27 U .S. Arm y Corps of Engineer s and Bureau of Land Management Project: Elder Creek Mine, Nevada, USA. Scope: The USACE identified the Elder Creek mine in Nevada as a site requiring extra funding for additional assessment prior to reclamation. Outcome: The USACE and BLM proposed to stabilise and reclaim portions of the waste rock dumps, spent heap, ponds, and other disturbance. SRK evaluated the potential environmental impacts, prepared the engineering designs, and oversaw the construction efforts. W e prioritised the reclamation efforts to use available funding to reclaim components that presented the greatest risk of degrading the environment. BHP Billiton Project: San Manuel mine and plant sites, Arizona, USA. Scope: Development and implementation of closure plans for the former underground block cave copper mine, surface and in-situ leach operations and milling and smelting facility . Outcome: Developed strategic closure strategies for the 1 0,000 - acre facility , which included 4,000 acres of tailing impoundments, 400 acres of industrial area and 300 acres of mining area. Prepared the various environmental permit applications and obtained the necessary approvals for closure. Completed the engineering design for the final closure plan and monitored implementation. Deloit te T ouc he and Y ukon Go vernment Project: Faro mine complex, Y ukon T erritory , Canada. Scope: Development of a closure and remediation plan for the mine complex. Outcome: The Faro mine was the largest operation in the Y ukon and its closure plan required the agreement of two governments and three First Nations. W e led the assessment of closure options, and helped to find a plan that was endorsed by all parties. During the multi-year assessment process, we also provided engineering for ongoing care, maintenance and remediation projects. Depar tment of Indian Nor thern Af fair s Project: Giant Mine, Northwest T erritories, Canada. Scope: Processing of arsenopyrite ore generated 230,000 tonnes of arsenic dust that was stored underground when the mine was abandoned in 1999. Outcome: SRK assembled a team that was selected as the lead technical advisor . W e led the review of options and the development of a final remediation plan for the arsenic dust, and were then asked to develop a closure plan for the entire site. W e are currently leading a full scale demonstration of the innovative ground freezing technology that was selected for stabilising the arsenic dust.
