Scottish Corporation the First to Solve Problem of Profitable
 Handling Low Grade Ores

lember oOlh, l9l4, when Its annual report was rendered and producing in an even greater volume during the late spring and summer months of this year, Arizona Copper Company main tains its right to be ranked among Arizona's foremost producers as wei. as Co be termed tha 'Pioneer Por- phyry of America a title long since bestowed
 It is true that during he last part of 1914 and early in 1915. output was curtailed at the Arizona Copper Com pany mills. but such was also the case on the properties of every large copper producer in the country. The outbreak of hostilities in Europe had exactly the same effect on this conn pany as it had on an the others Since January l Of this year output wa steadily increased until such increases had become highly important. Such in- creased production was continuing when the Western Federation of Min. CTS brought about the strike that re-. suited in a determination to close the plant rather than to submit to the d.c- tation of that body

 Opens Way For Others.
 As has been stated above Go AIizoul Copper Company and to Clifton 50 ,uJ credit of solving the problem of haud ing porphyries. It was this company that erected the first cOuceurpt0r conducted the first experimentation and made the first success of handling low grade ores with profit To tn, experiments carried out and the meth ods proved by this company all the porphyries" of thc west now oWl the dividends they are paying. To it. efforts and to the result of the proof. this company furnished, thousands up pon thousands of operatives iu Utah Nevada and Arizona owe the fact tha they have found employment in mine. that were previously considered as l0E grade as to Doe worthless. u ia true that Arizona's accomplishments have been to a large extend lost sigh, Of I the rush to the ore of other low grade mines of Utah and Nevada, but the fact remains that it was Clifton and the Arizona Copper Company lla bIazed he trail and showed the way for those pew corners to the copper game.
 Difficulties Overcome.
 The Arizona Copper Company under took the mining of copper under grea. difficulties and was successful Later it continued copper production in the face of what seemed certain failur. and made success for itself and the other Flow graders. It started with g high grade proposition, in an isolated country without railroad transporta ton, where black copper matte had (, be hauled by wagon 700 miles or moro into Colorado. Clifton was a rich "sur face camp and it remained for Ari zona Copper to prove that the req wealth of its own mines, the req wealth and merit of the district wal not in the high grade ores, that wer' there in limited quantities but in th' vast low grade ore bodies that were found in its explorations. These wer' the problems that were solved by th' nerve and resourcefulDess of the man agemont of inc company made mp 1T Scotland where the vast majority O it's shares were and have always beer held.
