Rambler Metals and Mining PLC - Operational Update

London, England, Newfoundland and Labrador, Canada - Rambler Metals and Mining plc (AIM: RMM) ('Rambler' or the 'Company'), a copper and gold producer, explorer and developer, announces that its wholly-owned subsidiary Rambler Metals and Mining Canada Limited ('RMMCL') which has been operating under the protection of the Companies' Creditors Arrangement Act ('CCAA') since 27 February 2023 pursuant to an Amended and Restated Initial Order most recently amended on 15 March 2023 (the 'ARIO') by the Supreme Court of Newfoundland and Labrador ('Court') has ceased operations at the Ming Mine, the Nugget Pond Mill and Goodyears Cove effective as of 19.00pm Newfoundland Time 29 March 2023

RMMCL's cessation of operations was the direct result of a dispute which RMMCL has with Transamine Trading S.A. ('Transamine') regarding the payment of approximately US$880,000 that was due from Transamine on 24 March 2023 and an additional payment of approximately US$1.78 million that is due from Transamine on or around 30 March 2023. Transamine has advised Rambler that it does not intend to make those required payments

RMMCL along with Grant Thornton Limited ('GT'), who has been appointed as the Monitor by the Court in the CCAA proceedings for RMMCL, will be applying to the Court to address Transamine's failure to pay, the cessation of operations, and further issues regarding the Sales and Investment Solicitation Process ('SISP') as soon as possible. It is not expected that operations will resume for the balance of the SISP. All employees, suppliers and other stakeholders have been, or are in the process of being informed, and RMMCL will be carrying out essential care and maintenance going forward. The directors of the Company are assessing the impact on Rambler Metals and Mining plc and will provide further updates in due course.
