Here is an excerpt from a report I have of the original installation of this mill by William Resources, this was written by David Morgan in 1999.

"The processing plant at Velardeña is a conventional, modern, cyanide mill, originally constructed in 1992 for a mine in Canada and designed to treat oxide ore. William bought it in 1996 and re-erected it at Velardeña. The facilities appear in good mechanical condition and comprise a crushing and screening plant, ball mill, leaching tanks, a counter current decantation circuit and a Merrill-Crowe precipitation plant. The mill can currently treat over 600 tpd, and could be readily expanded to 1200 tpd, mainly by adding further grinding capacity"
