aemluated copper agd porphyry ore were in those days unknown. but the company had such ore a plenty and methods for treatment must be found lt was found in the concentrator and .it was proved that by great expendit lure for mechanical equipment and the | concentration of ore values. lower igradcs of ore could be handled, mined. ! ltreated. reduced and shipped. at a profit than had ever been conceived. When it was announced that it was possible Co handle ores of as low a grade os three per cent copper. the world doubted, but today nearly an of the low sraders" handle ore that is ! far below that percentage
 New Methods Needed.
 Having discovered the method for the profitable handling of low grade ores new and expensive machinery. buildings and equipment were ncccs- sary. The company was equal to the ] occasion and secured them With the new ore treatment plants in opera ,ion and in successful operation. it was tbc part of wisdom Co secure other holding of proven or probable value This also the company did It had entered upon a period of expansion which it continued It's already large holdings were sGU further largely in. creased, it spread ouj and grew. not only abou. Clifton but about Morenci and Nefcalf It Is the company that made the Cliuon-MorenciMotcalf dis Uct
 Builds Own Railroad.
 Even iu the early days Of the high grade proposition the company had borne In upon it constantly by reason a. tdc long haul that was required in Iac sd'pment or its ore that raiIw.r tram poration is indispensable to th, mining of the baser metals. When handling a low grade proposition Lhi. ."as more han ever manifest The .sca,hora Pacific was bui through the
 0uthwesL Connection with it was required end SO JEe Arizona Copper Company interests proceeded Go make the connection. They built a railroad from Clifton Co Lord burg N. ~. where it made connection with thc Southern Pacific Originally it was g narrow gauge line but later when the EI paso and Southwestern Railvsy was buiI. the A. C W. N. was contin Ucd on Go Eachi.a t0 connect with th. new railroad and was made standard gauge. The construction was am i'm. mediate expense Co the end of an ult- mate great saving and was undertaken as such in accordance with the gem eIal policy Of the company Its stand ariization was the same Later the , mine lines at Clifton and Metcalf were also standardized in gauge.
 To Clifton and the surrounding country the railroad meant as much as ir did 70 Arizona Copper Company. lt meant the opening up of that di.
 tricl it5 immediate advancement n . enabled other mining companies to make profitable shipments as weii r banished forever isolation from the world outside.
 Electrifes lts Mines.
 Another transportation problem which Arizona Copper Company solved for itself end others was the b use oi electric power for tramming , {, had large tunnel area. which per
 haqs braugH. the problem home to t 4 fLs mora. The experiment proved ar
 immediate success proving all that
 had promised for il as an economy
 Other companies also proG.ed by thc
 experiment but the Arizona Copper g. Company so extended it's system that s for a long time afterward 1t was tho |. recognized leader in miage of under. !, ground tracks operated by electricity |. In its main tunnel it went 70 far as D to take out the inclines that when in. 2 stalled were considered the acme Of transportation plans and through its |. 'elec,rdcation as such main tunne r IaChieyed stll greater savings
 Pioneering is Continued.
 Another piece Of pioneering which goes lo the credit of Arizona Copper | ls the saving ol copper that would ? otherwise go to waste in the mnc g waters It developed the system oi g |precipu tha, has since been pGt @ into general use by nearly an coppe I HIiNNn anu N NIlNN lANNIn 'AIf nN NAlL- ] of many thousands of pounds of cop -luer annually To them Another inIo Q yarion was the installation of syste l.

 These are only some of the example n of the progressiyeness of the company .fla few examples of its trail making and n path breaking that redounded to thl f benefit of others as well as Co its own a There are further proofs 10 the right of this company Co be termed a pio Ineer in economic mining methods O. ,. all sorts as well as the Pioneer Pol lphyry of America"
