Wulfenites as well as Mimetite specimens were mined about 2 years ago at the Ojuela mine, following a prolonged draught that lowered the water table low enough to allow mining in these previously flooded zones. Since then there have been production issues due to re-flooding, as well as cartel activity in the area. Even when they were producing, this was a fine example of the wulfenites found at the time. They are forming on top of green Mimetite (most obvious in third pic). The crystals appear a little more orangy in incandescent light, but are bright and glassy regardless. It's in great condition overall with a small touch of damage on the lower bottom right side (not visible when displayed). I can include a stand if requested.
