Highlights – MRM Commercial-Quality Auction – September 2024 - Auction revenues of USD 2.3 million (2023's MRM Commercial-Quality Auction: USD 1.5 million) - All of the 5.7 million carats (1,130 kilograms) offered in 10 lots were sold (100%) - Average sales price of USD 0.41 per carat Adrian Banks, Gemfields' Managing Director of Product & Sales, commented: "We extend our gratitude to the auction participants who made this brief, three-day auction such an enjoyable event. The majority of the auction's offering consisted of corundum and sapphire, which are considered by-products of MRM. Despite the commercial nature of these goods, the auction saw strong attendance and robust demand. The significant volume of the lower-priced rough sold, will support the factories in the cutting centres of Chanthaburi, Thailand and Jaipur, India. We thank and congratulate the Government of Mozambique and our partners at Mwiriti - both of whom attended the auction - on what are very healthy results for material of this quality." The gemstones were extracted by Montepuez Ruby Mining Limitada in Mozambique ("MRM", which is 75% owned by Gemfields and 25% by Mwiriti Limitada). The proceeds of this auction will be fully repatriated to MRM in Mozambique, with all royalties due to the Government of the Republic of Mozambique being paid on the full sales prices achieved at the auction. -ENDS- Gemfields Group Limited, Royal Chambers, St Julian's Avenue, St Peter Port, GY1 4HP, Guernsey T +44 (0)1481 731 554 gemfieldsgroup.com Further information on Gemfields Group Limited can be found at: GEMFIELDSGROUP.COM To join our investor mailing list, contact us on: ir@gemfields.com For any press enquiries please contact us on: gemfields@camarco.co.uk 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").
