Commenting, Chairperson Neil Herbert said:

"Atlantic Lithium's progress in the reporting period, and subsequently, has been truly remarkable. In July 2021, we were delighted to announce a binding agreement with Nasdaq listed lithium exploration and development company Piedmont Lithium Inc. to fully fund and fast track the Company's industry-leading asset, the Ewoyaa Lithium Project in Ghana, to production.

"The agreement reduces the funding requirements for Atlantic Lithium and its shareholders and sets the Project on the path to becoming West Africa's first lithium-producing mine. With global demand for lithium growing exponentially in line with the adoption of electric vehicles and more sustainable practices, the agreement establishes an entrance for Atlantic Lithium and West Africa to play an integral role in the lithium supply chain. The agreement provides Atlantic Lithium with a strong cash balance to further stimulate growth for the Company.

"Significant exploration developments have been made at the Ewoyaa Project since the start of the period, which continue to add value to the Project. This includes a total of 37,690m RC and diamond core resource drilling and 38,730m of exploration auger drilling completed during the period. This work has culminated in a MRE upgrade to 21.3Mt at 1.31% Li₂O in December 2021, which was upgraded again post-period end to 30.1Mt at 1.26% Li₂O. Earlier this month, we announced the start of RC drilling designed to test new targets to the north and south of the current MRE. To date, approximately 28km² has been auger drill tested, with only 13km² drill tested within our broader 560km² portfolio in Ghana. This demonstrates the true untapped value potential that the Ewoyaa Project offers, which we are looking to capture.

"We were also proud to announce a Scoping Study on Ewoyaa, which incorporated the 21.3Mt JORC resource and demonstrated a significant improvement in project economics and life of mine. The Scoping Study retains a business case for a 2 million tonnes per annum production operation, producing an average 300,000tpa of 6% Li₂O spodumene concentrate and with life of mine revenues estimated to exceed US$3.43bn. The most recent MRE of 30.1Mt is expected to significantly improve the fundamentals of the Project once more, while future resource upgrades are anticipated to further improve project economics.

"These developments have validated the Company's decision to focus whole-heartedly on its lithium portfolio. In line with this intention, the Company, then named IronRidge Resources Limited, successfully restructured and demerged its suite of gold projects in Côte d'Ivoire and Chad into a new private company, Ricca Resources Limited, and renamed as Atlantic Lithium. The demerger was intended to enable the Company to realise its full value potential through the development of the Ewoyaa Project. The process has been a great success and, alongside the advancement of the Project, has put Atlantic on excellent footing going forward.

"The position Atlantic Lithium finds itself in today would not have been possible without the unwavering dedication and hard work of our dear friend and colleague Vincent Mascolo, whose sudden passing on 10 March 2022 was met with great sadness from everyone involved with Atlantic Lithium. Vincent was the driving force behind the Company's success. The outpouring of condolences from the industry and from those that met Vincent has been truly touching and indicates his unique, charming personality. He will be sorely missed.

"We are confident that the foundations that Vincent has laid, combined with the expertise of the current team, will serve as an excellent platform for the Company to attain the great successes that Vincent had always imagined. I'd like to personally welcome both Len and Amanda to the Board. Their support has been unflappable.

"After a highly productive period for the Company, we bring great optimism into the remainder of 2022. I would like to thank our loyal shareholders for their continued support, and we look forward to updating the market of our progress in due course."
