Mine Planning. MMC selected an open pit/heap leach mining method as the basis of the analysis and evaluation for the PEA. A production schedule of the leachable material averaging 0.41 g/T gold over life of mine was the result of selecting a gold price pit design of $650/oz.
Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re separates them after their division from other earth materials.
