range, and lots twelve and thirteen in the sixth range of Hull, about six miles from Ottawa. They include the Forsyth and Baldwin mines, which are about half a mile apart, though probably on the same bed. The ore occurs in crystalline limestone, and has a thickness in some places of over sixty feet. It was first mined in 1854 by Messrs. Forsyth & Company, of Pittsburg, and more recently by A. H. Baldwin, of Ottawa, about 30,000 tons having been taken from the Forsyth and 4,000 from the Baldwin mine. No mining has been carried on since 1873, in which year about 15,000 tons of ore were shipped to the United States. The blast furnace is situated near the Gatineau River, about three miles from the Forsyth mine. It has not been in blast since 1868, and was several years ago much injured by fire. Some of the ore contains an admixture of hematite, and is known as "red ore," while that which is essentially magnetite is known as "black ore." The following analyses of these two varieties are by Dr. T. Sterry Hunt : The ore frequently contains scales of graphite. In the blast furnace it yields from 60 to 62 per cent. of iron.-Laurentian. 20. Grandison, Q............ a. Specimen of magnetic iron ore. 21. North Mountain, King's County, N.S.. Geological Survey. ..David Chipman, Berwick, a. Specimen of magnetic iron ore. In the great ridge of Triassic trap which borders the south-eastern side of the Bay of Fundy thin veins of magnetite are occasionally found. A few attempts have been made to work them, but they can scarcely be regarded as of economic importance. The ore is often beautifully crystallized in dodecahedra, or in combinations of the octahedron and dodecahedron.-Triassic. Many of the rocks in the great Laurentian series, which is extensively developed to the north of the gulf of St. Lawrence, contain small disseminated grains and crystals of magnetite and ilmenite, which, on the disintegration of the rocks, are gathered together by natural processes of concentration, and form important deposits of "iron sand," stretching in some cases along the coast for many miles. Some of them are of recent origin, but others belong to the post-pliocene age, and are found as high as one hundred, and even two hundred, feet above the tide-level of to-day. With the ores of iron there are variable proportions of siliceous sand, and small quantities of garnet, so that artificial concentration is necessary to fit the material for metallurgical treatment. In practice this is effected by shaking-tables, but in a very incomplete manner. Dr. Hunt found the Moisie sand, before washing, to contain 46.3 per cent of magnetic grains, and after washing only 52.00 per cent. The washed sand contained 55.23 per cent. of iron, 16.00 of titanic acid, .07 of sulphur, .007 of phosphorus, and 5.92 of insoluble matter. (Report of the Geol. Survey of Canada, 1866-69, p. 267). The only locality at which the sands have been extensively worked is at Moisie (or Moisic), near the mouth of the Moisie River, and about 330 miles below Quebec. Here several bloomary furnaces were built by Mr. W. M. Molson, of Montreal, in 1867, and since then a considerable quantity of excellent iron has been made, and in part shipped to England and the United States. At present the Moisic Iron Company is in insolvency, and the works closed. The property comprises, 3,300 acres of land, eight bloomary furnaces, capable of producing thirty tons of blooms a week, a reverberatory furnace in which to re-heat the blooms for a second hammering, a tilt hammer, set of rolls for making bar iron, forty miners' cottages, hotel, &c. Belonging to the same estate there is also a valuable rolling mill and nail factory in Montreal. While the works were in operation about one hundred hands were employed at Moisie. HEMATITE, (including crystalline and earthy varieties.) 1. Silver Lake Mining Location, Thunder Bay, Lake Į Superior..... Geological Survey. a. About 150 lbs. of broken ore from beds of fine-grained compact hematite opened on the western part of the location. b. About 150 lbs. of broken ore from the lowermost of the beds of botryoidal hematite or "kidney ore," opened about a quarter of a mile east of the above. c. Piece of ore weighing about 100 lbs., similar to the last, but taken from a higher bed in the same part of the location. The above location is situated five and a half miles N. E. of the head of Thunder Bay. The ore occurs in a group of beds, not less than forty or fifty feet in thickness, associated with compact sandstone, and ferruginous limestone suitable for a flux, near the base of the Nipigon series. Most of the beds consist of very pure hematite, containing, on an average, 68 to 69 per cent. of iron, according to the analyses of Prof. H. Alleyne Nicholson, of Newcastle, and Dr. Ellis, of Toronto. The outcrop of the ore beds has an elevation of 470 feet above Lake Superior, and is very favourably situated for mining and for smelting with charcoal.-Nipigon Series. 2. Mining lots 67 B and 68 B, Loon Lake, near Thunder Bay, Lake Superior........ a. Small specimen of hematite from a bed. T. D. Ledyard, Toronto. The deposit from which this specimen is taken is said to be of considerable extent, and to run north-westward from Loon Lake, which is situated about five miles north of the head of Thunder Bay.-Huronian. 3. The Dickson Location, Desert Lake, near Bruce Mines.... a. Three specimens of hematite, weighing about 150 lbs. Geological Survey. This location comprises Blocks A 1 and A 2, situated on the north side of Desert Lake, and about five miles from Portlock Harbor on Lake Huron. The vein, of solid ore like the specimens, 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 for nearly a mile on the location, and in one place shows to great advantage for mining, at an elevation of 200 feet over Desert Lake, which connects by a navigable river (The Thessalon) with Lake Huron. Dr. Ellis of Toronto finds the ore to contain 56 per cent. of iron and no appreciable quantity of sulphur or phosphorus. E. B. Borron, M.P., Hamilton, Ont., is agent for the property.Huronian. 4. Location Y VIII., Desert Lake, near Bruce) Mines...... a. Specimen of hematite, weighing 155 lbs. James Stobie, Bruce Mines. This location adjoins the Dickson, and the vein is a westward continuation of the one on the latter. At the part from which the specimen is taken it is said to be nine or ten feet thick. It cuts similar quartzite and underlies to the northward at an angle of 10 from the perpendicular. The surrounding country is well wooded.-Huronian. NOTE. Besides the above localities for hematite in the Lakes Superior and Huron region, the following are worth mentioning, the quantity in each case apparently indicating an economic value: East side of Lake Nipigon near the mouths of Oniminisagi or Red Paint River, and of the Sturgeon River, slaty hematite ores. (A specimen from the latter place was found to contain 36.06 per cent. of iron, and to be of such a nature as to render it easy of reduction); hills east of Lake Nonwatanose, Black Sturgeon River (a red earthy hematite); west point of the largest of the Slate Islands, (impure slaty ore); near Wallace mine Lake Huron (in combination with magnetite); about 10 miles up the east branch of the Montreal River, Ottawa valley (veins of specular iron in quartzite); foot of Big Rapids, below the Long Portage, south branch of Moose River (a large deposit of siliceous carbonate of iron passing into hematite). 5. Madoc, O., east half of lot 12, range 5.... a. Specimen of red hematite. T. C. Wallbridge, Belleville. b. Specimen of pig iron smelted in the blast furnace at Three Rivers. From a deposit locally called Wallbridge's Hematite Mine; but concerning the extent of which little is known. The ore is a finely granular hematite, of a steel-grey colour on fresh fracture, but weathering red. About eight tons were extracted, and sent to the furnace at Three Rivers as a sample lot for smelting. The iron produced was found to be of superior quality.-Laurentian. 6. Dalhousie, O., east half of lot 1, range 4............ Alexander Cowan, Brockville. a. Specimen of red hematite. b. Plan of mine by Mr. Gerald C. Brown. The mine is about twelve miles from the town of Perth, and is commonly known as the Dalhousie or Cowan Mine. It has been worked for several years by Alexander Cowan, Esq., of Brockville, under the management of Mr. Gerald C. Brown, and was at one time leased to and worked by Messrs. Spearman & Hanna of Cleve land, Ohio. The ore is a beautiful red hematite, and occurs in a tremolitic dolomite. The bed averages seven feet in thickness, striking N. 60° E. (mag.) and dipping to the south-east at an angle of 60°. When the mine was opened up in 1866 there appeared to be two beds cropping out in places at the surface, with four or five feet of dolomite between them. The uppermost and smaller of these was found to run out at a few feet in depth, and to extend but a short distance in the direction of the strike. The larger deposit was in places as much as nine feet thick at the surface, and at a depth of eighty feet had an average thickness of four or five feet. From 3,000 to 4,000 tons of ore were for several years annually raised and shipped to Cleveland, the cost of carriage, as a rule, not exceeding $4.60 per ton. Owing, it is said, to the dullness of the market, no mining has been carried on since 1873. The ore is very free from deleterious constituents, and contains an average of over 60 per cent. of iron. The geological position of this deposit appears to be above that of the magnetites of Ontario.-Laurentian. 7. McNab, O., lot 6, concession C & D. a. Specimen of red hematite. Geological Survey. This deposit occurs near the Fall of the Dochart, and about a mile from the shore of the Lac des Chats. The thickness at the surface was about thirty feet, It is possible but at a depth of eighty feet, the ore is said to have thinned out. however, that if further mining operations were carried on, the bed on some portions of its course would be found to extend to greater depths. The ore is of excellent quality as will be seen from the following analysis: The ore of the Haycock location occurs in highly feldspathic gneisses belonging to the Laurentian system, and forms a series of parallel beds striking north-east and south-west and dipping to the north-west at an angle of about 50°. The beds range from a few inches up to several feet in thickness at the surface, and one of them, which was less than two feet at the surface, at a depth of fourteen feet is said to have widened to over twelve feet. The ore is essentially a hematite, but contains a small proportion of magnetic oxide, some specimens being readily attracted by the magnet. It is very free from impurities, and contains on an average about sixty-four per cent. of iron. The following complete analyses are |
