Rover Project

Location

Close to airport, railway, highway and gas pipeline infrastructure.

The Rover Project is close to the Tennant Creek commercial airport, the Adelaide to Darwin railway, the Stuart Highway and the Amadeus natural gas pipeline. That infrastructure advantage remains central to the development case at Rover 1.

Opportunity

Iron Oxide Copper Gold opportunity.

The main mineralisation style within the project is Iron Oxide Copper Gold. This deposit type is known to host large scale economic copper and gold mineralisation such as Olympic Dam in South Australia and Candelaria in Chile.

The Rover Mineral Field is interpreted to be a southern repeat or extension of the Tennant Creek Mineral Field. Tennant Creek IOCGs have historically produced approximately 157t of gold, 345,000t of copper, 14,000t of bismuth, 220t of selenium and 56t of silver from 130 mines.

Mineral Resources

Three advanced deposits anchor the field.

Rover 1 carries a JORC 2012 Mineral Resource of 6.9Mt at 1.74 g/t Au, 2.07 g/t Ag, 1.2% Cu, 0.14% Bi and 0.06% Co for 386koz gold, 459koz silver, 83kt copper, 9.4kt bismuth and 4.1kt cobalt inclusive of indicated and inferred material.

Explorer 108 and Explorer 142 provide additional defined mineral resources, broadening the Rover Project from a single deposit into a larger mineral field opportunity.

Exploration

More than 40 targets still to be fully tested.

The project area remains underexplored outside the current resources, with more than 40 targets yet to be fully investigated. Because the entire project area sits beneath cover, Castile has relied on high-resolution geophysics and new techniques such as Ambient Noise Tomography to define drill targets with more confidence.
