PFAU MINING CO.
 ID INSTALL MILL
On Their Cherry Greek
 Property.
Supt. -Ti1betts Returns from Ex- tensiVe Trip East Where He
 Purchased the Plant.

Supt. c. K. Tibbetts, of the PfaU Gold Mining and Reduction company, arrived in Prescott Sunday night iron an extensive trip to San Francisco, Salt Lake City, Denver, Chicago, Gin cinnati and St. Louis, where be had been on a trip of investigation for the company. When the company decid- ed that it would install a larger mill on its property on Cherry creek, they instructed Mir. Tibbetts to thoroughly investigate the different methods of treating the ore and to get the best and be satisfied with nothing else, and this trip was the result of this order.
 MT. Tibbetts is very conservative and careful man and was determined to thoroughly investigate all the different types of mills before making his selection. The plant purchased will have a capacity of 125 tons per day and it is what is known as the MerraII roller type. There will be two Of these roller mills, each having a capacity of about 65 tons per day. The values will be extracted from the ore by the cyanide process. In the system to be installed the ore will be crushed in the cyanide solution and transferred to the tanks with rotary pumps. After the pulp has been de- posted in the tanks it will be con- stantIy agitated by rotary pumps until the extraction is completed. After the extraction is completed the gold bearing solution will be trans ferred to Godbe separator where the pulp and cyanide solution will be separated, the pulp passing from the separator over amalgamating rifles where any coarse gold tbat had not been dissolved by the cyanide will be caught The gold will then be pre- cipitated with zinc dust and the gold shines collected in a filter press. This system is giving very satisfactory results wherever it is HOW in opera tion and MT. Tibbetts spent several days watching and investigating its operation. The system is absolutely automatic and only requires one man to handle the whole plant. This will be a great saving in the way of labor, which is an important item in hand ling big low grade propositions like the one owned by the above company.
 It will require four gas engines to operate the plant. The mill will re- quire a 5 horse power engine, the pumps and agitators a 30 horse power engine, the hoist and mine pumps an 85 horse power engine and the air compressor a 15 horse power engine. These engines will be the upright double cylinder pattern, constructed to manufacture their own gas from crude oil or untreated distillate.
 The new mill building will require about ten car loads of lumber in its construction and will be built with the idea in mind of handling the ore by gravity wherever it is possible. The company has one of the most ideal mill sites for such a mill that could be found in the county, and the water supply is many times greater than will be required. It is estimated that the present water supply would be sufficient to run 600 or 700 ton plant.
 Mir. Tibbetts informed the Journal Miner that since he left the property several weeks ago, small force of men has been working in the Valley tunnel where the enormous ore shoot was encountered about four months ago and that although the tunnel is in far enough to give them 65 feet across the ore vein they still have no foot wall. He also said the values We're getting little better. The tonnage of ore in sight in this oIe shoot now amounts to over POO, GOO tons, the values averaging a little better than 7.50 per ton. ? Work on the new mill will be start ed just as quick as the preliminary arrangements can be completed. | President Lee Pfau and a number of the officers and stockholders of the l. company are expected to arrive here soon.
