Mohave County miner., 1912-04-06
Activity in the Mines of Tonopah.

commenced at once upon the O. K. claim of the Tonopah Extension Min ing Company holdings. The new shaft is located 1900 feet west of the present working shaft and about l2,O feet due west of the company mill. It will be three compartment. The new hole is to be sunk to a depth of 1000 feet. The directors have had under advisement for some tune past the necessity of sinking another shaft, owing to the smallness of the present twO-compartment main working shaft, which is inadequate to handle the ore for their modern mill and the further proper development of the immense new ore bodies recently encountered under the able and efficient manage ment of John G. Kirchen. The new ore bodies on the 800 west level con- tinue in width and values. The ledge, which has been opened up to the farthest point west, is twenty feet wide and it's length will not be known for some time. This large body of high-grade milling ore, with the other bodies east of it, will necessitate a larger mill.
 This week the winze from the eX- treme north end of the north crosscut on the S00-foot level of the Rescue mine attained its first objective point, and cut the downward extension of the vein cut in this north crosscut Tn Septelnbe, last. The point at which this vein was first cut was 270 feet south of the north boundary line of the Eula claim, and the width of the vein was then said to be ten feet between walls, most of which was only vein material. but on the footv all side twelve inches of ore averaged 46$ a ton. This vein had an easterly and westerly course. and dipped at an angle of 30 degrees to the north, and it was calculated that it would be cut on the northern boundary line at q depth of about l20 feet below the level of the crosscut. It was encountered this week at depth of l25 feet, and the bottom of the wlnze is now twelve feet into the vein and was stopped be fore reaching the footwall, so the full width has not yet been determined Tonopah Miner.
 The great Belmont mire continues to improve as development and pros pecting continue. The new vein cut last week in south crosscut No from the HOO foot level has now been prov ed to be nine feet wide of good ore. This vein is west of the shaft in the ex- treme west of the Belmont vein and immediately east of the Belmont fault. No work will yet be done on the vein and it is one of fully ten different veins cut in various crosscuts north and south from different levels which will be further explored by drifts when time permits.
 The further development of the biz ore shoot above the first intermediate level of the Montana, Tonopah mine demonstrates that it is extending both east and west and that the full limits of the ore on its course have not yet been ascertained.
 It is now being opened up below by the raise from the 465,foot level and it's downward extension is again found ia the stope above the 5l5 foot level, where it has heretofore been describ. ed as the Mizpah fault vein in which very good ore indeed is now showing, although not yet as rich as in the big stope. The establishment of this fact IS most important, as, owing to the flat angle at which the vein dips, il will, when opened up, yield an i'm. mense tonnage of splendid ore be tween the 5l5 level and it's presen, depth of $50 feet. with an additional very large tonnage from that point uL to the cap rock, a distance of l25 feet
 The new vein on the 6l5,foot level continues to develop most satisfac torily. It has now been drifted or east for twenty-five feet and maintain. an average width of three feet anC average values of l50 ounces silver and from an ounce and quarter to ar ounce and half of gold, with piece. aScayipr ;,, I
