Zambian Revenue Authority Search Warrants GEMFIELDS GROUP LIMITED (formerly Pallinghurst Resources Limited) (Incorporated in Guernsey) (Guernsey registration Number: 47656) (South African external company registration number 2009/012636/10) Share code on the BSX: GML.BH ISIN: GG00BG0KTL52 Share code on the JSE: GML ("Gemfields" or the "Company") Zambian Revenue Authority Search Warrants Gemfields advises that the Zambian Revenue Authority (“ZRA”) served two search warrants during an unannounced visit to Kagem Mining Limited (“Kagem”) on 16 August 2018. The two search warrants were issued in respect of Kagem Mining Limited and Limpopo Polygraphs CC (“LPCC”), a South African company conducting periodic polygraph testing at Kagem, and whose representative is presently on site at Kagem. The search warrants authorise ZRA to take wide-ranging documents and files including those allegedly “used by Kagem Mine Ltd / Limpopo Polygraphs CC to evade the payment of Value Added Tax, income tax, with-holding tax and other taxes”. Gemfields understands that the aggregate value of all work conducted to date by LPCC for Kagem is less than USD 7,500.00. Gemfields will provide further updates as pertinent information becomes available. Additional information on Gemfields Gemfields is a world leading supplier of responsibly sourced coloured gemstones.
