ABSTRACT:Flinders Mines Limited (ASX: FMS) is pleased to announce an update to the PIOP Mineral Resource at the Company’s wholly owned Pilbara Iron Ore Project “PIOP” in Western Australia. Following the completion of a drilling campaign and subsequent metallurgical laboratory analysis, Snowden Mining Industry Consultants (Snowden), on behalf of Flinders Mines Ltd (FMS), has re-estimated and updated the Mineral Resource estimate. The cut-off grades are based on product optimisation carried out by Snowden based on metallurgical regressions provided by FMS for two ore processing facilities – known as Ore Processing Facility 1 (OPF1) and Ore Processing Facility 2 (OPF2). The OPF1 processing route includes crushing, wet scrubbing, wet screening and hydrocyclone desliming. FMS propose to beneficiate relatively low grade DID1, DID2 and DID3 (detrital) mineralisation using the OPF2 processing route which includes crushing, scrubbing, wet screening and dense media separation (DMS). The metallurgical regressions based largely on the 2017 drilling campaign samples support this as being a viable processing path. This maturation work confirms one of the key assumptions in the independent strategic review studies conducted in February 2017, that detrital ore has the potential to be upgraded into economic saleable product and hence included in the resource estimate. The quantity and grades of saleable and economic product are now the subject of further detailed mine planning and process engineering activities which remain an ongoing focus for FMS. It should be noted that as this work proceeds, the yields from processing some of the detrital material are relatively low, and when combined with ore loss of resource from mining and potential sterilisation of areas sensitive to traditional owners, that the Ore Reserve estimate may be materially lower than this revised resource estimate.
