This mine, old and little known, has nevertheless produced this unusual and rare combination of blue-green, connellite, a sulfate; and olive green, olivenite, an arsenate. These two species are beautifully crystallized in a quartz vug along with gemmy, quartz crystals, to .5 cm in length. These specimens are thought to be from the late 1700's, I am told; although not given a proper species name til the 1850s. In any case, its old and attractive and very, very rare!
