GREEN MONSTER DEVELOPING
 HOLDINGS
(By William P. De Wolf)

ing shaft and the development of its property at depth, the Green Monster Mining Company will the current month begin mining operations on its holdings in the lower Verde contact in accord with the recommendation of A. P. Thompson, a mining en- gineer who recently completed an ex- animation of the geological and min eralogical conditions of that section and their relation to ore dispositions on the Green Monster Company's acreage. Thompson's report thereon has the approval of John Wellington Finch, the noted mining engineer Mir. Finch examined the Green Mon ster property last April, and in the early part of May submitted a report to the management which concurs with the plan of development drawn up by Thompson.
 Thompson's Recommendations
 The latter recommends the develop ment of the Green Monster vein. on the Green Monster claim, including the adjacent deposit on the Cliff claim: development of the outcrop of quartz and hematite at the southern end of the Revenue claim; develop ment of the iron-stained quartz blow out on the Protector claim, and. through the medium of crosscuts and drifts, development at depth of tho veins apexing on the Lone Pine claim to the south. He likewise suggests an investigation of the possible down. ward extension of the copper-stained | i fa,, sums up his conclusions as follows:
 General Synopsis.
 "The large. rich, copper-goldsilver ore bodies of the Verde mining dis trict, now being worked to the north and south of the property of the Green Monster Mining Company, arc undoubtedly contact deposits of pre- Cambrian age. lying near the contact of the Algonkian schists previously The outcroppings of these ore de posits, where they have been observ- ed. are bodies of limonite. iron-stain- ed quartz and schists.
 Warrant Development.
 "The property of the Green Mor- ster Mining Company is located in the connecting belt of schists and diorite which, on either side of the cont Dany's property, have been proven to contain high prade copper-gold-silvcr ore bodies. With identical relation ships of the ore bearing formations and with surface indications similar to the producing mines of the dis trict, the prospects for discovery of commercial ore bodies on the Green Monster property are encouraging and warrant the development recom- mcnded." In checking up Thomp- sons report, Mir Finch says:
 "Mr Thompson has in mind some development here which hc has doubt less explained to you, which l ap- prove"
 Preparing Site.
 Tn accord with the reports sub mitted by Messrs. Finch and Thomp- son, the management of the Green Monster Company has force of men at work preparing a site for the per manent camp buildings and for the doublc-comDartment shaft that will be utilized for the development of the ore bodies at depth. These opera tions are being prosecuted on the Brad claim a wedgc-shaped piece of oround that ties to the Revenue, l Cliff, Green Monster, Brookshire and Protector claims, whose orc bodies ! are to be developed by a series of crosscuts and drifts radiating from the main working shaft. The object i've of this shaft is a depth of 1000 feet. It is to be equipped with cleo trically driven machinery which will include a l2-drill compressor and a hoist having lifting capacity from d ! depth of 1000 feet. A contract for | electric power has been entered into with the Arizona Power Co. The vari- ous machinery units have been or dcred, and the management expects | to have them installed and in opera ton not later than August lst.
 Will Increase Force.
 Thereafter, as soon as IS practica- | ble, the present force of 20 mincFs will be considerably increased with | the object of sinking the shaft to the permanent sulphide ore area as rap idly as is compatible with safe and economical mining work. Stations will be cut at l00-foot intervals as the | shaft is lowered, fo- the purpose Of ascertaining the general average grade |, of the oxidized ore The real devel- | opment of the property will, however, begin in the sulphidc ore orca at an approximate depth of 1000 feet. At the greater depth the ledge crossing | the Revenue claim will be explored | This ledge outcrops for a length of 2.000 feet and has a mean width of | % feet. A tunnel for experimental purposes-100 feet long-has tapped this ledge at a depth of 1 10 feet with i gratifying results.
 Open Pay Gold Ore
 The pay gold orc opened at nom- | inal depth in three tunnels on the 1 Cliff claim will also be opened at . depth by means of the main shaft. ! The Trail tunnel on the Cliff has q | length of 600 feet and is connected | with the upper tunnel by an uprai5e of l40 feet and with the lower or Gulch tunnel by winzc of 200 feet ! These workings carry gold ore hay ing an average value of SIS per ton | ,.,J +rara nf rnDDor Gold '
