194 MINING AND SCIENTIFIC PRESS. {March 28, 1874. jGORRESPONDENCE. Knox._& Osborne. ys.—Ph enix Mining “Company. 9 ~ » a = 5 = Eprrozs Psess:—l notice a paragraph in yonr laet issne (March 21) referring to a snit recently decided in Napa,entitled ““Knox & Oshorne vs, Pheeniz Mining Company,” in which ths published otatement ‘(not original with yon) does not in any_particnlsr repreeent the facts. The suit was commenced for an amonnt lees. then “$8,000,” snd ~afterwarda, -hy.#greé-. ment, submitted to arbitration. The resnlt was an award to plaintiffs of $5,000. It was attempted to he proved by the P. M. Co., that the furnace (the psy for. building which was in controverey) was badly constructed, and that the company loet large amounts ‘of quicksilver; and’ hence resieted payment for halatieé dne. In trying the esse, the following evidence-was pnt in,-showing the quantity of: the, ore, and results of the furnace vorking. . . __ An sssay was off: réd by plaintiffs, made by . ‘Riotte & Luckhardt, in May, froma sample . takeu from ahout 60 car loads, about May 4th to 7th;.of what is called cosrse ore; also from . ‘a portion of about 20 sdohes, taken ‘from dif-. ferent parte of the pile by myself, and as fairly .

The assay in May ehowe whst the ore contained. The reault shows that in Jannary and February, while the new condenser of! sixteen chamhere was ,heing costed, the yield wae 37-100 of orié per cent. assay, 46-100, or a logs .of 9-100 of one per cent. In April, it showal 412-1,000 of one per cent., or lessthan 5-100loas. from assay. ._ In May the result is 953-1,000 of! one per cent., assay one per cent.—losslessthian. 5-100 of one per cent. Now, Mr. Editor, if] this result is hadin a badly constructed fur-. nace, whst may those ‘expect, who have good structures of our patent? For a hadly con . structed turnsee, (ss this one is claimed to be), . Jam satisfied with the result, till “something! Dettar is found. It is trne that there will be a. little moré waste, and loss in drying out a now . furnace and getting itup to the standard! working heat, which will.occupy from forty to . fifty days, than ever afterward, but ,the 9-100 loss in Jsnuary and February, over and ahove . 5-100 of one per cent., was in costing the con“densers. “What one other furnace has done, ia shown by a communication, in your valuable sheet, of October 4th, 1873, from Hubert Bankert,Mining Engineer, and Superintendent of the Nspa Quicksilver Mining company. He ssys: ‘In our works, out of sixteen hnndred tons, worked in this way,’ (through their furnace), ‘‘only an average of eight. and one-half pounds per ton was ‘obtained, where the ore treated contsined hy,. repeated . esssys. from twenty to eighty pounds per ton.’’ Now, i will take the twenty pounds per ton, or one per cént. as the: fair asssy of the ore treated, the yield was eight and one-halt’ ponnds, or 42-100 of one per cent., while the loss from asssy is 58-100 of one per cent., or nearly three-fifths of the whole,’ I’ might refer any who are cnrious to know what’ other processes’ lose in the réduction of.cinnabar, to an article on “quioksilver extraction,” in your paper, August 23d, 1873, without copying it here. Wishiug all partiss ereoting reduction works, may have the good luck to get a furnace that: will make retnrng only 5-100 of éne per cent., short of the assay, and they, will prosper. R. 'T.

Star, u 6 . writer, with many others, thinkeit the brightest day the district has ever ceen, -'The sping will open with two smeltars, anda ten-stamp millin successful operation. True, money just now 1s scarce, hut we sre not alone in this difficulty. Onur neighbors are ae bsd off ae ourselves, and thronghout the country there sppeare to bea lack: of enrrency. The financial panic has affected the mining portions of thie country as mn¢h perhsps as any other.. Thisis owing to the fact that a large-amount of ready money is. /slways necessary to .carry.on mining, success: fully, and in new dietricta it has to come from abroad. Suchie thé case in Stsr. It is only within the last few months that money could he realized from the esle of ores.. A coneiderahle amount hae heen sold to companies opera~ ting here on a credit, which hss not only introduced all the inconveniences aricing from doing. business on “tick,” but paymente having been, delayedin somé ¢sses, has given rise to,distruet, . and furnished employment that chronic . mémber of Society, the grumhler.“Itis to be hoped that ,this very objectionable method of doing business is, dxawing to an end. The intereet of coripanice, aswell as individuals, ie promoted hy making immediate payment for whatever they purchase. ‘“ Every article can he purchased from five to ten per cent. cheaper, to gssy nothing of the life.and ,activity which the psy-down principle infusee, _. =o ; ~.. +, Labor and Character of Ore. More work has heen done on the mines during the winter, now drawing to a close, than st. any previous period‘of timie, and with ‘a: few . exéeptious, the developments are encouraging. One thing is beiug demonstrated daily,.ifindeed it is not already an eetablished fact, that Stsr'is a base metsl region, requiring furnaces to work its oree.’ Lead predominated’ every. ‘where, and ite valne is quite'equal to that of eilver. To throw away the lead, would, in 4 majority: of cases, prove a ‘prodigal waete, and leave a elight msrgin for profite ahove costs of mining and milling. This view of the case, no experienced miner will gainsay. There are eonsiderahle milling ores in the district, thongh as fsr ae yet ascertsined, they are of rather low grade. How the Mill may Succeed. The fscilitiea for reducing by the mill prooess are so good, thst with careful management, ench ores can be worked with a profit. And I am.confident that the mill at this place, though it hae not met with the succese that wss anticipated, will yet pay a handsome dividend to its owners. Let-the company pay down for their ores, and meet the running expenses of the mill as theymature, and they. their ores ten percent. chesper for cssh in hand, thsn on even 8 month’s credit. Laborers will work ten per cent. cheaper when they get their pay as they go along. Ths company heing a weslthy one, thereis nothing to hinder them from adopting the pay-down system, and it will certainly put wind in their ssils if it does not prove the meane of saving the ship. To Attach a Smsiter. I nnderstand thst it is the purpose of the company to erect a smelter in connection with their mill. This is a wise policy, as their ample steam power will furnish any required hiast, and the site is convenient to a large number of mines that produce lead ores. So far, the mill has been kept in constant’ operation, snd the prospect is thst there are sufficient ores in reach to. keep it pounding away through the yesr °74, at least.’ ; 5 Thus, with the bow doubly strung, onr Csnadian friends ought to make money, and find their Utsh property a psying investment. Such, Iam warranted in saying, is the general: hope of the, miners. at, Star; for the company is 4 most honorahle one, and withal, the’ pioneer of qusrtz ‘milling. in Sonthern Utah. “9 cm ea o4 More Money for the Enterprise. Dr. McHattie, one of the principal owners, heretofore the comipany’s agent, is expected within thé next week from Canad, ‘He comes with money; aud lively ‘dperations -aré anticipated. The'doctor hae many friends in Star who are looking ‘forward to his retnrn with considerablepleasure. © al a «. ,. The Furnaces. : pa JThe furnace at. Shaunty. sprigs has been running the greater portion of the time during . the winter, turning out several hundred tons of bullion, the precise amonnt I do not know. The ores used have been from.a great) numher . of mincs, so that the value and oharacter of the . mineral of the district has heen pretty extensively tested. These ores readily flux by mixing, though it has been found necessary to roast some of them to destroy the sulphur and . arsenic whioh existed in sufficient quantity to choke the furnacs. I am informed ‘that. the bullion carries 90 ounces.of silver to the ton. This is worth $1.25 per ounce in New York, The lead is worth 54.5 cts. per tb.) which brings the value of the bullion up to $228: per ton in New York, in gold. 'The-outlay I can: not definitely stats. The charcoal costs, at the furnace, 25 cts. per hushel.: The hauling of the ore from the mines is done hy'the Mormon citizens ata very-low: figure. ‘The freight on the hullion to the terminus: of the ‘Utah ed up on ore from the same mine, # 4 hs Southern has been about. $23 per ton. ae prey ope SN are “doctors ‘are somewhat. disagreed, hut” the} can not fsil to reap a profit. ~Miners will /eell] -. . cisco,

Vy j This furnsce, which ia eituated, at’ Wah-wah Springs, has been running the moet ofths time for ahont six weeks, andhas turned but 200 tons of bullion, all of which has been shippe tothe railroad-at a cost of $25 per ton. ‘This4 bullion is the product, exclusively of ore, from the Mountsin Queen mine, situated-in Pruess. District., The value of the bullion in, silver is} not known kere, but I; think thatit is. not: greater than that produced hy the Shaunty: . gmelter, if indeed it he equal to it. What has Been Accomplished. In relation to ths works at Wah-wahj it is hut just_to, the company to state, that they -have heen constructed, and so fsr, operated fander the most nnfavorahle circumstances. Thé first hlow was struck in the middle of the winter, (the moet severe for a dozen paet), since which time has heen erected and opersted the most snccessful furnace ever huilt in Utah. Its espacity is four tons of bullion in five hours, or fourteen tons in24 houre. The chsracter of the ore hse had muck to do, no doubt, with-the qusntity of bullion_produced. The former, from the Mountsin Queen, mine, and‘ charcoal from pinyon pine were thrown.into the furnace together, and lo ! the bulliou by the hundred tone.: The company hss now commenced to hny oves from the San Franciecodiatrict, which will, no donbt, increase the value of their bnilion, se this. dietrict' produces eome very fine mineral. pe Rdg mn . The Mountain Queen Mine. ° ' This mine hss generally been considered one of the big things of the country, though it has not-yet been thoroughly prospected, a depth of seventy feet only hsving been reached. The yield has been immense, and the ore is said to etill ehow in great quantity. It is mostly a osrbonate and decomposed-liks soil. A Field for Operations. There is abundant room for other furnaces in Besver county. Beaver lake, San Francisco and Lincoln districts need one or more furnaces eich. I am convinced that smelting can he made to pay with present fscilitiee, hy shippiug the hullion, se Shumer & Co. sre doing, direct to New York. A hetter way, where the comany ie ahle to meet rnnniug expenses, would Be to pile up the bullion st the furnaces and await the approach of the railroad, which can not longbe delayed. It is destined 10 make another etride at leaet, the coming summer. The cost of freight from Star to Provo, the railroad terminns, would, were railway trsnsportation complete, pay the tsriff to Omaha. The amonnt whioh would thus be saved, heing $14 to the ton, would of itself sfford a handsome profit. But, as there is already a gain, it would amount to more, perhaps $20 per ton. This, se any one can eee, would he a paying husiness. Minos. ~ Idaho Mining Notes. ¢ The Owyhee Avalanche contains the following mining notes: Superintendent Boyle is rapidly getting the Silver Cord in “shape for extensive working. The main shaft is now down 74 feet below the second level. The first level is in 75 feet north, and the second in 100 feet north. The ledge in some places shows a width of four feet, and is very rich in gold. Mr. Boyle says that by the first of June he can give 75 men employment in taking out ore. The Silver Cord isa very.easy mine to work; and, judging from present appesrances, will turn out plenty of bullion uext summer. / They cleaned up the last run of Belle Peck 3] ore this week, and it panned out handsomely. The crushing of 28% tons at Trssk’s arrastra yielded $5,948.44, or at the'rate of $206.55 per ton. The bullion assayed about $11.50 in gold per ounce. . The Belle Peck’ will make things lively in Webfoot Gulch next summer, The South Chariot Company have purchased from.H.S.
