The rounding in the above tables is an attempt to represent levels of precision implied in the estimation process and apparent errors in summation may result from the rounding. Ore Reserve has been reported using a ‘Net Smelter Return’ (NSR) cut-off of US$12.02/tonne which includes provision for feed grade, recovery, treatment costs, freight and nickel payables.

Ore Reserves and Mineral Resources Annual Statement and Review

The Company carries out an annual review of its Mineral Resources and Ore Reserves as required by the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code) 2012 edition and the ASX Listing Rules. The review of the nickel Mineral Resources was carried out as at 31 December 2020 and updated subsequently on 31 December 2021, 10 November 2022 and 5 August 2024. The Jaguar Resource estimates have been reported in accordance with the JORC Code 2012 edition and the ASX Listing Rules.

The review of the iron ore Mineral Resources and Ore Reserves was carried out as at The Jambreiro Resources and Reserve estimate have been reported in accordance with the JORC Code 2012 edition and the ASX Listing Rules. The remaining Mineral Resource estimates were prepared and disclosed under the JORC Code 2004 edition. 

The information prepared for the Canavial, and Passabém Resource estimates have not been updated to comply with the JORC Code 2012 edition on the basis that the information has not materially changed since it was last reported.

The Company is not aware of any new information or data that materially affects the information included in this Annual Statement and confirms that all material assumptions and technical parameters underpinning the estimates in the relevant market announcement continue to apply and have not materially changed.

Estimation Governance Statement

The Company ensures that all Mineral Resource and Ore Reserve calculations are subject to appropriate levels of governance and internal controls. Exploration Results are collected and managed by competent qualified staff geologists and overseen by the Exploration Manager. All data collection activities are conducted to industry standards based on a framework of quality assurance and quality control protocols covering all aspects of sample collection, topographical and geophysical surveys, drilling, sample preparation, physical and chemical analysis and data and sample management.

Mineral Resource and Ore Reserve estimates are prepared by qualified independent Competent Persons and further verified by the Company’s technical staff. If there is a material change in the estimate of a Mineral Resource, the modifying factors for the preparation of Ore Reserves, or reporting an inaugural Mineral Resource or Ore Reserve, the estimate and supporting documentation in question is reviewed by a suitably qualified independent Competent Person.

Approval of Ore Reserve and Mineral Resources Statement

The Company reports its Ore Reserves and Mineral Resources on an annual basis in accordance with the JORC Code 2012 Edition.

The Ore Reserves and Mineral Resources Statement is based on and fairly represents information and supporting documentation prepared by competent and qualified independent external professionals and reviewed by the Company’s technical staff. The Ore Reserves and Mineral Resources Statement has been approved by Roger Fitzhardinge, a Competent Person who is a Member of the Australasian Institute of Mining and Metallurgy.  Roger Fitzhardinge is a permanent employee of Centaurus Metals Limited. Mr Fitzhardinge has consented to the inclusion of the Statement in the form and context in which it appears on this website.
