The single lot of beryl (of 5 million carats) was unsold. The specific auction mix and the quality of the lots offered at each auction vary in characteristics such as size, colour and clarity on account of variations in mined production and market demand. Therefore, the results of each auction are not directly comparable. Adrian Banks, Gemfields’ Managing Director of Product & Sales, commented: “The results announced today confirm once again that 2022 is the strongest year on record for Zambian emeralds mined at the Kagem emerald mine. Kagem’s year-to-date auction revenues now stand at USD 118 million, a notable figure when compared with the full-year record set in 2021 of USD 92 million. As with all Gemfields auctions of Kagem emeralds, these revenues are repatriated in full to Kagem in Zambia, meaning that Zambia sees the full value of its emerald resources flowing home. We thank and congratulate our hard-working teams, the government of Zambia (which owns 25% of Kagem) and of course our clients for their ongoing support in building one of the most sparkling sectors in African natural resources.” -ENDS- Gemfields Group Limited Page 2 of 4 Further information on Gemfields Group Limited can be found at: GEMFIELDSGROUP.COM To join our investor mailing list, contact us on: companysecretary@gemfields.com For any press enquiries please contact us on: gemfields@camarco.co.uk ENQUIRIES GEMFIELDS Sean Gilbertson / David Lovett T: +44(0) 20 7518 3400 SPONSOR (JSE) Investec Bank Limited SEDIBELO SALE PROCESS Liberum Nehal Patel: T: +44(0) 20 3100 2222 NOMINATED ADVISER finnCap (AIM) & JOINT BROKER Christopher Raggett / Tim Redfern / Edward Whiley T: +44(0) 20 7220 0500 JOINT BROKER Liberum Scott Mathieson / Kane Collings T: +44(0) 20 3100 2222 FINANCIAL PR/ IR Camarco Gordon Poole / Emily Hall T: +44(0) 20 3757 4980 ADDITIONAL INFORMATION ON GEMFIELDS Gemfields is a world-leading miner of responsible coloured gemstones.
