OUR PROJECTS / GREENVALE Project

Halls Reward

Halls Reward is a high-grade copper-gold-silver prospect within the Greenvale Project centred on the former Halls Reward Copper Mine and adjacent mineralised zones. Superior interprets the mineralisation as sheared massive sulphide and vein-hosted copper mineralisation with Cyprus-style VMS characteristics.

High-Grade Sampling Results

Mullock and rock-chip sampling reported on 10 September 2025 returned four high-grade Cu-Au-Ag assays, including:

  • 46.50% Cu, 6.58 g/t Au and 24.5 g/t Ag
  • 18.82% Cu, 4.59 g/t Au and 56.3 g/t Ag
  • 16.87% Cu, 0.86 g/t Au and 84.5 g/t Ag
  • 12.97% Cu, 0.26 g/t Au and 21.8 g/t Ag

Earlier sampling around the historical workings also returned high-grade Cu-Au-Ag values, including 20.13% Cu, 0.21 g/t Au and 58 g/t Ag and 1.62% Cu, 14.48 g/t Au and 22 g/t Ag.

Historical Drilling and Target Scale

Historical drilling reported by Superior includes 4.0 m @ 8.8% Cu from 31.6 m, including 2.4 m @ 13.5% Cu, and 7.0 m @ 3.5% Cu from 64.0 m, including 1.8 m @ 7.6% Cu.

Superior reported in January 2026 that historical government drill-hole data confirms a southerly extension of the previously mined high-grade lode and at least one additional lode that can be traced for up to 2 km. 

 
Current Exploration Status

Superior announced an RC and diamond drilling program of up to 3,000 m across Halls Reward and Telegraph. Adverse weather delayed final design and planning during 2026. As at 31 July 2026, planned drilling remained consistent with the previously announced program, with finalised details yet to be announced. Superior also reported that land access arrangements had been finalised to enable near-term exploration at Halls Reward.
