(2) Cut-off is based on NSR, Oxide = $29.03/t, Supergene = $26.57/t, Primary = $26.68/t, cut-off grade values shown above are approximate and may be affected by other metal values in the deposit.
Mine life extended to 13 years and waste-to-ore strip ratio increases slightly to 4.2:1.
Bisha 13 year undiscounted cash flow now totals $2,162,000,000 using $1,200/oz gold, $24/oz silver, $3.30/lb copper and $1.00/lb zinc, all on an after-tax, after expansion capex basis.
