THE JACK FISH LAKE 
 
 GOLD AND SILVER MINE. 
 
 The property consists of a mineral location on Trhich there is a 
 rich pold ^.nd silver bearing vein and is known as " The Jack Fish 
 Lake . 'ine." It may be more particularly described as mineral loca- 
 tion H \, near Jack Fish Lake, in the township of Moss, in the Dis- 
 trict c Thunder Bay, in the Province of Ontario and Dominion oi 
 Canad 'ysk' containing 160 acren. 
 
 The 
 der Ba 
 
 rty is from 85 to 90 miles from Fort William, on Thun- 
 'm Superior, by the old route. By the proposed new one 
 it is disl nt from Fort William about 110 miles. The Canada Pacific 
 Railway 'o;iv passes within 40 miles of the mine. 
 
 This rii'- vJin was discovered in 1871 but the mine has not been 
 systematica y worked heretofore for various reasons, the chief of 
 which were ohat at the time of its discovery the Indians of the dis- 
 trict had not been settled with by the government, and they forbade 
 mining opera! o^ on a large scale till they were, and during the life- 
 time 0* the lutelCaptain Frue, of Silver Islet, one of the early pro- 
 prietors of the \nme, there were no Railway facilities. But now the 
 Indians are settled with by treaty with the government, and the 
 Canada Pacific Railway is constructed from Fort William to Winni- 
 peg. It was advertised to be open for traffie on the 18th of this 
 present month of September, 1882. 
 
8 
 
 The most convenient access to the mine now will be via The Can- 
 ada Pacific Railway from the town plot of Fort William to Savanne, 
 a distance of 70 miles ; thence by boat, via Savanne River and Lac 
 des Milles Lacs (which are both navigable), to Barril Portage, about 
 25 miles ; thence by road to be made to the mine, a distance of about 
 15 miles. Savanne can also be reached now via Winnipeg and the 
 C. P. Railway. 
 
 The title to the property is derived by patent from the Crown and 
 subsequent conveyances in fee simple. It is held free from incum- 
 brances and is not subject to royalty or other crown dues on the 
 minerals. 
 
 At the instance of the late Captain Frue, who became a purchaser 
 of an interest in the property shortly after its discovery for a large 
 sum of money, the mine was examined by Mr. Walter McDermott, 
 Mining Engineer and late Assayer of the Silver Islet Mining Com- 
 pany, and his report is printed herewith. 
 
 By the more recent report of Mr. Peter McKell/r, of Fort William, 
 Mining Expert and Geologist, and the certificates from the two well 
 known Metallurgical Houses in New York, Messrs. Ledoux & Rickettsj 
 and Messrs. Mathey and Riotte, published herewith, the results of 
 thorough practical tests are shewn. 
 
 The report of Mr. McKellar, and the certificate of Messrs. Ledoux 
 & Ricketts (No. 1), shew that a sample of the high grade ore from 
 this mine yielded on assay at the rate of !$5,97L60 per ton of 2,000 
 lbs., or gold $4,752,03, silver $1,219.57; and by the same report and 
 the certificate of the same firm (No. 2), it is shewn that by a large 
 assays, after crushing and sampling a whole ton of the average ore 
 ot this mine, the averagje ore yielded at the rate of $49.28 per ton, or 
 gold $36.30, silver $12 j(8. 
 
 The certificate of Messrs. Mathey & Riotte (No. 3) also referred to 
 in Mr. McKellar's report shews the ore to be free milling ore, and that 
 the tailings can be concentrated to advantage afterwards. By Mr. 
 McKellar's report and Messrs. Mathey & Riotte's tests and certificate 
 it is shewn that a ton of the average ore of this vein yields by free 
 millii-g at the rate per ton of $26.24 gold, and that the concentrated 
 
tailingfl are worth $82.43 per ton of concentrated ore or gold $76.62, 
 silver $5.81. 
 
 Mr. McKellar's report and that of Mr. McDermott contain a de- 
 scription of the property and estimates of its capabilities and from 
 these the character value and prospects of the mine can be judged. 
 
 REPORT OF MR. WALTER McDERMOTT, 
 
 JACK FISH LAKE LOCATION. — SHHBANDOWAN. 
 
 In the winter of 1872-3 in company with Captain Frue, I visited 
 the Jack Fish location, which is situated about 85 miles west of 
 Thunder Bay, Lake Superior. 
 
 The gold-bearing vein, on which some little work had then been 
 done, is situated on one side of, and running parallel with, a narrow 
 valley formed by walls of granite on the one hand and green stone 
 on the other. The vein itself rests on the granite wall but with an 
 interposing thin belt of talcose slate preventing actual contact. For 
 several hundred feet on both sides of the principal working, the vein 
 has been traced, but as the period of my visit was mid-winter, with 
 its customary heavy covering of snow, my personal observations were 
 confined to the points at which work was actually in progress. At 
 different points of the principal opening, the vein varied in width 
 from 2 to 7 feet, and consisted of quartz, with occasional patches of 
 yellow magnesian spar. The minerals contained in the gangue were 
 principally copper and iron pyrites, light colored zinc bleude, galena, 
 and with varying small proportions of free gold and sylvanite (telluride 
 of gold and silver). The sulphurets appeared from a number of 
 assays to carry always a small though variable quantity of both gold 
 and silver, the two metals maintaining a pretty constant relative 
 ratio ; and occasional streaks of the mixed sulphurets, differing but 
 very slightly in appearance from the bulk of the mineral, yielded quite 
 richly on assays. The occurrence of the free gold and sylvanite, 
 generally, though not always, in conjunction, was irregular but not 
 
infrequent ; for during the three days I remained on the spot, several 
 separate blasts developed rich portions of the vein, from which many 
 very fine specimens were obtained, showing free gold in strings, 
 spangles and small nuggets, and streaks, coatings and small 
 masses of the extremely valuable sylvanite ore. This sylvan- 
 ite was first misjiaken by the miners for silver glance, but 
 assays and analyst proved it to be the true telluride of gold and 
 silver, some samples of the sulphurets through which it was mixed 
 yielding on assay up to $4,000 per ton in gold and silver, chiefly the ' 
 former. From some few barrels of the ore taken to Silver Islet, 128 
 k. lbs. of reck was selected and sent to BalbacJ^'s smelting works in 
 New Jersey, the works returning as a result a small brick of silver 
 and button of gold, weighing respectively 6^ and 1.16 oz. 
 
 Of course it is not to be supposed that so high a result represents 
 the average of the rock ; nor does it any more represent the best that 
 could be obtained, since a little more rigorous selection of the sample 
 sent could easily have made the latter yield double or quadruple 
 the percentage of gold and silver, as any person will understand when 
 it is understood that many samples could be selected carrying free 
 gold alone or with the rich sylvanite. 
 
 A road has been cut through the woods, a distance of 12 miles, and 
 connecting the mine with Lake Shebandowan, and thereby with the 
 Bed River Road to Thunder Bay, the route of the Northern Pacific 
 Railroad branch, at present in process of construction. The immedi- 
 ate neighborhood of the mine is heavily timoered, the trees being of 
 good gro'vth and various qualities, offering everything in the way of 
 timber supply for mining purposes. The occurrence of the soft 
 talcose slate on a hard wall is very favourable for the breaking out of 
 the vein, and leaving a good wall requiring hardly any timbering.

 REPORT OF MR. PETER McKELLAR. 
 
 THE JACK FISH LAKE MINE. 
 
 The Jack Fish Lake Mine, consists of a block of land half a mile 
 square, containing 160 acres, with a rich gold and silver bearing lode 
 running diagonally through the property near the middle. 
 
 This rich vein was discovered in 1871 and was the first known free 
 gold discovery on Lake Siipei-or. The following year, the many 
 rich gold and silver specimens hiken from it and distributed all over 
 the country, created much excitement. At the time that section of 
 country was in the possession of the Indians and they strongly ob- 
 jected to any improvement being made by the whites until a treaty 
 was coniiiummated. Besides that, the access to the mine was 90 
 miles of alternate stretches of land and water, which would render 
 the cost of transportation of machinery and supplies very great. 
 For these reasons it was decided by the owners, to let the mine rest 
 until thene obstacles were removed^ <,^Ain Captain Frue, of Silver 
 Islet, who had purchased a half interest in the property immediately 
 after its discovery for $20,000, was not alive to prosecute the work 
 of the mine when these difficulties ceased to exist. 
 
 I may mention, that altho igh, following its discovery the vein was 
 well examined by mining crosscuts and excavations, yet, no practical 
 test was made to ascertain the value of the average ore. At one 
 place 10 feet were sunk, and about 100 tons of ore blasted out which 
 now lies on the dump. From this, some of the richest ore only was 
 taken away, of that, the best was distributed amongst friends and 
 specimen hunters all over the country, the balance 123 lbs. was sent 
 to Balback & Sons, Newark, New Jersey, and smelted. It yielded 
 $517.98 to the ton, or gold $396.80, silver $121.18. The button of gold 
 produced wcoighed 1.16 oz., value $24.60. It is now in the possession of 
 Mrs. J. Molntyre, of Fort WilHam. Many assays were made of the 
 different kinds of ore in the lode with varying results from a trace up 
 to thousands of dollars to the ton, but no test was made with a view to 
 an approximation of the real value of the lode or to find out by which 
 
6 
 
 prooess it would work to the best advantage until lately, so that it 
 was, to a certain extent, enveloped in uncertainty. 
 
 Now the obstacles to the working of the mine are removed. The 
 Indians have been settled with by treaty with the government, and 
 the C. P. Railway was opened for business on the 18th of this month. 
 Savanne, one of the railway stations 70 miles from Thunder Bay is 
 connected to the mine by about 25 miles of water on Lac des Miller 
 Lacs to Barril Portage and 15 miles by land between Barril Portage 
 and the mine. Again the complete tests hereafter referred to made 
 by the two leading metallurgical works in New York of a ton of the 
 average ore from this lode prove beyond a doubt that it is a mine of 
 great value and that it will require but a comparatively small amount 
 of money to make it begin yielding returns as will be shewn further 
 on. 
 
 GENERAL FEATURES. 
 
 The property consists of flat, mossy, low land with undulating 
 rocky ridges covered mostly with sandy soil suitable for grain and 
 roots. Both high and low are well covered with the usual timber of 
 the district, suitable for raining purposes; there is also a small 
 stream of water running within 50 to 100 feet of the lode in an ad- 
 mirable position, for supplying the stjimp mill for washing purposes^ 
 For the most part of the year there is plenty of water, and with a 
 small expenditure, it can be made to supply all requirements for all 
 seasons. 
 
 CHARACTER OF FORMATION. 
 
 The rocks on the location consist of semi-crystaline greenish slates, 
 talcose, chloritic, dioritic, &c.,with massive diorite and silicious mag- 
 netite, all interbedded and conformable with one another, and dipping 
 at a high angle 60'=' to 80^ towards the N. W. About a mile to the 
 N. E. these strata, are displaced by an intrusive syenite, an allied 
 rock to granite, in which the bed of Jack Fish Lake is cut out, and it 
 is probable that to the presence of this intrusive syenite, the exist- 
 ence of this gold vein is due. These rocks belong to the Huronian 
 series. Professor R. Bell in bis report of the mineral bearing rocks 
 of Lake Superior which appeared in the " Globe," March, 1874, 
 states, "The gold of British Columbia and other regions occurs in 
 rocks similar to those of the Huronian series." 
 
 t 
 
CHARACTER OF VEIN. 
 
 I have examined this lode at various places for a distance of about 
 2,000 feot on this location. It is subject to expan ms and contrac- 
 tions like other veins, but on the whole it appeara to uo 6 to 8 fee* 
 wide within the walls consisting of quartz with a central belt of soft 
 talcose slate, two to four feet wide charged with iron pyrites and some 
 gold, which may pay to work in places. The vein dips N. W. at an 
 angle of about 75® to the horizon and bears north eastward, cutting 
 the strike of the slates at a small angle. On either side it is bound- 
 ed by greenish slates that are more or less talcose in character. It 
 is an undoubted true fissure vein, and gold veins that carry much of 
 p the sul/hurets like this one are considered as reliable for carrying in 
 depth as fissure veins of other metals. 
 
 The quartz are 2 to 5 feet wide, charged with galena, iron and 
 copper pyrites, zinc bleude and the sulphuretsof silver and tellurium 
 with spangles and grains of gold large and small disseminated through 
 the whole in more or less quantities, but more plentiful along with, 
 and in the vicinity of the ores of silver and tellurium, which make in 
 bunches here and there through the vein. These bunches yield sev- 
 eral thousand dollars to the ton and are likely to be found in places 
 large enough to be worthy of being called ** bonanzas." For result 
 of an assay of the high grade ore see certificate of assay of Ledoux & 
 Eicketts (No. 1). Independent of this rich ore, the balance of the 
 quartz shows an average yield of $45 to $50 to the ton, and by the 
 thorough tests lately made of the ore in a large way $26 of gold to 
 the ton can be taken out by the free milling process or copper plates, 
 which can be cheaply worked. Ten dollar a ton ore, free milling 
 would pay well at this mine. In Australia, mines are worked at as 
 low as $3.00 a ton and pay 10 per cent, on the capital invested ; but 
 of course this is under very favorable circumstances. In the Black 
 Hills of D4liota, ore yielding 6 to 8 dollars when free milling is 
 worked very profitabl;^. 
 
 THE TESTS. 
 
 This summer I was engaged to have a fair average test of the 
 ore of this lode made. I took a gang of men and proceeded to the 
 mine. All the exposures of the vein were examined and I found the 
 
8 
 
 vein stone remarkably uniform in charactGr. I made several tests ot 
 the ore from various points on the vein by pulverizing, roasting and 
 washing which shewed considerable gold ; some tests shewing coarse 
 gold. In making these tests I did not select ore shewing gold to the 
 eye ; and some of the samples were of the lode near the middle of the 
 location and others from the portion near the southern boundary, 
 1,300 feet apart. 
 
 I also took out a ton of the average ore, half of this ton was blast- 
 ed out of the bottom of the principal excavation (f'om which the 100 
 tons referred to were mined) at a depth of 11 feet. I took it as it 
 came without selection. The other half ton was taken out in the 
 same way from the surface at a point on the vein where it enters the 
 valley, 60 feet to the S. W. ; here the quartz is 5 to 6 feet wide. I 
 took this ore to New York and had it tested by two leading 
 metallurgical firms Ledoux & Eicketts, and Mathey & Riotte. 
 The former crushed the whole ton and sampled it with much care 
 down to 200 pounds ; this they put through another finer crusher and 
 sampled it down to a few pounds, and made two large assay tests 
 which shewed an average of close on $50 to the ton. See their cer- 
 tificate (No. 2). Then I took 250 pounds of the first pa>"t sampled. 
 I sent this quantity to Mathey & Riotte to have it tested in different 
 ways, and also to see how the two would compare. They ground it 
 fine, sampled and assayed it, the yield shewing $46.80 to the ton. 
 
 Then they stamped it and run it over the copper plates, which 
 caught $3.28 gv M, or a yield shewing $26.24 to the ton. The tail- 
 ings w-^re then assayed and gave an average yield of $20.26 to the 
 ton. In this test, as will be seen by their certificate (No. 3) it 
 shewed an average of $40.06 of gold to the ton independent of the 
 silver of which there was a considerable loss. Then the tailings 
 were run over Frue's vanners and co\centrr.ted to 11 4-10 per cgnt. 
 or about 8| tons into one. The concentrations assayed $82.4/ to 
 the ton, that is an average to the ton of ore of $9.42, which, with the 
 $26.4^ saved on copper plates, makes $35.66 saved by milling. 
 Assays of the balance shewed a loss still in the tailings of $9.42 to 
 the ton. The test was made by a small vanner, I believe the large 
 vanner will do much better work. Mr. Goldsmith, the manager of 
 the works said the ore was good ore to work and that a large mill 
 
 ll

 9 
 
 would easily show as good or better results from the same ore. I 
 was present in New York and saw these tests made. I am convinced 
 of their tLoroughness and correctness. 
 
 ROUTE TO MINE. 
 
 In regard to starting the mine, I would advise taking in the 
 machinery and supplies by way of the railway to Savanne, thence by 
 the chain of lakes and Dawson's Portages to the head of Lake 
 Shebandovvan, and thence over the old road, cut out several years 
 ago, 12^ miles to the mine. By this route, a passable winter sleigh 
 xoad can be made available at a trifling cost for the first winter's use. 
 The machinery should be taken to the mine in January, when the ice 
 is good and before tht> snow gets deep. This route could not be used 
 to advantage in the summer, but by spring the new one by Barril 
 , Portage could be opened out for traffic — the latter consists ofone 
 
 OH stretch «if land and one by water to the railroad. 
 
 COSTS OF OPERATING THE MINE. 
 
 I would recommend starting the mine on a basis of 14 tons a day 
 by using two batteries (10 heads) of stamps with copper plates foy 
 catching the free gold attached. Also two of Frue's vanner's for 
 concentrating the tailings from the free milling process. As shewn 
 by the tests, the copper plates would catch about $26 per ton gold, 
 bullion, cash on hand as produced, which of itself would far exceed 
 the expense of operating the mine. The product of the concentra- 
 '^" tions at $82 per ton after all expenses in connection with shipping and 
 
 treatment were deducted would yield an additional profit of about 
 $35, per ton of concentrations equal to about $4 to the ton of ore. 
 In a short time the mine would be self-sustaining, and in less than 
 6 months it would be able to pay back all the working capital invest- 
 ed. Its capacity should be increased as results would justify. I 
 have made enquiry as to the best machinery and the cost of the 
 same. I have also made close estimates of the cost of getting the 
 machinery and all necessary supplies to the mines, and also of the 
 cost of operating, and of the yield of bullion from the mine, which, 
 as near as I could calculate, would be as follows : 
 
 Allowing that work was cDmmenced by the first of {December, the 
 
10 
 
 mine equipped and operated for six months on the above basis of 
 14 tons a day, with a further supply of all material and provisions 
 to carry on the work for another two months on hand, (the latter 
 supply being necessary until the road to Barril Portage would be 
 ready for the summer's work), then, the returns and expenditure for 
 the first 6 months would be as per Schedule A, as follows :

 The next year succeeding the first 6 months, carrying the above 
 balance down, and continuing the mine on the same basis, the re- 
 turns and expenditure for the year, I estimate, from the showing of 
 the tests to be as per Schedule B, as follows : 
 
 Balance carried down from first 6 months $32,974 
 
 Keceipts from the mine, 1 year 126,000 
 
 $158,974 
 Permanent improvements to be made this year.. $11,000 
 
 Other expenses for the year 29,395 
 
 40,395 
 
 Net profits at the end of the 18 months $118,579

 Should the mine continue as the showing now is its capacity coulJ 
 be raised to 100 tons a day, and in the event of which, approximate^ 
 estimates of product and running expenses for a year would be as 
 follows : 
 
 Bullion product of mine, 1 year $900,000 
 
 Expenses of running mine, 1 year 175,000 
 
 Net profits for the year $726,000 
 
 The above estimates show a mine of great value, and when worked 
 100 tons a day (which is not by any means the extent to which it 
 could be raised), they show that the mine would pay over ten per 
 cent, dividend on $7,000,000. I do not think the estimates unreas- 
 onable considering the size of the v'>in and the yield by the test in 
 New York of a ton of the veinstone unselected. 
 
 These tests showed a value in the ton of nearly $50. In the above 
 estimates I calculated that only $35 would be saved by milling, and 
 there is no allowance made for the rich ore which is worth some 
 thousands of dollars to the ton. This rich ore is found in bunches 
 through the vein and considerable quantities will at least be found 
 during a year's work if not great "bonanzas." 
 
 It is a fissure vein, and I see no reason why it should ijot carry 
 its size downward as far as mining can go. It is as likely to become 
 larger and richer as it is to get smaller and poorer.. The richest 
 showing ever made in a vein was at the depth of about 2000 feet, that 
 was the great bonanza in the "California" and " Consolidated Vir- 
 ginia," on the " Cumstock Lode." The " Calumet and Hecla" mine 
 is richer at 3000 feet down than it was at surface. Working at 100 
 tons a day, the Jack Fish Lake Lode, allowing it carries its size, 
 would not be worked out to that depth in 40 years. 
 
 In conclusion I may state I firmly believe that the Jack Fsh Lake 
 minea^will prove itself to be one of the rich mines of America.

 Mr. Peter McKellar, 
 
 Fort William, Ont. 
 
 Sir, — 250 lbs. of your ore crushed, sampled and assayed, proves 
 to contain 
 
 Per assay No. 3818, Gold $32.66 per ton. 
 
 Silver 14.14 " 
 
 The ore was run through a stamp battery and the gold caught upon 
 amalgamated copper plates, yielding 160 grains of bullion 477 fine, 
 value $3.28, equal to a yield per ton of $26.24 in gold. 
 
 The tailings were caught, sampled and assayed, and !)rove to con- 
 tain per assay No. 3819, gold $13.82 per ton, silver $6,44 per ton. 
 
 The tailings were concentrated on a True Vanner, yielding 28^ lbs. 
 or 11.4 per cent, of concentrates, which prove to contain per assay 
 
 No. 3824, gold $76.62, silver $5.81 per ton of concentrates. 
 
 «■■ 
 
 The tailings after concentration, sampled and assayed, still prove 
 to contain per assay No. 3820, gold $6.28, silver $3.14 per ton of 
 tailings. Very truly,
