Description: Copper Chimney Rock quarry, Bound Brook, New Jersey, USA 8.5X6.8 cm The Chimney Rock quarry was on the site of an old copper mine. A copper chunk around 90 lbs. jammed the crusher during the quarrying operation. I believe it is still in the Rutgers collection. During my collecting there, I found mainly calcites, analcimes, traces of copper minerals and a prehnite or two.
