The Romans mined the opencast ore body as a source of iron, for about 300 years, until the third century AD. With the technology at their disposal, they apparently did not discover that the siderite/ankerite gossans they mined as iron ore were weathered caps of auriferous pyrite and arsenopyrite. The Romans would have loved the gold.
