These unaudited figures have been produced on a monthly basis for Gemfields' 75%-owned Kagem emerald mine, its 75%-owned Montepuez ruby mine and Fabergé, the iconic luxury brand. The full operational results and an excel spreadsheet of Gemfields' historic figures can be found on the Company's website at www.gemfieldsgroup.com/operational-update/. Highlights - Total auction revenues of USD 196 million for the year. - Net debt position of USD 80.5 million (before auction receivables of USD 33.9 million) at 31 December 2024 as Gemfields continues to fund MRM's second processing plant. - Construction of MRM's second processing plant remains materially on budget and on track for completion by the end of H1 2025 despite disruptions in Mozambique from October 2024 to mid-January 2025 with civil unrest following the contested presidential election. - MRM has been operating as usual since the start of 2025, following the events announced on 27 December 2024 and amid heightened illegal miner intrusions in the wake of the civil unrest. - Kagem has paused mining from the start of 2025 as previously announced, utilising its upgraded wash plant to process its significant stockpiles. - Emerald exports are, since 1 January 2025, paused while Zambia's reintroduced 15% export duty remains in place. Kagem anticipates that the duty may be revoked and allow a commercial-quality emerald auction to go ahead in Q1 2025. Commentary on the operational performance and financial results will be available in Gemfields' full year results and Annual Report due to be published on Thursday 27 March 2025. Shareholders are advised that all figures in this operational update are unaudited, in respect of which the directors assume full responsibility. -ENDS- Further information on Gemfields Group Limited can be found at: GEMFIELDSGROUP.COM To join our investor mailing list, please contact us on: ir@gemfields.com This announcement contains inside information for the purposes of Article 7 of the Market Abuse Regulation (EU) no. 596/2014 which forms part of domestic UK law pursuant to the European Union (withdrawal) act 2018 ("MAR") ENQUIRIES GEMFIELDS Sean Gilbertson / David Lovett / Ian Hughes ir@gemfields.com T: +44(0) 20 7518 3400 SPONSOR (JSE) Investec Bank Limited NOMINATED ADVISER Panmure Liberum (AIM) & BROKER Scott Mathieson / Amrit Mahbubani / John More T: +44(0) 20 3100 2222 PRESS ENQUIRES, GEMFIELDS Helena Choudhury / Albertina Namburete HEAD OFFICE, LONDON helena.choudhury@gemfields.com/ albertina.namburete@gemfields.com ADDITIONAL INFORMATION ON GEMFIELDS Gemfields is a world-leading responsible miner and marketer of coloured gemstones.
