Iroquois
Mine was one of few recent mines to be opened (1949) for
exploration purposes. They hit on a seam of datolites andt dumped
them on the piles. Most of the datolites found there are white,
and some came with gray, and orange to pink dots. The mine dump
had been
bulldozed only few times I advise against bringing any metal
detectors
to the mine dumps for the prehnite rocks are quite rich in bits of
copper.
