Cashman-Cheroona JVs

Managed by Sandfire Resources Limited (Earning 70% Interest)

During September 2019, Auris entered into a Farm-in with Sandfire Resources Limited in relation to the Cashman Project tenements, E51/1053 and E51/1120, (the Cashman JV). On 4 February 2020 Auris and Northern Star Resources Limited (NST) entered into a Farm-in with Sandfire in relation to the Cheroona Project tenements, E51/1391, E51/1837 and E51/1838, (the Cheroona JV). Sandfire has the right to earn a 70% interest in each of the above projects upon completion of a Feasibility Study on a discovery of not less than 50,000t contained copper (or metal equivalent) on the project.

The southern leases of the projects cover the most prospective VHMS unit – the Karalundi Formation (DeGrussa-host stratigraphy). The Narracoota-Ravelstone contact may have potential for Horseshoe Lights style VHMS

The Orient Cu gossan consists of outcropping chert with visible malachite within the Karalundi Formation and has returned significant results up to 12.8% Cu, 41.7g/t Au, 0.38% Zn, 0.35% Pb and 337ppm As

Previous drilling at Orient has identified a continuation of copper sulphides at depth below the gossan. Best results include:


  • 5m @ 0.86g/t Au from 96m
  • 5m @ 0.25% Cu from 101m
  • 16m @ 0.43% Zn from 101m


  • 9m @ 0.34g/t Au, 0.16g/t Ag, 0.19% Cu from 294m, incl. 1m @ 3.42g/t Au from 301m

Significant copper and gold results have also been returned from regional Air Core Drilling and diamond drilling completed by Sandfire, including results:

  • 1m @ 9.72g/t Au from 40m – CHAC0780
  • 10m @ 0.10% Cu from 10m - CHAC1099
  • 5m @ 0.22% Cu from 0m - CHAC0801
