Show sCH ORE SHIPPED BKNIX0HEV1 Last Car Yields Better Than $160 a Ton ; Values Increase In-crease With Depth. Special to The Tribune. COPPER FIELD, Nev. May 11. Smelter returns from the last carload of ore shipped from the Nixon-Nevada show that not only has there been no falling off in the high-grade values of the product of that property, but there has been an actual increase, taking the shipment as a whole. The smelter settlement sheet shows that the ore ran U3.36 per cent copper, (10.80 in gold and $13. 9S in silver to the ton. In other words, one-third of ,the entire weight was in pure copper, while the other two-thirds carried $24.78 in gold and silver to the ton. If the copper content con-tent were to be ignored and, while it is worth 23 cents per pound, 66ii pounds per ton is not likely to be overlooked the value in the precious metals alone would make this a fair grade of shipping ore. The smelter gave $136.25 net per ton for the copper alone. In saving this ore for the shipment, it was sorted Into two grades, and It was announced by the management at the i0tT that the "second-class" ore would jf?ttn 30 per cent copper and the first- class 40 per cent or better. It was intended in-tended by the Nixon-Nevada people that the two lots should be sampled separately, separate-ly, but this was evidently not understood under-stood at the smelter, for both grades were mixed and sampled as one lot- As both lots were nearly equal in size, it is evident that the figures given out when the shipment was made were well within the truth, even though they were bo far out of the ordinary. The continued increase in the values of the ore as depth is gained accompanied, as it is, by a like increase In the width of the veins is the most encouraging feature of the development of the Nixon-Nevada Nixon-Nevada mine. For the first 200 feet in the shaft on the No. 1 vein the ore averaged aver-aged 19.47 per cent copper and $12.13 gold and silver to the ton. In the next 100 feet the copper content increased 5 per cent, with $6 more of gold and sliver to the ton. And tills last shipment, made up from ore from above the drifts on the No. 1 and No. 2 veins above the 300 level, shows a still further increase of S.S9 per cent copper and $6.65 gold and silver to the ton. The No. 4 vein, as well as others opened up in shallow workings, on which comparatively com-paratively little development has been done, is considerably larger than the No. 1 vein on which the shaft was sunk, but the latter is near the base of the hill, and, by sinking on it and crosscutting back to the center of the hill, the other veins which outcrop higher up are cut at much greater depths. The No. 4 vein, it is figured, will be cut at depth of aboufi 900 feet on its dip by the crosscut which goes out from the 300-foot shaft sunk on the No. 1 vein. If, as expected, the No. 4 shows as great an increase in width and values as it did in the upper workings, work-ings, the 800 feet of backs above the level of the crosscut will be sufficient to, provide pro-vide a big tonnage of high-grade ore. The crosscut is going ahead steadily, but has not reached the vein as yet. |
