ORC BLANCO MINES.
Rich in Metals and Now Scene of
 Activity.

"The Gro Blanco mining dis
 trict Is coming to the front as a
 gold and copper camp" said
 Levi $. Davis, mining engineer, | who, with his partner, Lawrence A. Brasher. also a mining engi-
 neer, is in Ell Paso from that
 district.
 ''The Gro BlancO or White
 Gold district, is situated about
 85 miles south of Tucson over an
 excellent wagon'ro now pretty we'll cut up by the heavy traffic of ore teams, and 32 miles west of Nogales, and close by and
 north of the international boun
 dary line between Arizona and
 Sonora. It is also 30 miles from
 Amado, a station on the Tucson
 Nogales line, a cut off from the
 Southern Pacific railroad, and
 is in Santa Cruz county. It is
 also about three quarters of
 mile from Old Glory, which has
 the distinction of being the only
 pOStoffice named after the Amer
 ican flag.
 "The mines of Gro Blanco are in a series of low hills, called Gro Blanco mountains. The main camp is seven miles west of Arivaca an old Mexican pueblo.
 "Oro Blanco is one of the old mining camps of Arizona that has been dormant for 30 years, but which was the scene of great activity in 1880, during the old boom days of Tombstone. In those days the Apaches used to make frequent raids on this iSO- lated camp rendering it very un- safe for the early miners, which led to it's practical a abandonment. Indeed, they made raid on the old Cerro Colorado mine and massacred a lot of miners. With in the past two years the Sou thern Pacific railroad company | built a short line from Tucson to | Nogales, which brought the rail road within 32 miles from the | camp, resulting in a new invasion | of the district by mining men.
 "The district has now several | mines. Among them is the Austerlitz. a copper and silver property, which is ship | ping 50 tons of ore a day by wa gon. The Switz erland, which is the extension of the Austerlitz, is also now about ready to begin of copper and silver ores. There are also the Grub stake group, the Arizona COnso- Iidated and the Gro mines all in active operation. Besides these there are many prospects being opened up and nearly everything nas been located in the district.
 There are two mineral belts n the Gro Blanco district; one being the copper silver sulphide belt, which also carries some gold values; and the other called he gold belt" lying in the southern part of the district and the boundary line of Sonora. :-'
 ''In the latter belt are several yery promis ing properties, ,mong which may be mentioned he Grubstake group of mines, which is being opened up and operated by Lawrence A. Bra her and myself This proper y is now ready to begin ship nents of rich, all free milling ,old ore. In this group are four laims being opened up by a nain working tunnel following ( he Grubstake lode, and produc- ng milling ore the entire length with occasional risch ore shoots. )n this property are 1 2 large eins on the surface, running 1 ortherly and southerly. The 1rubstake vein is 32. feet wide l nd is paralleled by another, alled the Big Vein, from 45 to o feet wide. East of the latter nd pararell is the East Vein, bout 25 to 30 feet wide. All hese veins pan free gold on the urface. (
 In the Arizona Consolidated which the owner holds t the price of $25O,OOO, and the ( Tres Amigos and Gro Blanco t hines, there are two openings; t me, shaft POO feet deep wehich ' 5 in water. These workings ( re in vein 15 feet wide, of free $ nilling ore running $35 gold to I he ton. This lies east of, and the Grubstake mine.
 Another mine called the Gro $ nine, is now being developed ] " George B. William, and his (
