Gold is recovered in a Carbon in Pulp (CIP) technology process plant. Yearly average production is about 4500kg of gold-silver doré (fine gold production is in the order of 3,500kg). The average fitness is 78% for gold and 21% for silver; the remaining 1% accounts for other elements of no commercial interest. The gold doré bars are shipped to Argor Heraus refinery in Switzerland; the gold is then refined and sold to ARGOR-HERAEUS SA in Mendrisio Switzerland.
