New Chance property.

The New Chance property is located about 4 miles southeast of Union Pass, about a mile south of the Monarch mine, on the upper west slope of the range near the crest, between 3,600 and 3,900 feet in elevation. It was discovered about 1900 and is owned by Mike Redman, of Kingman. The developments are slight.

The general country rock is the pre-Cambrian granite, cut by a sheeting that dips steeply to the north.

The deposits occur in a lode contained in granite, rhyolite, and andesite and are reported to range from 20 to 30 feet in width. The strike is about N. 18° W. To the south of the gulch the lode stands about vertical, but to the north it dips steeply to the west. It is exposed for a horizontal distance of nearly half a mile and through a vertical range of 200 or more feet. The croppings, which are in part prominent, are dark iron and manganese stained quartz and silicified rock, which is chiefly rhyolite.

The ore is mostly contained in a vein about 2 feet thick, composed of quartz, calcitic brecciated rhyolite and andesite, and green fluorite. The ore streak in this vein, as shown in the shaft on the upper or south end of the property, where the vein is in rhyolite, with a greenish porphyritic rock similar to the andesite of the Vivian close by, is 8 to 10 inches in width, and is reported to average about $64 in gold and 2 ounces of silver to the ton. The values are found mostly in the quartz-adularia portion of the vein, and are said to be best where associated with the fluorspar.

To the north of the gulch the ore, here also contained in a quartz-spar gangue, is fairly well developed along the rhyolite-granite contact, and at a point where the rhyolite is faulted off the ore continues for a distance of 200 feet in an extension of the fissure into the granite.
