 Biggest Producers
Special to The Review

K1NGMAN. Ariz.. April l6.-Min- ing activity and investment interest in the Union Pass country tributary to Kingman, where Charles Sutro and associates of San Francisco are de- veloping the Katherine property in to one of the big gold mines of the west. continue to increase and are at- tended by favorable ore showings in a series of main and cross Assures which, would appear to bespeak the districts mining future. In the Ger bat Range country. where the Dud- ley interests have developed the c. o. D. property into a paying silver mine, a like satisfactory condition prevails. and in lesser degree the same may be said to the mineral belt in general that gfrdles this city.
 For more than a week the influx of mining men has overtaxed the ca pacity Of the hotels here and 10 re- lieve the congestion one local hotel management has placed two beds in each room The management ifas likewise telegraphed to Los Angeles for 200 cots. Some of the latter will De utilized in the corridors of the hotel and the remainder will be ship ped to the newly established camp is to be established. The townsite of Katherine has been laid out on property controlled by Charles H Mil Ter. a we'll known California and Ne vada mining man. and the lots are meeting with ready sale.
 Mine Is Described
 At the invitation of MT. Charles Sutro. who has just completed an in- spection of his mining interests in this section and returned to San Francisco. the writer visited the Katherine mine a few days ago and made a tour of the underground work ings. accompanied by Superintendent Ray Dimmick. The ore condition there are really phenomenal and stamp the property as twenty. sixty seven. fine" Both in the shaft and in the drifts the rock stands as solid as the facade of a church. without need Of support of stull or. timber. while the vein. 2 true Assure with feldspatic granite-porphyry walls. can be followed practically without a break from heading to heading.
 On the 1O0-foot level east. the ore shoot has length of 2S7 feet. breadth of from 15 to 8 feet. and an average value of approximately s11 gold a ton. There are wide lenses in the vein on the first level where the gold values range as high as $100 ton.
 The ore shoot east of the shaft on the 2O0-oot level has length of 53S feet. a breadth of from 31 to 67 feet and an average value of $14.45 gold a ton. The foregoing outlines the di- mensions and value of the shoot so far as it has been determined by crosscuts, raises and assays. It does not, however. take into considera- ton the ore that has been opened be- yond the point where the last cross cut was driven. although the vein continues on strong ana Wei-ueiih- ed with the face of the drift all ore.
 An idea Of the high grade charac- ter of the lenses opened on the sev- eral levels may be gained when 1t is stated that at point $40 feet east of the shaft on the 20-foot level that 16 feet of the vein has an average value of SIP gold ton.
 Sample Face of Drift
 In arriving at the determination of the value of run of the mine.' v ore as well as the value of the high grade. the management first sam ples the face of the drift crosscut. follows this by what Is termed "car sampling." and this in turn by jack
