 Good Country.
 The San Juan is in a good country The country is granite and DOT phyry, with occasional shales. and there is considerable lime. There lis good deposition of mineral in the porphyry. but the principal vein Is q Assure in the granite. At the surface on discovery this Assure shows to be about 3 feet in width. and is clean. The copper at the sur face was high grade. lower. however, and to the present depth of 36O feet it runs low grade. probably an average above 9 per cent, but the bodies are larger. On the POO the deposit is above 90 feet in width all ore. The general opinion Is that the San Juan has not sufficient depth at this time, and that the principal ore bodies will be from 800 feet downward. This might be elassed with the property of the Irishman in Idaho. He had gone down a few hundred feet with good ore. when be got a lot of money to help in the development, and he sunk to GOO feet. and got large quantities of ex- cellent ore, the mine having paid ever since. However, when he struck this ore at depth the lrishman said; I "Jasus; I always knew it; but I'm awfullv afraid" Afraid of what?' someone asked. Afraid" said Pat, that the dommed Chineemen have been raising on the same vein and hat they have more of it than I have" Depth, in other words, would bring the San Juan into fine paying proposition. There are several thousand feet of underground ! development on the San Juan, and ore has been uncovered in many I places. Just before reaching tfe 309 body of water was tapped, which eliminates all future worry for water for the mill.
 The plant is equipped with a 50- f horse power boiler, hoist, air com Il presscr, and there is an lngersoll machine drill. The concentrator is E 300 feet down the hillside from the power plant, and has capacity of 5e ! tons 8 day. The mill is equipped with 2 5O-horse power boilers. The ! flow of the material was over griz- E zlys to crushers; thence u6 trom- E mels; oversize from trommels to E finer crusher; and then all to a Huntington mill; thence to two F i-con1partment jigs; thence to 3 VII Geys, and thence to a Johnston van ner. The saving was excellent, and the product averaged 30 per cent copper. The concentrates were shipped to the Old Dominion smelter at Globe, as well as the high grade
 which after hand sorting was ship ped raw. The ore is chalcopyrite and there are bodies of glance, arsl

 Lone Star.
 | Three miles from the San Juan is the Lone Star Consolidated Copper
 eompany's property which is idle tnow, and in charge of Charles Bald win as a watchman. The assessment
 work is done on a continuation oi
 a long tunnel. There is good
 showing here.
 The Horseshoe. in the same dis
 trict, is closed down also, though depth of 700 feet has been attained
 Billy Johnson is watchman. The prop erty is owned by the National Mining 7 Ap4BAdllDn 1Of DL DOSAbtAs anu ~ Is understood that work is to b'
 resumed soon. The property ha. 1 been shut down for a number O 1 years, but as the owners are securing | patent it is certain they will no much longer hold off from develop ing. The same people own the IroI
 Cap mine at Globe. The Horsesho'
 is a big blowout With little deptl 1 it was discovered that the horse l shoe" was a circle and continued
