consequence of the increase in the price of mining equipment this company had to revise its estimates of the profits of working its immense low grade dumps and to close its mill in july 1922 in august 1922 this company had developed on its 2600 ft level some of the best ore found in the mine below the 1600 foot level the company began to ship this ore in 1923 but was also occupied in in sinking shafts to the 2700 foot level for cores driven in december 1923 toward the vein in advance of the installation of the pumps on that level indicate that better ore may be found there the portland

1923 the cresson mine had completed the installation of its new and hoist which is capable of sinking to a depth of feet and soon commenced sinking a shaft to the 1800 foot level production was maintained throughout the I 1 year from the 1700 foot level and above at the rate of tons a month excellent ore has been found on the 1800 foot level the ajax mine reopened in 1922 as the tonopah ajax

in 1922 to the companas comp anys magnetic separation plant and zinc oxide plant at canon city and in 1923 doubled its shipments of ore of that class as well as continued heavy shipments of pyrite silver ore to utah smelters shelters sm elters i the smuggler concentration mill at aspen a steady contributor of silver concentrates in 1922 1992 19 92 could not survive the decrease in price of silver with the end of the pittman dollar silver in june and ceased operations in august shipments of smelting smelling sm elting silver ore were continued from aspen throughout the year but in lessened quantity leadville shipments decline the shipments from leadville in 1923 declined when silver dropped to the world price and the pulling z of the pumps on the lower levels of the penrose mine in november 1923 drove the work to the upper levels in the down town co cos s property the decrease in the number of lessees lessels on the yak property in november also cut down the quantity of
