Cortez Hills Data
Cortez Hills Information
General 2015-05-10The Cortez Pipeline property is 11 kilometres northwest and the Cortez Pediment property (which includes the Cortez Hills deposit) is 4 kilometres southeast of the original Cortez milling complex. The Pipeline and South Pipeline deposits are mined by conventional open-pit methods. The Cortez property covers approximately 2,800 square kilometres on one of the world's most highly prospective mineral trends. Cortez employs three different metallurgical processes to recover gold. Lower-grade oxide ore is heap leached, while higher-grade non-refractory ore is treated in a conventional mill using cyanidation and a carbon-in-leach (CIL) process. Heap leached ore is hauled directly to leach pads for gold recovery. Carbonaceous mill ore is mined intermittently during the mining of the Pipeline/South Pipeline deposits. The Cortez Hills underground mine is accessed by twin declines portaled in the old Cortez Gold F canyon pit. The breccia ore zone employs underhand cut and fill mining methods with cemented rock fill as backfill. The top cut of the underground mine will eventually be the bottom bench of the Cortez Hills open pit. With 2011 production of 1.42 million ounces at total cash costs of $245 per ounce1, Cortez is one of the world's largest and lowest cost gold mines, and the property also has excellent upside exploration potential. Production in 2012 is anticipated to be 1.20-1.25 million ounces at total cash costs of $300-$350 per ounce1, reflecting a higher proportion of underground ounces and lower open pit grades as part of planned mine sequencing. Proven and probable mineral reserves at Cortez as of December 31, 2011 are 14.5 million ounces of gold.
