Mohave County miner., 1914-12-19
Vast Deposits of MoIybdenum.

Last Sunday in company of Robert c. Jacobson and Ray L. Dimmick the MINER editor visited the mines in the Copper Canyon and Deluge Wash sec tions of Wallapai mountains. At the Whale group of mines, now under op- tion to John H. Conway and operated under the supervision of R. c. Jacob son, men are at work timbering up the collar of shaft and leveling off ground for the installation of hoisting plant. A shaft is to be sunk to a depth of about 200 feet and drift carried north and south on the vein. In the bottom of the shaft, which is now thirty feet in depth, fairly good ore body is known to exist. This ore carries about five per cent copper and the same value in molybdenum. On the same vein an adit drift has been run 230 feet, and in the breast five feet of heavy copper ore shows. Along the drift are large bodies of molybdenite mixed with copper. The drift is about 150 feet below the apex of the vein, which is about twenty feet wide on the level, where the first crosscut has been run. Samples across this twenty feet of ore gave values of 14S in gold, silver and copper, the molybdenite not being taken into con- sideration in the estimate of value, although the value in this metal alone is greater than all the other metals combined.
 At the present time experiments are being carried on to ascertain the best method of working the ore and saving the molybdenum content. So far some excellent results have been secured. The United States Bureau of Mines is still working on the separation of the metals and feel certain of getting re- suits.
 At the Miller mines, in Deluge Wash, some splendid ore has been opened in a crosscut tunnel, which was being run to cut larger vein farther up the hill. When this vein was encountered MT. Miller drove drift a short distance on the vein and found some excellent ore. He has been trying different methods in hope of finding way to make a high grade molybdenum product and has secured some results by the use of an alkaline Notation.
 He claims that copper will not be fioated by his method and showed the party some of the rich concentrate that he had made by this method. He has several veins outcropping on his prop erty and has one vein fully forty feet in width that carries copper and other metals. On his other veins he has found the same rich molybdenum ores that occur in the properties of the Whale and Great Canyon groups.
 Of the three groups, we are assured by men who know, that there have never been found anywhere Assures containing so much of the rare metals. The U. s. Bureau of Mines has had men looking all over the United States for moly lybdenum and from this depart ment we have assurance that nowhere have such bodies of this rare ore ever been found. This Bureau, after visit ing the property, has been working on a method of separating the copper and other metals from the gangue, but so far with but small success.
 About month ago results were ob- tained by the Minerals Separation, the result showing a concentrate of so per cent, and worth at Yucca about 1400S per ton. As there are many thousands of tons of ore that will run about five per cent or better, it should not be doubted that some one will be found who will put in the necessary money to make these mines big paying con cerns.
