Ian Harebottle, CEO of Gemfields, commented:

"Gemfields is pleased to report on another healthy quarter and a strong annual production result for the world-class Kagem emerald mine. Emerald and beryl production increased 42% year-on-year and were further supported by better grades and lower unit costs. We achieved record revenues from our most recent auction of lower quality rough emerald and beryl, despite a small drop in the average per carat price achieved. The outcome of our auction of higher quality rough emeralds, which took place after the end of the financial year, yielded record per carat prices and is clearly indicative of the continued increase in demand for consistently supplied high quality coloured gemstones.

We continue to seek guidance and to interact with the Government of Zambia - our fellow shareholders in Kagem - with respect to possible restrictions on the ability of Gemfields and Kagem to freely choose the locations of its auctions and thereby our ability to sustain the current levels of growth in demand for Zambia's magnificent and long undervalued gems. In that light, and in order to further a broader understanding of the emerald sector, we were pleased to sponsor the first-of-its-kind '2013 Zambian Emerald Summit' in Lusaka at the end of May and to facilitate highly interactive discussion among some of the global emerald sectors leading stakeholders. While the two auctions held in Lusaka this year have certainly been successful, the key question of course remains what they would have generated had they been held abroad (where competing and undermining sources of supply, frequently illegal, are not readily available to our customers) and their potential impact on the long term growth of this sector".

Production Update

The 75%-owned Kagem emerald mine is presently Gemfields' only operating emerald mine and is the single largest emerald mine in the world. The key production parameters by quarter are summarised below:

* Note: With effect from July 2011, Gemfields adopted a new accounting policy whereby all waste moving costs are capitalised and are then subsequently amortised when the ore corresponding to that waste is mined. As of 30 June 2013, approximately USD 30.3 million of waste moving costs have been capitalised and will be amortised later when the associated ore is mined.

The quarter to 30 June 2013 produced 8.9 million carats at a grade of 322 carats per tonne of ore and a unit production cost of USD 0.50 per carat (excluding capitalised waste moving costs).

The previously announced large-scale waste movement programme to open up new areas for future ore production ran until 30 June 2013 with over 2.5 million tonnes of rock having been moved in the quarter. Cash rock handling unit costs were USD 3.60 per tonne in the current quarter (compared to USD 3.55 in the quarter to 30 June 2012).

Gemfields' trial underground mining project achieved 106.7 metres of horizontal advance during the quarter ending 30 June 2013 (versus 66 metres in the quarter ending 31 March 2013). The total linear development for the financial year ending 30 June 2013 is 300.4 metres (versus 283 meters for the previous financial year). This quarter's work has focussed on cross-cut development and the initiation of the second stope according to enhanced design criteria. A total of 1,108 tonnes of ore was produced during the quarter (versus 998 tonnes in the prior quarter). Approximately 22,025 carats were produced by the underground operation in the quarter (versus 17,835 carats in the prior quarter). The grade for this financial year is 77.5 carats per tonne, and the grade for the project is 80.1 carats per tonne to date.

Illegal mining activity within the boundaries of the Kagem mining licence is not yet fully resolved and Gemfields continues to work with key ministries to alleviate this challenge.

Auction Update

While there is presently no law in Zambia that prohibits the export of emeralds for auction purposes, Gemfields was asked by the Zambian Ministry of Mines, Energy and Water Development to host its two most recent auctions within Zambia. These took place in the capital, Lusaka, from 15-19 April (lower quality) and 15-19 July (higher quality).

The April 2013 auction, of predominantly lower quality rough emerald and beryl, realised record revenues of USD 15.2 million for lower quality auctions, underpinned by the volume offered. A 7% decline in average per carat prices reversed the historic growth trajectory. Of the 17.3 million carats offered, 36% (6.3 million carats) was sold. Quality-for-quality per carat prices showed a mixed performance, with higher qualities clearly favoured. The historic lower quality auction results are summarised below:

 * A larger volume of material was placed on offer in March 2010 following Gemfields extensive inventory building exercise during 2008 and 2009.

The July 2013 auction, of predominantly higher quality rough emerald and beryl (and which took place after the quarter end) saw all of the 583,448 million carats placed on offer being sold, generating the second highest aggregate revenues achieved to date (of USD 31.5 million). The auction yielded an overall average of USD 54.00 per carat, the highest unit value achieved at any auction, and representing a 26% increase over the previous high of USD 42.71 per carat (achieved in the July 2011 Singapore auction). The historic higher quality auction results are summarised below:

2013 Zambian Emerald Summit

In order to facilitate dialogue between key stakeholders within the emerald industry, Gemfields hosted the '2013 Zambian Emerald Summit' in Lusaka, Zambia on 30 and 31 May 2013. The summit, comprising presentations, panel discussions and Q&A sessions considered, inter alia, how the Zambian emerald sector might best be developed into a world leader whilst ensuring that the relevant revenues and profits accrue within Zambia. Key industry stakeholders in the region were been invited to participate and the event was well received.

Mozambique Ruby Update

Bulk-sampling operations at the Mozambican ruby project owned by Montepuez Ruby Mining Lda (in which Gemfields has a 75% interest) are progressing with recent results showing encouraging ore recovery. The core infrastructure required for operations is largely established with primary stage mining and processing equipment on site and operational. A pilot and semi-mobile ore processing plant continues to test the characteristics of the ore with adjustments being made to the plant to improve efficiencies in the ore washing and cleaning process. A sizeable increase in processing capacity has been achieved. Gemfields expects the first auction of rough rubies to take place in the first calendar quarter of 2014.

A bespoke ruby grading and sorting framework has been developed and various downstream ruby treatment processes are being investigated. A significant security presence has reduced illegal mining on the licence area.

Fabergé

Fabergé is one of the world's most recognised luxury brand names, underscored by a well-documented and globally recognised heritage. The acquisition of 100% of Fabergé Limited by Gemfields was formally completed on 28 January 2013. The integration of Fabergé into the Gemfields family is well underway. The acquisition enables Gemfields to take its vision for coloured gemstones to the next level, harnessing the Fabergé name to boost the international presence and perception of coloured gemstones and advance the "mine and market" vision. The first steps in this approach were taken in April at BaselWorld 2013. In the financial year ending 30 June 2013, Fabergé sold a record number of products.

Cash Balances

At 30 June 2013, Gemfields had cash of USD 11.6 million (and total debt outstanding of USD 11.6 million) with Kagem having generated an additional USD 31.5 million in cash soon after the close of the quarter under review and as proceeds from the successful high quality emerald auction held in Lusaka, Zambia in July 2013.
