George Bennett, CEO of Rainbow, commented: "We are delighted to welcome James to the Board and Brent to Senior Management at a pivotal point in Rainbow's development. As we advance our two world-class rare earth projects at Phalaborwa in South Africa and Uberaba in Brazil towards development, it is increasingly important that we support the Company's commercial, strategic and ESG capabilities. James brings a unique combination of commercial understanding, project financing expertise, government and stakeholder engagement experience, and a proven track record of helping develop and fund critical minerals projects internationally, while Brent's extensive ESG and environmental leadership experience will also be invaluable, helping to  ensure that responsible environmental and social stewardship remains at the heart of our operations and growth strategy."

James Beams - Executive Director

As Executive Director, James will be responsible for supporting and integrating offtake negotiations and agreements, project finance and material contracts for Rainbow as it evolves into an operating business.

He has worked extensively throughout Africa, South America, Europe and China and has held a number of senior executive and non-executive positions in the mining sector.

Most notably, James spent 14 years with Anglo American plc, where he held several senior leadership positions, including Chief Financial Officer of the company's copper business in Chile and Head of Business Development for Base Metals. During this period, he was involved in the evaluation and development of major mining projects, capital allocation, business development opportunities and joint venture governance.

James has held executive and board positions with several mining companies focused on project development, financing and strategic growth. He currently serves as non-executive director of Trinity Metals Limited, a mining company focused on tin and tungsten that is one of the largest private sector employers in Rwanda.

James Beams, Executive Director of Rainbow, commented: "I am delighted to join Rainbow at such an exciting stage in its evolution. The Company has established two highly attractive rare earth opportunities in South Africa and Brazil, both of which have the potential to become important sources of critical minerals required for many of the advanced technologies upon which we increasingly rely. I look forward to working with the Board and management team as Rainbow advances these projects towards development and seeks to unlock value for all stakeholders."

Brent Holme - Environment, Social and Sustainability Manager

As Environmental, Social & Sustainability Manager, Brent will ensure environmental, social and sustainability considerations are integrated across the Company's operations. His role will be particularly important in the context of the development of Phalaborwa as a brownfield site.

Brent is a South African citizen who brings nearly two decades of experience in environmental, social and sustainability management, with a strong track record advising mining, industrial and renewable energy companies across Africa and internationally. He joins Rainbow from Hatch, where he served as Environment and Sustainability Lead for Africa, leading a multidisciplinary team and supporting major mining and infrastructure projects. Prior to this, Brent held senior environmental leadership roles at Marsh Advisory and founded his own environmental consultancy.

Brent holds a BSc (Hons) in Environmental Sciences from the University of Johannesburg and has extensive expertise in environmental and social impact assessments, environmental and social due diligence, environmental risk management, sustainability reporting and regulatory compliance. His experience includes supporting mining and infrastructure projects throughout Africa and developing ESG and environmental risk frameworks aligned with international best practice.

Brent Holme, ESS Manager of Rainbow, commented: "I am  delighted to be joining Rainbow at such a pivotal point in its growth. The Company has a genuinely compelling story to tell; recovering critical rare earths from an existing waste stream  speaks directly to the global energy transition and the circular economy, and it is rare to find a project that ticks both boxes so clearly. In the near term, my focus will be on finalising Phalaborwa's Environmental and Social Impact Assessment to local and international standards, ensuring compliance with lender requirements, and steering the project through permitting as we advance towards production. Looking further ahead, I am also looking forward to working with our partners, The Mosaic Company, on the Uberaba project in Brazil."

About Rainbow:

Rainbow Rare Earths aims to be one of the lowest cost suppliers of critical rare earth raw materials in the western world supply chain. Advancing two core projects, Phalaborwa in South Africa and Uberaba in Brazil in partnership with The Mosaic Company, Rainbow is one of the most advanced market participants pursuing secure, near-term and globally competitive upstream supply of rare earths products crucial for industrial, energy transition, and defence applications. 

With a unique project portfolio focused on the recovery of rare earth elements from phosphogypsum, a by-product of fertiliser production, Rainbow's projects avoid traditional mining and front-end processing stages. This represents a significant competitive advantage in bringing sustainable, long-life and low cost supply of rare earths to market.
