During the 2015-2016 period, reconnaissance portable XRF instrument soil spectrochemical sampling, plus limited rock chip sampling, was continued on the subject tenement. Work concentrated on infill sampling at Erragoonah Hill and over Aster multispectral target A, as well as over the area between the North Wilnaroona and Moorowie prospects. Broadly spaced first pass pXRF sampling was also done over a synclinal fold structure defining the South Frome target. Near the historic Moorowie mine, sampling of mineralised veins as well as of carbonate and/or phosphate rich material gave pXRF readings of >10% combined Pb+Zn. One day was spent reviewing and sampling the Mount John turquoise deposit, in response to an inquiry from an interested third party regarding taking out a option agreement for possibly resuming mining of pits on this prospect. Here mineralisation occurs as copper carbonates within Cambrian Parachilna Formation dolomitic sands and localised cherty silcrete near the contact with underlying Proterozoic Rawnsley Quartzite sandstone. Two pXRF spectrochemical scans made of bedrock close to the pits returned moderately anomalous Pb+Zn (up to 2456 ppm) and strongly anomalous Cu (up to 11,105 ppm). During the 2016-2017 reporting period, work continued on the reconnaissance XRF soil surveying, with work concentrating on infill surveying over several target areas. A total of 1556 soil readings were taken, and 9 rock chip samples collected for multi-element analysis. Strong soil anomalism over a length of 2 km was identified at Target A/Morro Copper, with strong Cu up to 8348 ppm returned. Isolated elevated zinc readings were retuned at Moorowie, however no extensive anomalism was identified. Little to no anomalism was identified at the other target areas identified. During the third year of reporting, the company undertook further XRF soil surveying and rock chip sampling, with infill soil surveys completed over multiple target areas. A total of 1489 soil readings and 11 rock chip samples were collected across the tenement. Work concentrated primarily on the Morro Copper and Mt Chambers target areas with minor work also undertaken at the Moorowie and Target B prospects. Two areas of anomalous copper were further refined within the Target A/ Morro Copper area, with one zone returning soil values up to 13,940 ppm Cu along a 250 m strike length associated with Cambrian stratigraphy. The second zone was associated with Proterozoic quartzite over an 800 m strike length with soil Cu values up to 5354 ppm.
