Introductory The steady advance in the price of lead and zinc in the metal markets of the world during the past few years has resulted in an active search for new deposits of these metals, and to the re-examination of known properties that are now idle. There are a number of deposits of these metals in eastern Canada, the best known of which are the Tetreault mine at Notre Dame des Anges, Que.; the Reader mine on Calumet island, Que.; the Stirling property in Cape Breton, and the Federal mine in Gaspe district, Que. . The author has run concentration tests on the ores from the first three mentioned properties. The ores from Notre Dame des Anges and Calumet island presented problems in concentration which were not successfully solved until the past year. Although considerable experimental work has been done by the Ore Testing Laboratories on the ore from the Stirling mine we have not been successful in developing a satisfactory method of treatment. Character and Types of Ores Metallurgically the lead-zinc ores of eastern Canada may be classified into three distinct types as follows: First: - Ore in which the sulphide minerals are fairly coarsely crystalline and can be freed by crushing to 40 or 60 mesh. The zinc blend has a high iron content (not marmatite) and gives a dark brown colour on grinding. The ores of Notre Dame des Anges and Calumet island, Que., may be cited as examples.

During the last three years prospecting has been active in southeastern Manitoba and a number of interesting gold, nickel and copper deposits have been discovered within an area 90 miles north of the international boundary, and extending about 40 miles westerly from between mileage 60 and 110 on the Manitoba-Ontario boundary. As known at present, two-thirds of this area of 2,000 square miles is underlain by pre Cambrian granite and granite gneiss and is not likely to contain mineral deposits of economic importance. The remaining one-third is underlain by metamorphosed sediments and lavas (greenstones), penetrated by the granite and granite gneiss and, at various localities, cut by bosses, sills, or dykes of gabbro, diorite, granodiorite, and other types of intrusives. The nickel, copper, and gold mineralization accompanied or followed the intrusion of these different rock types. The gold deposits are limited in distribution, so far as known, to the northern part of this prospecting area and occur along Manigotagan and Wanipigow rivers. These deposits have recently been described in some detail, (3) and therefore only the copper and copper-nickel deposits of the southern part of this area, along Oiseau and Maskwa rivers, will be described in this paper.

Canada ranks second in the list of world consumers of natural gas. In 1923 our production was nearly fifteen million thousand cubic feet valued at $5,800,000. Our output, however, appears very small compared with that of the United States, which in 1923 totalled over one thousand and eight million cubic feet, valued at $240,000,000. Natural gas is found in commercial quantities in three? provinces in Canada. New Brunswick: Natural gas in New Brunswick has been utilized commercially only since 1912,although the investigation of oil and gas possibilities of the province commenced as early as 1859. The annual production is a little more than one-twentieth of the total Canadian production and remains fairly constant from year to year. Ontario: In Ontario the earliest gas wells were drilled in Essex and Welland counties between the years 1885 and 1890. On account of the small demand in Canada the cities of Detroit and Buffalo were supplied with large quantities of gas from these wells, but this export was curtailed in 1898 and finally ceased in 1900. The production of natural gas in Ontario, mainly from fields in Lambton, Kent, Essex, Norfolk, Haldimand and Welland counties, increased rapidly from 1900 until the peak was reached in 1917, when over nineteen million thousand cubic feet valued at $3,641,587 was consumed.

Situation: Creighton mine, situated about twelve miles west of Sudbury, Ont., on the Algoma Eastern railway, is owned and operated by the International Nickel Company, incorporated in the United States under the laws of New Jersey. The ore is smelted at Copper Cliff, near Sudbury, and the matte is refined at Port Colborne, Ont., on lake Erie. Geology: The ore occurs in what is known locally as 'the basin' near Sudbury (Figure 1) the central part of which is composed of the Animikie series of sediments, consisting of sandstones, slates, tuffs and conglomerates. The basin is about 16 miles wide and 36 miles long. The Animikie sediments are surrounded by a sill of norite - a gabbro rock in which the pyroxenes are orthorombic. On the outer contact of this norite the sulphide deposits occur and the Creighton deposit, similar to others, lies on the southern edge of this basin. There are two orebodies at the Creighton, the upper one called the footwall orebôdy, and the lower one the hanging-wall orebody. The hanging-wall of both of these bodies is norite, and the footwall of the upper one is granite. The two are separated by an intrusion of greenstone which forms the footwall of the lower body. The ? maximum length of the deposit is 1000 feet and the maximum width is approximately 300 feet. It narrows at the ends and is somewhat lenticular in shape. The dip is about 45 o to the west, and the strike is north and south. The orè is a mixture of three minerals - pyrrhotite, chalcopyrite and pentlandite. The pentlandite, which is distinguished by its cleavage from the other two, is apparent to the naked eye only in the lower orebody and is more finely disseminated in the upper one. The lower body contains a little higher percentage of nickel.

In the early explorations of the Northwest, the search for minerals played a not inconsiderable part. The first episode had its disillusioning sequel. Sir Martin Frobisher, in 1576, sailed up that bay in Baffin land now known as Frobisher bay, thinking that he had the coast of Asia on his right hand. He brought back from this expedition a piece of 'black earth' from Hall island, from which an alchemist by coaxing nature, or his own conscience, obtained gold. A second expedition of three ships was fitted out in 1577, and a third of fifteen ships in 1578. The ships were loaded with this 'black earth', which on subsequent investigation was found to be worthless, and interest in minerals for the time being ceased. In 1612 Hall and Baffin went in search of a gold mine near the Arctic circle on the west coast of Greenland, reported to be worked by the Danes. They found old workings, but no ore. To come nearer the Hudson Bay area, it is noteworthy that the charter granted by Charles II to the Hudson Bay Company in 1670, as a result of the explorations of Radisson and Groseillers, was given "-in consideration for their having at their own cost and charges undertaken an expedition to Hudson bay in the northeast parts of America, for the discovery of a new passage to the South sea, and for the finding of some trade for furs, minerals and other considerable commodities, and of their already having made by their undertakings such discoveries as did encourage them to proceed farther in pursuance of the said design, by means whereof there might probably arise great advantage to the King and his Kingdom - ".

"It is a truism that the metals, and particularly the precious metals tend to monopolize the attention of those interested £n the mineral industry. This is a tendency to be mildly, but actively and continuously combatted if we are to have a well-rounded mineral development." There are in the province of Ontario a number of industries centred about the non-metallic minerals. Too little is heard of the part these play in our industrial life. It is with the intention of showing what the gypsum industry is doing in Ontario that this paper is written. The writer lays no claim to any originality in the discussion and merely offers some material in an endeavour to assist in bringing about that 'well-rounded mineral development' sought for Ontario. M. Y. Williams in his "The Silurian Geology and Faunas of Ontario Peninsula and Manitoulin and Adjacent Islands"1 in discussing the industries dependent on the Silurian rocks of south-western Ontario points out that "the splendidly ordered gypsum mine at Caledonia, formerly owned by the Alabastine Company of Paris, and now owned by the Ontario Gypsum Company, is a revelation to the average man, who disconnects mining entirely with this part of Ontario". This region is better known as one of the richest and most thickly settled agricultural areas in Canada.

British Columbia, unlike the Prairie Provinces, cannot lay claim to vast prairies. She can, however, claim many valleys, uplands and plateaus that are capable of marked agricultural development. It has been said that British Columbia is not an agricultural province. This may or may not be true, but at the present time agricultural production in this province stands second only to that of forestry. The industry has advanced from a total production of 8 millions in 1908 to a total production of 60 millions in 1924, a total increase of approximately 650 per cent in 16 years. In the last 10 years production has increased from 30 millions to 60 millions. No other industry can point to such a rapid development. In 1908 British Columbia imported 12 million dollars worth of foods compared to the 8 millions which were produced at home. In 1924 she imported 20 million dollars worth of foods compared to the 60 millions worth produced at home. In addition we exported foods to the value of approximately 10 million dollars. British Columbia is therefore self-sufficing in-so-far as values ar.e concerned except for approximately 10 millions of dollars. It is not to be expected that this province will ever grow all the coarse grains that she may require: these, along with certain meats, will always be a heavy item in the imports. We are concerned at the present time more with the value of the products than with the quantities produced: in other words, with quantities only in-so-far as ? quantities improve value.

Introduction An investigation of the bituminous sands of Alberta was begun by the Mines Branch, Department of Mines, in 1913. This investigation was interrupted during the period 1916-19, but was resumed in 1920. Work completed in October 1924 has included detailed topographical surveys of extensive areas, examination and sampling of principal outcrops, the mining of trial shipments, laying of demonstration pavements, and a study of methods adapted to the recovery of hydrocarbons from the crude bituminous sand. Bituminous sand consists, for the most part, of clear quartz grains, cemented together by petroleum residuum or bitumen. In form the quartz grains are most irregular, varying from sharply angular to smooth, waterworn shapes. The bitumen has a specific gravity of 1.018 and has a penetration of 9.00 mm. (77° F. 100 grams 1 sec.). The percentage of bitumen associated with the sand varies from 5 to 25 per cent. A large tonnage is available in which the percentage of bitqmen is 15 per cent or over. Production Up to the present time, production has been restricted to requirements for experimental .and demonstration work. The total quantity shipped for such purposes has not exceeded 750 tons.

Water, water everywhere, but not a drop (fit) to drink! Trite, but how often only too true? What is there met with in mining which, under various circumstances, may be said to be the most sought-for and highly-prized and also the most objectionable and most feared? Water! What visions that combination of five letters brings to all thoughtful minds? Up to near the end of the eighteenth century water was thought lo be an element but was then discovered to be the result of the combustion of two volumes of hydrogen with one volume of oxygen, and water so produced is chemically pure. Pure water is a clear and colourless liquid when seen under ordinary conditions, but appears bluish when seen through a long tube, and this same bluish tint may be observed in many lakes, especially those of glacial origin. A story often told describes a prospector in the desert who, failing to find water to replenish his canteen, suffers torture and death under fearful circumstances. Then again we may recall the flooding of mines, where water poured in so quickly that there was no opportunity of saving the unfortunate workmen. Instances might be multiplied without number showing that either the lack or excess of this essential fluid has taken heavy toll of human life. In all branches of mining and associated industries water must be dealt with to a larger extent, from an economic point of view, than any other substance, and very often the purity of the water is a matter of considerable importance.

Within the Dominion of Canada occurrences of petro-liferous shales have been known for many years. Nevertheless, with the exception of a comparatively brief period, Canada has had to depend largely on foreign sources for its supplies of crude petroleum and petroleum products. Attempts were made to retort local shales in 1859, near Collingwood, Ontario, and again in 1862, near Baltimore, New Brunswick. In each instance these attempts were abandoned owing to the rapidly increasing production of well petroleum from the newly discovered pools of western Ontario and Pennsylvania. Now, after a lapse of nearly sixty years, attention is again directed to the commercial value of Canadian shales as a possible source of crude petroleum. Province of Nova Scotia: The principal deposits of oil-shales occur in Pictou and Antigonish counties and have been known for more than 60 years. During the three years following its discovery, several thousand tons of a particularly rich sub-variety, known as stellarite (stellar coal or oil coal) was mined near Stellarton in Pictou county. It is stated that stellarite yielded upwards of 10,000 cubic feet of 36 candle gas, and that selected samples gave a yield equivalent to 170 Imperial gallons (204 U.S. gallons) of crude petroleum per ton. The average petroleum content of a cargo shipped to Boston was 48 Imperial gallons (57.6 U. S. gallons) and the associated shale or 'bat', gave a yield of 39 Imperial gallons (46.8 U.S. gallons). Part of the above output was shipped to retorting works in Boston and in Portland, and part was mixed with bituminous coals for the enrichment of illuminating gas. Following the discovery of well petroleum in Ontario and in the United States, the mining of stellarite ceased.

Modem civilization is indebted to that most ancient of the skilled crafts - the art of stone working, as the one consistent means whereby the dim un-recorded past has conveyed to our modem schools of science volumns of facts, written in characters of imperishable stone. Although left, centuries ago, to ruin and decay, architectural examples of the ancient building crafts still remain to the glory of the old master-builders, whose accomplishments in that remote age continue to influence and inspire their modem successors. Present-day architects and builders will leave to posterity just as faithful a record of our modes of living and of the methods now adopted for protection, as if it had been made by written word; and our craftsmen have profited greatly, in meeting modem requirements, by taking advantage of the indurance and utility of stone. Stone in all ages and stages of the world's civilization and development has been the material chosen by the masterbuilder, the one material possessing qualities that render it most desirable in affecting the artistic ideals of each period. It perfects the science of architecture through its durability and thus renders possible the study of man's workmanship in stone throughout periods of civilization of which we have no specific written account. Other materials have been used for the construction of man's habitations, but none have withstood the test of time, nor have established the credit of designer and builder so well as stone. _All other materials fall into ruin and decay, leaving neither mark nor monument for the enlightenment of mankind.

This short article is quite different to the general run of papers that are presented to the Institute, but no apology is offered because I consider that first-aid and mine-rescue work are of equal importance to many other subjects that are dealt with in our Transactions. Members of the Institute should be as much interested in the safety of persons engaged in the mining industry as they are in the practical methods of modern mining. We must not only do our best to conserve life and property by adopting every known device to that end, but we must also prepare ourselves so that we may take prompt and effective action when life is in danger, or when property is subject to loss. The need for such preparation in Alberta is perhaps greater than in most places where mining is carried on, and we must spare no effort to assemble at every mine men who are well trained in first-aid and mine-rescue work. The large area over which the mines are distributed renders central training stations out of the question, hence the need for local rescue-teams. Hospitals with skilled staffs, close enough to the mines to be convenient, also seem to be out of the question; therefore the greater need of a high standard of first-aid training for the people in our mining camps. The Government mine-rescue cars are supplied with the equipment necessary for training persons in this essential work and also for dealing with disasters should they occur. The question then arises: are there a sufficient number of men who are trained ? If so we can rest assured that what is possible to be done will be done. But if a sufficient number of trained men are not available much loss of life and damage to property is likely to result.

Gold-bearing quartz veins and replacement chalcopyrite deposits are the two important types of metallic mineral deposits of the east central Manitoba mining district. The gold-bearing veins occur along Manigotagan valley, northwest for 25 miles from Beresford lake, and the copper deposits along Oiseau valley, between Oiseau lake and the east end of Lac du Bonnet. Lithium-bearing minerals of possible commercial value have recently been discovered in pegmatite along Winnipeg river about 10 miles east of Point du Bois. There are also prospect pits with showings of galena, sphalerite, cobaltite, pentlandite, nickeliferous pyrrhotite, arsenopyrite, pyrite, molybdenite, cassiterite, and other minerals, but the various occurrences of these minerals, as exposed, are small. The bedrock and mineral deposits of this mining district are Precambrian and resemble in many respects the formations and mip.eral occurrences of western and northern Ontario. Although prospectors visited eastern Manitoba at intervals during the last fifty years, effective prospecting did not begin until 1913 or 1914, and not until 1923 were skilfully directed, systematic explorations undertaken. It is true, that between 1913 and 1923 considerable sums were expended in a number of attempts at mining and milling the gold-quartz ore, but these enterprises failed partly through poor management or attempts to develop veins that were too small or too low-grade to be worked at a profit under the existing conditions of transportation and power supply.

The prosperity of any nation depends, to a large extent, on its natural resources such as oil, coal, 'metal, timber, waterpower, and fertile soil. Each one of these resources forms the basis of a huge industry. The mining and smelting industry ranks among the first since it paves the way for a number of other industries. The mines and smelters provide a market for electric power, coal, timber, and agricultural products: other industries in turn provide a market for metals and non-metals. The real pioneering, however, is done by the prospector who goes into the wilderness to search for the ores from which the metals are to be extracted for the use of men. Prospecting is an interesting and fascinating occupation. There are many difficulties and hardships in the way but the lure of gold and the vision of finding an outcrop that may develop into a large bank account, within a reasonably short time, will urge the prospector forward. Thus, on the outskirts of this northern hemisphere hundreds of prospectors are searching and toiling and of whom nothing is known or heard until they reach civilization and announce a new discovery. Then a mad rush takes place and everybody who can afford to go will take a gamblers chance and plant stakes in the neighbourhood of the new discovery, or wherever an outcrop of mineralized rock can be found, with the hope of winning a fortune.

A casual reading of the geological literature extant to-day would give one the impression that carbon is an element which by some chance or another always existed at or near the surface of the earth, and was never of a magmatic origin. The carbonaceous matter in shales is said to be of vegetal derivation; petroleum is stated to have been derived from vegetable matter or from marine animal bodies; if carbon or bituminous matter is found in igneous rocks or associated with metallic ores, the statement is made that deeply buried carbonaceous sedimentaries were undoubtedly the source from which such carbon or bituminous matter was derived. This, I do not consider a reasonable or common sense view of the matter. Carbon is one of the elements of which the earth is composed. In the table giving the periodicity of the elements it comes sixth in the order of increasing atomic weights. It is an element formed like all the rest were formed, and must be as common to the interior of the earth as the rest of the eighty-odd elements so far discovered. The spectroscopic analysis of light from the sun, and the stars, shows the presence of carbon in the sun and in the colder stars. Thus with carbon, an element, found throughout the universe as well as on the earth, it is entirely reasonable to consider it as present in the interior of the earth with the other elements. Such being the case, the magmatic origin for the various forms of carbon in rocks and ores is a rational and logical conclusion. If but a small fraction of thought and effort was made along these lines, which is made in fostering the idea of the organic origin of the carbon found in the earth's crust, untold advances in this phase of geological science would result.

It was to be expected that the convening of the first Empire Mining Congress in June, 1924 in the city of London would turn men's thoughts very definitely to the question of exploring the mineral resources within the British Empire, the examining of her strength and her weakness in mineral material, and the consideration of steps that might advisedly be taken to strengthen her trade in minerals. That expectation was in part realized, though in the British way of presenting the case, and permitting the inferences to be drawn by implication. The opening address by the President of the Congress, to whom the Empire meant so much, gave a résumé of the contributions to the mining industry which were being made by the constituent parts of the Empire. The papers from the Institutes in Australasia, South Africa and Canada provided the details of resources and practice: while the individual contributions to the proceedings dealt with those phases of the mineral industry which are fundamental to the economic strength of British people, or to the health and well-being of the workers. While the subject matter thus presented was British mineral resources, and while the first consideration was the co-ordination and co-operation of British enterprise throughout the world, there emerged very clearly the wider viewpoint that the discussions had to do with a world industry, and with the contributions that that industry was making, and could further make, to the advancement of civilization irrespective of national boundaries, the world over. The invitations to representatives of the mining industry from the United States to participate in the Congress, and the warmth of approval which that participation evoked, were indications that such a congress cannot to-day be merely national in scope, and that trade in minerals, as in other natural resources, cannot be confined within national boundaries, but will seek its channels, unless artificial obstructions are too great, where the natural channels already exist.

Stone that may be applied to purposes of construction is available in nearly all the inhabited parts of Canada, the most important exception being the prairie region, but, even here, the deficiency is overcome in many parts by a wealth of glacial field-stones. In many parts of the country, also, the accessible stone is of a quality so poor that brick is more generally used. There is a great difference, however, between stone that 'may be used' and stone suitable for buildings of a monumental type or even for 'trimmings' on the better class of dwelling in the cities and towns. It is in the latter sense that the expression 'building stone' is commonly used. Thus restricted the term includes varieties of sandstone, limestone, and granite, using the latter word in the custom of the quarryman, not only for the true granite of the geologist but for many other igneous rocks as well. Building stone of high quality grades imperceptibly into stone suitable for monuments, particularly in the case of the granites. The present review will deal with building and monumental stone in this restricted sense and will omit marble, although that material has been used to some extent for building. For instance, the Great West block in Winnipeg is built of marble from British Columbia.

In this paper is presented a review of the changes that have taken place in certain Canadian non-metallic mineral industries since 1909. The fifteen-year period 1909 to 1923, inclusive, has been selected for two reasons. In the first place, statistical treatment of the subject under review has been nearly uniform throughout the period. In the second place, this decade and a half is itself further subdivisible into three well marked quinquennial periods, the middle one covering the period of the great war when industrial conditions were greatly disturbed. It then becomes possible to institute certain comparisons between equal periods before and after the war disturbances. The items selected for inclusion in this review are certain of the more important members of that class of minerals usually grouped together under the heading of non-metallics. They are all minerals of which Canada is known to possess important resources, and which are indispensable to many of our greatest manufacturing industries.

At the Annual General Meeting of the Institute in 1924. I endeavoured to present the position held by the mineral industries in the commercial life of this country. The facts and figures were presented at that time in a detached way. Since then, however, I have made some attempt to analyze them in order to determine the causes for that position and to draw some conclusions as to the future of the mining industry. As everyone knows, our trade figures are very often used in political discussion, especially in discussion of tariff policy. It would be entirely out of order for me to say anything touching the tariff issue and I want to have it clearly understood that, in my opinion, the material I am about to present contains not a single statement or conclusion which anyone would be warranted in using as an argument for either a lower or a higher tariff or for tariff changes of any kind. As a starting point, let me re-state, very sketchily, Canada's general situation in external trade. In the last calendar year, 1924, we sold Canadian merchandise of all kinds to other countries to the value of $1,045,000,000 in round figures. Our purchases abroad reached about $893,000,000. Thus our sales exceeded our purchases by roughly $152,000,000. In other words, we had what is known as a 'favourable balance of trade' - one of the biggest favourable balances we have ever had in our history. The proceeds of our sales of Canadian products enabled us to meet the bills for all our purchases of foreign commodities and, in addition, placed a large surplus to our credit with which to offset our interest charges and other obligations abroad.

In his report on the Coal Resources of Southern Vancouver Island, Mr. J. D. MacKenzie stated that: "For various reasons it has been imagined that the coal deposits of Vancouver Island are extremely large and readily available." "Unfortunately," he added, "neither of these assumptions is correct." The chief disability under which the Island mines now labor does not concern the extent of the deposits. There is ample coal for the present demand. It does, however, concern the availability of the coal. If it were readily available the fuel-oil competition would not be serious and there would be no competition with Alberta, American, Welsh, or Australian coal along the Pacific Coast, for Vancouver Island coal could be produced at a price that would cut out all competition. The outstanding operating difficulty common to all Island mines is the extreme irregularity of the coal seams. To most people a coal seam is synonymous with uniformity, and in most coal seams a condition found at one point will be repeated at other points in the same seam throughout the basin. The accompanying drawings show how very far this is from being true in the Cassidy mine, which, in many respects, is typical of Vancouver Island mines. Figure I is a plan covering about 160 acres of the Douglas seam, the only workable seam in this part of the district. The area shown represents what has been the best producing part of the mine and indicates the very large percentage of the seam where the coal is either entirely lacking or so small in amount that it cannot be profitably recovered.
