Rover 1

The Rover 1 Project is poised to produce a range of downstream critical and precious minerals, including gold doré, 99% copper, 99% cobalt, and high-grade 96.5% magnetite. The Pre-Feasibility Study completed on 5 December 2022 models an efficient underground mining operation with a modern 500,000 tonnes per annum processing plant.

Video summary of the Rover 1 case.

The project video presents the outstanding results from the 2022 Rover 1 PFS, including the proposed mining and processing designs and the downstream product strategy.

Downstream critical and precious mineral products.

  • The Rover 1 Project is poised to produce gold doré, 99% copper, 99% cobalt and high-grade 96.5% magnetite.
  • The Pre-Feasibility Study completed on 5 December 2022 models an underground mine build with a modern 500,000 tonnes per annum processing plant.
  • The project is designed to produce high-value gold, copper, cobalt and magnetite downstream products.

Jupiter and the broader Rover 1 system.

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

2020 drilling outcomes.

  • 30.4m at 35.6 g/t Au and 1.46% Cu in Hole 20CRD001 changed the way Castile views the overall gold zone within the Jupiter lode.
  • The 2020 drilling program highlighted high grade bonanza gold zones of relatively concentrated dimensions, similar to the super-rich lenses historically mined in the Tennant Creek goldfields.
  • Data from the 2020 drill season supported a reinterpretation of fluid pathways and a working view that the Jupiter Deeps structure may extend through Jupiter West to the Ganymede intercepts.

Updated interpretation across Jupiter West and Ganymede.

Incorporation of the 2020 drill data enabled a reinterpretation of fluid pathways and supports the working hypothesis that Jupiter Deeps may be the depth extension of the Jupiter West orebody and continue through to the Ganymede intercepts.
