Rover 1 Copper-Cobalt-Gold Project
Castile Resources Limited owns the tenements within the Rover Mineral Field southwest of Tennant Creek in the Northern Territory. Its flagship asset, Rover 1, is a copper-gold-cobalt-bismuth project that is planning downstream processing to produce copper metal, cobalt sulphate, gold and bismuth.
Located in the underexplored Rover Mineral Field, approximately 80km east of Tennant Creek, Rover 1 is positioned to benefit from a strategic consolidation of the high-grade gold-copper from the Tennant Creek Mineral Field.
This ready-made pre-development project completed a pre-feasibility study in 2022 proposing an underground operation utilising an electrified load and haul fleet, and a concentrator onsite. A bankable feasibility study is currently in progress and includes a proposed processing facility to produce metals at the Middle Arm Precinct in Darwin. Final metallurgical test works are in preparation for a test pilot plant.
Bismuth has recently been added as a by-product to the bankable feasibility study. In response to recent Chinese export restrictions, bismuth prices have surged by over 500% in key markets, reaching up to A$192,500 per tonne in March 2025.
Since the original pre-feasibility assumptions in 2022, the gold price has nearly doubled, increasing from A$2,640/oz to more than A$5,000/oz in May 2025, significantly enhancing the project’s economic metrics.
