PROGRESS MADE ON MAGNATE
 |S RAPID
PROVISION M AIDE FOR TOWNSHIP WITH AMPLE SUPPLY OF WATER; AD- OPTIONAL EQUIPMENT BOUGHT FOR MINE
(From Wednesdays Daily.)

IWIn ButteS district, owned DE me Magnatc Copper Company, is attract ing the attention of mining men throughout the State. When it was announced a few months ago that Walter Harvey Weed had been em- rloyed by this company as consulting engineer and geologist, and that Her bert C. Shotwell had been engaged as engineer actively in charge of opera ,ions, it became apparent at once that inc properties of the company were to be opened up and developed in the most efficient manner
 Including claims recently purchased inc company holds group of % con tiguous claims, or about SIS acres, located 515 miles from the town of Twin Buttes in a direction slightly west of south. It is reached by a wagon road from Twin Buttes, a sta ton on an extension of the Tucson Nogales branch of the Southern Pa cihc railroad The altitude is, rough ly. $500 feet above sea level, and L. s. Mineral Monument No. is situ- ated on Hector No. 1 claim, which Is almost in the center of the group and is generally referred to as Magnate Ridge. The original location and de vclopmcnt work on number of these claims was done by A. C. Simkins, who is probably more familiar with local conditions than any one in Pima county.
 Provision has been made for town site, with an ample supply of water, inc construction of necessary roads and buildings, and the installation of additional equipment, and is being rapidly pushed. The actual work of development includes. cross-cutting and drifting from the present work ing shaft, and also the driving of a nCw tunnel, on which substantial progress has already been made. Drilling will shortly be commenced on the ridge above the shaft, and holes will be put down at 2O0-foot in tervals to find the limits and depths of the orc
 The following extracts are taken from reports of Walter Harvey Weed. f. M., made in September and Feb ruary, last:
 My examination of the 'Magnate group of claims made September 20, - l9l6, shows that the property is well worthy of exploration by churn drill ing as it has the distinguishing char acieristics of a disseminated copper deposit, so-called porphyry copper. cannot estimate the copper content CT thickness of the deposit, these fac tors being only determinable by drill ing or underground exploration, but the evidence disclosed by the shafts CT the property shows that a deposit of this character exists on the prop crty."
 "The six claims first examined in cluded about 60 acres of very promis- ilg-looking ground with the surface indications of a disseminated DOT rhyry copper, being of the same char acter as the outcrop over the Miami, Inspiration and Ray copper properties
 Besides this presumptive evidence of a deposit of disseminated ore, the ground contains several veins, one of which has been opened by shaft de- veloping commercial ore. The shaft, now l52 feet deep, shows copper ore which is being stopped The smclter returns from a carload of this orc shipped December %, l9l6 shows silver ounces per ton' copper 33i per centthe shelter value being Sl7.2l per ton"
 Another and larger vein cut across by the stream channel a hundred yards or so up the gulch looks fully as good and will be prospected as soon as accommodations can be pro- vided by workmen. These veins car " secondary copper ore similar in character but much richer than that of the blanket deposits of altered rock peppercd with tiny particles of copper glance forming the ore of the DOT phyry or disseminated copper de posits. The ore of the veins is, how ever, in part primary, that from the bottom of the Hector No. ? shaft showing chalcopyrite, which with the galena may be expected to continue downward to very considerable depth
 In preliminary report by J. Gary Lindley, F. M, on the six claims first acquired by the company, he said:
 "Ore deposits of the Magnate group differ materially in geological features
