Report: Solar-Pearl Both Roby and others (1960) and Ruppel (1963) provide descriptions of these mines. The Solar workings consist of one caved shaft about 140 feet deep with two levels totaling 500 feet along a N70-80E steeply north dipping vein with quartz, pyrite, tourmaline galena, tetrahedrite, arsenopyrite, and chalcopyrite. The early ores mined reportedly contained up to 3 oz gold and 300 oz silver per ton, but production since 1902 has been 251 tons of ore from which 166 oz gold, 10,048 oz silver, 245 lbs copper, and 6,142 lbs of lead were recovered. Our own select sample (JJSO-1) of vein material ran .058 oz/ton gold, 3.32 oz/ton silver, 0.035% copper, 0.51% lead, and 0.068% zinc. The dump is comprised of quartz monzonite, about 10% of which has been altered to a quartz-sericite-pyrite rock. A caved adit trending N85W with a dump of unaltered vegetated quartz monzonite is also present. The Pearl explores the same vein well to the west with one short, caved, flooded shaft. Mineralogy of the vein is similar to that of the Solar. Both sites are on Deerlodge National Forest land.
