Fire River Gold Announces Update on Tailings Preliminary Economic Assessment, Nixon Fork Gold Mine, Alaska
The company provided an update regarding the progress of work on the Preliminary Economic Assessment (PEA) for the tailings re-processing option at the Nixon Fork Mine.
The previous operator of the mine designed and partially installed a 250 tpd CIL circuit for the purpose of recovering gold from the impounded tails and increasing gold recovery from ongoing mining operations
The Company’s original plan was to complete construction according to the last operator’s design with only minor modifications and enhancements as required. This Base Case has no provision for recycling cyanide in the circuit – all leaching solution is passed to a cyanide destruct circuit at the end of the process. It has become obvious through the course of work on the PEA that economics of the Base Case will be significantly enhanced by recycling the cyanide solution, reducing reagent consumption and the associated purchase and transportation costs.
