 Character and Value
 or the great ore tonnage practiod' ly one-quarter is carbonate, tnIce- quarter sulphide, the carbonate over. lying the sulpniGes. This ore deposit IS contained in monsonite, coarse grained pOrphyritic rock, this shud- ing into rhyclite on the outer rim o; the deposit. Conglomerate and gr4u. ite ore contacts here, while near by and continuing for miles. are huge up- ! lifts Of lava. An old crater mouth of large dimensions is seen a few miles to the southeast and sugge'ts how some of the lava material Of this sec- , ton was delivered The carbonate ores average about 5S per cent cop. per. the sulphides about l.5O per cen, copper. There are numerous branches of high grade copper throughout this deposit that were not taken into the estimate. Some of them show cop per running to 20 per cent. some have good precious metal values but nc account Of these have been taken into consideration in figuring on the value of the property.
 How These Ores Will Be Attacked
 The plan outlined for taking these ores Nas already been prl.tica.y ar range. Mr Michael Curlcy, Lake | Super,cr product who worked with Mi. Greenway at the Canisteo mines in Minnesota and a well known pro. ducer of satisfactory results in hand ling big tonDages of material, arrived in the Ajo camp in August 1912 and has been continuously in charge here as superintendent since. He is q pit man of large experience and he will be particularly valuable in the work to te performed here.
 The track to take out the carbon ate cres will be run in the gulch on the southwestern side of the main ore | cutcrop. On the opposite side of this |
 sulch there isalso ore to be mined. The track for the sulphide ores will re run alcngsise the outcrop on its southeastern side, from which level | plain runs for a distance These lines | will come into the main line at a | point some distance to the north where the flat door of the desert ex- tends for several miles. spreading out ,an-shaped from the mountains, af- iording splendid room for mills, town. site, and other things needed in the big plant that will eventually find llace here.
 As we have previously shown. e very large tonnage can be mined above the level cf the mesa on the southwestern side of the outcropping ore deposit. Aftep many years's oper- ation and when the steam shovels have taken the ores from depths as they are capable of some system will be adapted for securing the deeper ores. Mining in underground drifts connected with shafts equipped with large skips. or some bother plan that will pr duce low costs will be ob- served
 Iron Ore has examined many copper ore deposits. but none comparing with this in opportunities for cheap mining, and with the men here in charge, we know very fine results in mining costs will result. Nature has done its share, in making it easy and there are no grades to overcome in taking the ores from mine to treatment plant.
 The ores are hard, will probably not drill so easily as some, but they are Thoroughly fracturea and will break well and in sizes that can easily be handled by Gates or scme such form of crusher. In the ores are many small banded quartz seams and along the mineral has formed It Is seer in many distinct lines along the work lngs. Copper glance, and bermite are characteristic and general. It is thor oughly disseminated ore. too.
 Company Much Favored
 The Calumet & Arizona company was fortunate in having number of buildings to shelter their men while prosecuting its prospecting work. There were several adobe buildings in excellent condition. Some of these were plastered inside and out, made sanitary and comfortable. There is an office, engineering building, boarding house. supply houses, etc. No new
 builsings have been put up, scarce any expense incurred in this line.
 The Extent of Property Holdings
 The company owns outright about i,500 acres in this Ajo camp. It's min eral lands upon which the big ore tonnage has thus far been developed is all patented and the titles are ab soluteiy perfect Other lands have been purchased outright and others are now being obtained under the claim act, which requires $500 usually expended as assessment work on each claim. There is mineral being found on lands located still further north
