The following notices and disclaimers apply to this presentation and you are therefore advised to read this carefully before reading or making any other use of this presentation or any information contained in this presentation. This presentation has been authorised for release to the Australian Securities Exchange ("ASX") by the Board of directors of Rox ("Board").

This presentation may not be distributed in any jurisdiction except in accordance with the legal requirements applicable in such jurisdiction. Recipients should inform themselves of the restrictions that apply in their own jurisdiction. A failure to do so may result in a violation of securities laws in such jurisdiction.

Summary information

This presentation contains general and background information about Rox's activities current at the date of this presentation (unless otherwise indicated). The information in this presentation is in summary form and does not purport to be complete nor does it contain all the information in relation to Rox. It should be read in conjunction with Rox's other periodic and continuous disclosure announcements lodged with the ASX at www.asx.com.au. Recipients should conduct their own investigations and perform their own analysis in order to satisfy themselves as to the accuracy and completeness of the information, statements and opinions contained in this presentation.

Not an Offer

This presentation is for information purposes only. Neither this presentation nor the information contained in it constitutes an offer, invitation, solicitation or recommendation in relation to the purchase or sale of shares in any jurisdiction.

Financial information

All financial information in this presentation is in Australian dollars unless otherwise stated. US dollar presentation is calculated by reference to a AUD:USD FX rate of 0.72, as at 8 May 2026.

Non-IFRS Financial Measures

The Company uses certain financial measures to assess how the Project is projected to perform. These financial measures, such as net present value (NPV) and internal rate of return (IRR) (collectively referred to as Non-IFRS Financial Measures) are not recognised under International Financial Reporting Standards (IFRS).

The Company considers the Non-IFRS Financial Measures provide useful information about the estimated financial forecasts derived from the DFS, however, they should not be considered in isolation or as a substitute for measures of performance or cash flow prepared in accordance with IFRS.

Since the financial forecasts and economic discussion in this announcement are not based on IFRS, they do not have standardised definitions and the way these measures have been derived may not be comparable to similarly titled measures used by other companies. Investors should therefore not place undue reliance on these Non-IFRS Financial Measures.

Not investment advice

This presentation does not constitute investment advice and has been prepared without taking into account the recipient's investment objectives, financial circumstances or particular needs and the opinions and recommendations in this presentation are not intended to represent recommendations of particular investments to particular persons. Recipients should seek professional advice when deciding if an investment is appropriate. All securities transactions involve risks, which include, amongst others, the risk of adverse or unanticipated market, financial or political developments.

Important Information and Disclaimer

Production Target

The Production Target (and forecast financial information derived from the Production Target) referred to in this announcement is underpinned by Indicated Mineral Resources of approximately 80% and Inferred Mineral Resources of approximately 20% over the DFS mine period. The first four years of the Production Target is underpinned by approximately 89% Indicated Mineral Resources with 11% classified as Inferred Mineral Resources. The total Life of Mine Production Target includes 20% Inferred Resources ounces, 5% Indicated Resource ounces outside of Reserve and the remaining 75% is underpinned by Probable Ore Reserves. There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the Production Target itself (or the forecast financial information) will be realised.
