There has been intermittent renewed private interest in the recycling of mine tailings to remove Barite for use in engineering services related to offshore drilling. A reorganized version of the Barite recycling operation first attempted by Asarco in the early 1980s, prepared and tested by another group in the late 1990s, did operate under Pennecon in 2009 and intermittently under another partnership in the 2010s. The tailings ponds near the Lucky Strike mine site contain millions of tons of material that is 30% barite.
