Thompbon, Ebq., ) Boston, Mabs. ) *' ,Mt Dear Sir: ■ I hâve made a hasty inspection of the "Hartford Mine," near Sherbrook, Canada, and ÎJeg îeave, herewith, to présent my re-« port of the same : — • " " The Iode Is^^ontained in a glossy, piye-grained slate, befong-' ing to thfi "Québec Group" of the Canadian Qeological Survèy. Portions of this rock (MsintegraBe-with rapidity when etposed to the air; other portions remain flrm and solid. 8t)ecimèiis of the slate hâve been found, on examinafion, to coytain great numbers^ of small crystals of -pyrites ^jaseminateà through the mass. This^ rock bbs a variable strike, being much twisted in its stratiflcatioia. At theinine it runs nearly east and west and dips at a njoderate but varying angle to the south. tt is intersected by vertical dykes of eruptive material (metaphyr), which run east and virest, and in- tersect both country rock and Iode without much disturbing either, so far as I had opportunity to observe. When the dykes bave branched so as to include a portion of the Iode, tlffs retains its natural appearance. ■ ^^ The Iode appears.toie whàt k called, inlhi» country, a "8e- gregsted Vem" of mass; that is to say, a deposit of metallife- • . ) . - ". V. T -A- N-tii* ""ifii^ ^ »*^^-^f%ï ¥ « ,, rouB material lying pretty nearly in the plane of the stratification or^amination of the encloaîng country rock, and not separated by well-deflned flucan selvages or other ordinarîly observed indi- cations of a prefixisting fissure. In some places, however, a tolerably sniooth wall does |xtend for some distance separating, or indicating a séparation between the Iode and the countiy. In gênerai, the outline of the mâss of ore, in a direction at right angles to the run of the Iode, or in a transverse section on the dip, is very irregular. The gênerai character of the ore body, however, is that of a flattened mass, dipping Mjith the formation, having a length along the strike of the county rock of from one hundred to two hundred feet, and à thickness of from six or eightto thirty, or even more, feet. This mass bas been foUowed down in Shaft No. 6 as far as the eighty-flve-fathom level, and the character of the Iode has been found to be essentially the same from top to bottom. The dip averages about thirty degrees, and is in a south- erly direction, tlie shaft carried down on the dip of the Iode having almost exactly a southerly direction, (magnetic, the varia- tion being sixteen degrees west). Shaft No. 5 appears to be on the western edge of the ore body ; at ail events, the workings hâve been entirely confined to the région east of No. 6. It would look as if the ore had been eut ofE on this side by a "fault" or heave ; but I was unable to assure myself that such had been the case. Prom the best information I could obtain, about seventy- five thousand tons of ore hâve been taken from this mine, which would indicate, as the average dimensions of the shoot of ore worked, about one hundr^ fbet in length by ten in thickness. r ■ • n ■.. ^ • 1 r ' ■ b-' / . 1 .1 . ' , P- V / ^ j, *^,&.'ltjjj, "^^.^Wï-À . .}J ,•»-«. AN ^fif^î^imitU 4-.. 9 The character of the ore is extremely uniform as exposed in the mine. It is a vast body of iron pyrites, with a small per- centage of copper contained in it, and almost: or quite entirely free from any admixture of gangue or vein-stone. It is a metalliferous mass bf very remarkable dimensions and freedom from minerai matter. Unfortunately its ténor in copper is net high, as is evidpmt from inspection. Its actual yield could, of course, only^ptold after assay, as low grade copper ore cannot ,be estimated with any approach to accuracy by the eye alone. It is said to hâve yielded by tlie " Henderson Process," in the wet way. fouf-and-a-half per cent, of metallic copper, on the average. Spécimens of a higher grade ore were shown me as having come from the part of the mine j»ow undei; wster, and you hâve the authority of Capt. Bray as establishing the fact. , j The inference to be drawn from the facts observed, and the information gathered from reliable persons, seem to be that there is hère a very large body of low-grade copper ore which bas been already worked to a considérable depth, and which is likely to hold for a considérable distance downwards. Several consid- érations support this viéW. In the fltst place, the ore-body is so large that it would seem to be highly improbable that it should come to a sudden tennination. In the next place it would ap- pear from the facte gathered that where the Une of the "Crown" properly crôsseB tfie Iode (which in the shaf t is a little below the seventy-three-fatho^ level), thera^is no falling off in the dimen- sions of thjB mass; but, if anything, an increase, the workings being fully two hu^dred feet long on the Une of the "Crown" property. / »i^. l'^j.-t'/* • *" .''**>''^^^î«^*~-;^4*»;4^^'^r^ '«^i^vfit-.iji -r* K\^.j'^\Vi^Ms^di - ^■a x ■ 10 Had not the weather and an accident prevented my making an examination on the Une of outciop ortlie Iode, I shoujd hâve got additional, and, I présume, valuable testimony as to its charac- ter for permanence. The lo(ie is said to liave an extensive linear development, and that I j^hould regardas an important élément in judging of its holding in depth. It has alsô become a question whether there are not other chimnies or shoots of ore on the Iode, of extent and value enough to be worked. and which may be richer in copper. The question seems to be narrowed to a mctallurgical one; namely, whetlier a low grade copper ore occurring in large quan- tities, and under very 'favorable conditions for being cheaply mined, can be worked with profit. It is also fairly to. be con- sidered, in this connection, that the ore may increale in richness as indicated- by the Qccurrence of a better grade near the bottom of the mine than any which had been previously found. Not being an authority in metallurgy, and having only a superficial knowledge of that subject, I do not feel compétent to give any opinion on the possibility of working an ore which has yielded four and a-half pcr cent, by the Henderson Process, nor do I know how much has been lost in this process; that is, how much the real percentage of tlie ore is. As ore not averaging over one and a-half per cent, of copper is successfuUy treated in Europe, it would seem that the ore of the Hartford Mine ought to' pay a respectable profit when treated by an economical process. The facilities for opening and work- ing the "mine so as to produce a large quantity o^ ore at a low cost, are certainly very great. Very respectfully yours, Cambridge, Mas»., ) J. D. WHITNEY.

Boston, Mass Dbar Sir: •I I am in due receipt of your favor of the 16th inst., request- ing me to answer certain queries on the subject of the mining property in this neighborhood known as the Crown Mine. Query FtV«<.— The probable cost of openingand workingthe said mine through the présent shaft known as Shaft No. 5 of the Hartford Mine. Answered.— This opération would be simply a continuation of the Works at this shaft in the same style, or nearly so, as they were conducted when thfit shaft was sunk to its présent depth by the C. C. and S. C. L. of Glasgow. It would he necessary to sink this shaft to a depth of— say thirteen fathoms, and to exteiid a drift eastwardfrom the bottom 80 attained for a distance of about twenty fathoms, or so far as would be permitted by the state of ventilation in the mine; and to this end it would be necessary to arrange with the above-men- tioned Co. to be enabled to sink a winze from the eighty-flvc-fathom level at a point where this is intersected by the boundary Une be- tween the two properties; this last would be sunkto the same Jer-' el as would be attained by Shaft No. 5, and the tw>béing con- nected by the above-mentioned drift would opeirlîp a block of ore- gtonndtwelve fathoms deep by twen^/jiatliomB in length.which, if it èhould prove to be as prodîietifeas a like block in the mine of f^'^j^'.'i ^7 13 Hartford in the level above, would tum out about twelve thou- sand (12.000) tops of copper pyrites, assaymg flve per cent, for cop- per by humid assay. ^ Theworkingcostof sinkingthis-shaft, which is f ourteen feet by seven feet. containing anareaof ninety-eight square feet would average one hundred and thirty dollars per fathom lineal measQrement; The cost of sinking the winze, with an area of flfty-four feet. would be seventy-flve dollars per fathom, lineal measure- ment. And the cost of driving the drift containing a^a of forty- two feet, would be from sixty-flve to seventy dollars, lineal measuren^ent, summaW, 18 fathonu at tl30 *. »„ la " ■ 75 $1,69000 '^ 1,86000 i ^„™"' ^J^ P" "«onth, 8 months " ' **'^ S 1 engineer st tÔO per month kmantha 960 00 i'rr'.îi»«^'S'.'8mônth. iîîS 81ander«a»$a0each8month8 ÎSSS 8 ormore Uborers at 188 eacb S"** 500 00 Snperintendwce to be added W.*» 00 " \ 990 00 $9,018 00 This work would occupy, under favorable circumstances about eight months to complète; but. as an offset to this with- in two months or less after starting the drift eastwaid. the sink- ing of the shaf t would be resumed. so that almost as soon as the flrst blockof ore would be opened, the shaft would be againdeep enoughtorepeat the opération *8 above described, and theground J'i- 1 1^ *iiÉ.. f,'-'i^*i'^''-a v-îV'l- ■^..»^|l,-jM-A u- p- 9t d il >^ 18 èastof the.wings would also be opened up so soon asthis should hâve acquired Ihe re<[ui8ite depth; in fact, after opening up the flrst block of ore, the gênerai opérations ôf the mine would corne into full play, and w(|uld be increased or diminished as might be required by the then éxisting circuijistances.

I may be permi|ted;,jto remark that if this opération be con- flned to striking thfe orejiit the level of the bottom of Hartford Mfaie, no ore grouiid would be laid openfor stoping; the opéra- tion of opening ^ound for ore would bave to be commenced from the point of ilntersection, as described in the case of "8ink- Ing No. 8 Shaft.

Time requi^d for this opération about âfteen to eighteen months.* Query Thirti. — Give in each case the time necessary to open the mine, and fie amount of ore that can be delivered per month after the mina is opened. AnnoeredJ— The time has aiready been mentioned, the calcu- lations being based on the work heing performed by hand, with- out any assistance from drills worked by steam or compressed air. work^rtStarfiSt'm'^'tto**"' **"'^^ *'*'' powerdrlll», ottêt to complète this ^Màs^-'' ir' I *' ':% 14 In opening through No. 5 Shaft and winze from the eighty- flve-fathom Jevel, moderate returns would be immediately made^ as there is a small block of ore already opened at tlie angle the Shaft No. 5 makes with the eighty-flve-fathom level, which lies within the Crown Mine limits, and is ready for stoping; this would produce aitogether, about eight huudred tons of ore, (800), ^e shaft is fast leaving the dip of the ore body, and probably ■fîll soon be aitogether out of it. After sinking about six fath- oms deepcr tbah the présent bottoni, unless a change should lake place, no returns can be counted oafrom this point. The winze would go d^^wn m a strong body of ore, and ought to produce from seventy to eighty tons of good ore from each month's sinking of three and a-half or four fathoms. After the first block of ore is opened out, there would be nothing toprevent the monthly output commencing at four hun- dred tons (400), in a few months reaching one thousand (1,000), by which time the second block would begin to make returns, in fact, after two years' work, during which timc thore would be a gradually incr«asing scale of returns. I seè no reason to doubt that the mine could be put into a condition to return. if re- quired, two thousand (2,000) tons of ore per month without over- straining its capacity. Qtury Foum.—Give in each case the expense of opening the mine read^ for work, specifying, &c. An»u)er«d.—The particular opérations for opening the mine to a certain extent, and the «xpense attending them. hâve been already detailed. The cost of minmg the pre. after the mine is opened, by either of the above-mentioned methods, would not vary materi. ^ M: •X r% irt*sM^-t.'fi\^ '-» ) _ ^t'««* .\ 'i^j'C'^iXi^. %im ' '- @i, 15 ' ally, and may be set down in round numbers, for ail mining ex- penses. at three dollars per to^, ànd tbe loss in materials will throughout tlie year be about ten per cent, on the total out- ^ lay. In the case of working by contract, the contractors repay the value of nearly ail the materials they use, with which they are sùpplied by the Company at a flxed price. * Query Mfth.T-State from your past expérience, &c.. what percentàge, &c. \V, Antwered. — For the ïàst three years the Hartford Mine was worked, about sixteeu per cent, of the total output was elimi- nated to bring the ore to the percentàge required at the Ëxtract- ing Works ; thia rejected portion consisting of two-thirds ôf poor rock and the remaining one-third of ore rich in sulphur, but con- taining only from one to two per cent, of copper; this last pro- duct was sold under contract at three dollars per ton delivered at the station on the cars. '" A3 the deposit of ore âas steadily though slowly improved in quality between the flfty and eighty-flve-fathom levels in the Hartford Mine, and as it now contains little or no unproductive rock mixed with it, tbe quantity to be rejected would be rather less than above stated, te bring the ore to an average of five per cent, of copper by wet assa^,-and this, by careful manipulation, \^ ought to produce ip actual fine copper four per cent. , or, say, one \ton of fine copper to every twenty-ûve tons of ore delivered t the WorlSfl. \ The average of sulphur in the rejected ore was from thirty- eigÊt to forty per cent. , and on this basis it was sold. I do not think the better class of ore was, as a gênerai rule, fusaVed for sulphur; if U was, it never came to my knowledge. $• ^Bi' ., - ^H^ ihm'rtUt . >i / -r^/,!." \v" «.^.

Province pf Québec, Dominion of Canada, thc in « >* \ ' € / .i*' kve Invented an Improved Process for Separating Sulphur froœ I Ores, of which t^e followiiig is a spèciflcation : By thia inrention, and the mafioer of working it as herein . described, the jiydrog&n sulphide koay be produced in large quan- tlties at the smallest possible cost, and witl» the mtoimum of la- bor. &Y the intermlngllng of tbis gas wHh the>*ulphurou8 acM from the oxidatiop of the sulphides. the sulphur is effectuaUy precipiteted in a condition alniost free from impurities. I am also awi^rethat the suiphurous acld frpm the roasting of suiphurous oresjias bcen extënsively utilized by converting it into sulphuric acld; but this method is not. as a rule. economi- cally avallable, ad mines are frequently situated remote from manufacturing centers, and the transportation of the acid js ex- periKlve, both in packages and freight. Sulphur. on 4he other hand. is easily handled,/require8 no expensive packages, and can be transported. withoqt danger, to remote markets. I shall nowproce^o describe the apparatus and method of working It. ' r- I o o are kilns or pyrites burners made of any sujU^Weshape, 4^nd conslructed of refractory material. ftftare f^ to^ con- ducting sulphur-gase^. «nd in which the suiphurous gases and sulphureted hydrogen intermingle on their way to the chamber c. T»^ere the chemical reactions are completed and the sulphur predpitated according to the following chemicaLreaction ■ éOr+- 2H,8=3S+2H,0. ^^ A Jet or spray of water is made to play upon tle gases and vapors from. the top of the chamber c through a suitable pipe, to facilitât© cpndensation. The gases are further caught and « . >■ , a£- — -^.^t-.„.^.,.; .tt.vTitaft^ â{^>lSL^ I -^^ 1 j*i ^ -^-Hi. i l*-^^i^jfâ,^iji^-t"V?bi.

This water may be used over and over again until it absorbs sufflcient acid to be useful in some other process. A fire having been kindled on the grate-bârs e, fuel is pût on until the kilns are thoroughly heated. The ore is then filled in, and if it contAins above sizteen percent, of sulphur, then the beat generated by the burning of the sulphur will bç suffl- cient to. maintain the combustion, and no other fuel will be re- quired. The sulphur,^ it is bumed.' passes into the common flue b iA the shape of sulphurous acid. When the ore is in a State of combustion — say, at a red beat — the air is shut off and superheated steam is admitted through the pipe t, forming sul- phureted hydrogen, which, meeting and intêrmingling with the sulphurous acid from the adjofning kiln, causes th« wellknown chemleal reaction already described to take place, and the sul- phur' is set free. For the better and more regular working of the process, it is found préférable to supply each kiln or pyrites-bumer with air and steam alternately, so that while one is producing sulphurous acid àuother one is producing hydrogen sulpbide. At regular in- tervais the opération is rever^ed, air being shut off, and super- heated steam being then supplied to one, while iathe other the steam is shut off and air supplied. Where kilns are constructed in parallel rows, back to back, the superheated steam and air may be controUed by one valve for each row, so that each row of kilns may be producing sulphurous acid and sulphureted hydro- gen alternately, and tbus yield a steady fiow of the desired gases. / -. V i" ..•' \^a. . M . ! 1 ' . V V. isCA»-'«t45i« sii .•.'.'. / â8 When the ore is rich enough in sulphur, and the air and sti- perheated steam are properly controlled, they may be introduced simultaneously and continuously into the kiln? or pyrites-bumer, and the sulphurous acid and sulphureted hydrogen may b^ pro- duced in such manner as to cause the reaction to take place, as aiready described. In so doing, it is found préférable to admit the air at the bottom, and the superheated steam nearer or at the top. A stream of moist steam is admitted through pipe m into the flue b, so that the f ree sulphur aiready formed may be pro- tected from burning by any air which may find its way in. Some of the sulphur will be collected in the flue and cham- ber, while the remainder will be carried out by the water, and pr^ipitated in tanks pr other suitable vessels. If the ore or sulphur-yielding substances are being roasted or bumed in revolving or reverberatory fumaces, worked in pairs, the same method may be employed by altemately intro* ducing air and superheated stéam, and mixing the resuUing gases in a common flue or chamber, as aiready described. If working a single fumace, a stream of highiy-superheated steam may be continuously admitted, preferably along with heated air, and so regulated that the proper proportion of gases may be produced. An ezcess of air is to be avoided.

Howb. Direetora—VT. E. C. iûstiB, R. G. Lbckie, Robert M. Thompson; and two vacancies, which will be increased to three, by the résignation of one of tbe présent directors. Tlie property of thé Conipany consista of the Orford Nickel Mine; the Crown Copper and! Sulphur Mine; and two patents ± i\~-\i> ^»il• 07 for ptocesses for roastiiig copper ores, and the Leckie Sulphur Patent. The Company is organized under a spécial charter from the Par^ament of Québec, which exempts stockholdefs from ail liability. Its capital stock is $300.000, divided into lîi^OOO shares of thé par value of $20. $25.000 bas already been paid in for the worklng capital of the-^ickel Mine. The Company now desires to raise $125,000 additional to complète the payments for the Crown Mine, erect extraction works, and for working capital. To raise this sum, the Company oflfers iu stock at par, preferring this method to putting out a larger number of shares and selling them at a great discount. In the developement of the property, two plans hâve been considered: 'K - — First, to lease from the owners of the Hartford Mine the présent shaft; and to put up such part of the smelting works as wll be necessary to treat the ore produced. Under this plan the e^ense for the âi$t year will be : \ S8 instead of tlw profit p'f four and one-half cents per pound Bhown bythe estimâtes^ of the Messrs.

The time re- quired for this will be about eight months, and the cost $10,000 to $12,000. After the shaft is down, there will be some time - and money saved in developing the mine, and the work of pay- ing for the mine will take two and one-half instead of two years. The person who now invests in the stock will, we believe, receive within two years thlrty-three per cent. irfÇcrip dividends and ten per cent, in cash; and thereaf ter tin his stock, dividepds T^ ^..•C. ''tn mÀi r^ at the rate of thirty per cent., or on the cash invested of forty per cent. The objectof this circulafiB to provoke investigation. It does not attempt to answer ail questions that may be asked, but bycâlling at our office, 4 Pemberton Square, and talking with one of the undersigned, any further information you may désire, and every opportunity for full investigation will be given. We understand that in asking Boston investors to. take hold of a Canada Copper mine we will be at a great disadvantage on account of the ill success of Boston speculators in Canada, but we do not regard our présent oflfer as a spéculation, but as a legitimate business enterprise— an enterprise, toycsure, inwhich there is risk, but the risk is, we belieye, reduc«!d to a minimum, and the enterprise only needs good business pnanagement to in- sure success. „ / Notice the following points: ^'* ^ "■''*!?. «]*^".P*'°°^ *™ °'>* binding until the entire sum of $125,000 18 subscnbed. 8.— The subscriptions will be payable onJeasy terms, ew twentv per cent, down, and ten per cent, a month thereafter as loni as money is needed, until one huijâred per cent, is paid in, 3.— The subseribers for the new stock cân elect a maiority of thé directors; and thus control the business management oï the \ ROBERT H.
