This is a very good sized specimen, for the species, which has been only found at two locations, just a few miles apart in West Aust, no where else. Nothing has been retrieved at either location since the original finds, and will never be because of the subsequent work and abandonment of the mines. Today this material is unobtainable, we were fortunate to have obtained some years ago when the Armstrong mine discovery was made, of which we put a couple aside for later years.
