Corporate Overview

Corporate Overview

Rover 1 is the flagship pre-development asset.

The Rover Mineral Field is interpreted to be a westerly extension of the Tennant Creek Mineral Field. The high grades of gold and copper hosted in banded ironstones at Rover 1 display similar characteristics to the Warrego Deposit in Tennant Creek.

A virgin lead-zinc deposit at Explorer 108 and a high-grade copper prospect at Explorer 142, both with contained mineral resources, have also been uncovered by previous exploration within the Rover Mineral Field.

A scoping study and Mineral Resource completed in 2011 on the Rover 1 deposit calculated more than one million ounces of gold equivalent when taking only copper credits into account at prevailing metal prices.

The Warumpi Project

District-scale tenure in the West Arunta.

The Warumpi Project is a highly prospective grass-roots exploration project located approximately 300 km west of Alice Springs in the West Arunta region of the Northern Territory. The age of the Warumpi Province is significant because stratigraphy from this period hosts world-class stratabound Pb-Zn-Ag mineralisation systems such as Broken Hill, Mount Isa Group, McArthur River and Century.

Technical Base

Backed by a large inherited dataset.

Castile has the benefit of the data from previous drilling programs across the Rover Mineral Field, amounting to approximately 85,000 metres of drilling together with the associated technical assessment and study work completed by previous owners including Metals X and Westgold Resources.

Portfolio Position

Development and exploration inside one company story.

In practical terms, the company combines a development-ready flagship at Rover 1 with mineral resource upside at Explorer 108 and Explorer 142, plus earlier-stage exploration potential at Warumpi. That balance is what gives the corporate story its depth.
