MCCRACKEN SILVER LEAD COMPANY NOW
 HOO FEET ON VEIN

HUI TILL LIN V[M
 The mining editor visited the prop erty of the McCracken Silver Lead company this week and was much i'm pressed with developments that are being carried on at both the Atlanta and Otsega claims. At the Atlanta the tunnel has been carried in on the vein more than HOO feet, more than 800 feet being on the big vein. This vein shows excellent lenzes of high grade and the whole length of drift is in mill ore. Slopes have been opened in the property and a raise is being carried to the surface in big shoot of high grade material.
 At the Otsega the company has a shaft down 100 feet on the vein and drifts have been carried off 115 feet to the south and 150 feet to the north, all in exceptionally good ore. An adit drift has been carried in on the vein north of the shaft and glory hole opened through to the surface. from which a large tonnage of ore is now going forward to the mill. The vein at this point is 30 feet wide, streaks in it being solid galena, while the whole mass is of milling grade This ore shoot apparently is several hundred feet in length, running to a point near the apex of McCracken mountain, where it joins the veins on the Atlanta ground. Wherever open ed this great vein shows ore, values in silver in places running to above 100 ounces. The mill values of the great vein is about eight ounces silver and quite a percentage of lead. It'is our impression that with depth the vein will show greater values in silver with approximately the same values in lead.
 The company has it's big dry con- centrating plant in operation and can easily handle 75 tons of ore daily un- der present conditions. With some necessary improvements for the take off from the main concentrating ma chine the capacity could be largely added to. This improvement is now being worked out and will be put in within the next thirty days. The plant is making a splendid product, the values of the concentrates running about 60 per cent lead and 30 ounces silver. The mill is the Stebbins type of dry concentration, the ore going through grizzlies, rock breaker, coarse and finishing rolls, with conveyers, elevators and every device that makes for economy and the saving of values The one feature that stands out above the rest is the collection of dust. It would naturally be supposed that a dry mill would be one of the dustiest places in the land, but this has all been obviated by system of taking off the dust at each machine. The dust is drawn from the grizzlies, rock breaker, grinders and the concentra- tors by suction fans and driven off through pipes to point where it is dissipated in the atmosphere. Not as much dust may be found in this mill as is usually loosed in a wet plant From this point of view the plant is an ideal one. The saving of values is about 80 per cent, which is unusually high for straight concentration plant, no matter whethr it be wet or dry.
 As our readers know, the mining editor has always held a high opinion of the McCracken mine, believing that with proper development and the in stallation of mill of large tonnage it will be as big a producer as the Bunker Hill and Sullivan with greater values in its product. The McCrack- en vein is one of the largest in the county. It has immense values in sill yer in many parts, of the great vein system and the recovery of these val use offer no serious metallurgical problem. The only drawback that can be pointed out at his time is the dis tance from railroad and the absence of water, but these conditions can be remedied when the mines have been developed to an extent that will war rant the building of railroad and the bringing in of water from either the Big Sandy or the Bill Williams. As there is a practical certainty that a great power plant will be put in the Bill Williams Forks within the next year or two cheap power for all pur, poses will be right at hand, the .mines being only about ten miles from the Creek in direct line.
 J. H. Hoffman, secretary-treasurel of the company was in Kingman Wed. nesday of this week, having been out to the. mine on a tour of inspection and stopping over here a few hours while waiting for a train to Los An. geles. He is much pleased with con. ditions at the property and believes he is bringing in big winner.
