A review of previous exploration data for the subject licence area, located 40 km north-west of Hawker, has focussed on zinc. Previous stream sediment sample assay results were digitised, and a structural review of the region (including other Copper Range tenements in the area) was undertaken to identify suitable structural settings for Beltana-style zinc silicate mineralisation. The reviews show that the Cambrian limestones have been thoroughly explored by previous explorers using stream sediment sampling, and that all anomalous zinc values were traced back to ironstone developments at the Parachilna Formation / Wirrapowie Limestone contact. However, Beltana was discovered from anomalous stream sediment samples of up to 760 ppm Zn, yet higher values than this, of up to 1215 ppm Zn, have been recorded in the Chace Range / Druid Range syncline (on EL 3647). Nevertheless, previous explorers did not get any encouragement from field investigations following up anomalous stream sediment samples. Copper Range thought that due to the nature of zinc silicate mineralisation, a broad scale EM and gravity survey would be best suited to identifying potential targets within EL 3647 and other adjoining tenements. A brief reconnaissance field visit and further review of earlier exploration data has recently been completed. Originally the Mount Josephine licence was taken up to explore for sediment-hosted copper mineralisation associated with basin-scale fluid flow, identified as anomalous alteration zones on Aster satellite imagery. Copper Range identified several zones of alteration associated with favourable strata within the tenement, but follow-up soil and rock chip sampling was not encouraging. It was concluded that the tenement portion now relinquished is of lower mineralisation potential than that part which is being retained.
