Description: The first significant occurrence of aragonite in the Sterling mine occurred in large pockets in erose ore adjacent to the "mud zone" in the 1040 and 1080 stopes, between the 430' and 500' levels (witnessed by C. Lemanski, Jr. - 1965). The pockets were large enough for a person to et in, but not very deep. Miners collected what they could on the shifts that encountered the pockets and destroyed what was left so that the cross-shift (evening shift) could not collec any of the best material. This is why there are many busted crystal specimens best only for UV display. Reference: [Jenkins & Misiur: Min.
