GLA uses Enhanced Metal Recovery (EMR) to help mining clients access previously unrecoverable gold, silver, and copper. EMR has resulted in recovery of tens of thousands of additional ounces of ore for our mining clients, adding tens of millions of dollars right to their bottom lines.
EMR is a heap leach injection process that involves installation of steel-cased wells in heap leach pads with multiple perforated zones throughout the well profile. GLA uses proprietary tooling to isolate the respective zones and inject solution. The injection flushes out previously dissolved metals and creates new pathways to ore that had not been previously exposed to solution. EMR thereby accelerates the recovery of target metals and recovers metals that were unrecoverable utilizing traditional surface application leaching. Project revenue, as additional ounces recovered, is generated within days of the first injection of solution.
GLA has performed heap leach injection projects at seven mines in three countries since 2015, making GLA the most experienced heap leach injection company currently operating internationally. GLA’s proprietary heap leach injection technology has a proven track record in various parts of the world.
