Mineralization is manganese ores, probably mixed pyrolusite and psilomelane, in a flat-lying lens, or large pod, in Tertiary sedimentary bed above a basalt flow. Local rocks include Middle Miocene to Oligocene volcanic rocks.
Workings include an open pit. Production was over 900 long tons of 22% Mn in 1953-1954.
