Gateway Announces Board Restructure as it Enters New Exploration Phase at Yandal

Highly experienced and well regarded mining executives, Andrew Bray and Anthony McClure, to join the Gateway Board

HIGHLIGHTS

• Mr Andrew Bray joins the leadership team as Executive Chairman, bringing extensive knowledge of the Yandal Project.

• Mr Anthony McClure joins the board as Non-Executive Director.

• Non-Executive Directors Mr Trent Franklin and Mr Peter Lester to step down from the board due to commitments with other roles.

• Current Executive Chairman, Mr Peter Langworthy, to transition to Non-Executive Director.

• The Board refresh aims to ensure a strong, well-balanced and experienced senior leadership team to oversee a new phase of exploration at the newly acquired Yandal Gold Project.

Management Comment

Andrew Bray, newly appointed Executive Chairman of Gateway, said: “I am looking forward to taking on the role of Executive Chairman of Gateway and to be re-engaging with the Yandal Project – a project I have always believed offered tremendous potential for significant further discoveries. During my time at Strickland, Anthony (Tony) McClure and I worked closely to consolidate the Yandal tenement package and add considerable value through successful exploration. We were also able to unlock substantial liquidity via the sale of the Millrose Project to Northern Star Resources Ltd in 2023.

This work positioned Strickland to take on its flagship, tier-one Rogozna Project in Serbia, which is rightly now Strickland’s prime focus. As a result of the transaction between Strickland and Gateway, the Yandal Gold Project will now be Gateway’s flagship project, with a renewed focus on undertaking significant drilling programs and delivering further gold discoveries in what is a highly strategic part of the Western Australian goldfields.

I am delighted to be working with Tony again, whose extensive experience and knowledge will prove invaluable as we take Gateway forward.

On behalf of the Board, I would like to extend our sincere thanks to Trent Franklin and Peter Lester for their significant contributions to Gateway. Both Trent Franklin and Peter Lester’s leadership and commitment have been instrumental in positioning the Company for the next phase of growth. Also, I would also like to thank Mr Peter Langworthy who stepped up as Executive Chairman of the Company in 2024 and is now moving to a NonExecutive Director role.

We look forward to building on these strong foundations and delivering meaningful outcomes for our shareholders."
