An area comprising three sub-blocks that cover most of the western side of the Outalpa Inlier in the Olary district was initially explored for possible buried epigenetic White Dam style primary gold mineralisation. In 2015, with a change of licence owner, the exploration focus became shifted onto doing part of a mining pre-feasibility study for producing large amounts of magnetite concentrates from Holocene fine-grained detrital iron-bearing alluvial floodplain sediments. No field work was done in the first licence year. Plans were made to conduct a soil geochemical survey to assist in defining drill targets. During licence Year 2, no work was done. The licence changed ownership during the year. Plans were made to conduct surface geochemical sampling. During licence Year 3, Kingsbluff Minerals (KM) collected 967 grab samples of creek bed and overbank sediments, analysed them via a handheld portable XRF spectrochemical instrument for their iron (Fe) content, and processed them through a pilot plant magnetic separator machine to obtain magnetite-rich concentrate fractions. Consistent yield amounts and grades were not obtained by repeat separation passes done on the same samples, so KM began looking for an alternative and a reliable separation technology to replace the commercial model magnetic separator which had been purchased from Eriez Magnetite Pty Ltd. Problems identified at this stage of the investigation were: (1) the separation technology was not stable and did not produce repetitive and consistent results; (2) the magnetite recovered as concentrate from sampling done in some heavy mineral rich creek sections was less than 10% of the pXRF-indicated iron ore content of the creek sediment samples; and (3) recent decreases of the market price for magnetite fines, plus the current unreliability of the separation technology, were acting to render the envisaged low cost magnetite production project uneconomical to conduct over a large area. During licence Year 4, 479 previously collected grab samples of creek bed and overbank sediments were processed through the magnetic separator. Following numerous tests, problems identified in the previous reporting period continued to be apparent. It is expected that 890 further samples will be processed in the following reporting period. During licence Year 5, 420 previously collected grab samples of creek bed and overbank sediments were processed through the magnetic separator and assayed using portable XRF. A number of problems remain with the separating technology and the recovery of magnetite. The change in iron price along with the uncertainty of the separation currently render the project uneconomical over a large area. It is hoped that the remained 470 samples will be processed in the next reporting period.
