DEVELOPMENTS OF THE PAST WEEK
 IN THE KATHERINE GOLD DISTRICT
By William P. De Wolf.

the Gold Chain and the Adams, have reached an interesting and important stage of development. At the Gold Chain approximately 100000 tons of milling grade ore have already been opened at and above a depth of 100 feet, while at the other three proper ties mentioned the work now being done bids fair to result in the opening of ore bodies of great value and large proportions.
 North of the shaft on the 250-foot level in the Katherine Extension workings the crosscutting of what is believed to be the continuation of the Treasure Vault vein has been com pleted. It has width of 60 feet and the ore is identical in appearance with the ore opened south of the shaft in the Treasure Vault workings at a depth of 55 feet. South of the shaft on the 25O-foot level in the Katherine Extension workings two shifts of miners are driving the crosscut at the rate of feet day to connection with the northeast continuation of the Katherine, or main Assure of the dis trict. The heading is showing in creased naturalization from day to day, which would indicate that the Katherine vein is being neared. The conditions in the Katherine Exten- sion workings are of more than usual interest to mining men as they hold forth the promise that two large and well paying deposits will soon be opened-one to the north the other to the south of the shaft.
 Development at depth will be start ed at the Treasure Vault property as soon as the machinery requisite for that purpose has been installed. The objective is depth of 500 feet. Lat erals will be run out to and through the Treasure Vault vein at 100 foot intervals as the shaft is deepened; and at depth of 800 feet a long drift will be extended in the vein to the point where it intersects the rich Katherine Assure. The crossing of these two veins is within the boun- diaries of the Treasure Vault estate. At the nearby Katherine mine 25 horse power engine has been installed to temporarily take the place of the 225 horse power engine that was wrecked at the time of its try-out. Sufficient air is now being furnished to keep the workings in the winze be- low the 400-foot level free from DOW der smoke. Ore conditions in the drift at depth of 100 feet in the winze are reported to be better than at any other point in the mine. The importance of this statement is bet ter understood when attention is call ed to the fact that in the main, or shaft workings there are lenzes of ore having value as high as $221 .O0 gold ton.
 The vein has been entered on the 2OO-foot level in the Adams workings, located about two miles to the north of the properties before mentioned, The ore body at this time has been erosscut 70 feet and it is reported to pan gold freely. Where opened on the 100 foot level in the Adams work ings the vein is 85 feet wide and car ries considerable gold in the free.
 At the Gold Chain mine the shaft is nearing depth of 200 feet and from a point about 25 feet below the 100 foot level is being carried down in the valuable Gold Chain vein. This vein has width of 46 feet where opened east of the shaft on the 1OO-foot level. Representatives of the com pany who were here recently stated that 100-ton mill for the property is being considered.
 Don c. Aldrich, we'll know Nevada and California mining man and brok- CT, was in the Katherine district few days ago for the purpose of in specting the Sunbeam property. MT. Aldrich came here as the representa- tive of w. J. Loring, well known min ing engineer. He expressed himself as we'll pleased with the ore showing at the Sunbeam and stated that al comprehensive campaign of develop ment would be inaugurated on or be- fore February 1st.
 The Katherine Victor property, To- cated about 5000 feet from the Gold Chain, is being financed in" the east and will soon be undergoing develop ment. In addition to the Noontime group, located near the Gold Chain, the management of late purchased claims endlining the Tyro property and connecting with the Frisco prop erty. The management has also ac- quired 4 claims in the vicinity of the Sheep Trail mine. The Sheep Trail has produced considerable high grade ore and is owned by the same people who own the Katherine.
