The Ashburton Project is located in the Ashburton Basin, close to rail and other infrastructure associated with the Paraburdoo iron ore operations of Rio Tinto.
Field reconnaissance work within exploration licence’s (EL’s) 08/2211 and 08/2209, confirmed that these tenements host the greatest thicknesses and areal extent of Cainozoic sediments, which potentially fill palaeochannels draining ranges of Brockman Iron Formation near Paraburdoo. As such, these palaeochannels may host detrital and/or CID iron mineralisation.
Small outcrops of foliated and ferruginised sediments and ironstone were also observed within the basement sediment within EL 08/2211. These outcrops returned up to 51% Fe, 555ppm Zn and 292ppm Ni and may be associated with a deep structure identified from a 2011 Government seismic survey.
A small, wide-spaced soil sampling programme was subsequently undertaken over the interpreted structure. Gold assay results were up to 46 times background, with a maximum of 23ppb. Widespread copper anomalies also trend parallel to the structure, albeit only 3 times above background. Further soil sampling has been planned to extend coverage further to the south to encompass magnetic structural elements.
