GOLD MINING, AND THE GOLD DIS.

COVKiilSd MADE SIN'CK ISSI. BY J. ARTHUR I'HILLtI'3, K-50,. (Read at t!is Swsiotv «f Arts oa WYlnssday, May 14.) (Continued J'roni ou,r last.) It ha {•.enerally admitted m;t that v.iin3 of auriferous quartz hive liuta or no relation, with regard to the exp a ru of vrarkia-.; them, v.itli the more readily worked alluvia! <3i'-j>oMtrt in their vicinity. In the one Pas- the ro«'; liih to b; broken, crushed, find wi-he I, at a considerable expenditure of time and money, wldLtin thoiillier, Nature has for centuries iw en carrying o'l tln'.^j operuti m-, an i *i pri;pa-in_c the goUi as to admit of it.4 extraction hy very simple im ans. It consequently fullows that tile period at which quartz veins can be advantageously worked ia any given loenUty will not entirely depend on their yield, but will also he more or le-a influenced l.y the abundance au.l richness ot the alluvial di^in^rs in their vi<;hiity, and tiiu gtiiH.-ra! pritx* uf labur an I :u tvri;ti* in the district. The supply and consequent price of labor] must a!«> Ik,- matcria'ly influenced by the distance at | which* the »o! -i-producing countries nmy be situated j from the tfio.it. centres of civilisation. From their j remote!!:.-:^ a'i-1 their consequent diinju'ty of access j Australia a>ul C;tlif»rnia for a considerable period offered striking"1 examples of tli> demand for iaiior , exee-dintr the supply, but the constantly increa.MUij facilities aif.-rdsd for travelling, and in some instances their nearer proximity to Europe, will profriahly prevent this oe-uiriii;* to the s-urie extent in the more, recently di-cove-red pjld-iields. There is, tht-re-fore, every reason to believe that the amount of gv>H annually derived frun th-j n-orkmjj of ir>! 1 quirfz will gj on <,'r:idim!ly and rapidly increasing ; and that, by the introlut'tion of efiicjent and powerful machinery,'ores of a very !~nv produce wi:l lutitnafly be treatcl with advantage. 'f he*; ofi.-*rvßtion.s particularly apply to the province of Nova Sc.tti i, whose portion senders it impossible that labor hhould ever attilr.i»n excessive v.;iu.*, whilst, if a lar.;e t-upply <i aurifrroas (|!)arfz can W obtained from U,e uilnes of Xorth j Wall*, si is evident that a very .small yr.-'d of cold, if contiuiK'US iii)j;'.it Ixj rendert-d'ifi iiuii'-r. jtiv>.

The operations of stpM-atinjr oxi.Je of tin from iLs imtiiv, and #ii.

It is, then:fore evident tii-it when lane qnantiiies of auriferous quartz can Iw olitainrd, in a country wjiere tij« price of hbor is not hi«h, it i.s not neccs-ary that it should contain a large amount of tha precious metal in order to reader it« treatment by the aid of wellconstructed maehiuery rerauni-rative. As an instance of the very small yield which, under peculiar circumstances, may be rendered available, I would adduce the fact that at Schernniiz, in 11 unitary, ia the year 184*2, the total quantity of ores stampe-l wis above 40,0;)0 tons, and the average of the us'-ful metals extracted from 50 tons was—jrold. 3 ozs., --ilver derived from the separating"; process, 3] lb«.; lf:ul similarly olitaioed, Si cwts. ; the ratio of the pold to the otiier materials being here as one tn half a million. It is also important to state, that in this instance the ores had to be broken from solid lodes, at depths extending to 200 fathoms from the surface.

Toe St Davri's loJc-w-.s not, Ii: tlioiurat, vertical, as Mr. Fhiiiipi bad <k- orib -1 it, but (iipped north, about 18 in. per f:a.

In 13"45, Mr. Ci<>odma!i four.d 2u-> tons of auriferous q- artz us the neighbourhood, which was dressed as eopp.r ore, copper b-injr also contained in it, and aid rot! smi-ltt.-rs. who found out its richness for goli, an I exprcs-ed tha desire to have more of it, but for some reason the supply was not continued. Wheu Berdan's pans were iir.it tried dowa there th*y did njl .succeed wli^n ore rich with visible gold was ]il u:-A in them, and the goii wa* nr>t extracted. Within trie Lt«t two ye :rs, however, better results hvl bs*:» jb'a )i>*.l, owing to a different system of working h-Siwi pursue!. Formerly they treated frim 0 to l'J tons of .-tun per day, n >'.y only 20 or u'J cats. At the present time, again, only one bail was u=ed iu>ie.id <>: two. Jt hii iio;v, lie thought, been proved beyond <{U>'S-,iun, not only that the deports iv Mtrion'tlishire w.-re the richest known in this country, bat also in any other. The stone which lie hai placed on the table would give, he would undertake to siy, a yield at the rat* of 3,000 oz*. per ton, and it was by no means an i>oLted specimen at the Int^matiunid Exhibition tiicre were large ro-ks of ore equally rich. He thought he had now so far progressed that the gold demits of Wales could be worked with great profit. To pass for a few moment* to ihe Civm'tesiau. lv 1351, the mine was worke-l, but liad since been suspended. The <iepa«ib*, however, wer-i precisely tl;e .-same as at Dctlfrwyuoy. and the yieM w.»- never less than 15 dwt*. of gjfd per ton at CVjahesiau— the eoucentratal or.; being woith 3JO oz% per ton. Th'-ra. is no di faculty whatever inmakia^tlie Cvvmhosim as good, as the Clogau. At Doifrwyuo^, 11 ozs. of .croid has been waahed out by Inn!, at a cost o i L 3, and he thought the whole distri-t would be found of equal riehue.ss. It was au important fact that at the Port Piiiliin.Cjuipany.'s works ore containing hut 10 dwts. 8 grs. of gold per ton could be probably treated, and that the total cost incurred was but Ss. 4d. per ton of ore trcutai. From this he considered they mi,'ht iairiy ilraw a conclusion with regard to Wales" If in Australia, where lal.-or. iitel, and mac'u^ety were all more cnatly than in Wa os, ore coutaiiiiog but 10 dwts. 8 gr.i. per ton could he treated for Bs. 4d. }>er ton, and leave a large profit, he thought that there must be a fair criance tor the C\vnihc«an, where lhe ore would give 15 dwt«. per ton, and where there were great facilities for obtiiuin;^ labor, fuel, and materiais. Profc«or Tcunant said that he had placed the niijlcl of the '• Welcome" nu-iget oa the table, nnd he hail wiili him the first irj^nd brought from Nev Soaih Wales to England, iv i;si—ilie"uuz^ct wiiieh created s;icli a iseasati>ii in the iir-t lnWr-naiional Kxhibiiioi:, and k-,1 some timid folks to ftstr that the value of s jvereigiis would soon be v.'->rth not more than hak'-si-crown i;:ich. lie nse.l not say that tnc>e foilslnJ hji been realised, 3n\>nji_'us contltniiii:r to be quite a- yaiiiiblc a.s ever ; though from th* (■OAu.iieace^u-iit of yoi.i working in Ausiraut, we iiave received, up to lhe present time, no le>.4 than LIOO,0{ J;»,OOj worth of gold, or in weight over l.OOi) tons. He would ask them to examine a specimen of the ;p>l 1-bjaring rock of Kuva ."'cotia, v.hi; i wui ox-tit-mi-ly infcrestiiig, not only fivm its richness for •.oil, but as a specimen; "it showed the chlorite, .schi-f, q-iaiiz, ani the vein of gold.

Mr. Bran Hopkins had listens! with great pleasure to Air. PUilhps s pap-r, which left very little to be remarked upon, but spf akinir generally oa the subjest ol goid formations, and lhe system of-extracting it trom t!i_e ore, according to his own experience t!n v Jiad very little ditiicalty iv commencing m a go-d tieid to mid the gold, begini ins with the out-crop and washing out the gold from the debris. Apiiu 'with regard to the quartz veins, when the surface had i)een washed away, tht-y tound no difficulty whatever in extracting the gold from the quartz. Tlie Port Phiiii™ Company commenced their operations on a quartz vein, winch yielded on the surface lOozs. to the ton - it afterwards diminished to Gjzs., and as the quantity operated upon, and tlie depth of the workiu" increased, the average yield diminished ; but, in consequence of the iut.oduction of statnpi:i»- aud the blaiiKet system, as applied in South Americlthev ivere now able to make a profit with stuff producing only lOdwts. per ton, aud they, in South Atneri'-a" continued to make a profit with a yield as low as 6-lwts par ton, provided they got 2,005 or 0,000 tons of stuff permontliofthat average quality. They found no difficulty in getting the remaining gold from th? re mains ot iheqmrtz by re-treatment, aud thereof finer stamps At first, whon they used theClriian nulls witu mercury, they could not make^oz per ton, pay a profit. He was happy to say they could now^rk material yielding only 6 dwti. at a profit

The paper was amply illustrated by diajrrams prepare! by Mr. Ph-llips; the model of the " Welcome" nugget, and a larcce number of minerals bearing on the subject, %vere exhibited byPPot.i#ot. Ten-iant; and a workinjr molel ot the frold amaliramatin^ machinery invented by Mr. Joint Mitchell, F.C.S., was also in the room. The paper having been read, the President (Mr. Thomas Sopwith, AI.A., F.G.8.) said that he would bo glad to hear any remarks upon it from those present; anil, with a view of opening the discussion, he would request Mr. Mitchell toTdeseribe the model of his gold amaiirainntirig machinery. Mr. Mitchell paid that the object of the machine was to further crush the gold-bearins ore after it lefc the stamps. It was well known that it was necessary to treat it in a triturating machine of some kind, and a species of common corn mill had generally been employed ; he believed that the machine before them eifected the trituration far more perfectly. It -voald be seen that it was a modification of the mil! used for grinding coke for foundry purposes, and indigo for dyeing. The triruutor consisted of anr annular basin in which four balk v/ere placed, such ballsbein"- made to run round the basin l>y the four arms attached t« the cross-piece above. In this driving1, ho.vever, he had introduced an improvement. It was usual for the ball to be driven by the simple pressure of the straight ana again-t it, the consequence being that the ball running like a cart-wheel soon becomes oval. To remedy this evil the balls were driven, in his machine by small conical rollers placed at the bottom of tin; arms.the consequence being that the balls arc given a double motion r they revolved, as it were, on two

T!w Ciiiirman, in moving the vote of thanks, said he w:u care they would all agree with him as to the great vdue of Mr. Philii.is's paper ; he had seldom listjuwl to a papT in which a subjeethad been more ek-ariy brou.-ut forward. For his own part, he considered that the real interest of the subject rested upon the extraction of the gold, which occurred ia a state of very minute sub livision. since it was there that we uiu--t look for profits. Many of the remarks of .Mr. Phiilips's paper must beof the greatest possible use both to those supplying fa&ds for the v.'orkin£c of sold properties, and to the gold seekers themselves. He eousidtred th-it Mr. Pliiliios ha i l.ild the Society urider a great obligation to him. and he, therefore, asked them to give him th^ir best thanks. With respect to tlu peculLir contorted formation ref-rred u> by Mr. Philip?, he thouiht it was highly interestiiig, aad i.c v-onlti, in connection with it, remark that in the Inter-miuanal lixhibition, in the Beluiau dep-irtin«'nf, they would fiod maps of for-iiMTi-jus n»r-t «i!h in that country where the contortions were even still more remarkable.
