[. Q. ). MINES AT STOCKTON HILL
 OPENS SENSATIONAL ORE ON 400

One of the most important strikes of ore in the county was reported yes terday from the c. o. D. mine, the headings on the 400 level being in big ore. In the east heading the ore av- erages BIO ounces silver and $16 gold for a width of 30 inches, while just back of this face the average across eight feet was 40 ounces silver and S3 gold, besides lead and zinc. Just how wide the vein is at this point has not yet been determined, the body having widened out beyond the two timber sets. In the west heading the ore is very rich, being dissimilar. to that in the east drift. As the drift is carried in the ore appears to be getting better with each round of hol- es. The length of the drift on this level yesterday was 660 feet, only slight break showing in the ore in that distance, and it is probable that even at that point (about 20 feet) the ore will be found outside of the drift. The ground between the 400 and the 300 level is virgin, no stoping having been done in that part of the mine during the old regime. Besides this great ore body there is large ton mage in the old stopes, much of 1t being high grade milling dirt. In fact only a small amount of the ma terial opened on the levels above the 400 have been stopped, the balance be- ing left because of the fact that the mining of the high grade for shipping purposes was what the old time miners were after, no ore below $6O being mined.
 As soon as the drift on the 400 is carried under the old ore shoot we expect still better ore will be opened, the main ore body in the old days run ming very high in silver. The devel- opment along this level has ., been really wonderful, there being close to S1,OO0,O0O worth of ore in sight be- tween the two headings and below the 300. With the other lifts being carried down 700 or 800 feet we eX- pect the mine to have few rivals in the state. The work of sinking to another level is now under way, the shaft being about 60 feet below the 400 level and going down rapidly.
 The c. O. D. is noteworthy prop erty. It has vein traceable on the sur face for more than a mile, the open ing on the Grannis claim, shows vein nine feet wide that carries good values in silver close to the surface, super ficial workings showing we'll min eralized zone. This opening is more than a mile from the main c. O. D.. shaft. In the lowest levels on the main property the vein is far wider and more potential as an ore bearer than on the surface, so that impor- tant ore may be expected at any point when the deeper workings reach out farther into the vein. ~~
 A three-compartment shaft is to be sunk on the vein as soon as the 400 level reaches through the old ore shoot, which will be used as the main working shaft and which will be car ried down to at least 1000 feet when the property is opened up along the old ore body in tn new levels. This new shaft is expected to pick up the ore bodies showing far to the east of the present work. This shaft is to be equipped with large hoist, compressor and pumps, all electrically driven. A steel headframe is also to be placed on the shaft, making it one of the most uptodate equipment in the state.
 This property is one of the most comprehensively equipped of any mine in the county, having a splendid electric hoist on the shaft, large con- pressor, sawmill, drill shapers and sharpeners, blacksmith shop, drill presses, lathes and every essential and necessary machine. Electric sinking and station pumps of suffi- cient capacity have been placed in the mine to take care of the constantly increasing volume of water. Camp buildings consist of boarding houses, bunk houses, administrative offices, dwellings for families, and well equipped testing plant where ores from all the properties of the com pany are tested out, assayed and pre- pared for the proper mill treatment. A transformer house and equipment is also one of the necessary features of the installations on the property.
 But the outstanding feature that catches the vision of the new man in camp is the big mill. This mill is the last word in mill construction. It contains. every device that makes for better saving and the economic hand ling of ores. From the moment that the ore is broken down in the chutes it automatically passes through every phase of milling until it lands on the tailings dumps divested of practical ly every particle of mineral content. This mill has a capacity of approxi- mately 125 tons daily. From the bunkers at the top of the mill the ore goes through the various machines,
