Cadence Minerals (AIM/NEX: KDNC; OTC: KDNCY) notes that
The ore sorting test results confirmed that the total rare earth oxide (TREO) recovery through the ore sorter is a linear function, where the lower the head grade, the higher the mass rejection becomes. It is, therefore forecast, based on the average content of alumina and silica for all Yangibana deposits, that 24% of the proposed crusher feed will be rejected by the ore sorters as waste at the expense of only 4% TREO volumes across the life of mine schedule ('LOM').
Highlights
26% upgrade to the life of mine total rare earths oxide (TREO) grade.
96% overall TREO recoveries after ore sorting.
24% upfront mass rejection of primary crusher feed, resulting in: 24% reduction of beneficiation plant reagent consumption.
24% reduction in required tailings storage facility size for the life of mine and effective mitigation of the risk of mining dilution.
Ore sorting test work continues to validate the positive impacts on the Yangibana process flowsheet: Engineering development is progressing to incorporate the ore sorting circuit into the beneficiation process flowsheet.
The variability test work program was completed testing 12 samples from across the Yangibana deposits. The performance of the ore sorters is closely linked to head grade, resulting in LOM mass rejection of 24% with a corresponding increase in average grade of TREO content of 26%.
