Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Mine Description

The Mammoth property of eight claims, held by Hugh bard and associates, is 8 1/2 miles by road north of Hillside and within 3/4 mile of the Santa Maria River.

This deposit, which is reported to be on school land, Was discovered many years ago. Since 1931, it has produced several cars of ore.

Here, a moderately hilly pediment is floored by extensively jointed granite. The present shaft, which is 175 feet deep, was sunk on a narrow southward-dipping fault zone that showed a little iron oxide and copper stain. Between the 80- and 100 foot levels, a short drift to the east encountered an ore shoot that strikes S. 70° W., dips NW., and is about 20 feet long by 2 to 2 1/2 feet thick. This vein material consists of coarse-grained milky quartz, pale-yellowish calcite, and fine-grained purple fluorite. Small masses and disseminations of yellowish pyrite are present in the quartz. In places, the pyrite is oxidized to limonite. The Wall rock shows strong sericitization. According to Mr. Hubbard, the ore mined from this shoot in January, 1934, averaged about 0.4 per cent of copper, 0.51 ounces of gold, and 2 to 3 ounces of silver per ton. Trucking to Hillside cost $1.50 per ton.
