operations on this property are likely to be very extensive in the near future a brief description may be acceptable to the general public.
 The ledge lies on the east flank Of black pyramidal mount about three and one-half miles northeast of the town of Goldfeld and six miles from the Salt river. The general trend of the lode is northerly and southerly, and 1t is not again exposed to any extent un- til 1t enters Superstition mountain about three miles east of the point Of the mountain, being covered much of the way by a red ferruginous sandrock partially auriferous, aud the general rock usually found in the basin; north erly it dips under calcitic bluffs and sandrock, not again being exposed on the south side of the river.
 There are a number of shafts on this property. Shaft A, about 15 feet in depth. sunk on stringer from the main vein, gave very satisfactory re- suits near the surface and for some distance down. The Truman shaft, down a distance of 40 feet, lies little west of the first mentioned; this con- tains fairly defined vein with quartz ite and porphyry in the wall rock, the ore extracted from this shaft was richv CT at the surface In free gold than it was in the bottom.
 In an incline now down 20 feet, which lies north of the first mentioned shafts, the vein has been reached and a peculiar feature eff the ore found is that it contains copper In silico-car bonated condition. This seems to have been the agency by which the gold in the magniferous iron (which usually con- tains small amount of copper) was rendered free. This cuprous rock con- tains gold which is free, brilliant and of high degree of purity. it is found enclosed in pockets in the general vein stuff. This leads to the supposition that the cuprous character of ore higher up has been eradicated or 1 leached out by percolating waters in | the seams of the vein stuff.
 l An air connection is to be made by means of this incline with the main workings of the mine, these consist of an open cut sunk on an incline, the south side being the footwall of the ledge. This extends for some twenty. five feet in northerly direction; fall of ground has rendered it at present un- workable. A shaft also on an incline short distance north of this cut, which is over 60 feet in depth forms the entrance to the lower working of the mine. At present this shaft is trouble some on account of the foulness of the air. Pure air will, however, be secured on completion of the air shaft mention ed above. The ledge in the lower workings has been stripped 25 feet northerly and 15 feet southerly and the exposed vein consists of very rich ore i; this will be stopped and the owners ex- ! pect to keep sufficient ore stripped to run continuously; rock assaying from $200 to $500 per ton is frequently met with in these workings.
 A perpendicular shaft some 80 feet in | depth and having a connection with q tunnel, has been sunk on high DOT phyry dyke which caps the lode. This dyke has value Of $3 to $7 per ton and is about 15 feet wide at the surface. 1 The lode below has been ross-cut to 8 width of 50 feet and carries gold throughout its entire width. The dump from these workings containing over 600 tons of rock has an average gold value of $4 ton. Granite when found in the lode is generally auriferous. Ore from veins in this lode has yielded ex- cellent results in an arastra.
 Tho earlier works consist of numer ous prospect pits and shaft now down so feet sunk on ledge feet in width at the outcrop afterwards contracting to width of feet; pay streaks in this vein yielded an average of $50 per ton i; richer rock is expected below water level; there are about 200 tons of ore on the dumps averaging $10 ton.
 A tunnel can be run gaining a depth of over 100 feet below the present workings which would greatly facili- tate the extraction of ore. Placer gold is found here in several of the gulches.
