Great Western Exploration Limited announced the completion of a helicopter-borne EM survey at the Company's Fairbairn Nickel-Copper Project. The Fairbairn Nickel-Copper Project is located 900km north-east of Perth, on the northern margin of the Yilgarn Craton and within the Earaheedy Basin. The Yilgarn Craton margin is highly prospective for base metal deposits and host to both the Julimar and Nova Deposits.

Little previous exploration has been completed at Fairbairn, with work completed during the 1980s and early-1990s focussed on diamond exploration and not magmatic nickel-copper style mineralisation. Great Western has now completed a helicopter-borne electromagnetic (EM) survey over a highly prospective portion of the project, to define Julimar/Nova style magmatic Nickel-Copper targets. The EM survey focused on zones of magnetic highs (Figure 2), interpreted as obscured mafic/ultramafic units below shallow cover, and two early-1990s drill holes focussed on diamond exploration which recorded anomalous nickel results (GTE ASX Announcement 21 March 2022).

These results included: 12m @ 1,835ppm Ni from 22m (M018), including a maximum assay of 2,130ppm Ni, and 20m @ 1,214ppm Ni from 28m (M017). Geoscience Australia's 2016 report `Potential for intrusion-hosted Ni-Cu-PGE sulphide deposits', interpreted that where major crustal structures extend into the craton margin, the thinner margin crust at these locations would allow these structures to more easily "tap" the mantle, resulting in metal rich fluids to ascend and potential form economic metal accumulations. Post the release of this report the Julimar deposit was discovered in this geological location.

The Company interprets that the Ockerburry Fault (Figure 1) that flanks the Fairbairn Nickel-Copper Project is an example of one of these structural features, with high potential for magmatic nickel-copper style mineralisation to have formed within the Fairbairn Project.
