The Heron South deposit is located 15km south-southeast of the historic Gidgee mill and has previously been mined by open cut methods. The current MRE for the Heron South deposit is 1.09Mt @ 1.7 g/t Au for 60,500oz. (refer to Horizon Gold Ltd ASX announcement dated 25 July 2022) (Figure 1).

The Heron South deposit is currently over 600m long and hosted by a north-south striking, steep easterly dipping shear zone within basalt and minor interflow sediments. Gold mineralisation is associated with quartz-carbonate-pyrite-arsenopyrite-pyrrhotite veining within strongly silica-sericite-carbonate altered basalt. High grade lodes display shallow to moderate north and shallow south plunges (Figure 2). The mineralisation remains open along strike to the north and south and at depth down dip and down plunge.

Significant intersections (>40 Au gram x metres) from the Heron South deposit include*:

(0.5g/t Au lower cut-off, maximum 3m internal waste – *refer to Horizon Gold Limited ASX Announcement dated 15 February 2021)
