Mining intelligence.

the Calumet and Hecls company
 report: 'In it the managers have
 found their usual policy of conceal
 ment, and have told the stock
 holders nothing about their proper ty and its operations. The only in-
 formation IS the total quality oi
 copper produced and the average
 selling price. Not even the gross
 earnings of the property are stated
 and there is nothing to indicate what the expenses were. The cost
 of the copper is not given, and al-
 together the statements seem to
 have beea carefully prepared with a
 view to confuse the stockholders"
 A big mining sale is reported
 from RosslAnd, B. c. It occurred
 last Saturday, when the Center Star

One of them IS the Casper mine at Chap arral and the other the Gates mine at Silver Mountain. Contracts have already been let to sink 300 feet on the latter and 100 feet on the for mer.
 Michigan and Montana are begin ming to find Arizona a very formid- l able rival as a copper producer and | the ore from our sister territory is on an average much higher and | more easily worked than that from the northern states. The United | Verde nIine at Jerome, Ariz., now pays over A,OO0,OO0 per year over all expenses and Is one of the most noted copper mines in the world. This property was offered for sale Tor $l5,OO0 few years ago, but three times as many millions would not buy 1t now. It is also reported that .he Copper Queen mines at Bisbee will pay their stockholders S2,OOO,- 10 this year.-Albuquerque Dem ,rat. |
 The Copper Queen Mining Co, at oisbee, has put in machinery for the humiliation of the microbe infest- ng the water used by the employees. he water is put through a proct ss # distillation, then pumped into anks to cool. The water is also 'laced at the disposal of the public rec of charge.
 The Congress shaft has just been 1tended 150 feet deeper than for 1erly and they are now engaged in pening up the station at the Is5Os pot level. The Congress has prov n itself a good property in the ast and there IS enough ground al eady opened up ID it to keep it lnning for years to come should here never be another pound of re found in future explorations. Its istory however has been that ad- ltional ore bodies have always sen found with additional develop lent.
 The Western Mining World says: From Salida, Colorado. comes the port that there are now being 5 ade Tn that city a series of experi- ents and demonstrations of a new rocess of treating ores. If the sts made can be carried out on a rge scale, the industry of mining :: w grade ores will be speedily reyo- tionized. The process was dis 'vered and patented by A, G. ,ephen, of Colorado Springs, and ss already attracted no little atter f on from prominent mine and mill en. The process is described as ' 'ing similar to the cyanide, but assessing many superior points. 1t
 known as The Roasting etal Extraction Process All the etals are extracted by the ore solu- on and the ore is never roasted. Il, nPly crushed. The pulp is put ut to Vats, and the most refractory g yet tested requires only an hour d fifteen minutes to extract all etal from the pulp. Some ore re- EI IIres only thirty minutes, while the craze is about forty-fve minutes. IT 't only gold is thus taken from g ore. but silver, antimony, copper d sulphur. The presence of iron copper does not hinder the extrae- n of gold, as in the case with tbe anlde process, which will not sue 'siully treat ore that contains 're than three or four per cent of ID or copper. Another point is at the cyanide frequently requires elve or fifteen hours to treat ores 1t by this method is reduced in hour. The chemical used is six les stronger than cyanide, and It's to manufacture, even in small antlties, only two cents a gallon. E om 50 to 70 cents worth treats a l of ore."
