“Very rich masses of black cesarolite are throughout this 4.7 x 3.5 x 2.5 cm matrix. Quite good for this species! This is an old locality that has not been worked since the 1950's. I visited here in 1999 and despite the large mountain of mine dumps, did not see any evidence of mineralization. Ex Peter Gillis collection.”
