WEEKLY MINING REVIEW.


 Tombstone community have received for the past few years. This discovery was | known to us in time for publication yes- terday, but we thought it advisable to have nothing to say about it until authentic | confirmation of the report was received The strike, as will be noted below in our regular report, was made in the south di'il of the GOO foot level. This is the greatest | depth Tn which ore has been discovered in the camp, and of course it is prima facla evidence of bodies of ore at the same depth The location of the strike is exactly on water leve! and hence it's eX,reras import ance While all competent geoiosists and practical mihing men have reiterated that the great wealth of Tombstone was beaeath the water level, still there were some skep- tics who had an idea that the great ere bodies did not go below 300 feet. But now the vista is clear; the pe1mansncy of Tombstone is established beyond dis pute; the richest body of ore yet en- couatered has been found impregnated with water. This will lift Tombstone from the slough cf active expectancy to the throne of actual certainty. The quality Of the orc discovered is of very high grade, containing large visible sheets of native silver, and large quantity of horn silver, besides not inconsiderable quantity of gold. The other mines of the district are maintaining their reputation, as the bullion report, which VIC publish below, so far as could be ascertained, can prove. The Grand Central, the next door neighbor to the Contention, is actively crosscuttihg on the 600 level and it is only matter of few days when we can duplicate to-day's news from the latter for the former. The Tranquility and Empire are still on the ad- vance and give every indication ot contain- ing immense bodies of ore. The Ingersoll Stonewall and Randolph, in the western portion of the district, give encouraging reports, as usual, and the number of new claims bounding into realms of activity can have nothing but cheer and en- couragemcnt for the future of Tombstone. Below we chronicle the latest reports from the mining world of Tombstone district:
 CONTENTION.
 The bullion output of the Contention mine for the month of July amounted to $14S,0i7.43. The works heretofore report ed are being vigorously continued. The stopes show an immense quantity of ore in sight Late Tuesday night rich body of ore was struck in the south crosscut on the 500 level. Some days previously q body of ore was encountered in the north crosscut on the same level, thus proving that the vein is continuous. Prof. James, while ad- hitting the strike, was not inclined to give much information concerning it. but from undoupted reliable information gleaned elsewhere, we are in a position to assert that the new strike is one of immense magnitude. The big strike was made in tho south croSscut of the 600 level, the night before last, but ore not of such high grade was discovered in the north crosscut of the same level, several days ago. The ore in the south croSscut, which is at water level, is completely covered over with a coating of native silver, and assays away up. This may be considered the most important development yet made In Tombstone district The stopes through out the mine are looking we'll and the usual quantity is being shipped to the mill on the river. Several thousand tons of second-class ore still remain on the dump, and ten stamps of the Girard mill are still employed.
 GRAND CENTRAL.
 The crosscuts on the 400 and 600 levels are still being vigorously pushed, and though the indications of ore bodies in the immediate vicinity are good, nothing of importance has yet been struck. The stopes throughout the mine are in excel. lent condition and there is any quantity of ore in sight. The usual quantity of ore about 90 tons-is being shipped daily to the mills, and there is sufficient ahead on the mill dump to provide against delays in the rainy season. The bullion output of the Grand Central for the month of July was $100,000. The slight falling off was in consequence of shipping a large quan- tity of second-class ore that was in the way of some improvements that were ne cessary to be made in the dump at the mine.
 TRANQUILITY.
 This mine still keeps up its high repu- tatlon. The works heretofore reported are continued. About thirty tons of ore are hoisted daily from the whip shaft. The steam hoisting works were started up on the first of the month. Crosscuts are being run from the 115 and 300 levels; that from the 300 expected to make connection with the whip shalt, and the one from the 115 is expected to strike the ledge about twenty feet further. The body of high grade ore, referred to heretofore, is holding out we'll and expanding as development progresses. Ten stamps of the Girard mill are working on Tranquility ore, and when connection IS made with the works from the whip shaft and ore can be hoisted with more rapidity, it is expected that the entire power of the Girard mill will be devoted to Tranquility ore.
 HEAD CENTER.
 This mine IS working along as usual, without serious change. The usual quan- tity of ore is being hoisted and shipped to the mill. Stoping is mostly confined to the first level. The steam hoisting works will be in position in a few days and vigorous work may then be expected. The bullion output of this mine for the month of July amounted to S2l 600. This does not represent the entire month as the mill had not far start with the month
 OLD GUARD.
 Stoping is vigorously prosecuted in the so level, and a fine body of high grade ore has been opened up Several tons of ore I
