Nova Scotia Mines and Minerals ~ Historical Timeline, 1604-1992

The following timeline has been adapted from the 'Chronology of Minerals Development in Canada,' compiled in 1998 by the Canadian Institute of Mining, Metallurgy and Petroleum, and available online as part of the Natural Resources Canada Website. Information additional to the Institute's original listing has been added to the timeline presented below — which although it doesn’t include everything relating to the history of mining activity in Nova Scotia, is nevertheless a useful tool for tracing the more significant events.
