Dark iron-gray quartz, with fine sulphurets in irregular layers and spots. A specimen of the general character of the ore. 176—From the same mine, is exceedingly rich with fine gold, so thickly interspersed that the precious metal predominates in a considerahle portion of this sample of ore. It is from a new development in the mine, which was noted more particularly in our last issue. . 177.—From the Nevada Quartz Mining Company, one mile below Nevada City, on Deer oreek. This sample is composed almost entirely of heavy sulphurets, whitish, gray and yellow, with white quartz and gar Jena and prohahly antimony. ‘These sulphurets are said to sometimes assay $400 per ton, and work, on an average, hy chlorine process, $150. Wm. M. Ratcliffe is Superintendent of the mine, which was loeated in 1851, and is now worked with a 12stamp mill. Four of the stamps weigh 1,000 pounds each. , 178.—From the Wyoming ledge, located just helow the Nevada mill, mentioned ahove, Mostly sulphurets, soft, and very much decomposed. 179.—From the Empire mine, Ophir Hill, Grass Valley.

Deep yellow color, yielding from $300 to $400 per ton hy chlorine process, Further notice of this mine will be fonnd in a future issue. Important DevELoPMENTS Iv Dr Norte Counry.—The superinteudent of the Hanscom Copper Mining Co. has recently discovered that the croppings of that mine consist of decomposed auriferous mundic, quite rich in gold. Some two tons of this mineral, which was receutly sent to this city, has heen worked in small lots hy different parties, with very satisfactory results—although the working processes do not come near up to theassay. In opening the mine, some four years since, the miners went down in this mass of decomposed mundic some ten feet, when they struck copper ore of such richness as to warrant the running of two tunnels to strike the yein—one at 160 and the other 400 feet in depth. The upper tunnel has reached the vein, and developed a three or four-foot copper vein, carrying oneach sideseveral feet of mundic, evidently identical with that from which the decomposed gold bearing mineral on the surfacs mnst have heen derived. This development is a very important one, andis almost precisely identical with the deposits known as the Harpending mine, near Lincoln, and that at Quail Hill, near Telegraph City and Copperopolis. Measures are in progress to secure still further developments with the view of eventually putting up machinery for working this newly found auriferousdeposit. This locality isin Del Norte county, Low Divide District, ahout sixteen miles from Crescent City. There are several other coppsr mines in this district, which will prohahly be found to possess a similar deposit, as soon as attsntion is called thereto hy this publication.

New Hoistine Apparatus For Mines.— An improvement has recently heen hrought out in England in the raising of cars, ores and dehris from mines, which consists in the arrangement of a hucket or car elevator, in connection with guide wheels and rods operated hy means of a hoisting rope or chain, working on a drum or windlass hy horse or steam power, in the ordinary way for raising or lowering the hucket or car, so that it shall he steadily supported and discharged hy the deflection of the guide wheels from their normal line of travel on to inclined ways, the axis of the guide wheels forming a traverse line of support, upon which the hucket or car is canted or tipped over for the discharge of its load, as it is raised by a lever hall attached to the lower end. By this arrangement no additional oower is required to upset and empty the hucket or car containing ore or coal into the shoot at the mouth of the mine, as in ordinary methods of attachment, in which the hucket is suspended at & point between its upper and its lower end, and tipped over by some ohstacle which arrests its motion—as, for instance, upsetting it hy grasping and upholding the rim with the hands. An ohstacle placed in the way of the hucket to tip it over increases the resistance at that point, suddenly producing a shock and strain on the power, which should he avoided, as the power in that case must necessarily he sufficient to overcome the greatest resistance in addition to that employed in the operation of hoisting. Thisarrangement permits the hucket or car to be loaded with coal or ore, or discharged at various poiuts in the shaft of a mine, so as to be used for a numher of drifts or levels at different depths, and also to discharge water into an adit or shoot for carrying it off. ANovet Vusseu.—Mr. Wehb, the wellknown New York shiphuilder, is now constructing for the inventors, Messrs. Blonquest & Crook, a queer kind of vessel-wagon which it is claimed will do as well on the land as in the water. It consists of 2 horizontal frame or raft resting upon the axles of three water-tight cylinders, drnm-shaped, one forward and two aft; the latter heing each half the size of the former, set parallel to each other, with a space between them of two and a half feet. Within this space is a parallel wheel attached to one of the drums, but of smaller diameter. Steam is to he used. The inventors say that in the addition to the advautage of heing able to roll overa sand bar if one should ‘‘snag” in its progress, 2 much higher rate of steam can be obtained than with 2 vessel of ordinary construction, in consequence of the ahsence of friction, and the reduction of resistance, ie Provipence Ming.—Mr. Dingley, diseoyerer and superintendent of this mine, located a mile helow Nevada City, on Deer Creek, exhihited to us a heavy hody of sulphnret ore some seven or eight feet wide, on a recent visit to the claims. Workmen were engaged near the surface on the ledge, stoping out ore for the mill, located at the foot of the hill, several hundred feet helow, More than $35,000 has heen extracted from this chimney. A portion of the chimney averaged from $15 to $20 per ton. The claims have heen worked with more or less suecess for over eight years. The lower tunnel extends heyond the ahove mentioned chimney 300 feet, developing another chimney of paying ore. No work has heen done helow the level for want of hoisting machinery. There are 3,100 feet in the claims. The mill has a powerful engine, twelve stamps, five Knox and one William’s pan, blanket sluices, and an Attwood amalgamator. Hight of the stamps weigh 600 pounds, two others 900 pounds. No. 2.screens are used in the hattery. Four of Bradford’s ore separators will be superseded hy rockers for concentrating. Some yich sulphurets have heeu taken from the rock, which is usually hard to treat. <A quantity of ore is accumulating, and the mill will soou be running. Wehelieve the mine to he a valnahle one, only needing a proper outlay of capital to render it very profitahle. The company is incorporated in San Francisco, J. M. Buffington, Secretary. Mr. Diugley is alarge shareholder and a diligent. manager. Weekly Stock Circular. Of Associated Brokers of tho S. F. Stock and Exchaage Board. San Francisco, Sarganay Maan) August 10, 1867. Money Market. We haveno materia] chango to note in the money marKet since our last issue. Capital continues ahundant at easy rates—say 1@13{ @ cent. in hank, and 1 $ cent. per month as the outside rate in loan associations; less favorable names are negotiable at 14,@1% 8 cent. per month. The liberal dividends already announced for Augnst, and others that will yet he made, will add considerahly to the present available funds. The requirements for business purposes are far from pressing, and the demand is in the main rogulated hy immediate local wants. The Treasure received from the interior, through the principal public channels, from the 1st to the 7th inst., inclusive, amounted to $1,129,856, showing a very fair increase over the returns for a like period at the close of July. The receipts eoastwise have been $140,000 from Portland, Oregon, $20,700 from Victoria, and $8,300 from Crescent City. Quotations for steamer purposes are a8 follows: Gold Bars—in rather good supply—rule at 890@900; Silver Bars, from ordinary grades at par to 4 @ cent. discount and 4; @ cent. premium. Currency Bilis on the Atlantie cities are offered at 35 @ cent. premium; and Sight Drafts, payahle in coin, ean be had at 2% @ cent. premium. Telegraphic Transfers are made at 23; ‘A cent. premium. Mexican dollars are quotable at 34@3% B eent. premium, nominal. Sterling Exchange on London, hankers’ 60 day hills, 48d; Commercial do. 49@493gd. Exchango on Paris, 6 franes for 30 days’ hills City Stocks. The stock market, other than mining shares, remains inactive, and tho sales during the period under review have heen very limited. At the close we note sales of San Francisco Gas Company at $64 50@64; and Spring Valley; Water at $66 75 per sharo. North Beach and Mission BR. R. is quotable at $49 60@50 50. This company will in all probability pass its usual monthly dividend. They recently lost the suit pending in the Kearny street widening ease amounting to $20,000 in eurreney, and the additional track required in this street will involve an expenditure of ahout $10,000, hesides they are at present carrying an indehtedmess of ahout $10,000. We hear mention made of the extension of the Front Street, Mission and Ocean Railroad beyond its present terminus. How soon or to what point we have not learned. Wo quote it at $15 hid $20 asked. Mining Share Market. ‘The mining share market, since our last reference, has heen exceedingly depressed, most shares falling much helow our previous qi ti Want of fid seemed to pervade all dealers, and during the past week the investments have been mostly made for speeulative purposes, though even on this aceount the demands have not been very pressing. Tear had taken possession of timid holders, and the purchases made one day were sacrificed in many instances at an enormous discount the succeeding day. However, on the contrary, pretty extensive option p: have been effected in several active stocks with a view of replacing, to some extent, at least, tho heavy losses recently sustained under the rapid decline; and we think with some prospects of success. The demand at the close to obtain shares at a low figure, hss stimulated the market considerahly, and a few stocks havo stiffened somewhat—independent of all other mnder this infl If the least sustaining power is given to this movement a rally may ho anticipated throughout tho entire list, A number of companies have already announced thoir usual monthly dividends, and so far as we have heen able to ascertain, the hullion product of the usually ih d in our statements, which is a true index of the condition of the Comstock Lode, hae heen $1,475,000 in July, against $1,438,387 in the month of June. SavaGE—Opened at $4,450 per foot, then sold at $226 per share, under the subdivision of the stock, equal to $4,500 per foot, receded to $195, ex-dividend, and closed at $194. During the week ending August 3d, 2,144 tons of ore were extracted, showing an approximate value of $78,157, or $36 45 per ton. Thie ore is classified as follows: First, 13 tons; seeond, 255 tons; and third, 1,876 tons. The north mine, on the seventh level, continuce to yield the largest quantity, having produced 1,170 tons during the week under reviow. Tho mine is reported to look as well as formerly. During the month of July the bullion returns, in round numbers, aggregated $375,000, against $370,500 in the month of June, <A dividend of $12 60 per share, equal to $250 per foot, wae payablo on and after the 8th inst. At the close we learn that ore on the seventh or sceond stationisin some places sixty feet wide. In the middle drfit, on the third station, penetrated ore fourteen feet thick, which is said to be of a fair third rate quality. Hate & Norcross—Continues out of the market; offered at $3,000 per foot. A winze has been started on “the 780 foot level, which, at a depth of eighteen feot, carries the same quality of ore as found ahove; otherwise, no change to note. Work on the new shaft has heen suspended for a few days, owing to the strong flow of water. The G5 per cent. assay value of 3,278 tons of ore sent to custom milis during the month of July is $193,906 17, equal to $40 35 per ton, against a product of $117,728 23 in the previous month from 3,302 tons of ore; however, in July the mills did not fully work up to the 65 per cent. exaction, which, in order to show the exaet yield, will reduce tho ahove figures a trifle. The usual inonthly dividend will he disbursed on tho 15th Neral inst. Cnown Pornr--Was in lese favor early in tho weck at a decline, gradually receding from $1,035 to $900, rallying to $1,100, and closing at $1,290. The hullion roturns in July show a yield of shout $117,000, against $77,550 in June. Sinco the 1st inst. the 65 per cent. assay value of , 400 tons of ore show a yield in bullion of $14;681, the agsays per ton running from $46 22 the highest, to $27 . the lowest. A telegram of the 9th states ” that they are down twelye feet on the 600-foot level; ore nine feet wide, and of fine quality.” YELLOw JackeT—Has finetmated iderably, at $1,060, advancing to $1,110, dropping to $985, then selling at $1,075, and closing at $1,085. It is said that a fair hody of ore eighteen feet wide has hcen developed above tho 700-foot level, 180 feet to the north, with good indieations as to the prohable extent. GouLp & Curry—Has been in less favor at a considera. hie recession, declining from $665 to $530, and elosing on Thursday at $540. The mill started on the 2d inst., and is said to work well. The supply of ore at the mine and mill amounts to shout 6,000 tons, and during the past two weeks one hundred tons have been extracted daily from the old chambers. There is no very material ehange to note in the mining operations at a greater depth, CHOLLAR-Porost—Has heen somewhat inquired for at declining rates, receding from $415 to $330, improving to $366, and closing at $364. The developments at the Blue Wing station, it is reported, show a large body of ore stated to he 75 feet high and 20 feet wide. No change in the drift on the 711-foot level. Difficulties are encoun tered in sinking the shaft hy the appearance of clay, which is said to extend over the west half, and is pitehing to the east at an angle of ahout 65 degrees. Tha bullion returns in July amonnted to $311,681 17, heing the product of 11,221 tons of ore; in June the receipts aggregated $345,000. They make a net profit of $90,000. It is expeeted that the usual monthly dividend will he dishursed this month. Kenrouce—Participated in the general decline, opening at $350@365, falling to $305, then selling at $285 exdividend, and closing at $330. We have heen unahle to ohtain any information in regard to the condition of the mine. The hullion yield in July amounted to $125,767 31; in June to $180,255 51. A dividend of $40 per share is payable since the 8th inst, Inrentar—Receded from $203 to $180, rallied to $185, aud closed yesterday at $178. No change in the inine or mills. The construction of new works at the Imperial. Empire shaftis progressing rapidly, and it is expected that the engine will soon he in position. The stamped value of the bullion received in July amounted to $99,627 64; in June $107,000. OvermaN—Was one of the principal features of ths week in stock circles, selling quite extensively at variahls rates, opening at $90, drupping to $47 50, gradually improving to $106, and closing at $75. The latest information ig to the offect that ore is making its appearance in the south drift from the fourth floor of the 300-foot level. The ore extracted to July 31st amounts to 2,970 tons, of which 591 tons were rednced at the Sacramonto Mill, showing a yield of $22,370 04, or $37 83 per ton; 380 tons at the Winter's Mill, yielding $11,971 11, or $31 60 per ton, and 834 tons at tho Excelsior Mill, producing $29,430, or $35 28 per ton. The aggregate yield has heen $63,771, andthe milling expenses amounted to $26,220. On the 8th inst. au additional har, valued at $2,000, was received. Orxir—Has been less active, receding from $116 to $95, and closing yesterday at $100, Preparations to commence sinking the new shaft have not yet heen fully completed. Work is continued on the lower lovel, and it is said with some hope of suecess. Conrimence—Sold within a range of $60@65. It is said that the oro in the third level, from which the greatest supply has heretofore heen ohtained, is nearly erhausted in the northern part, hut the southern portion will continuo to yield considerable yet. A drift from tho second level, on the east ledge, in running south 60 feet from the shaft, is reported to look very well. During the month of July the bullion receipts amounted to $16,527 62 against $14,000 in June. The average yiold per ton was $19 05. Gop Haw Quartz M. & M. Co.—Sold at a marked des cline, closing at $131. Itis said that fine orois at present sight. The hullion returns in July aggregated $10,. 250 67; intho previoue month, $12,500, The expenses aro stated at $6,830, leaving a halanee of $3,420. A divie dend of $15 per sharo wili he disbursed on the 15th inst. AupHa—aA few feet sold at $400.BeLcHER advanced from $175 to $235. .Srzmna NEvapa advanced from $26 to $45, then soldat $35, and closed at $40. This improvement is hased on the prospects of reaching the ledgo after the wator is pumped from the mine, mz chinery for this purpose heing nearly ready. Emupme—Sold uniformly at $180. The receipts of hullon in July amounted to ahout $25,000; in June, $21,600, .-SEGREGATED BeLcHen sold at $4 50@8. Work has heen suspended in this mine. They are waiting to take up tho drift from the Overman mine, so soon as that company reaches their line, and mean to develop their property through that level at greatly reduced expensc, An assessment of $1 per share was levied on this stock on the 6th inst. The aggregate sales of Stocks, Legal Tender Notes, etc., since Saturday last, amountod to $1,229,880.
