The mine has been worked to a depth of 660 feet by numerous and extensive levels. There are two parallel veins or lodes, known as the East and West, about 28 feet apart. The strike is 1ST.E. and the dip 45° K.\Y. At the 60-foot level they come together, making 20 feet in width: at the 160-foot level the distance between the veins again widens to 32 feet, and the dip approaches the vertical. At the 200-foot level the width of the west lode is 10 to 15 feet. This mine was discovered in 1838; it was last worked 12 years ago.
The Silver Valley mine is situated 5 miles northeast of the Silver Hill. The character of the country and the ore are similar to those at Silver Hill. The strike of the lode is jST.E. with a dip of 45' X.\V. The hanging is siliceous argillaceous schist, and the foot-wall, a hard hornstone (devitrined quartz-porphyry). The outcrop is a barren milky quartz, 20 feet wide; the sulphurets appear at a depth of 60 feet. The mine has been opened to a depth of 120 feet. The lode is from 5 to 12 feet in width and consists of alternate bands of slate, quartz and sulphurets, the latter seams being from 3 to 18 inches thick. A 20-stamp mill stands on the property.
