“A rich mass of Chalcocite on quartz with minor malachite, from Pine Mountain, Iron Springs, Adams Co., Pennsylvania. From a one time find by Joseph A. Dague in the early 2000's. Some native silver was directly associated with the chalcocite from this occurrence, silver being a fairly rare species for Pennsylvania. Specimen size: 7.5 x 4.5 x 3.5 cm. From the PA Annex of my personal collection, acquired in 2005.”
