Dec 18, 2019 Test work results have indicated that the CDG ore is amenable to heap leaching for the recovery of gold, silver and copper. CDG ore is estimated to contain an average of 0.09% copper based on the mine plan used for the PFS. A portion of this copper is cyanide soluble and is expected to be extracted in the heap leach circuit.

concentration, and heap-leaching of copper using commercially available mining cost estimating software and mineral processing models of Camm (1991). This paper assesses two methods of cost-modeling for open-pit mining and heap-leaching of copper ores with copper recovery by solvent-extraction and electrowinning (SX/EW).
The Feasibility Study will be based on the PEA and will include a large open-pit operation, a concentrator to recover copper, gold, silver and molybdenum minerals, and a solid waste facility to store mine waste rock and mill tailings. The project will also include a heap leach facility to recover gold, silver, and copper from oxide ore.
