purchase 45O feet of development are shown. Considering the warm weather incidental to that section at this time of the year, extensive ex- pIoitatiOn is necessarily delayed, and until cooler weather comes the pres ent methods of operating will pre- vail.
 Interest attaches to the discovery of this new copper field from the fact that it suddenly comes into prominence from the limited work it formerly received from its loeators, and its possibilities since work has been given by its new owners.
 Surface examination of the belt shows an interesting geological con dition in evidence. The outcrops lie on both sides of an anticlinal fold, thus forming two great veins of min eral zones. These are designated as the north and south veins, and both occupy portions of lower carbonifer- Ous limestone beds ranging from 300 to 1000 feet in thickness. The ore zones occupy portions of the lime stones, along its contact with the underlying precambian schists. The north vein ranges from forty feet to 200 feet in surface width exposure of the characteristic iron gossan of this type of copper deposit, and for length of 5000 feet The south ore zone shows width of from twen- ty feet to 300 feet, throughout a length of 5000 feet. Copper ear bOnates are present throughout the gossan of both of these ore zones.
 The general course of the veins is westerly, with northerly and south erly dips, respectively.
 The overlying country rock is an desitic porphyry, and it is the SCOT ing away of this overlying eruptive rock that has exposed the ore zone outerops as stated. Intrusive dykes of andesite and diabase, having a general northwesterly course, cut the various formations and ore.
 The creation of this company is to1 be considered as of much importance to the mining industry of the field ad- jaeent to Prescott, and the develop ment of the same will accordingly be followed with interest. Identified with this enterprise are men who are prominently associated with the cop per business of the nation, and in addition to that fact all of them are interested in the famous mines of the lake regions of Michigan, giving the new project more than the ordinary consideration in what the future promises.
