A former underground Pb-Ag-Cu-Au-Zn (U ?) mine located on 9 claims in North-central (W½) sec. 16, T.21S., R.15E., about ½ mile south of the Black Cap Mine, near the head of a western tributary of Temporal Gulch, at an elevation of about 5,300 feet, near the top of the ridge between Temporal and Squaw Gulches, on private land. Discovered in 1881 by Jim Lewis. Owned at times, or in part, by Jim Lewis (1881-1894); W.H. Barnett & Frank Powers (Happy Jack Mining Co.) (1894-1908); and the Happy Jack Mining & Reduction Co. (1908- ). NOTE: claims: Grand Leader; Mountain View #2; Happy Jack #2; Philadelphia; Wedge; Keystone patented, Pilot patented, View, Clipper Sideline, Happy, and Eclipse. USGS maps incorrectly label a working about 3200 feet S of this site as the Happy Jack Mine.

The country rock is light gray, medium-grained, altered and highly sericitized granitic aplite, or perhaps granite porphyry, and in the mine it is seemingly intruded by a dense olive-green to brown, altered andesite. Both rocks contain a little disseminated pyrite and galena.

Several veins occur on the property. They lie about parallel and dip steeply to the south. The most valuable of the veins, beginning on the south, are the Clipper, Mountain View, and Eclipse. The developments are nearly all on the Mountain View, which is the middle or main vein. It is known from croppings to have an extent of 3,100 feet, ranges from 3 to 6 feet in width, and usually has a foot of soft clayey gouge on each wall. The filling is mostly highly altered rock, with a moderate amount of quartz. The ore occurs mostly in the hanging wall side of the vein.

Mineralization is irregular, lensing quartz-fissure veins containing brecciated and altered wall rock, gouge, and streaks and shoots of sulfides and sulfosalts in Jurassic granite cut by lamprophyre dikes. Possible uranium reported but not confirmed.

Workings include a 30 foot deep shaft (1881). It is also developed by drifts, winzes, and stopes, aggregating 4,000 feet of work. The main, or lower, drift is 950 feet in length and reaches a depth of 400 feet at the face. Worked sporadically from 1881 through 1908. Produced some 150 tons of ore averaging about 34% Pb, 24 oz. Ag/T, 2% Cu and 0.1 oz. Au/T.
