This suspension is effective immediately. As a result, the 15% export duty on precious gemstones will no longer apply to the Zambian emeralds mined by Kagem Mining Limited ("Kagem") which is 75% owned by Gemfields and 25% owned by the Zambian Government's Industrial Development Corporation. Sean Gilbertson, CEO of Gemfields, said: "We express our sincere thanks to President Hakainde Hichilema's government for their prompt and impressive action in addressing the 15% export duty on precious gemstones. The Zambian emerald sector has delivered phenomenal growth over the last 16 years and is today – by a significant margin –the world's largest emerald exporter. The government's collaborative approach and decisive action are clear demonstrations of its intent to deliver growth and jobs for Zambia and this step puts our industry back on track to continue that trajectory." -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").
