Show 51 in that region. The timber is chiefly of pinon and juniper 5 its quantity is small, bat sufficient. The water is very good and pure, and there is enough in the vicinity to run another 30- stamp mill. The Surprise Valley Company owns a large spring near the mines, and the Sunrise Oompauy has a well 40 feet in depth. There are about 500 inhabitants in the district, besides some Pah- Ute Indians. * CHARLOTTE DISTRICT, CALIFORNIA. Examined by Lieut 0. W. Whipple, July 20,1875. This district is at the head of the Tejongo Creek, near the summit of the San Gabriel Mountains. It is about 40 miles from Los Angeles, its principal source of supply, and 32 miles from San Fernando, which is the most convenient post- office and railway- station. It is now reached by a difficult trail up the Tejongo, over which supplies are transported on burros. An easier trail, by way of the Arroyo Seco, is believed to be practicable and will be attempted. It was discovered in 1870 by Mexican herders. Since that time it has been worked at intervals by these people and by the proprietors of the Harding Mine. No geological examination has been made, but the main vein has been followed a distance of 4 miles in a southeast direction. The rock of the walls and in the vicinity is almost entirely quartz, but farther down the stream it is a coarse, friable granite. No silver has yet been found. The vein is of gold- bearing quartz, in which some iron pyrites occur. In places this is hard and compact, and again it is soft and earthy. The mountain range has here a general east and west trend, with spurs projecting to the south, which are traversed by the several veins. The Charlotte and Las Animas Mines are upon the same vein. The former,* upon which work is now iu progress, has been sunk to a depth of tl feet. The main vein is about 3 feet wide, and is crossed diagonally by another, 18 inches in width, with an inclination of 30°. The Poyo-rena, the Union, and Mejicana are on a second vein. Work upon the Poyorena is about to be resumed. Its shaft has reached a depth of 30 feet. The vein is 3 feet thick, extending without fault from surface to bottom. The Union is at a depth of 40 feet. The Pacific, on a third vein, was not visited. The Harding Mine has reached a depth of 40 feet The quality of ore seems to improve with increase of depth. In places it is very rich, the managers of the Charlotte Mining Company claiming that these culled pieces will assay $ 300 per ton. This company has completed two arrastras, with which they expect to work two tons of ore per day. It is anticipated that it will cost $ 30 per ton to extract and work the ore. The district is peopled by about fifty miners and prospectors. The supply of water in summer is scanty, proceeding from the springs at the heads of the valleys. On the north exposure of the mountains, near their summit, there is good pine timber. Bear and deer are plenty. The principal impediment to the development of this district is its inconvenience of access. With a new road, which would allow the introduction of improved machinery, it might be very profitably worked. SAN EMIDIO DISTRICT, CALIFORNIA. Examined by Douglas A. Joy, November 9, 1875. This district is in the San Emidio Mountains, at the head of Plato Creek, on the divide between this stream and the San Emigdio Canon. * Tbia mine baa since been abandoned.- ED. |
