V DESCRIPTION. The Joe Howe Mines are situated at Smithfield, in Colchester County, in the Province of Nova Scotia, fifteen miles from Truro, the County seat. Brookfield Station on the Intercolonial Railway, about 48 miles by rail from the city and harbor of Halifax, is the best point from which to reach the mines, the distance being thirteen miles by a good carriage road. The Stewiacke Valley and Lansdowne Railway will, when completed, run within two miles of the mines, and a connecting siding could be laid at small expense. The property consists of 143 mining areas, (each area containing seven-eighths of an acre), and extends for up- wards of two miles along the limestone formation which contains the ore, and is from 750 to 1000 feet in width. The mines extend east and west along the south slope of a valley, and are cut across by several small and rapid ])rooks, which empty into the stream flowing through the valley below. These brooks drain a lake on the level above the mine, and could be made to yield good water power. TrrLM The title is perfect, being covered by leases for silver bearing ores, and also by a five mile right of search for lead, etc. Considerable prospecting had been done on the pro- perty when it was visited by the Inspector of Mines in 1884, and below we print his report, only omitting his description of the location of the mine. Repoiit of Ejjvvix Gilpin, Jr., A. M., F. G. S. Deputji Comm'mioiwr and Inspector of Mines for the Province of Nova Scotia, f Member of the North of England Institute of Mining Engineers, tic.) Halifax, July cth, 1884. DBAR SIR; I beg leave to hand you the following report on the Smithfield mine. The property contains 143 areas, each 250 by 150 feet, and extends, rslaid out by the Government Surveyor, 6000 feet along the general course of the mea- sures, viz., N. 75° W, The measures holding the vein belong to the Mountain Limestone seres of the carboniferous period, and are the equivalents of the same series as found in England and elsewhere. The work hitherto performed has been almost entirely t t confined to that part of the property which lies east of Henry Smith's house. Here a small prospecting shaft was sunk Ixjside the road, and the ore exposed, llie second shaft was sunk about loo feet east of the road. This shaft was 35 feet deep, and a cross cut driven through the ore body from the foot wall. The shaft showed ore, which was also found for 30 feet in the crosscut. The ore is made up of carbonate of lime, carrying galena, with iron pyriteF. The third shaft was sunk 450 feet from the road, and is about 55 feet deep. In it the ore was of similar qua'Hy to that met in the second shaft, but of better quality, the lead being more concentrated. The fourth shaft was sunk to the top of the ore, I am informed, but it was not open at the time of my visit. The second and the third shafts are timbered, and could be used for raising ore, etc. At Samuel Pike's house, 1950 feet west of the first shaft referred to above, were found the first indications of ore, which led to the prospecting which disclosed the deposit described above. About 1500 feet further west a prospecting trench showed float ore, and galena was observed in small quantities in a limestone band. I men- tion these discoveries, as they apparently indicate that the ore-bearing band extends through the greater part of the property. The area is, undoubtedly, a very promising one, and the small amount of work hitherto performed has shown a good value. The ground already proved to carry ore I extends over 450 feet in length, the width of the ore ground may be estimated at 30 feet, the tunnel carrying ore at the face when discontinued. I find on looking over the notes of my first visit to the mine that I estimated the proportion of No. l galena ore that could be hand dressed out of the ore at 16 per cent., and do not see any reason to change this estimate. This would give in the ground already opened about 25,000 tons of galena. This would be ref».dily extracted at a very cheap rate by an open cut, permitting the use of steam for power drills, and of a whip for raising the ore, in fact quarrying. During this extraction, work could go on, preparatory to mining operations in the lower part of the mine. The district is favorably situated for carrying on mining operations, as there is abundance of timber in the vicinity, good roads, and water power within a few yards of the mine, 6-c., ^^c, &>c. And the district for miles to the north of the mine is heavily timbered. These notes will convey all the information I have about the property, and you are in possession of the assays and analyses that have been made of the ore at various times. I have always had a high opinion of the property, and consider it well worth opening up, and am pleased to learn that arrangements are proposed to that end, as it promises to prove the inauguration of an important addition to our mining industries. I remain, yours very truly, Edwin Gilpin. * A I 9 .i SITPPLEMENTAL REPORT. Halifax, August 7, 1884. Dear Sir, With respect to my memo, on the Smithfield Lead Mine, addressed to you under date July 5th, 1884, and to your (luery as to the correctness of the statement in it as to there being 25,000 tons of available galena, I beg leave to remark : My estimate is based on my examination of the dumps at the time of my first visit, by comparing the ore raised with the excavation made, and the examination of its freedom from stone, etc. I calculated that from the deposit as it stood in the ground 16 per cent, of ore could be dressed out. Calculat- ing the length of ground at 450 feet, the depth at 50 feet, and the width at 20 feet, I estimated the amount of ore as equivalent to a vein 450x50x5 feet or 112,500 cubic feet, and that 4-5 feet made a ton, or 25,000 tons of galena. It may be considered that the grade of the ore, as calculated above, is placed at too high a rate; it was reckoned on ore practically free from pyrites, etc. Taking, however, one-fifth from the above amount, I feel that the figures of 20,000 tons would be under the mark, so far as I would form an opinion. I remain, yours trulyi E. Gilpin. 10 Mr. Douglass Browne, a miner of considerable exper- ience in Mexico and the West, visited the mines at about the same time as Mr. Gilpin, and below will be found extracts from his report. Eeport of Douglass Browne. » ♦ ♦ In consequence * * and the favorable opinion expressed by those who had seen the property, I was induced to visit it, and was much impressed by the indica- tions of a large and valuable deposit of lead and silver ore. A sum of from $8,000 to $10,000 has been spent in prospecting and opening up the property, and to-day it gives promise in my opinion of becoming one of the largest lead producing mines in the world. Having had 16 years experience in practical mining in several of the most important mining centres, I feel justified in forming and stating my opinion, and more especially as the same views have been expressed by several competent mining experts, who have examined these mines, cr'C, tS-^c, cSr'C. DEVELOPMENT. Besides the surface prospecting, lour shafts have been sunk, varying in depth from 35 to 60 feet. These shafts have proved the ore body to extend 6co feet in length. A cross cut in one of the shafts has been run 35 feet, all in the ore body, and no wall yet reached ; the vein is a brackish one, and, in every instance as the shafts were sunk, the ore was found to be increasing in purity and quality. Tke last y r 11 15 feet of the deepest shaft, a shaft 5 ft. x lo ft., gave 30 tons of ore. The ore occurs in the vein in solid kimps of galena, varying in weight from a few pounds up to several tons. Taking the surface and as far as yet opened, solid ga'ena constitutes at least one tenth of the whole vein, e^c, 6-c., cr'c. And, in order to extend the development further, the necessary capital is required to erect smelting and reduction works, which the present showing amply warrants ; the indications being that 50 feet more in depth sunk on the shafts would show a solid vein oi galena with all the lime and other vein matter eliminated. The assays made show the ore to contain 50 per cent, of lead, and besides to yield from $s to $100 of silver, and from a trace up to 6 dwts. of gold per ton of 2000 lbs. PROSPECTUS. The trade and navigation tables of the Dominion of Canada for the year ending June 30th, 1883, show that over ?2o,ooo in duties was paid on scrap and pig lead, imported during the year. The total duty paid on lead and its manufactures being upwards of 832,000, as follows, viz. ; Old scrap and pig imported, $48,780 cost. Duty, $19,523.79 Bars, blocks <2r' sheets " 28,785 '' " 5,156,46 ^^^^^ " 10,655 " *' 3i285.'95 Other articles «« .. 4,306.15 $32,272.35 12 For practical calculation, it may be said that the duty on importing lead into the Dominion of Canada is $8.00 per ton. And, as yet, no lead mine being operated in the Province of Nova Scotia, we' have the benefit of this duty. The virholesale market value of lead in Halifax, Nova Scotia, is $90 p-r ton. In New York City it is from $60 to S70 per ton. A glance at the map will shovir that the production of lead once established at or near Halifax, would enable the owners to outrival all other Canadian and American competitors, who are further west, in supplying the European and local markets, and as the great lead mines of America are chiefly in the far West, the greatly increased cost of labor, material and transportion there, over a mine situated in Nova Scotia, will enable the owners of this mine to defy competition from them even in the chief Canadian and American cities. In Nova Scotia material of all kinds necessary to prosecute mining is very cheap, and labor is low. 'i he daily wages of the best miners are from 1^1.25 to $1.40 per day. Fuel, such as coal, coke and wood, also all lumber required for mining purposes, is plentiful and moderate in price. I add a statement of what might be expected as profit, from the erection of a smelter with a capacity of 30 tons of ore per day, which, with silver and gold extracting plant, could be put up at a cost of $25,000, namely ; 13 Cost of mining and delivery 30 tons of ore at the smelter.including superintendence and dead work, 6-c $240.00 Smelting $10,000 per ton, 300.00 Freight on bullion .... y^ 00 ^615.00 PROCEEDS. 15 tons lead bullion worth in Halifax $190 Pe^'ton ^j^^o Silver per ton of bullion.'at 3 ..00 §450 ,800.00 Nett profit per day Si 185.00 Your obedient servant, Douglass L. IJrowne. WoKKs Conducted Under the Management OF Douglass Browne. Mr. Browne, in conuinction with two other gentlemen, secured a years bond of the property, and they could have sold out at a high figure to an English Company, but concluded to put up a smelter and work the property. A gentleman in Halifax agreed to raise the capital necessary to erect a small smeltimr worlc;. aiwl n mnf-iii»^,^;^f r„„,^ Swansea happening to be in Halifax, he contracted to put r4 up works that would successfully treat the ore. A few thousand dollars, an entirely insuftkient sum, were raised and a small smelting plant hurriedly erected, ihe promoters of the enterprise expecting to pay for the fuither develop- ment of the mine by the sale of the --oduct from the smelter. They were doomed to disappointment, as the smelting works proved an entire failure. In this dilemma Prof. Richards, of the Institute of Technology in Boston was appealed to, and, on his recommendation, Mr. Walter J. Koehler, a thorough metallurgist, was employed to investigate matters. He found that some five thousand dol- lars were required to complete the works, and that the ore was easily smelted, bnt, as the promoters had exhausted their capital, the works were shut down, and, owing to some slight entanglements, (which have only now been cleared up), nothing has since been done on .this valuable property. Rkpout OF Walter J. Koehler, 8. B., Metallurgist. . Middle Stevviacke, Feby. 4th, 1885. Dkar Sir, At your request I came here three weeks ago to examine the smelting works connected with the Smithfield Lead Mines, and to report upon the proper method of treating the ore. 15 From the analyses I made, the following is the average composition of the ore as delivered from the mine to the smelter : — Insoluble resiciue. 2.6 per cent. Sulphide of Iron.. 25. 5 " containing..! 1.9% Iron. *' Zinc. 13.5 <* «' 9.0 Zinc. *• Lead. 42 8 ** «' 37.2 Uad. Carbonate of Lime 9.6 " *» 5,4 Lime. " Manganese 2.7 " «« 1.4 Manganese. Total 96.7 The composition of the ore presents nothing to hinder its successful and profitable treatment. The proper method of treatment would be as follows : 1st. Roasting in a reverberatory furnace. 2nd. Smelting the roasted product in a blast furnace. 3rd. Softening the resulting lead in a reverberatory furnace, or possibly in a pot. The approximate cost of these operations would be as follows : 1st. Crushing preparatory to roasting per ton $ .60 Roasting 1.60 2nd. Smelting, with present furnace 3.50 $5-70 Allowing that 12% of the lead in the ore were lost during the melting, which, however, would be reduced by proper condensing arraigements to 7 or 8%, 3 tons of ore 16 would protiiice one ton of learl ..rh; u per ton of unrefined lead to ^To' ""'' ''"^ '''^ ^^^' 3»cl.

Estimate of t> e \'alue of the Ore now Developed ox a Lead Basts Only. Mr. Browne's estimate cf the cost of mining and delivering ore at smelter, including superintendence and dead work, etc., etc., equals $8 perton, (a very high average). Mr Koehler estimates that 3 tons of ore will produce one ton of unrefined lead. 1 A ^^u T^ f Producing one ton of 2000 lbs. of refined lead will therefore be as follows : Cost of mining and delivering 3 tons of ore at smelter ^ Cost of roastmg same in kilns and smelting as per Mr. Kcehler's estimate $10.66 Refining ** • ••• 2.00 12.66 Total cost of mining and smelting i ton refined lead ^^^ ^^ ■r, . . , ' • ' ^30.00 Freight on same to Halifa.x .... - ^^ 19 Total cost of mining, smelling and delivering one ton refined lead at Halifax .... -..,..

In fact, one of the most reliable houses in the Dominion of Canada, doing business at Halifax, "-ould purchase the entire output of the smelter at the rate of I60 per ton, delivered in Halifax at present market value In addition to scrap and pig lead, there was imported in 1886 9,40s cwt. sheet and bar lead, 503,1,7 lbs. shot, and 92.352 'bs. acetate and nitrate of lead.
