Historic Gold Mine Tailings FAQ What are gold mine tailings? Tailings are a by product of a gold mining process that was common in the late 1800s and early 1900s. Gold bearing rocks that also contain arsenic were crushed and spread over liquid mercury to remove the gold. The mercury was then evaporated, leaving the gold.

Arsenic and Gold Mine Tailings FAQ What is arsenic? Arsenic is a natural element that can be found distributed throughout the Earths crust. It is found in arsenopyrite, the same rock in which gold is often embedded. Many areas of Nova Scotia have elevated arsenic levels, not just the gold mine tailing sites.
Tailings are materials produced from mining such as milled rock and effluents. In many cases, massive quantities of these materials, regarded as waste, are left from previous operations.
