Completion of disposal of 50% interest in Kariba Minerals Limited GEMFIELDS GROUP 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") Completion of disposal of 50% interest in Kariba Minerals Limited On 10 December 2018, Gemfields announced that Gemfields Canada Inc. (a 100% subsidiary of Gemfields) had agreed to sell its 50% stake in Kariba Minerals Ltd (“Kariba”), the Zambian amethyst mine, to ZCCM Investments Holdings plc (“ZCCM”). That transaction was subject to assorted administrative steps and regulatory approvals, including from the Zambian Competition and Consumer Protection Commission and the Zambian Ministry of Mines. Under the terms of the transaction, Gemfields would receive USD 2.5 million in consideration for the disposal of its shares and would discharge all outstanding sums owed by Kariba to the Company. Gemfields’ decision to dispose of its stake in Kariba was driven by the Company’s strategy of focusing on emeralds rubies and sapphires. Gemfields confirms that the transaction has completed and that it has received net consideration USD 2.375 million after deduction of the applicable property transfer taxes in Zambia.
