Goethite after Pyrite with Calcite

Unknown Owner
Interesting specimen from this famous mining district, a cluster of what were once cubic pyrite crystals to .5 cm across, these now replaced by goethite, and set along one edge of matrix covered by small sparkling crystals of calcite. In great condition.
