ORC BLANC0.
One of ArizOna's Very Best Min
 ing Districts.
Outline of Features of the District Three Mills An Full Blast
 and More Coming.

In the Gro BIanco district Arlz7na has one of the best mining camps in the world. The breadth of this statement l fully realize, but the gold and silver in 5he hills there, the numerous excellent properties, the mills running and pro- jected, the developments now being made there all justify it. The only trouble with Gro Blsnco is that it is so little known. Colorado has her Creede and Cripple Creek and dozen other belauded camps that are better known right here in Arizona than our own Gro Blanco. Yet they do not excel the dis trict On the border one whit. If Gro Blanco was in Colorado it would be byword iD mining circles the world over. But it IS in a corner of Arizona, modest about it's merits, putting in its own good word when it can. to be sure, content to be obscure and prosperous. Miners there who are acquainted in Col orado say Gro Blanco is better than Crippi, Creek and away ahead in merit of Ore ,e.
 It was something of a revelation to me to learn what the real Gro BlaDco IS. Sales have been made there and openings of ore that l never expected. Nearly every property m the district IS under bond or with owners who have refused bonds. Every part of the dis trict has its mines.
 Of the mills in full blast there are three-the Montana, Yellow Jacket and Old Glory. Two more mills will short y be purchased, for the Gro and JuliG prop rty. under the management of William Hartt, and the Tres Amigos, owned by Nat Crocum, Martin McNa- mara and Preciliano Arballo. The Aus terlltz mill will probably resume work shortly, and now comes word that th Old Glory mill will shortly be enlarged to forty or fifty stamps, working every hing m the mine as 1t C mes.
 The OEO Bi.-uco district IS of two dis tinct festures-g, Ia ID quartz and gold in pOrThyry.
 
 termed quaTrlee. They are in reality quarrIes of ore on the crest of the hills. fhesa are fir, quently called "blowouts." GcOugh I have 1t from a competent geol- )gist that they are m reality the re- malLs of what was once regulation quartz vefns-and large veins The rock 5f the district IS unusually soft, and reg ponds quickly to erosion. The eros on 1f the hills, once higher by far than GOw, left the big lodges exposed and craggy. They fell about themselves, and as further erosion occurred, repeat d the process. The result I- that the ore is left in quarries and the mIners O. today are getting the benefit of the iso- Iation of the district for years gone by. Mining can be done in these open cuts under dollar for each ton.
 Prominent among the properties of his feature in the strIct are the Old Glory, Austerlitz, Mcdonald, Rsgnarock 1 and Sheltenbrand claims.
 The pOrphyry formations are a rey feature of the district, so far AS working them IS concerned. As early as ten years ago Mir. c. ". K mpton, mining engineer residing at Gro BlancO, had | noticed that ID the southery end of the | district porphyry leads were discernable l Little r nothing was done with them | at the time, however. It was only a | ear or two ago that work was gotten l under way on this class of rock. J. B. 1 had been advIsed of he | value of the porphyry about him, and | located everything about his ranch that l locked like porphyry. The result IS to- | day good group of properties. About | the same time William Wilde, an ex- soldier, while prospecting brought to light, mile or two south of McClana- i hans, another porphyry ledge, and de | veloped it into what is today the Bee | Hive, a property that brought forth | some ore going dollar a pound. A Int | lie later Lieut.. Leavell, in charge of the | escort of the international boundary found a porphyry lead south ward from the Bee Hive. His tind has a touch of the romantic. He thought of making his wife present of pin from gold found by himself in the hills. In Lis search be picked up what looked Ike gold rock cn the present site of the Mary Josephine. The pieces assayed V ell in gold and Mrs Lesvell was pres auted with pin therefrom. Develop ulCbto NClC lnSlildICO Ou bhO CllC Oy Lieut.. Leavell and other officers, with the result today of good mine of over 200 feet of development.
 Following the opehinR of the Bee Hive and the Mary Josephine the miners of tine d strict rubbed their eyes and began themselves to look up porphyry leads. Today they have the Tres Ami gos and the Sorrel Top, two splendid for which numerous offers tO bond by various outside parties hav- been refused. Porphyry carrying good god has even been found in the excs- vstions under the old Warsaw mill.
 The porphyry is very frishle. minng and milling easily and cheaply. l. one the Cru mistake, parts of It are 80 soft that he owne-, Col. Holden, works it n rocker. similar to placer gravel. He-ie mekin2 a good living thereet.
