Show 52 It was discovered in 1871, since which time it has been continuously prospected. It is connected by trail with the San Emigdio Canon, and thence by wagon- road with Bakersfield, 45 miles distant, which is the most convenient post- office and railway station. The outcropping follow the top of the ridge, which has a general east and west trend. They have been traced more than 3 miles, but the exact area of the district is uncertain. The strike of the vein is due north, and its dip, according to the best estimate, is 90°, vertical. The country- rock is massive granite. The dependence of the quality of the vein upon the local character of the country- rock has not been investigated. The wall- rock is granite. Its dip is 90°. Tertiary sandstones overlie this rock about 4 miles down the ridge. The character of the vein has not yet been determined. None of the ore extracted up to date has been worked. It is proposed to smelt it in a reverberatory furnace to crude antimony, ( pan sulphuret.) The ore extracted assays 75 per cent, of sulphuret. The ore is nearly pure sulphuret of antimony, with some silver and iron. Some quartz is irregularly intermixed, aud also a little feldspar. The greater part of the ore is colored red on the outside by oxide of iron, and, until broken, does not show the characteristic black metallic appearance. It is hard, and but little decomposed. The district has been worked in but one place, and not extensively there. The water level is not yet reached. Several tunnels, from 15 to 45 feet in length, have been run, but nothing more has been done. This mine is supposed to have been worked in former times by the Spaniards, as there are indications of previous labors here, and in the adjacent valley of Plato Creek an old furnace has been recently discovered. The vein- matter should be followed in ruuuiug shafts and drifts. On an average, eight tons of ore can be stoped per diem by one man. Water is abundant in the neighboring canons. The country roads are good. On the surrounding mountain slopes there is good pasturage and excellent pine timber. Deer, grouse, and mountaiusheep abound in the mountains, and antelope on the plains. GREEN MOUNTAIN DISTRICT, CALIFORNIA. Examined by Douglas A. Joy, October 6, 1875. The Bright Star Mine is the principal one in this district. It is situated at an elevation of about 8,000 feet, within a mile of the summit of the Pah- Ute Mountains, which lie in a clump between the Keru River and Kelso Valley, about 15 miles south of Kernville. The district was discovered in April, 1866, by a Mr. Rains. It was organized in the same year, and has been worked continuously since that time. Its most convenient post- office is Havilah, with which it is connected by trail. The nearest railway station is Caliente, which, by wagon- road, is 85 miles distant. The country roads are good, though steep. Cost of freight from Caliente is 3£ cents per pound. The exact area of this district is not known, as no geological surveys have been made. The superintendent of the Bright Star Mine claims to have traced the vein- wall a distance of 1£ miles, but admits that the substance of the vein is not entirely quartz. Its geuerai trend ia northeast and southwest. There is no other mining ledge in the immediate vicinity. |
