Mining Property for Sale. A Two Thirds Interest OF THE Golden Rule Mining Company’s Claims and Mill, Situated in Tuolumne County, California, two anda half miles south of Jamestown, on the Great Mother Quartz Lode, A good 15-stainp Water Power Quartz Mill Issituated on the property, with a never-falling supply of water, ag ean be shnwn by the last four years continual running. This Claim has three paraltcl Ledges, from 60 to 100 feet “apart, averaging from two to six fcet in width, wlth alength of six hundred feet. They areso situated that a tunnel has heenrun through them at right angles, making a surfaco drainsge of from seventy to elghty fect In depth on the mine. The mine Is well ventilated by shafts from the surface, and well timbered so far as worked. In the mine are steam Holsting Works, capable of holsting from a deptb of S$)0 tect. A torec of hiitcen nen only are required to keep both mill and inine running regularly. On te surfuce und tlacs lor a distanee of 503 feet from these veins, the ground or surface wus mined by plaeer miners, 1u former scars, produeing from two tu tive ounces per day1o the min, ducing the season when watcr eould be obtained, which taety.e3 10 prore that a heavy deposit of ore was once contuitud in the croppings ot tliese shutes, which, by all toriner and present theories of deop mine workings, came lroin below, indicating that when sunk upon tu n proper depth, the lead will develop a mine equal to the Amador or Burcka. This elaim has pald Its 19th regular dividend of $1,500 each, during the pasttour years, besides all tho eonstruction and other expense account, and has ievled no assessments during the same time, and at present has on hand $8,000 In the Treasury, and no debis. The last level, 150 feet trom the surface reek, averaged $7 per toa, on Which was a prog of from $1 tv $1 50 per ton.

Many machines have heen tried, RECOMMENDATIONS: San Francisco, October 19th, 1868. Mr. M. Huxorrrorv—wear Sir :—We havo had twelve of your Concentrators at work at the Oneida Mine, Amador County, for about six months. They give entire satisfaction. They are strong and substantial, requiring, thus far, no repairs, nnd do their work thoroughly and effectively. Ata recent clean-up of four of them, I found that in four weeks’ time we saved about $500 in free gold, besides the sulphurets, or not far from one dollar per ton on the entiro crushing of the ten stamps connected with them. machines. Yours, respectfully, In my opinion, it is for the interest of every quartz mill to havo your GEORGE PRINGLKE, Supt. Oneida Mine. Orrice OF THE OnEIDA Minine Cosipany, Jackson, May 13th 1868 Mr. Morean Huneerrorp—Dear Sir:—In regard to the four Hungerford Concentrartors that I bouglit of Messrs. Goss & Lambard last month, I will say that I put thom up in the Oneida Mill soon after I arrived here, and find that they save sulphurets well and clean, and work to my entire satisfaction. I have tried many other concentrators, hut these stand up and work better than any others I have used. I have ordered Messrs. Goss & Lombard to make eight moro for me as soon as possible. Very truly yours, JAMES MORGAN. Big Oar Fiat, May 25th, 1868.—A/r. T. W. Alulford—Dear Sir :—I have used two of M.

A full description of the principlo and modo of action of this pan, is described in circulars, which will be forwarded to any party who nny desito thom. The Hungerford Concentrator has only to be scen to be appreciated. No millman will! use any other kind after ho has tried that. give perfect Satisfaction. They are in active operation in mills throughout the State, and It should he borne in mind that Mr. Hungerford is the onyinal builder and maker of the celebrated Prater Concentrator, nnd his name should be sufficient guarantee to warrant the public in examining his new machine before purchasing elsewhere.
