This morning, an attack attributed to insurgent activity has been reported at the neighbouring ruby mine belonging to Gemrock, which lies approximately 12km south-east of the operations of Montepuez Ruby Mining Limitada (“MRM”), in which Gemfields holds a 75% interest. Details of the attack are being verified. As a consequence, MRM has initiated the process of evacuating operational employees and contractors, and therefore mining operations at the site have ceased. Security personnel and Mozambique police force remain on site and Mozambique military are arriving on site. Gemfields and MRM hold the health and safety of their employees and contractors as their highest priority and remain in regular contact with government authorities. We will keep the market updated of further developments. -ENDS- Further information on Gemfields Group Limited can be found at: GEMFIELDSGROUP.COM Gemfields Group Limited, Royal Chambers, St Julian’s Avenue, St Peter Port, GY1 4HP, Guernsey T +44 (0)1481 731 554 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 ENQUIRIES GEMFIELDS Sean Gilbertson / David Lovett / Ian Hughes ir@gemfields.com T: +44(0) 20 7518 3400 SPONSOR (JSE) Investec Bank Limited 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.
