MoHAvE MINE HAS
 SPLENDID SHOWING


 center of attraction and interest in ,Mohave county just now is the mine and mill of the Frisco Mines and Power company, at Union Pass. For two years the New York and New Jersey men constituting the company have been quietly but vigorously de- veloping what is now believed to be one of the biggest deposits of free milling gold ore in the country. An so ton mill and cyanide plant have been completed, and though scarcely out of the experimental and adjust ment stage, the results of milling to date are such as to assure the ulti- mate success of both mine and mill.
 What lends unusual interest to the operations of the Frisco company is the fact that every feature, from transportation to mining, has been a distinct departure from the methods in vogue here, and through encounter ing great opposition the management has had the courage of it's convict ions, and as a reward has met with success in nearly every detail. To begin with, the mine is about fifteen miles from the nearest railroad point, Union, on the Chloride road, and abont twenty-five miles from Kingmau, the supply point, and when two automobile trucks were installed to take the place of teams for ord mary hauling, disaster was predicted. As a matter of fact, these trucks are still in operation and have saved the company thousands of dollars.
 The mine is developed by a series of tunnels and the ore has been so blocked out that it will all be handled through a single main tun- nel for several years at least. Hoist ing and pumping are entirely elimin- ated, and the character of the ore is such that outside of ehutes, there is not a single stick of timber in the mine The ore is nearly uniform in grade and the pillar system of min ing will be used, although thousands of tons can be quarried from the surface, all of which makes for great economy in mining.
 The mill is a departure from the stamp type in use elsewhere in the county and consists of Kennedy crusher, Hardynge Ball and Pebble mills, pulp thickening tanks, Pachuca tanks and Burt filter presses. The Hardynge mill and Burt presses are innovations in the district and their results will be carefully watched. The extraction is already 92 per cent and this will probably be raised 3 or 4 per cent with adjustment. A Gardner erusher for secondary crush ing has been shipped from New York and will be put in at once. J. R. Clair, president of the company, who has been in active charge for several months, left for New York, where the question of enlarging the plant to 15O tons will be taken up.
 While, mill and mine equipment for the most part represent what is latest and perhaps best in mining opera tions, the feature of the Frisco plant 1: that is most important and whose re suits will be most far-reaching, is its power plant, two Meitz-Weiss crude oil internal combustion enginess of so and 50 horse power each. When the local power house was put into commission about a year ago and electric power was delivered into the Gold Road district, at about half the former cost per horse power, it was believed that the last word in cheap power had been said. Now comes a crude oil engine, which in turn again , cuts nearly in half the cost of power. Its consumption of fuel is almost incredibly small, a little less than one pint per horse power per hour, and costs, laid down at the |, mine, after fifteen mile haul, from the railroad, a fraction under cents per gallon. Judging from the tests of the past two weeks these crude ' oil engines are marvels of economy and efficiency and should revolution ize mine power throughout the South : west.
 The Mossbaek group of mines, owned by the Gold Reed company, has been bonded by T. s. O'Brien, acting for New York men. Water will be drawn from the 300 foot shaft and development started at once. The Mossbaek is one of the biggest gold bearing veins in the San Francisco district, 20 feet of its croppings av- eraging SIP per ton. A crosseut on tne 30O foot level ebowc an Ore hOdy
