Subject: Canadian Rockhound
An area that may be of interest to you is a place called The Ovens located on the coast near Lunenburg. They are a series of sea caves which were enlarged for gold extraction in the mid-19th century. As an interesting aside the area is owned by the family of the late folk singer Harry Chapin.

I suppose this is more of a geological interest than specifically rockhounding. It is well worth the visit. Plus its proximity to Lunenburg (a wonderful small port) is another bonus. The website for The Ovens I ran across this website that includes Mineral Collecting Localities in Nova Scotia. Access to a large PDF file with geological history of the Ovens.

Hope this is helpful,
