The vein has an average width of 7 feet, and runs north 35° west, with a dip of 12° to the southwest. The claim is 1,500 by 600 feet and embraces two promising ledges. Three places have been opened at the eastern extremity of the claim at intervals of about 50 feet. The first two are in open cuts, in which the scalping process was employed and gems were taken from broken-ledge matter and soil. The principal working, however, consists of a tunnel 18 feet long, from which a stope following the pay shoot for -45 feet has been run. Both foot and hanging walls are of a gray decomposed diorite, in which the feldspar has been much altered, with some quartz and biotite. The ledge shows first some 3 feet of coarse, poorly crystallized pegmatite, stained in some places with iron and manganese. Man}' black tourmaline crystals with terminals pointing directly toward the pockets were observed, somewhat altered to quartz and muscovite. Below the pegmatite is a stratum from 1 to 6 inches thick of a grayish or whitish decomposed orthoclase, with disseminated crystals of muscovite having a pinkish and lavender tinge on the outer edges (probably a lcpidolite border, as sometimes noted elsewhere). In this stratum, coated with albite and clajT, pink beryls are found, generally solitary in a pocket, with two or three large blackish-green tourmalines. Quartz crystals were observed on both the top and bottom of this stratum, but not in the pockets with the beryls. It was also noticed that the pink-tinged muscovite was not in contact with the beryl crystals. Contrary to what is usual in ledges of this character, the edges of the pockets do not touch between the upper and lower strata, but continue through the entire working without interruption, although widening and narrowing in places. No other minerals were found existing in the same pocket (or rounded mass of clay and decomposed spar).
Underlying this beryl-bearing stratum is about 18 inches of a soft albite, angular in crystallization, and with numerous holes penetrating the mass. In these cavities minute essonite garnets were seen, also spessartite (?) and hundreds of small black tourmalines, penetrating in every direction. No gems, however, were found among these. This stratum of albite lies -t frozen" to the line rock, which constitutes the base of the ledge. The line rock is coarse and shows less interlineations than at any other mine observed in this vicinity. In places large portions of graphic granite occur, embedded in the upper stratum of ordinary pegmatite. In this graphic granite are small cavities containing steatite and montmorillonite, with lithia mica occurring at intervals. Minute whitish crystals were found in these talcs which appeared to be topaz, although too small for identification. In some places, also, where quartz crystals were found disseminated crystals, of pink muscovite occur, embedded and penetrating. Giant powder was used exclusively.
