  REPROCESSING AND TAILINGS REDUCTION

  ''ant heaps'', old tailings which were processed 100 years ago by gold mining companies. "These ''ant heaps'' had more gold in them than most current day gold mines. Because the technology at the time was not very sophistied, they could not recover as much as they can now. Most of those historic tailings have now been reprocessed."
