The technical development and operational commencement stage of the Beverley in situ leach uranium mining project are herein discussed from the viewpoint of hydrogeological factors. The author summarises the uranium deposit's hydrogeological setting and its bearing on the aquifer investigative programme and leaching process trial design, and then describes in turn the basis for the Commonwealth Government's acceptance of the mine design being in compliance with all necessary safety and control requirements, which has then allowed it to grant environmental clearance for the issue of mining leases, the reasons for the forecast absence of potential environmental impacts from the mining activity and waste disposal methods on the region's groundwater regime, and lastly the scope and intent of environmental management and monitoring strategies that have been put in place by the licensee, in conjunction with the responsible authorities, to protect local groundwater systems.
