Show mm IN ALTA 1IEL PLEI1G R. L. Mack, Mining Engineer, Engi-neer, Tells of Late Developments De-velopments in Big Bore. R. L. Mack mining engineer who ia operating the Mack-Hanson lease on the Prince of Wales up Big Cottonwood, is in town for a few days, lie says that he is making a small shipment of $100 ore from his lease, which has been cut off from the market for some time by the enow. Mr. Mack visited the Alta tunnel on his way down and examined the fissure cut lost week. He describes it as a clean contact between the white and blue lime with one and one-half to two inches of oxidized vein filling. In hia judgment the contact is not one of tho mineralizing fissures, but is in close proximity to Buch a fissure. Just before tho contact was reached the white lime had a normal dip from the horizontal. After breaking through the vertical fault fissure the tunnel entered en-tered a decomposed blue lime and then disclosed the white lime standing almost al-most vertically. A big flow of water came in through the white lime, indicating indi-cating another break ahead which may be the Flora Hagen fissure. Beyond this is the crossing of the fissure from which Mr. Mack is mining min-ing the high grade. His workings are about 300 feet to the east and 450 feet above the course of the tunnel. The fissure in his lease has carried one to two feet of high-grade silver ore for several hundred feet. Mr. Mack is greatly interested in the showing at the Alta tunnel, as he believes be-lieves the property to be on the edge of important developments in a lower horizon than has ever been reached by any mine in eastern Alta. The Woodlawn, in Honeycomb fork, has been equipped with electrical power pow-er and has begun sinking a winze from the tunnel in low-grade silver-lead-zinc ore. Mr. Mack Bays its outlook for production pro-duction is excellent. |
