complete

  • Albion Process leach tanks (SS) to be shipped

from Taiwan in early May 2010

  • Commissioning delayed until early 2011 due to

financing issues

Project Development Program

  • Steps involved

1. Define and collect preliminary key projects and metallurgical data about the likely feed and range of feed material to be treated via the Albion Process 2. Undertake a high level economic assessment of the process (indicative order of magnitude costing exercise) 3. Phase 1 testing- Initiate an orientation testwork program to broadly demonstrate the technical feasibility of the process

and generate key process design parameters to enable a preliminary process feasibility study to be completed

4. Commence a preliminary process study to establish the capital and operating costs for the process specific for project and target feed material 5. Phase 2 testing- Optimize process conditions and undertake testwork on variability samples 6. Phase 3 testing- Continuous pilot trial work 7. Commence bankable feasibility study (BFS) design and costing work leading into basic and detailed engineering and finally plant construction and commissioning
