| others are preparing to do so, hence : it appears certain that the camp oi Katherine is to receive the degree of mining attention that is warranted by the ore-yielding potentialities of it's : numerous veins.
 loring Coming In
 D Within the past few days additional impetus has been given to mine devel opment at Katherine by reason of the probability that w. J. Loring, presi dent of the American Mining Con gress,, is to take over and develop a mining property there. MT. Loring, an engineer of international standing, is reported to have taken an option on the Probasco-Burt group of claims, located about 4OOO feet from the Gold Chain property. The Probasco-Burt group carries a vein so feet wide al surface that is said to assay from S4 to $40 gold a ton. At depth of eight feet the vein is said to assay from $4 ton across breadth of five feet. The transfer of the property to MT. Loring will be followed, it is believed, by the opening of paying mine simi- lar to his famous Carson Hill mine on the mother lode of California. It is said that shaft of 500 feet is to be sunk by the Loring interests, at the conclusion of the examination now be ing made.
 At the Gold Chain property a hoist and compressor have of late been in- stalled with view to mining develop ment at depth. A two-compartment shaft is now being sunk at point 125 feet below the tunnel level to tap, in it's dip, the big vein exposed at sur face. The massive uplift of the vein is fully 40 fet wide and is estimated to carry approximately 100000 tons of ore that can be broken and milled at a profit A recent sampling of wide sections of the outcrop gave an assay return of from S5.60 to s33.60 gold ton and from S2.00 to S16.32 silver a ton Development work is being done under the advisory supervision of Messrs. Shank and Shanklin, we'll known mining engineers with head quarters in San Francisco, and is in direct charge of F. c. Nourse. Nourse was formerly in charge of number of mines on the California mother lode.
 Pay Ore Is Opened
 Shaft work is well under way at the Katherine Extension mine and is be- ing expedited by the hoisting and compressor plants that were recently installed. The acreage lies between the Gold Chain and Katherine estates and is on the strike of the rich Kath- erine Assure. The objective is depth of 200 feet, where the continuation or the Katherine vein is to be crosscut and developed. The Katherine Assure is the mother lode of the district and is considered to have mine-making possibilities similar to those of the mother lode of California
 The fact that pay ore has been open ed in the Katherine mine in proximity to the Katherine Extension property adds largely to the value of the lat ter as a mining proposition. It also
  as the continuation of the Katherine vein extends on beyond the end line of the Katherine Extension property into the Gold Chain territory. Charles N. Miller, of San Francisco, who is in charge of the Morington placer prof. ect in the Feather River country of California, is backing the Katherine Extension venture. Development work is in charge of Sam Brethour. former ly of Cripple Creek, Colo., and Charles sherman, a we'll known Arizona min ing man.
