FINAL COUNTY.

LUlE mine consist of a series of tunnel levels, running parallel and connected from She sides by cross-cuts and from the tops and bottoms by winZes, thus securing perfect ventilation. There are at least three thousand five hundred feet of these, but not a single stope, except at one point where the vein matter was decomposed and could not support the ore, which, dislodged by its own weight, dropped down n q great mass. But notwlthst inding no stoping has been done 1t is remarkable fact that over 5000 tons of ore have been extracted, giving an average of nearly one ton to each loot of the workings. In passing through the workings We found but fifty feet or work in barren ground. In all other portions the sides, roofs and floors of the drifts, cross-cuts and levels show ore either in continuous shoots, kidneys or large chambers. From the lowest level, l75 feet, two winzes are sinking and one of them appears to be penetrating a mammoth ore jOdy. It has been sunk to a depth of fifty feet, having an inclination of about 40 de- grees, to the southeast, and follows ore all the way down. At the bottom . cross-cut has been made, 20 feet in an easterly direction, and passes through ore all the way. The other winZe IS down 50 feet ard in ore, but no drifts have been extended from the bottom yet. So far not a stick of timber has been placed m the mine, the vein matter being suf- ficiently compact to stand without sup port. This is due however, to the fact that the mine Is perfectly dry. This Is a great advantage to the mine as timber ing K a large item of expense in mining. Another advantage the property has IS the fact that 1t can be worked to a depth of several hundred feet by means of tunnels, and without doing any dead work" or incurring the expense of erect ing and operating hOisting machinery. There is, in the mine and on the dumps, at least S300,000 worth Of ore in sight. This is by no means an extravagant esti- mate, as there are over 5000 tons of sec ond grade ore on the dumps, giving, by the most careful sRmpling, an average of S40 and over per ton, and, as we stated above. ore ID large quantities have been left standing in all the workings. 240 tons of selected ore have been shipped from the mine and sold in San Francisco,
 
 have received for this ore an average of $50 per ton, amounting ID the aggre- gate to SS4,000.
 The CopperOsity. which lies five miles easterly from the Vekoi and nc the base of a spur of the range m which the lat ter property IS located, as the name in- dicates, IS a copper mine. The vein runs from the mountain across low foothills in a southwesterly course. Two hun- dred and fifty feet from the southwest end line a vertical shaft has been sunk to a depth of % feet. It starts on the vein. but at depth of B feet the latter pitches out of the shaft to the west. A drift has been driven west from the bot tom of the shaft and cuts the vein ten feet from the face of the drift, then passes nine feet through ore into talca- reous matter. Ten feet further on the drift cuts another vein lying parallel with and dipping toward the first veln. The width of this second vein has not been determined yet. It has been pene- tratad a distance of six feet, and the breast of the drift IS still in solid ore. The ore Is principally red oxide, and will smelt beautifully, as 1t carries a AhEkt INANEnAnkt hA AAbA AAL 0AAANhtN-
 The Welshman.-This is an extension of the COpperosity. About forty feet from the northeast end line two shafts of corresponding depth have been sunk and connected at a depth of about forty feet by & 30-foOt drift, in which there Is 24 feet of ore, of the character and ap. parently the same grade as that of the Copperosity The shafts and drifts are all in vein matter, snd neither the hang ing nor the foot wall has been reached SO the ledge at thls point Is over 30 feet wide. There are other small openings on the claim, all of which show the ledge in place and full of ore. The ledge upon which the Welshman and Copperosity are located lies in lime, and shis fact adds much to their market value, as most copper experts regard line as the best formation for copper.
