Tailings are what remain after desired recoverable minerals are removed from ore. Tailings at the Stibnite Gold Project will be comprised of the finely ground rock materials remaining after the minerals stibnite (hosting antimony and some silver) and pyrite (hosting the gold and some silver) and free gold, are extracted and concentrated in the ore processing facility (see Section 10). Since all sulfide minerals (primarily stibnite and pyrite) at the Project contain metal that has economic value, they will be recovered as much as practicable, thus reducing sulfide minerals to a very low level, thereby generating low sulfide content tailings. See Section 10.1.10 for a discussion of tailings chemistry.
