All information contained in this presentation is of a general nature. Potential investors are cautioned against using the content of this

presentation, in isolation, for making investment decisions and should also refer to Santana Minerals Limited (‘Santana’) Annual Reports and

ASX/NZX:SMI releases. For further information about Santana visit our website at www.santanaminerals.com.

Best efforts have been made to ensure the accuracy of information contained (at the time of preparation). Where forward targets and/or

assumptions have been included – all such instances are indicative only and subject to alteration and/or cancellation as and when the

management of Santana determines.

Research and advice of a qualified financial advisor or accountant are strongly recommended to anyone considering investing in listed

company securities, including those of Santana.

The Prefeasibility Study, including the production target and the forecast financial information derived from the production target, referred to

in this Presentation (PFS) was released to the ASX on 1 July 2025. This Presentation includes summary excerpts from the PFS and does not

purport to be all-inclusive or complete.

Forward-Looking Statements

This Presentation contains various forward looking statements. Forward-looking statements in this presentation include, but are not limited

to, statements regarding the production target, financial information based on that production target and statements statements with

respect to Santana’s future plans, strategy, activities, events or developments the Company believes, expects or anticipates will or may occur.

By their very nature, forward-looking statements require Santana to make assumptions that may not materialize or that may not be accurate.

The Company has concluded that it has a reasonable basis for providing these forward-looking statements, including the production target

and the forecast financial information included in this Presentation. The detailed reasons for these conclusions are outlined throughout the

ASX releases dated 1 July 2025. However, no assurance can be given that these expectations will prove to have been correct, as actual results

and future events could differ materially from those anticipated in the forward-looking statements. Accordingly, viewers are cautioned not to

place undue reliance on forward-looking statements. Santana does not undertake to update publicly or to revise any of the included forward-

looking statements, except as may be required under applicable securities laws.

To achieve the range of outcomes anticipated in the PFS, the PFS estimates that financing in the order of A$277 million will be required.

Santana believes that there are reasonable grounds for the assumptions it has made in satisfying itself that the requisite funding for the

development of the Project will be available when required. However, Shareholders and prospective investors should be aware that there is

no guarantee Santana will be able to secure this funding as required, and it is possible that the terms available may be dilutive or otherwise

adversely impact the value of Santana’s current shares. Additionally, Santana may explore alternative value-creating strategies, such as

divesting some or all potential revenue streams from precious metals or a full or partial sale of its interest in the Bendigo-Ophir project.

Cautionary Statement – Inferred Resources Included in Production Target

Of the Mineral Resources planned for extraction under the PFS production model approximately 93% is within the Indicated Resources category, with

the balance (7%) being classified within the Inferred Resources category. 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 will be realised.

Competent Persons Statement

The production target and the forecast financial information derived from the production target set out in this presentation were first contained in a

public announcement released to the ASX on 1 July 2025. The Company confirms that all material assumptions underpinning the production target and

the forecast financial information derived from it continue to apply and have not materially changed.

The information in this report that relates to Mineral Resources is based on information contained in the following public announcements:

4 March 2025 – ASX Announcement titled “RAS Mineral Resource Estimate Review”

15 November 2024– ASX Announcement titled “Bendigo-Ophir Pre-Feasibility Study”

28 September 2021 – ASX Announcement titled “Bendigo-Ophir Gold Resources Increased 155% to 643k Oz”

The information in this report that relates to Ore Reserves is based on information contained in the public announcement made to the ASX on 1 July

2025.

A copy of these announcements are available to view on the Santana Minerals Limited website www.santanaminerals.com or on the ASX platform

www.asx.com.au.

The reports were issued in accordance with the 2012 Edition of the JORC Australasian Code for Reporting of Exploration Results, Mineral Resources and

Ore Reserves. The Company confirms that it is not aware of any new information or data that materially affects the information included in the original

market announcements referenced above and, in the case of the Mineral Resource estimates, that all material assumptions and technical parameters

underpinning the Mineral Resource estimates in the relevant announcements continue to apply and have not materially changed. The Company

confirms that the form and context in which the Competent Person’s findings are presented have not been materially modified from the original market

announcements.

The information in this report that relates to this March 2025 RAS Mineral Resource Estimates (MRE) and to the November 2024 SRX and SRE MRE, is based on work completed by Mr Kerrin Allwood, a Competent Person (CP) who is a
Member of The Australasian Institute of Mining and Metallurgy (AusIMM). Mr Allwood is a Principal Geologist of GeoModelling Limited, Petone, New Zealand and has sufficient experience which is relevant to the style of mineralisation

and type of deposit under consideration and to the activity which is being undertaken to qualify as a Competent Person as defined in the 2012 Edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and

Ore Reserves”. Mr Allwood consents to the inclusion in this report of the matters based on his information in the form and context in which it appears. Mr Allwood and GeoModelling Limited are independent of Santana Minerals Ltd.

The information in this report that relates to prior 2021 Mineral Resource Estimates (2021 MRE) for CIT deposit completed by Ms Michelle Wild (CP) (ASX announcement on 28 September 2021) continue to apply and have not materially

changed.
