Description

Very rarely does native copper turn up at the Little Deer Park and this is a good example of the occurrence. The copper rests on some excellent natrolite crystals with some natural staining. There is also considerable alteration of the copper to produce secondary crystaline copper minerals.I have been collecting regularly at the locality for almost 20 years and could count the number of native copper specimens I have found on one hand.
