Emerald Auction

A total of 37 companies placed bids in the first Gemfields auction of the current financial year. The auction followed 7 successive emerald auctions held in Lusaka, and marked the return of Zambian emerald auctions to the broader international market.
The auction saw 0.6 million carats of higher quality emerald extracted from Kagem placed on offer, with 18 of the 19 lots offered being sold, generating auction revenues of USD 34.7 million. The auction realised an overall average value of USD 58.42 per carat, the third highest figure on record.
The Company's 19 auctions of emeralds and beryl mined at Kagem since July 2009 have generated
USD 360 million in total revenues.
The results of the five most recent higher quality Kagem auctions are summarised in the table below. Additional historic information regarding higher quality auctions can be found in the 'Further Information' section of this announcement.

The specific auction mix and the exact quality of the lots offered at each auction vary in characteristics such as size, colour and clarity on account of variations in mined production and market demand. Each auction naturally contains a degree of variation in overall quality composition, which is typically reflected in the average per carat sales value.

Amethyst Auction

This auction of rough amethyst from Kariba Minerals Ltd (in which Gemfields has a 50% interest) was the first to be held in Singapore. Gemfields has hosted only two prior rough amethyst auctions which took place in Jaipur in March 2011 and in Lusaka in February 2015.
The Singapore amethyst auction saw 11.0 million carats of higher quality amethyst extracted from
Kariba placed on offer, with 11 of the 16 lots offered being sold, generating auction revenues of USD
0.44 million from the 10.1 million carats sold. The amethyst auction realised an overall average value of 4.32 US cents per carat (an increase of 144% compared to the 1.77 US cents per carat realised in the February 2015 auction).

Next Auction

Gemfields' next auction is presently expected to take place in November 2015, comprised predominantly of lower quality emerald and beryl.
Ian Harebottle, CEO of Gemfields, commented:

"Our Singapore auction has delivered another very strong result for our Kagem emeralds. With 98% of the emeralds sold, it is very pleasing indeed to see Zambian emeralds continuing to enjoy such firm demand, aided by our return to running an auction in Singapore. Despite severely depressed global commodity prices, well-documented difficulties in the diamond sector and recent volatility across international financial markets, emerald prices remain as robust as ever. The counter-cyclicality often associated with precious gemstones, and their reputation as a store of value in turbulent times, have shone through. In addition it is pleasing to see the prices received for amethyst increase markedly since the last auction in February. I'm delighted that these results underscore the intended vision and trajectory for coloured gemstones, and for Gemfields.

Kagem is a partnership between the Zambian Government and Gemfields, and we'd like to thank the Government for their vision and support in internationalising the Zambian emerald industry and for supporting an 'international auction circuit' that will see Lusaka remain one of the key hubs for hosting emerald auctions in order to ensure we reach an expanded client base.
