GATEWAY ANNOUNCES KEY BOARD AND MANAGEMENT CHANGES TO DRIVE NEXT CHAPTER OF GROWTH

Peter Langworthy to become Executive Chairman following the promotion of Technical Director Mark Cossom as Managing Director; Trent Franklin to switch to non-executive Director

Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to announce a number of senior board and management changes as it embarks on the next stage of growth at its flagship 100%-owned Gidgee Gold Project in Western Australia and begins the transition from junior explorer to developer.

The changes are designed to ensure that the Company has a strong, well-balanced and experienced senior leadership team in place to oversee the execution of its accelerated exploration strategy and to advance the Gidgee Project rapidly towards feasibility and development.

The Company has experienced significant growth in the last twenty-four months since its strategic refocus on the Gidgee Gold Project, and is entering the next phase of its strategy of building a significant mid-tier Australian gold company.

As a result of this significant growth, the Company’s Managing Director Mr Peter Langworthy , who has played an instrumental role in the evolution of the Company’s growth strategy at Gidgee, will move to the newly created position of Executive Chairman, effective immediately.

Mr Langworthy will continue to be an integral part to the executive management team, providing his vast technical, geological and corporate expertise to the continued exploration and evaluation of the Gidgee Project while also assuming a broader strategic role focusing on business development, growth and strategic opportunities.

Mr Langworthy is one of Western Australia’s best known mining executives, with a distinguished career spanning more than 34 years in mineral exploration and project development. He is best known for his role leading the exploration team at Jubilee Mines NL, that were responsible for several major discoveries leading to its $3.3 billion acquisition by Xstrata.

He has held senior management roles with WMC Resources and PacMin Mining, and also played key roles as a founding director of Capricorn Metals and Northern Star Resources, and served as a non-executive Director with companies including Talisman Mining, Falcon Minerals and Pioneer Resources.

In recognition of his strong performance as Executive Technical Director since his appointment in 2019, the Board has decided to appoint Mr Mark Cossom as Managing Director effective immediately. Mr Cossom will assume full executive responsibility for the day-to-day management of the Company and the exploration programs at Gidgee.

Since his appointment, Mr Cossom has overseen an important period of exploration success and growth for Gateway. The Board believes that Mr Cossom is the right person to take Gateway to the next level, especially given his previous management experience in developing junior explorers into mid-tier miners. He has worked closely with Mr Langworthy on devising the systematic exploration strategies which have recently resulted in several important breakthroughs for the Company, including a number of significant high-grade discoveries.

Mr Cossom is a highly-regarded geologist and mining executive with a strong background in gold exploration and mining geology, coupled with strong economic evaluation and corporate experience. He was a key part of the team that helped transform Doray Minerals from a junior gold explorer to an ASX-300 gold miner, holding a range of senior executive positions.

Mr Trent Franklin will continue to serve the Company as a non-executive Director, providing his invaluable corporate expertise as Gateway enters this next stage of accelerated development and advancement.

Mr Franklin is a qualified geologist with a strong track record of corporate experience advising numerous listed and unlisted companies. He is currently the Managing Director of Enrizen Financial Group and formerly a director of the Australian Olympic Committee Inc. and Australian Water Polo Inc. He is also an Associate of the Australian Institute of Company Directors and acts as Company Secretary of Silver Mines Limited.

Ms Debra Fullarton and Mr Scott Brown will retain their positions on the board as non-executive directors, rounding out what the Company believes to be a talented, experienced and well-balanced board structure with the appropriate balance of skills and a diverse range of corporate and technical expertise to lead the Company in its next stage of exploration and development

Ms Fullarton is an experienced Chartered Accountant with 25 years’ experience in senior roles including as Executive Director, Chief Financial Officer and Financial Manager at Auris Minerals Ltd and De Beers Australia Exploration Limited. She is currently the Group Chief Executive Officer of Westgold Resources Limited.

Mr Brown is a Company Director with 25 years’ experience in project management, business development and logistics across resource sectors, security risk-management and commercial construction, both in Australia and internationally.

Commenting on the restructure and leadership changes, Gateway’s new Executive Chairman Peter Langworthy said: “In many respects this marks the beginning of a really exciting new chapter for Gateway as we move forward to realise our ambition of building a significant mid-tier Australian gold company. Thanks to the hard work and achievements of the past few years, we now have a high degree of confidence that Gidgee is an asset capable of delivering transformational growth for our shareholders over the next few years.

“The board and management changes announced today will ensure that we are appropriately structured from a personnel perspective to deliver that growth. Mark has done an exceptional job as Executive Technical Director since coming on board in 2019 and his appointment as Managing Director is due recognition of his talent, commitment, hard work and strong leadership.

“I am looking forward to embracing a new role as Executive Chairman and continuing to provide counsel, advice, strategic input and high-level leadership to our team as the Company grows to the next level. In this capacity, I will also be focusing on strategic opportunities, business development and potential new growth pathways. I look forward to continuing to work closely with Mark and would also like to acknowledge Trent Franklin’s exemplary contribution to the Company’s growth and success to date. Trent will remain a key part of the Gateway team moving forward as a non-executive Director and significant shareholder, and we look forward to his continued contribution.”

• Peter Langworthy – Executive Chairman;
