Rover 1

The flagship: a high-grade IOCG with five revenue streams.

Rover 1 is positioned to produce gold doré, 99% copper, 99% cobalt, 96.5% magnetite and bismuth from a single underground operation. The 2022 Pre-Feasibility Study models a modern 500,000 tpa processing plant; the Bankable Feasibility Study is due June 2026.

Project video

A four-minute walk through the case.

The project video presents the headline outcomes from the 2022 Rover 1 PFS, the proposed mining and processing design, and the downstream product strategy.

Downstream products

Five revenue streams from one underground mine.

  • Gold doré, refined to finished form on Australian soil.
  • 99% copper, produced at the Middle Arm precinct, Darwin.
  • 99% cobalt, alongside the copper stream.
  • 96.5% magnetite as a saleable product.
  • Bismuth concentrate, with China currently producing 83% of global 4N supply.

Prospect context

Jupiter and the broader Rover 1 system.

Rover 1 is an IOCG polymetallic deposit. The 2020 drilling season materially improved the understanding of higher-grade gold zones within the Jupiter lode and related structures.

The reinterpretation indicates Jupiter Deeps may be the depth extension of Jupiter West and continue through to the Ganymede intercepts.

2020 drill program

Bonanza intercepts in the Jupiter lode.

  • 30.4m at 35.6 g/t Au and 1.46% Cu in Hole 20CRD001 reshaped Castile's view of the gold zone within the Jupiter lode.
  • The 2020 drilling program highlighted high-grade bonanza gold zones similar to the super-rich lenses historically mined in the Tennant Creek goldfields.
  • Data from the 2020 season supported a reinterpretation of fluid pathways: Jupiter Deeps may extend through Jupiter West to the Ganymede intercepts.
