short years ago little inkling of what was to come had been revealed accounts to convey to those unable to visit the property some idea of the magnitude of its operations for a brief statement of the early history of the company we are indebted to the third annual report of the company issued in january 1908 in which Q C macneill the organization of the original utah cop copia per company in 1903

all as a spectacular mining undertaking the information contained in this condensed review is taken mainly from annual reports issued by the company which of late years have been very complete and replete with illustrations which serve president of the company thus sums up the facts for the first few years of operations early history the area of about acres of ground embraced in the companas comp anys holdings of mining property has been known to be copper bearing for a number of years but was not taken up for active development until the development of the mine was commenced in november 1903 and the mill began its operations in april 1904 since that time this experimental plant located about three miles down the canyon fron from the mine and known as the hopperton copperton Cop Copp ertol plant has operated continuously and has been enlarged and improved from time to time until now 1908 it has a capacity ol of out tons a day the operations and metallurgical re ailts of the experimental plant were such 3 to warrant the company early in 1906 L making the necessary arrangements to abild lild a much larger plant on account of lere acre being no suitable location in bingam

properly opening up the ground for the application of what is known as as the caving system of mining up until june 1907 all the ores extracted were derived from development work and by the application of that system the entire mineralized area of the property is covered by a considerable thickness of low grade and oxidized ores after consultation with various specialists it was determined to adopt the use of steam eral manager D C jackli jackling ng in this same report says the ore bodies of the property consist of an altered porphyry containing small grains of copper minerals very uniformly disseminated throughout the mass both in fracture seams and in the body of the rock and average about 2 per cent copper ounce silver and 0 ounce gold the primary copper mineral
