producers with a historic resource of 27Mt at 4.3% Cu, 10% Pb, 3.5% Zn and 95g/t Ag 2. A compilation of previous drill data and mining plans at Khusib Springs shows that remnant copper ore exists on the margins of mined stopes. The unmined ore is in the footwall between Levels 2 and Level 3 at a depth of ~50m and could easily be mined by open pit.
