Concentrates from the gravity circuit were initially combined and sold with a lead-copper concentrate. In 1991 production of this concentrate ceased in favour of a higher grade, low lead, lower volume, copper concentrate. From this point, gravity concentrates were stockpiled awaiting the construction of a facility to produce gold dare on site.
