 Warren District
WRITTEN FOR THE MINING AND SCIENTIFIC
 PRESS.
Short Resume of Some of the leao' ing Properties, Exclusive of the Cop Per Queen and Calumet and Arr xona Mines.
Lowell Mine.

Lowell Mine.
 This property. purchased for s5ooi- 900 by the Copper Queen company in June, 1901. is situated little over a mile southeast of Bisbee. It is work ed through a vertical shaft about I120 feet in depth. There are nine main levels consisting chiefly of drifts from the shaft, and numerous cross cuts. The workings are probably entirely within Naco limestone, which Is cut by small dykes Of granite DOT phyry. The drifts in general follow the strike of the easterly dipping beds which are disturbed by slips along the bedding planes and by strike faults.
 No important ore bodies have been encountered in the Lowell above the 9O0-foot level. Ore occurs. however, on the 1000-foot and 110-foot levels, but has not yet been developed by stoping.
 At the time of the visit the mine was making about 175.000 gallons of water a day. mostly from the 1io-foot level
 Copper Kins Mine.
 This is an abandoned prospect a little over half a mile southeast of Bisbse. The workings comprise vertical shaft, supposed 10 be 700 feet deep, and sSneshort drifts The dump consists of hard, lfght- gray quartzone material heavily inf- pregnated with pyTite. The micro scope shows that this material is com posed chiefly of quartz in irregularly interlocking grains, with considerable sericite, pyrite, and little zircon and rutile. It is a highly altered rock and solar as revealed by its litho- ogical character. may have been or iginally either schist or porphyry. AS the shaft is sunk in the center of tLo area of intrusive rock, the material is probably alteder and minerallzed porphyry.
 .. .. Calumet & Pittsburg Mine. ..
 This property is about 3-4 of a mile southeast of Bisbee, near the road to Naco. At the time of the visit it comprised a well-eQuippei vertical shaft $50 feet in depth. No drifting has yet been undertaken and no ore encountered. The shaft is entirely in solid Naco limestone. There are no superficial indications of ore and the shaft has been sund with the expecta- ton of finding in depth a continuation of the ore-pearing ground that mas proved so profitable in the Copper Queen mine
 Lake Superiar and Pittsburg Mine.
 This mine, still in the prospecting stage, comprises two unconnected sets of workings, from shafts half mile apart.
 Whitehall Mine.
 The White tail Cor Whitehall Deer) mine lies about 3-4 miles south of Bisbee, on the northeastern edge of Espinal plain. It has produced a few hundred tons Of good copper ore forn. primitive and shallow workings on the contact between Abrigo and Mar tin 1imestones. The mine has been idle for years, but as it has recently been acquired by the Copper Queen Co. it is likely to be systematically explored in the near future.
 Uucle Sam Mine.
 This mine. situated in a gulch of the same name, lies five-eights of a mile southwest of Bisbee The de yelopments comprise a tunnel and 2 8 shaft, but as no work has been done for several years both were in- accessible at the time of the visit The dump of the tunnel shows evI- dences of considerable mineralization, and the mine is said to have produced IitIle good copper ore.
 Bisbee West mine is a prospect 2 miles southwest of Bisbee A verti. cal shaft about TOO feet deep has been sunk close to the junction of the Bis bee fault with a short northeast fault. The shaft was partly filled with water at the time of the visit, and none of the levels could be examined.
 Easter Sunday mine is miles east of Bisbee on the south side of Mule gulch. It has been worked on . small scale and in primitive manner. The development comprise a tunnel a few hundred feet in length run jnto a steep northern hill slope, and a ser ies of irregular stopes and raises extending up to the surface. The mine is unique in this district. inasmuch as it produces a free-gold ore The gold occurs rather irregularly in al fractured quartzite bed of the Aorita formation. The best ore is said 70 run as high as $50 per ton
 Glance mine is prospect miles southeast of B.sbee, near Glance sta ton on the E. P & $. w. railroad. It has a vertical shaft 505 feet in depth in Glance conglomerate. At zhe date of the writing the shaft had j.fst penetrated and reached the under lying limestone, but encountered at the contact so strong a flow of water that sinking had to be temporarily abasdoned. A drift has been run for 120 feet to the southwest. just above the water level. cutting through a dike of monzonite-pophyry about Is feet thick. According to a letter from, s. W. C1svson, portions of the dtks carry per cent copper. The Modern mine is prospect just outside of the Horfbern bouEdry of the quadrangle on the northeast side of Tombstone esDyoB, and is ia Pinal
