Trekkopje Definitive Feasibility Study

Trekkopje is the site of a green fields project, consisting of a very large, low-grade, shallow uranium resource hosted in calcium carbonate cemented (calcrete) conglomerates.

The project rests in the arid desert region of western Namibia, in southwestern Africa, situated in gently sloping terrain.

Trekkopje will be an open pit operation, primarily using large hydraulic excavators loading haul trucks. With a planned production rate of 100,000t/d of crushed ore and an average stripping ratio of 0.23:1 (waste to ore), the mine life is expected to last approximately 13 years, based on the current resources. The crushing plant will be designed to crush ore at a rate of 7,000t/h to a product size of 100% passing 38mm. It will consist of two Primary Crushers and two Secondary Crushers running parallel, each with a throughput of 3,500t/h. The ore will then be agglomerated and conveyed to an on-off heap leach pad, sized to contain 300 days of ore. Uranium will be recovered from the heap leach pad using a carbonate/bicarbonate solution and ion-exchange. Based on the current mine plan, the majority of the spent ore and waste will be placed back into the shallow open pits, allowing for an overall reduced mining footprint and concurrent reclamation.

The site facilities at Trekkopje will include a solution-process uranium recovery plant, offices, mobile mining fleet service facilities, mobile ore crushers and conveyor systems, upgraded access roads, a temporary construction man camp, power-line infrastructure, an on-site water desalination plant, and a seawater desalination plant, located at the coast near Swakopmund with a pipeline water delivery system.

Beginning in mid-2006, UraMin Inc. (the owner at the time), commissioned SRK to coordinate and lead a multidisciplinary team of global consultants over a 20-month period to develop the Definitive Feasibility Study (DFS) that was issued in 2008. While South African consultants worked on the process, infrastructure, environmental and permitting aspects of the project, SRK worked closely with the client team to review the exploration program to ensure that all work was 43-101 compliant. SRK developed Resource and Reserve statements and mine plans; provided metallurgical, site geochemistry and hydrogeology assessments; performed site geotechnical evaluation and engineering design, including pit slope and heap leach pad design; and performed economic modelling. The study was compiled into an overall DFS document, which was then used to support the mine permit application and the decision to advance the project to construction.

Late in the DFS program, UraMin was acquired by the world energy expert AREVA, as part of their global uranium supply strategy.
