Even today there is some dispute as to who really discovered asbestos in this area. It is, however, known that among the first to exploit it commercially were the King Brothers from Quebec City. These men were not miners and came across their asbestos deposits only by accident--what they were really after was timberland. They did, however, recognize the commercial value of asbestos and in 1878 opened the King Mine in Thetford Mines. It is here that the history of the Asbestos Corporation Limited really starts. The mine was operated under their name until 1909 when the Amalgamated Asbestos Corporation was formed, which, along with KMX 00456 8 1 the King Mine, acquired the Beaver, the British Canadian and the Fraser Mines. It is an indication of the amount of asbestos in the area that today the present company is still extracting ore from all but the Fraser Mine. In 1912 the Amalgamated became the Asbestos Corporation of Canada Limited and it, in turn, became the Asbestos Corporation Limited in 1925. At the same time the present company also took over 7 other companies which were the results of earlier mergers themselves. Today the Company operates three open pits and one underground mine. The open pits are the Beaver, the British Canadian and the Normandie. The King Mine was originally an open pit but as it became bigger and deeper the cost of extracting the ore became excessive and a cheaper system of underground mining was necessary. Since late 1958, the ore from both King and Beaver mines has been milled at the newly expanded and modernized 5,000 ton-a-day Beaver Mill and the whole plant is now called the King-Beaver Mine. The British Canadian Mine located at Black Lake, P.Q., and the Normandie Mine, about 3 miles to the west, each have mills of 5,000 ton-a-day capacity. Along with these operating mines the Company owns mining rights to over 30,000 acres of land in five townships around Thetford containing millions of tons of proven ore reserves. Asbestos Corporation Limited is incorporated under the Dominion Companies Act and has an authorized issue of 3,600,000 shares of no par value common stock of which 1,800,000 shares are outstanding. The shares are quoted on the Montreal Stock Exchange and the Com pany has no long term debt. 93.5% of the Company's shareholders are residents of Canada. KMX 00457 9 KMX 00458 The name "asbestos" is applied to several classes of fibrous minerals, by far the most important of which is Chrysotile, the fine, white, silky fibre produced from our mines. Ninety percent of the world's asbestos used in industry is of the chrysotile variety which is the type produced in Canada. Chrysotile asbestos normally occurs in serpentine rock and is usually seen in the form of irregular veins in the rock, varying from microscopic thickness up to as much as 2 or 3 inches. The fibre runs across the vein at right angles to it from wall to wall and generally, therefore, the length of the fibre is governed by the width of the vein. The longer the fibre, the greater its value. The comparatively low yield of asbestos, which in Canada averages less than 5% of the rock mined, means that enormous tonnages of ore must be treated in large plants with a great deal of equipment before a reasonable output of finished fibre can be attained. The capital investment in the average asbestos mine is consequently 00460 KMX 00461 considerably higher than in other mining operations with a compar able sales volume. Asbestos mining is ordinarily a quarrying operation and this method pertains at all three of our mines, the King-Beaver, the British Canadian and Normandie. In addition, part of the ore for the King-Beaver Mill comes from the old King Mine underground workings. Regardless of the method of extraction, the treatment of the ore is basically the same and on the two previous pages there will be found a simplified flow sheet showing a typical asbestos milling operation. The first step in the operation shown on the previous page is the min ing or quarrying of the asbestos-bearing rock. After drilling, blasting and sorting, the ore is transported to the primary crushing plant where it is reduced in size, usually by a jaw crusher; a further reduc tion in size occurs at the secondary crusher which is generally of the gyrating type. Asbestos-bearing rock, as it comes from the mine, is normally wet and before any separation of the asbestos from the mother rock can take place the material must be thoroughly dried. Vertical tower dryers are used for fine ore and horizontal dryers for the coarser material. The dried ore is then drawn off and stored in a dry ore storage bin. Ore from the storage bin is brought to the mill as required where some of the free fibre is extracted and the remaining material passed over vibrating screens to separate the finer material. The ore is then given another crushing to free the asbestos fibre from the rock. The resultant mixture of rock fragments and asbestos fibre is then passed over an inclined shaking screen. The smaller particles of rock and the shorter asbestos fibres pass through the screen openings and KMX 00462 14 KMX 00463 are carried away for further treatment. The coarser rock fragments and the longer asbestos fibre remain on the screen and the shaking action of the screen brings the fibre to the surface. As the free asbestos fibre nears the end of the shaking screen, it is lifted off by air suction and aspirated through large air ducts to collectors. The material remaining on the screen, which consists mainly of unfreed asbestos in rock fragments, is carried off for further processing in fiberizers which release the rest of the fibre. The asbestos fibres are then cleaned and separated into standard commercial grades and bagged in 100-pound jute or paper bags for shipment. Driller at work in opan pit. MM Canadian Chrysotile Asbestos The following list of standard asbestos grades was set up by the Committee on Uniform Classification and Grading of Asbestos Mines Products. This committee was formed in 1931 at the instigation of the Minister of Mines of the Province of Quebec. The list of grades has been revised by such committee from time to time. The latest revision was made in July, 1959. Asbestos mines products are divided into two classes: "Crude Asbestos" and "Milled Asbestos" respectively defined as follows: "Crude Asbestos" consists of the hand selected cross vein material essentially in its native or unfiberized form. "Milled Asbestos" consists of all grades produced by mechanical treatment of asbestos ore. The "Crude Asbestos" and the "Milled Asbestos" are subdivided into groups designated and defined here below: Classification of the "Milled Asbestos" grades, in groups Nos. 3 to 7 inclusive, unless otherwise specified, is based on the Quebec Standard Testing Machine, a description of which and its operation is given on page 19. "SHIPPING TEST"--The shipping test is the average for each carload or smaller shipment, of tests of representative samples. "GUARANTEED MINIMUM SHIPPING TEST"--The guaranteed minimum shipping test is that below which the actual shipping test shall not fall.

EQUIPMENT (1) The Quebec Standard Asbestos Testing Machine, Model No. 2. Note: The machine shall be constructed and operated according to the specification issued by the National Research Council of Canada and described on page 19. (2) A 16 oz. scoop scale with graduations of 0.2 oz. and a sensitivity of 0.1 oz. (3) A smooth-surfaced mixing table. KMX 00465 PROCEDURE The sample to be tested shall be placed on the table and conditioned to normal room temperature and humidity. Examine the sample by passing through the hands to ensure that clots or lumps are broken up. The moisture content of the sample should not exceed 3% (significant variations, not normally encountered except when moisture content exceeds 3%). Erratic results can be expected beyond 3%. Mix thoroughly, then weigh accurately into the scoop of the scale, a 16 oz. 0.1 oz. representative portion. Place the sample in Box No. 1 of the testing machine, by letting it fall loosely from the scoop. The scoop shall be held from 6 to 10 inches above the screen cloth. Take care that when the cover of the testing machine is closed, the fibre shall not be compressed. When setting the boxes on the machine, be sure that they are lined up true to the platform and that the ends of the boxes always face the same way each time they are used. Start the machine and allow it to run until it automatically stops. Then, remove each tray and dump the fibre resting on each tray onto the mixing table, in individual piles, picking up and adding the loose fibre adhering to the cloth. Weigh separately the fibre recovered from each tray; the weights in ounces of the fibre shall be recorded as the Quebec Standard Test of the fibre sample. REPORT To the nearest 0.1 oz. the fibre retained in each box. An example of test results on a long (Group 3) fibre and short (Group 7) fibre would be: Box 1 W Box 2 4 mesh Box 3 10 mesh Box 4 Pan Long fibre Short fibre 3.2 9.4 2.8 0.6 16.0 oz. 0 0 6.2 9.8 16.0 oz. and its operation The Quebec Standard Asbestos Testing Machine Model No. 2 (see illustration) consists of a nest of 4 boxes, measuring 24%" x 14%", resting on a table which is driven by an eccentric with 25/32" throw and travel. The boxes, which are superimposed one above the other, are numbered from the top down--1, 2, 3 and 4. The bottoms of boxes Nos. 1, 2 and 3 are made of brass screen of the following specifications: Box No. Scroon opening Diameter of Wire 1 0.500" 2 0.1 S7" 0.105" 0.063" ( 4 mech) 3 0.053" 0.047" (10 mesh) 4--Receptacle for Hie fines which fall through the other three boxes. To make a test, 16 oz. of asbestos is placed on the uppermost tray (No. 1), which is then covered and tightly clamped. The machine is started and by means of an automatic device is kept going until exactly 600 revolutions have been made. (The speed of rotation is 328 r.p.m.) At the end of this time the asbestos which remains on each tray (box) is weighed. This gives the grade of asbestos fibre; the longest fibre naturally stays on the screen with the largest opening, whereas shorter fibre, according to its length, remains on screen (or tray) 2 or 3, or drops into the pan (lowest tray). The more fibre retained on the first screen, and the less fibre falling into the pan, the higher the grade and therefore the greater its value. If, for instance, a customer buys 3R fibre of the specification 4-7-4-1, it means that in a sample of 16 oz., representing the average of the lot shipped, 4 oz. will remain on the top screen, 7 on the second and 4 on the third, while 1 oz. will go through all the screens into the pan. It is evident that the figures of the test represent the proportion in ounces of the different lengths of fibre in a pound of asbestos.

Testing the surface area of a grade, \ \ lb r i 1 i I J' li I 4 .r 20 To-day's exacting requirements for asbestos fibre demand high standards of quality and uniformity and with this in view, we established, some time ago, a Quality Control Department whose main function is to ensure that all shipments of fibre from our mines measure up to the closely stipulated specifications for each grade. Each mill has its own Quality Control testing laboratory which constantly checks production circuits for variation in fibre quality. Individual shipments are tested daily to make certain that they are up to required standards. By continuous liaison with the milling department staffs, the Quality Control Department specifies the required technical controls for fibre production at each mine. In its well-equipped, central laboratory new testing methods are studied, new milling techniques tested, and experimental work on fibre characteristics is undertaken. The Quality Control staff engineers and technicians maintain close relations with the Sales Department in order to help on the spot investigation and solution of customers' problems in the utilization of asbestos fibre and stand ready to provide technical advice and recommendations whenever necessary. In the course of its work on fibre development, the Quality Control Department uses many different testing and control procedures involving such tests as the Ro-Tap, Bauer-McNett, Suter-Webb, Air Analysis, Strength Unit, Surface Area, Wet and Dry Bulk and Oil Absorption. KMX 00468 < ;! ;i 1 i 1 22 Explanation of nomenclature used for LISTING OF A.C.L. FIBRES The Asbestos Corporation is in the unique position of being able to offer to users of asbestos a choice of chrysotile asbestos ex tracted from three different mines, ranging in characteristics from the crudiest to the silkiest type of fibre. Before listing in detail the numerous grades produced at our various mines, an explanation of the numbering system in use is necessary to avoid confusion and promote a clear understanding of its signifi cance. Crudes Asbestos crudes are hand-selected cross-vein material essentially in its native or unmilled form. They are designated as follows: No. 1 Crude: consists basically of crude % inch staple andlonger; No. 2 Crude: consists basically of crude % inch staple and up to % inch; Run of Mine: consists basically of unsorted crudes; Sundry Crudes: consists basically of crudes not otherwise specified. Groups 3, 4, 5 and 6 In all of the A.C.L. milled grades, the first letter or letters of the grade designation indicate the mine of origin; for example: In the grade designation KB-439-4K, the letters "KB" stand for the King-Beaver Mine. Similarly the "N" in N-439-4K for the Normandie Mine, and the "BC" for the British Canadian Mine. Taking KB-439-4K as our example where the "KB" stands for KingBeaver Mine, we come now to the serial number "439". The first digit KMX 00470 i of this number, namely the "4", stands for the Quebec Asbestos Mining Association Standard Grouping for this type of fibre, in this case a group 4 or shingle fibre. Next come the two digits "39" which are used to indicate the character of the fibre as explained below. Finally comes the official Quebec Standard Grade designation, in this case "4K", thus: KB 4 39 4K (King-Beaver Mine) (A Group 4 fibre) (Fibre character) (Quebec Standard Grade) Coming back to the "39" in KB 4(39) 4K, in order to indicate the char acteristics of an individual grade such as our example, a 4K fibre, each grade is given a series of ten consecutive numbers which are used to represent the degree of crudiness or openness of that particular grade of fibre. In our example the grade 4K has been allotted the following series: 39, 40, 41, 42, 43, 44, 45, 46, 47 and 48. Hence we could have any number from (4)39 to (4)48 in this particular grade. In this series, and in all other series used in other grades, the lower number of the series always ends in "9". The final digit "9" indicates that this particular grade, KB-439-4K, is the crudiest type of 4K that can be produced at that particular mine. The higher degree of openness in the fibre the higher the number in the series will be, viz.: KB-442-4K is more open than KB-439-4K but not as open as KB-443-4K. Similar considerations apply in all other grades, for example: BC 1 (British Canadian) 1 BC 3 1 (A Group 3 fibre) 1 3 29 (Crudy) 1 (Open) 33 3K I (Quebec Standard) 1 3K Groups 7 and 8 The classification for shorts and floats follows the same principles as described above; however, other factors such as bulking, grit percentage, viscosity, etc., have a bearing on the nomenclature used. More specific details can be obtained from the Sales Department upon request, and the wide variety of asbestos shorts produced in our mines for various purposes will meet any desired requirements. Note:--The Asbestos Corporation also produces a few grades which carry no descriptive number except for the mine of origin and the grade, such as BC-4T.

"Compiled from data supplied by H. M. Woodrooffe, Industrial Minerals Division, Mines Branch, Department of Mines and Technical Surveys, Ottawa, Ont. and fheir packaging GENERAL By reason of having three different and separate mines our Company is in the fortunate position of being able to supply three distinct types of high quality asbestos fibre according to customer preference. These are: 1. King-Beaver Type Fine, white, silky and strong fibre from our King-Beaver Mine at Thetford is especially adaptable to those processes which call for well-opened grades requiring the minimum of treatment. With the new King-Beaver Mill an even greater variety of quality grades is now available from this plant. 2. British Canadian Type Fibre from our British Canadian Mine at Black Lake can, in the longer spinning grades, be produced in as open a state as that of the King-Beaver Mine. Normally, however, it is made in a crudier state, particularly in Groups 4 and 5 where its high potential value and fast filterability are esteemed by manufacturers of top quality asbestos cement products. 3. Normandie Type Somewhere between King-Beaver type and British Canadian type in harshness, is the Normandie type fibre. Fast filtering and possessing exceptional tensile strength, Normandie fibre generally requires more opening than the other types in order to attain its full value. BAG MARKINGS The illustration at the left is representative of the trade-marked design used on all jute packages of Asbestos Corporation fibre--in this case KB-479-4T. It will be noted that the Quebec Standard Grade "4T" is printed within the "Q" on the lower right hand side, while the Company code number "479" appears in the shield to the left. The name of the mine, in this case King-Beaver, is shown directly under the words "Asbestos Corporation Limited". Every package, jute or paper, bears the Company trade-mark "ASBESTOS" in red as indicated. In the pressure packed paper package the design is the same, but in addition, the grade number is printed on the bottom of each package to permit easy identification in storage. In the case of pressure packed jute packages only where printing on the ends of bags is not feasible, identification of the type of fibre in storage or transit is made possible by the use of a colour code system involving the use of 7 coloured bands placed on the end of each package as shown in the illustration and the different coloured printing of the design. Black Black Blue Green Black Purple Red Blue Green Black Group 3 Group 4 Group 5 Group 6 Group 7 SHIPPING INFORMATION 1. PACKAGING There are four basic packages used in the shipment of Asbestos Corporation fibres each containing 100 lbs of asbestos. They are, 1. Pressure Packed multiwall paper container; 2. Pressure Packed jute container; 3. Loose Packed multiwall paper container; 4. Loose Packed jute container. KMX 00478 Normally, all overseas export shipments are made in jute containers and inland shipments in paper. Economies in transportation and storage costs can usually be effected by the use of pressure packed fibre because of its better stowage and handling characteristics. Compression of the fibre in pressure packed containers on the other hand, may mean cost to some consumers in the opening and prepara tion of fibres prior to use, additional to that normally required for loose packed fibre. Individual package dimensions vary somewhat in accordance with the type of packaging machinery employed and the grade of fibre. Details on this and other aspects of packaging are obtainable from the Sales Department on request. 2. INLAND FREIGHT RATES The Canadian and U.S. railroads have estab lished definite commodity classifications for the movement of asbestos as follows: CANADIAN STANDARD GROUP RAILWAY CLASSIFICATION MINIMUM CARLOAD WEIGHT * 1 and 2 f 3, 4 and 5 6 only !/ 7 and 8 Asbestos Crude 40,000 lbs. Asbestos Fibre < 40,000 lbs. Asbestos Waste 40,000 lbs. Asbestos Shorts 60,000 lbs. Lower freight rates apply on carload ship ments in excess of the minimums shown above to most destinations and substantial savings can be realized by customers by taking ad vantage of these higher minimums where applicable on both domestic and export shipments. Less than minimum carload lots, :1 of course, travel at higher rates. Full informa1 tion on all rates can be obtained upon inquiry I but it should be emphasized that the Company I will always try to ship the most economical way. KMX 00479 I j 3. OCEAN FREIGHT RATES & OVERSEAS EXPORT SHIPMENTS | Overseas export shipments are usually made from the port of Quebec City ! located on the St. Lawrence River or alternatively through the port of Montreal at a slightly higher cost. Both these ports are closed to navigation I during the severe winter months (December to mid-April) due to the freezing I over of the St. Lawrence River, except for a very limited service available ; from Quebec City. Shipments abroad during this winter period are made ( from the Atlantic East Coast Ports of Halifax, N.S. or Saint John, N.B. | at substantially higher inland freight costs. In special circumstances, where prompt service is not available through Canadian ports, shipments can be made from the ports of New York or : Boston but again higher inland freight costs will prevail. Although our prices are quoted on an F.O.B. mine basis, we are prepared to ship on an i F.O.B. port, F.A.S., C. & F. or C.I.F. basis depending on the requirements i of the individual customer. Complete information on prevailing ocean freight ; rates, insurance rates, etc, can be obtained from writing to the Sales Division. ASBESTOS CORPORATION LIMITED President and Managing Director General Manager OPERATIONS DIVISION Asst.
