ROVER 1 PRELIMINARY FEASIBILITY STUDY (PFS) COMPLETE

GOLD, COPPER, COBALT AND 96.5% MAGNETITE DOWNSTREAM PRODUCTS PRODUCED IN AUSTRALIA

The Rover 1 PFS models an underground mine build with a modern 500,000tpa processing plant focused on the production of gold, copper, cobalt and magnetite downstream products delivering strong economic outcomes with an initial project life of 8 years.

Financial Highlights include:
• A Pre-Tax NPV6.5% of $451.7 million with an IRR of 46%.
• Total Revenues of A$1.94 billion.
• Pre-tax cash flow of A$1.02 billion.
• An Undiscounted Pre-tax Net Cash Flow of A$686 million.
• Capital cost estimate of A$279.5 million (Including Processing Plant A$160.7M)

EXPLORER 108 PROSPECT

Targeting High Grade Primary Copper System

Explorer 108 has defined a lead-zinc discovery with a polymetallic resource of approximately 12Mt @ 3.24% Zn, 2.00% Pb and 11.1/t Ag. Castile is considering high grading the lead zinc resource as a potential future feed source for the proposed Rover 1 Infrastructure.

EXPLORER 142 PROSPECT

Targeting High Grade Gold Zone

Explorer 142 has a defined Inferred copper resource of 176kt @ 5.21% Cu and shares similar geological characteristics with Rover 1.

ROVER 4 PROSPECT

New Copper Gold Resource Announced

Rover 4 is located 2kms from the Rover 1 Project. A maiden Mineral Resource Estimate (MRE) was announced in November 2022 providing optionality for further copper and gold inventory for the proposed Rover 1 infrastructure.

Investability Interview | The India Critical Minerals Opportunity

Castile attended the Australian Government’s 2024 Critical Minerals Delegation to India, where downstream critical minerals Australian companies met with large Indian conglomerates and end users of critical minerals, as part of an Australian India Business Exchange (AIBX) initiative to boost trade and investment between India and Australia.
