Results - Singapore Rough Ruby Auction

19 December 2016

Gemfields plc (AIM: GEM) is pleased to announce the results of its auction of rough ruby extracted by Montepuez Ruby Mining Limitada (which is 75% owned by Gemfields and 25% by local partner Mwiriti Limitada) from the Montepuez ruby deposit ("Montepuez") in Mozambique. The auction was held in Singapore from the 12th to the 16th of December 2016 and was the first ruby auction of this financial year.

Highlights

· Auction revenues of USD 30.4 million (the fourth highest ruby auction result to date);

· Average realised price of USD 27.79 per carat;

· 1,094,406 carats sold (80% by weight or 85% by market value) out of the total of 1,372,145 carats offered; and

· Seven Montepuez auctions held since June 2014 have generated USD 225.7 million in aggregate revenues.

Montepuez Ruby Auction

Gemfields' seventh auction of rough rubies and corundum from Montepuez saw 39 companies placing bids. The auction offered high and commercial grade rough rubies in both untreated and treated form. All treated lots were offered using industry accepted treatment techniques and on a fully disclosed basis.

The quality and quantity of the goods placed on offer was developed in response to market feedback which showed growing demand for rough rubies suited to the production of high quality jewellery as well as larger volume production runs, thereby allowing a broad cross-section of product to be placed on offer. The improved reliability of supply and the consistency of the Gemfields grading system continues to be well received by the Company's clients as it facilitates reduced risk, improved manufacturing efficiencies and an increased ability to meet consumer demand.

The auction generated total revenues of USD 30.4 million at an average realised price ofUSD 27.79 per carat. Given the quality mix offered at this auction comprised a blend of varying qualities and sizes of material, a direct top-line comparison with the results of previous auctions is not feasible. On a quality for quality basis however, the per carat prices achieved continue to indicate good overall global demand when compared to previous auctions.

The auction results, which saw 58 of the 76 lots offered being sold, provided a high level of support for the Company's understanding of the current market demand profile, which was further supported by customer feedback received during the auction.

The results of the five most recent Montepuez auctions held to date are summarised below (and the prior auction results can be found in the 'further information' section at the end of this announcement):

The proceeds of this auction will be repatriated to Montepuez Ruby Mining Limitada in Mozambique, with the royalties due to the Government of Mozambique being paid on the full sales price achieved at the auction.

Gemfields' aggregate consolidated revenues from all rough gemstone auctions for the financial year to date stands at approximately USD 41.1 million. Gemfields' auctions of rough gemstones from the Kagem emerald mine in Zambia and from the Montepuez ruby deposit in Mozambique have now generated USD 662.9 million in total revenues.

Ian Harebottle, CEO of Gemfields, commented:

"We are very pleased with the results of Gemfields' seventh Montepuez ruby auction despite some of our customers being unable to attend while they adjust to the regional demonetisation policy changes they've experienced over the past few weeks.

The prices achieved at this auction, combined with the high percentage of the value sold, fully support our view of ongoing solid demand for responsibly sourced Mozambican rubies across key markets and categories. The recent prices obtained for fine cut-and-polished Mozambican rubies by international auction houses further underscore the exciting trajectory for rubies from Mozambique.

As always, we thank our customers, our business partners, our host government and give credit to every member of our devoted and hard-working global team."
