Prom Thunday's phily.l Mining Review.

Mining matters for the year 1875 do not make as good showing as they should, for the reason that the assessors in Yavapai, and probably other counties, did not gather the statistics required by an act of the last Leg islature. We have only partial report from the assessor of Mohaye county, from which to collect reliable data
 In Mohaye county, there were in operation during the past year, four arastras, three furnaces. and one quartz mill. The mines are but a short distance from She Colorado rlver, and considerable rich ore has been sent to san Francisco and sold The mines from which ore has been worked, of which we have knowledge. were the Sixty-three, LlttIc Chief, Cupel & Tiger, Jackson, New Era, Diana, Keystone, Arnold, Sunday School, Silver Hill and Chas Gross-tweIve mines from which the gross yield Is reported at SG6. 800. As several of the mines have only shipped few tons of ore to acertain its value, the yield is good indication of the richness of the country. Many very rich mines have been discovered in the country during the year and considerable work done on them, but owing to the lack of mills or other reduc' tion works, little ore has been worked.
 In Yavapai county, little progress of note has been made.
 There are eight quartz mills, one steam, and three water-power arrastras, and about twenty horsepower arrastras in the county. Five of the mills, owing to Indian troubles, sulphurets in the ores, and the drouth, have been idle most of the time for three years, and the re;icencc of the owners of those in operation, prevents a statement of the actual results, which we estimate from such inior nation as is at hand, to be about S55,OOU in gold. More details from the arrastras have been received, showing the amount produced by them to be about S23, 900. Tue year was very unfavorable for placer mining, water being very scarce, except for A few weeks in summer during the prevalence Of thunder storms Yet few men have been steady at work on each of the auriieruus streams, and at the dggings at Weaver and Antelope Hill. The gross amount of placer gold received by merchants at the various points of supply, was but little over s300Oo. Thus our total production of gold for the year xill not ex- ceed Sll0,00O
 No reduction works for treating silver ores have ever been erected m the county, though experience shows that silver IS the predomi- Dant metal in our mines, even m those which have been worked only for gold.
 Since the Tiger silver mine was opened, something more than year ago, thirty five tons of ore have have been shipped to San Francisco and there sold for Sl6,455l4, (coin) yield of $40 per ton. Upon the dump at the mine there are about 800 tons of ore, selected for working, which is estimated to be worth between so and Sl00 per ton. It Is known that the mines in Yuma coun. ty have been protitably worked, and the ore shipped to San Francisco, but no statement of the amount realized Is at hand.
 In Maricopa county, parties have been de- veloping several valuable silver mines, but no ore has been reduced that we know of.
 Considerable energy has been displayed in Pima county in opening old silver mines near Tucson, and in the eastern portion of the county, in working copper mines. The latter enterprise is evidently paying one, but no | figures have been furnished.
 | Although so little has been accomplished our mining community is in better spirits than ever before. The subjugation of the Apaches leaves the field open to prospectors and enables men to work at less expense than formerly. number of enterprises are on foot looking to operations on large scale, with sufficient means, and we are expecting, this year, the commencement of prosper. ous mining era in Arizona.
