specimen number:
2063173

location:
Erupcion Mine, Los Lamentos, Chihuahua, Mexico

description:
Classic old Mexican specimen with crystals of blocky wulfenite measuring to 1.0 cm on edge across the top of matrix. The entire grouping of wulfenite is coated with small micro needlelike brown crystals of vanadinite. In good condition. The specimen comes with a previous label from the collection of Ray DeMark.

The Erupcion Mine, located in the Los Lamentos mountains of Chihuahua, Mexico, was discovered and opened around 1920, with primary commercial operations winding down by the late 20th century though intermittent specimen recovery occurred later. Geologically, the mine consists of replacement deposits formed within Cretaceous limestone, where hydrothermal activity and subsequent oxidation led to rich secondary mineral zones. It is globally famous for producing world-class wulfenite specimens, characterized by thick, tabular, highly lustrous crystals with vibrant orange, yellow, and brown hues.
