Under Recommendations, Mineral Processing and Metallurgical Testion (page 26-1):
Additional metallurgical testwork should be carried out to scale up the process flowsheet for the production of a high-purity graphite product with the specifications targeted based on research and dialogue with end users.
*Continued mineralogical characterization and mineral deportment analysis on a broad range of ore samples representative of the areas to be mined (across the Mineral Resources and at depth)
*Ore variability testing
*Confirmatory tests on regrinding, liquid-solid separation and thickening under the various stages of flotation
*Confirm the grinding media selection does not affect the quality of the product
*Optimization of the purification circuit, including materials handling, liquid-solid separation, and thickening
*Off-gas handling and scrubbing requirements in low-temperature bake treatment
*Dust collection and recycle
*Analysis and characterization of all waste streams and determination of the appropriate methods of disposal
*Methods for effective drying and handling of the final graphite product
*Detailed water balance for the entire process flowsheet
*Materials of construction requirements

Re: the latter point, from page 21-3: Due to the lixiviants used in purification, there is a potential for corrosion and special materials of contstruction for process equipment will be required. Increased costs for special materials of construction have not been included in the current cost estimate,
