Mohave County miner., 1911-06-03

carrying on the average 2.44 ounces Of gold to the ton, and large portion of which is iron oxides, sampling POS. 1858 to the ton. On the 635 and 475 foot levels. in the same shoot, the ore shows the same thickness, samples of the averages of the drifts varying from one ounce to 2.16 ounces in gold, the sulphide ores assaying as high as 7OS to the ton. The shoot is exposed a distance of 400 feet in the 400 foot level, 3l4 feet in the 475 foot level, I64 feet in the $50 foot level, 131 feet in the 625 foot level, and 143 feet in the 700 foot level. A peculiarity of the phenomenal shoot is that the values snow persistent increase with depth. The ore is in the same geo. logical formation and similar in character as that of the famous Con- gress mine, which it parallels a half mile south, and the possibilities of the property can hardly be overestimated when it is considered that the Con- gress mine continued to depth of A. 900 feet on the incline. Operators who have had charge of the Congress at different stages in it's development positively assert that the showing in the 700 foot level of the Alaska is bet ter than in the Congress at the same depth.
 As a sequal to the recent develop ment the United Gold Mines company is preparing to increase the capacity of it's thirty ton plant to one hundred tons, the tonnage in the mine insuring an ore supply for plant of this ca pacity for a long period. The drifts are now producing enough ore to sup ply the mill without any stoping. From fifty-five feet of drifting done last week car load of shipping ore was assorted in addition to the ton mage treated by the concentration and cyanide processes. Only two miners are employed on day shift and one at night in each drift, so that the amount of ground broken by such small force is almost as remarkable as the rich ness and continuity of the great shoot, considering that the greater portion is ore.
 The development of this wonderful property from a mere prospect into the high place it now holds among the gold mines of Northern Arizona, was under the management of D. J. Sul- livan, former county assessor. Since acquiring the claims in 1896, oyer 3OO,- OOOS has been expended in purchase price, development and equipment, under his direct supervision. The company now owns 5000 feet of the Alaska vein, some of the claims cover. ing a portion of the town of Congress. The vein has an easterly and westerly trend, dipping about B degrees to the north, with the great ore shoot inclin- ing to the west. Mir. Sullivan has always maintained that the property would, with development, prove a great gold producer, and now that his judgment has been vindicated, he is naturally jubilant. He financed the operations until he organized the com pany, of which he is president, general manager and one of the heaviest stock holders, and is now arranging with more pretentious plan than ever be- fore. By far the large part of the amount expended was for development, as it was always hls policy to prove a mine before erecting a plant larger than justifable by the tonnage in sight and available for treatment.
 ''It is better to have too much mine than too much mill," he said, yester- day. II am satisfied that the amount of ore now in sight would justify a plant of over one hundred tons capac- ity, but I will confine the installation of additional units to a hundred tons, and continue development of the great ore shoot, preferring to have the ore supply exceed the capacity of the mill, rather than vice versa"
 E. L. Bartholomew, superintendent, and in charge of operations, is miner of many years and almost worldwide experience. To his ability and energy is due, to no small extent, the head way being made in the mine. He took charge last December and having had charge of the Congress mine from the $50 to the 1000 foot levels, recognized the similarity of the ores at once, and the great possibilities of the Alaska Since assuming charge he has pushed the work with the energy and ability
