Show THE EMMA MISE, From Mr. Attwood's report to the directors of the Emma company, published pub-lished in the London Mining World of April 20, we take the following. Tho report h dated March 6, at the mine, and "is accompanied by a chart of the working-, and after giving an account uf the roads the amount of snow i.t the miuu, etc. Mr. Attwood says: The qosutity and vulue of reserves available are not of tho great extent that it would appear, comyariug the larye amount of ore that has been taken out in tho ground marked as ! " worked out " with what I now mark as " btill in bibt," because tho pay ore is widuly disseminated through tho maa and requires very careful assorting, assort-ing, it being much mixed up with huictitonc, aud scarcely one-tenth being oi butheieut valuo to save for shipment or treatment. It is therefore a most difficult matter to givo you a very close estimate of tho quantity and value of the actual reserve;1. As near as I oan ascertain, 1 estimato that wo have about two months' work in Bight, extracting ex-tracting pay ore at the rate of thirty tons per day, containing about 50 to 55 ounces of silver to the ton, and carrying from 35 to 40 per cent. lead, say (1,450) fourteen hundred and fifty tons, all told. Explorations have been pushed very vigorously sinoo my arrival, and I have started about forty miners entirely on prospeetiug ior new deposits of miner' als, and have already found, in a crosscut cross-cut from the main hoisting shaft, about SU ft. below tho level of tho Pas-coo Pas-coo tunnel, a small leader of 8 to 10 ft. in length, and somo 6 in. in thickness, assaying over 160 oz. of silvor to tho ton, and containing 50 per cent. luad. This appears to bo a continuation of tho same streak of oro reported to have been found moro thm a month ago, under tue late management, and looks very promising. 1 am in hoposit will guide us to anothor good chamber of oro. Tho main hoisting shaft is now down to tho depth of 93 ft. below the Paseoe tunnel, tho bottom of which shaft is iu limestone, but think it is over tho vein, as tho leader abovo mentioned was found at SO ft. pitching pitch-ing under the shall. This I consider fortunate for the future working of tho mine, as it is always advisable, if possible, pos-sible, to have tho main hoisting and pumping shaft somo distance from the vein for tho safety of the shaft, enabling ena-bling the miners to extract alt tho pay i ore, without having to leave any pillars f or tho protection of tho Bame. Tho explorations aro now being carried on from six points. The first place is in the cross-cut from the engine shaft, about eighty feet below Paseoo tunnel. Tho second place being a drift, whioh will bo about ninety feet, to run in a northerly direction to connoot with the winze below the Paseoe tunnel, which I have commenced about eighty feet below tho latter. The third point will be a drift in a southerly direction from tho shaft, and at the same level as the previous ono. Tho fourth point-is point-is the sinking of tho engine shaft, which I think it advisable to continue. The fifth point is the sinking of tho winze below the Paseoe tunnel, to con nect by proposed drift with tho engine shaft. Tho sixth point is a cross-out at tho north end of tho extension of "the Pasooe tunnel, in whioh place we have a tmall streak of good oro, and are following it up. Ail those explorations explora-tions are being pushed night and day, Sundays as well. Tho surface of tho ground being bo thickly covered with snow, I find it impossible to Btart any new work from the surface, having no data or guide to aid mo in exploring. This is unfortunate, because the extent of the company's ground is so great, and only a smalt portion of it has been worked hitherto. As soon as tho Bnow permits this mattor shall have my most earnest attention. Tho geological age of the formation in whioh the vein is found is evidently that of the Silurian ; but it is a question which it will take some time and careful examination to definitely fix. Here follows an account and assays , of fillings containing ore which, Mr. Attwoods says, cannot be worked with profit to the company while the present high rates of transportation continue He then adds: The second class ores on dumps, supposed to consist of upwards of 8,000 tons, are oompletly hidden by the snow, and it will be at least two months before they oan bo thoroughly examined. exam-ined. Hoisting engine I find large enough for present purposes, but in case of siuking much deeper will have to be replaced by a larger and more powerful ono. To prevent water getting get-ting into mine when the snow melts rapidly, I am having all old shafts and workings that aro known of olosed on the surface, buk expect, in spite of all these precautions, we shall have some trouble, but apprehend no Berious delay or difficulty from it. Number of men employed as miners, oarpentcrs, engineers, wood-choppers, ore housj hands, &o., &c, foot up to nearly 150. At present, considering the largo amount of mon I have put on tho prospecting and timbering work, I cannot dispense with any of them, or increase the output much over thirty tons per day, and must therefore delay attempting to curtail the expenses in that quarter, until we have succeeded in opening out a now level. limber 1 we are well supplied with, and have ' enough to last for two months yot, when it will bcoomo necesBary to oo Dime Di-me nee hauling some, a large amount of which is alroady out. About twelve woodcutters and choppers, being etead-, etead-, ily employed all tho time, and included in the above estimate of mcncmploycd. Tho saw mill is as yet covered up. with snow, and only the top of the smoke stack visible. 1 find Mr. Hannibal Williams, who has taken tha place of his father, Mr. Silas Williams, as superintendent of the mine, a straightforward straight-forward and very useful man.and am so far well satisfied with him. Mr. John Roberts, the mine captain, is a very hard-working, and think efficient foreman, and will I think carry out my plans to the best of his ability. Both Mr. Wiiliams, Mr. Roberts and our chief clerk, Mr. Charles Smith, (who I find to bo a most oapablo and trustworthy trust-worthy man), have assisted mo to thoir utmost in showing me all tho workings ofthemino and tho general business of tho company, else should not havo been able to get this roport for you at such an early ditto. 1 On tho 2'Jth and 30th of Maroh ho writes: I havo just como out of the mine, and find no change for the better io any of the workings. I find that the i "upper" portion of the engine shaft has moved since my last report of the 25th instant (having marked the timbers, tim-bers, Sec); so, considering the safety of the mine, havo made arrangements to have tho Bhaft re-timbered at onco, and think it will take at least ten days. This will, of oourso, prevent hoisting ore, but have arranged to have the ore still taken out and assorted underground; under-ground; and as wo have a large Bur-p'us Bur-p'us in tho ore house it will not interfere inter-fere with us financially. 1 have had to offer 12 per ton from tho 1st April for hauling our ores from the mine to Sandy station, until further notice, as I find it impossible to get but a small quantity of oro down at tho present price of $1U per ton. Inolosed you will please find oro account for tho last week. You will notice that tho amount of ore extracted is only 155 tons. The small output is occasioned by the great difficulty wo find in assorting tho ores, and also having to put such a large number of men on oxplorutiuns and rt-tiuibeiing rt-tiuibeiing ihu old workings to aiuke them a? secure as ;-orib!o. The n-'W explorations show uh yet no cirango for tho better, but cannot expeut much improvement lor muio weekj tu come. After having cruf'ully examined the mine, day uft.ir d iy, 1 tiati nothing to alter the opinion 1 i-rprc-cd in my report to you of the 20, h iuM., at.! am u.-ing ovcry effort to rush forward lhe now work, and also to try and find Borne new place in which I think men could bo put at work with some chance of finding new deposits of ore. On the 31st he adds: Tho bottom of the winzo below the Paseoe tunnel is improving, and assays show over thirty dollars per ton io silver; but, straoxe to say, only a trace of lead. Tho other explorations show no change. 1 have just completed somo analyses on a large scale to prove the quality of the second cla.-s hlliuys in reward to the amount of "tree milling silver" in the same. The results are as follows : Assay of filling fro in above drift No. 7, contained lead, j percent.; silver per tou: oz. 37 '00 4869 dols. Contained silver, probably proba-bly as sulphide, 00 10 per cent,; deride, de-ride, 15"21 per cent.; sulphate, 24 03 per cent.; total 100 00 per cent., showing show-ing that only 39 84 per cent, of the silver is m a "free milling state" in the second elastt fillings. And on April 1st he again writes : Tho only change I have to report re-port to-day iu the mine is an improvement im-provement in the lower winzi, below the Paseoe tunnel, an assay taken from tho average of the bottom of whioh gave the following results: Contained lead, 71 per cent.; silver per too, 32 oz., $75.40. An analysis made from the same to prove tho amount of freo milling silver shows that 31.20 per cent, of the silver is in a free state. The percentage of load, as you will observe, is too small at present to pay for smelting, smelt-ing, and I am having ono ton of the above class of ore and also of fi lings sent down this evouing to Salt Lake, to enable mo to treat them myself by amalgamation, to prove their immediate imme-diate value to tie company. To day I have been paying off all the miners and workmen, it being the first of tho month, and will Bond you the accounts in full as early as possible. The weather horo is fine, and the ore teams are coming in faster for the "sacked ore," and hope to got down much more this week than wo did last. Mr. Atwood doses his report with a caution against crediting any rumors concerning tho Emma, as he has been weeding out tho miners, and for tho present has determined not to allow any one to enter tho mine; so that other reports than his own, being from outside and uninformed parties, cannot bo deemed reliable |
