Singapore Emerald Auction

10 June 2013

In its quarterly market update of 14 May 2013, Gemfields plc (AIM: GEM) advised that the next auction of higher quality rough emerald and beryl from the Kagem emerald mine was scheduled to take place in Singapore from 10-14 June 2013.

Gemfields today advises that the auction has been put on hold pending clarification from the Zambian Ministry of Mines, Energy and Water Development (the "Ministry") of proposed restrictions on certain forms of emerald exports.

At a press conference in Lusaka on Friday 5 April 2013, Yamfwa Mukanga, the Minister of Mines, Energy and Water Development addressed members of the media and distributed a press statement seemingly restraining the Kagem emerald mine (and other producers) from auctioning emeralds outside of Zambia. Kagem is 75% owned by Gemfields, with the other 25% belonging to the Government of the Republic of Zambia.

Gemfields is actively corresponding with the Ministry and hopes that solutions supporting the continued growth of Kagem and the wider Zambian emerald sector will be reached as soon as possible.

Ian Harebottle, CEO of Gemfields, commented:

"While there is presently no law in Zambia that prohibits the export of emeralds for auction purposes, we naturally wish to ensure that we work collaboratively with the Government of the Republic of Zambia, who are our fellow-shareholders in the world-class Kagem emerald mine. Figures recently released by the Zambian Revenue Authority show that Kagem pays approximately 80% of the gemstone sector's aggregate royalties and that, last year alone, Kagem paid about 40% of the total cumulative gemstone royalties collected in the seven-and-a-half years since 2006. As such, there is a strong incentive for all parties to ensure that the remarkable growth Kagem has enjoyed in recent years - and the benefits that this growth has provided for the wider Zambian gemstone sector - are not impeded."
