CHAIRMAN'S ADDRESS

1. Welcome

Good morning Ladies and Gentlemen.

I have pleasure in welcoming you to the 2024 Annual General Meeting for Macarthur Minerals Limited.

My name is Cameron McCall, Executive Chairman and CEO of Macarthur, and I preside as the Chairperson of today's meeting in accordance with the constitution.

2. Format of Meeting

I will provide some comments on the company's progress. Following that, we will proceed with the formal agenda of the meeting.

3. Open of Meeting / Quorum

It is now 10.00AM and there being a quorum present, I formally declare the Meeting open.

4. Introductions

I'm joined this morning by:

• Alan Spence Phillips (Non-executive Director);
• Ryan Welker (Non-executive Director);
• Ian McCall (CFO); and
• Mima Wirakara (Company Secretary).

Meeting apology was received from Andrew Suckling (Non-Executive Director) who lives in New York and unable to travel to attend in person.

Steve Stavrou and Aakash Gopal, representing our auditors RSM Australia Pty Ltd, are also present. Steve is available to answer any relevant questions pertaining to audit matters that you may wish to ask later in the meeting, and I thank him and Aakash for attending today.

We also welcome Jessie Yerma and her team from Computershare and would like to acknowledge and thank you, for your assistance with the conduct of today's meeting.

5. The Year in Review

On behalf of the Board and management of Macarthur Minerals, I am pleased to report positive progress in the final phase of the development of our Lake Giles Project, despite challenging equity market conditions for junior miners and a fluctuating global economy.

Today, I will focus on two key outcomes essential for realising value for all shareholders:

1. The Company continues to work with Golden Valley (GVL) on contracting and permitting requirements that will see hematite exported from the Lake Giles in late 2025.
2. Macarthur continues to seek a strategic partner for the development of the Lake Giles magnetite project

Lake Giles Hematite Project

Macarthur has made good progress in advancing its strategic projects and overall company development this past year.

The Company have entered into a binding term sheet with Golden Valley, a privately owned mining company that produces and exports iron ore from Western Australia. This agreement grants GVL the right to extract hematite ore from our Lake Giles Ularring Hematite Project and Treppo Grande Iron Project, while explicitly excluding magnetite mining from the 1.3 billion-tonne Lake Giles Moonshine Magnetite Project. Key terms include:¹

1. Initial payment of $250k to Macarthur on the signed term sheet.
2. Two subsequent payments of $250k on 30 September 2024 and 31 December 2024.
3. A $5 million payment upon the sale of the first million tonnes, and a further $5 million upon the sale of the second million tonnes, alongside a $1 per tonne royalty for the life of the mine

Lake Giles Magnetite Project

The Golden Valley right to mine will establish critical route to market corridors that will materially benefit the value of the magnetite project.  While Australian iron ore mining is primarily hematite-based, the global demand for cleaner, high-grade magnetite ores is increasing. Macarthur's investment in delineating over a billion-tonne resource, along with rail and port capacity through Esperance, positions Lake Giles as a valuable long-term asset. We continue to engage with strategic partners for the magnetite project, and the dedicated route to market through Esperance Port will significantly enhance its value.

Financing

In July 2024, Macarthur successfully completed a private placement raising A$1.282 million, with subscriptions totalling 24,193,831 ordinary shares at AUD $0.053 with 12,096,915 attaching options at an exercise price of A$0.10 expiring on 29 July 2026.²

Infinity Mining Investment

Macarthur is the largest shareholder in Infinity Mining Ltd. (ASX: IMI) which resulted from the spin-out of our Pilbara Assets in 2021. These assets cover approximately 781 km² in the Pilbara region and include a diverse portfolio for lithium, gold, copper, and nickel. Infinity's primary focus is the South Tambourah project, which has shown promising results, including significant lithium, rubidium, and caesium assays.

Additionally, with the downturn in the lithium market, IMI has actively acquired a new portfolio of highly prospective gold and copper projects in New South Wales, Victoria, and Tasmania from various vendors. These projects were chosen based on historical exploration data and the success of other companies targeting VMS-style copper and base metals, as well as intrusive-related gold projects.³

As we focus on core fundamentals and project delivery, we are implementing a cost reduction program to ensure the company's viability until we generate revenue from royalties. We are committed to keeping our shareholders informed and greatly appreciate your continued support.

Before we proceed to the formal business of the meeting, I would like to take this opportunity, on behalf of the Board, to extend our sincere appreciation to Andrew Suckling, who is retiring today as an Independent Director. Andrew's exceptional contributions have been invaluable throughout his tenure.⁴

Thank you.

Cameron McCall
Executive Chairman
