III lIc last lullnIS SIdtiOII ol U4OAS O brief account was given of the Gates-Miles group of mines about 25 miles northeast of Yuma, and naturally follows g description of adjoining claims. The principal mine in the above mentioned group is the Grand Prize, and the Golden
 Gate, the property of NJ. E. Cum
 ningham, Max Cohen, William
 Minmack, John Shanssey, Gus Lewinson and Peter Burke, is an extention of the same ledge, Near by and owned by the same gentle men lie the Montana, Mammoth and Great Western. The Apex IS another claim located by the same parties excepting Burke. These mines, like the Gates-Miles group, are most advantageously situated for cheap development and reduction of it's ores at minimum cost.
 The Colorado river is only from one to two and one half miles dis tant, and there is an inexhaustible supply of wood at hand. Supplies can be delivered at mines and mill at reasonable cost, as the river steamers can make landing at any point on the river, ard tTansporta- tion from that point would cut but a small figure as an item of ex- pense. Bullion can be taken out any day and be delivered at the express office in Yuma in the space of an hour and Q half, by row boats Telephonic connection with Yuma can be had, necessitating but small outlay of money. In fact there never was mining prop erty more desira bly situated for economic working.
 The Montana and Great Western were located by other parties some thirty years ago, but were aban- doned owing to the high price of supplies end labor existing at that time, and, like 8 great many other discoveries in this western country, became "lost mines" until once more located by the above named gentlemen 1t the date of their first discovery, owing to the cruder and more expensive methods of re- ducing ores and the exorbitant supply rates, only very rich rock could be made to pay, while at the present time the great desideratum is to have extensive low grade properties with capacity sufficient tofurnish great number of stamps. Barring a little more wood and quicksilver one can operate twenty stamps as cheaply as ten, and the proportionate cost of reduction per ton of rock is steadily lessened as the number of the stamps increase. The ore of the above mentioned mines is low grade but there are immense bodies of it easy of hand ling, and the assays hitherto made average we'll
 There has been but little work done on these claims a5 they have been located but recently. There is an old shaft, ali in quartz, on the Great Western, 2 feet in depth, and sinking is being done on the Apex. The ore is all free milling being fria bIs and easy to crush, and having that very desirable ap- Dearance known to the miner as "rotten ripe" Gold is visible in it. and 1t horns out remarkable we'll. The owners of these properties pro- pose to develop them as much as their limitel means will allow, and then make some arrangement by which capital may be induced to take hold and make them produc- tive. Undoubtedly, judging from what is now in sight, they offer great advantages for investment. Of course no one can see into the ground, and there is &n element of chance always in mining, but there could be no better indications of permanency than exist in this camp. The formation is good, the ore averages well, the gold is evenly distributed across the Iedges, and the surrounding economic condi tioDs could not be surpassed.
