EMI COWIT BODY GROWS LARGER Winze Being Sunk on Vein Shows Mineral Going Down Strong. Th ore. body ncountreil ome tim o on fhfl Ernma Coppr property in th Littl Cottonwood dlatrV t ha been proved for seventy feet along Irs trlke and for ntnty feet In height, according to the management. Another carload wai hhipped last week from the breccia ted vein and in the winze that Is being sunk on this vein the Indication are that the ore body la going down strong. In the No. 2 east drift work has been somewhat retarded during the past week owing to the non-arrival of timber required re-quired for the ohute In No. 2 raise, just completed. The drift to the east of the lead stope Is being advanced, and has proved with absolute certainty certain geological features of the utmost Importance. Impor-tance. It hss shown with remarkable clearness how the faulting movement, has out the limestone beds, and how the ore that haa been found along this fault plane is a drag from an ore body higher up. It demonstrates that by following along this fault plane a continuation of the faulted ore body should he met with. The proximity and general direction of the working In the EJmma Copper to the old EJmma ore body gives rise to the strongest possible belief that further exploration ex-ploration will lend to finding of the continuation con-tinuation of the old Emma ore body that waa cut off hv a fault, which, according to those familiar with the district, has every resemblance to the fault met with In the Emma Copper mine. A good deal of work was done In the old Emma ground In trying to find the continuation of this ore. but without success. The probable cause of the failure is undoubtedly undoubt-edly due to the fact that all the exploration explora-tion was done below the fault plane, whereas the continuation should have been looked for on the top side of the fault plane. All the geological evidence Jtoee to show that the faulting movement s normal and that the continuation of the dislocated ore body should be looked for on the side which would lie above, the fault plane. The work now being prosecuted In the Emma Copper nhould demonstrate this as a certainty within the next few weeka. The old Emma ore body contained the richest ore ever produced In the Alta camp. Not only did It carry high values In lead and silver, but also a fair amount of gold. The production from the mine during its life was on euch a scale as to cause the property, of comparatively few n.cres In area, to be valued In the "London market at more than $10,000,000. The suspension of ore extraction In the old Emma was entirely due to the cutting cut-ting off of the ore by the fault, and subsequent sub-sequent to that time several hundred thousand dollars Is reported to have been spent In the endeavor to find the faulted portion.
