 ''The Middlemarch is located in the Dragoon mountains, nine miles west erly from Pearee. and thirty miles north of Bisbee. and is in the heart of the pioneer copper belt of Arizona The geological conditions are similar to those of many large producing mines. such as the Copper Queen and the Calumet and Arizona a. Bisbee. and the Cananea at Cananea. Mexico.
 The property consist of thirty-five claims, or an area of about 700 acres. Most of the development is on the Mis- souri claim, and consists of an incline shaft, drifts and stopes. The shaft has been sunk to the seventh level on an incline, reaching a vertical depth of 250 feet. making a total develop ment of 12,0OO feet or more At these workings the ledge has been proven to be fifty feet in width. There is a proved body of commercial ore of 75.- 900 tons above the fifth level. averag- ing 2.25 per cent copper. and nearly an ounce of silver The richest ore yet found is on the seventh level, the assays showing $40 per cent copper, 1.SS ounces of silver and fl cents gold.
 Since the company was formed last December. an oil notation plant has been installed. This method secures the greatest extraction from these ores at a minimum cost The mill was in- stalled under the direction of the gen eral manager. B. B. Snyder. mining en- gineer of this city. who was in charge of two successful fiOtation plants in Montana A Telsmith gyrating crush CT with a capacity of twenty-five tons per hour and a ball mill are part of the equipment. Power for the mill is sup piled by a semi-Diesel engine of 200 horsepower capacity. Actual opera ton has demonstrated an extraction of from 90 per cent to 95 per cent
 Tn addition to the low grade ore be- ing concentrated, ore carrying copper in excess of per cent. is being brok- en 0own from the face of a large body on the fifth level and shipped without selection to the shelter. materially in creasing the output of the mine.'
