As of 31 March2012, approximately USD 8.8 million of waste moving costs have been capitalisedand will be amortised later when the associated ore is mined.

The quarter ending 31 March 2012 produced 4.9 million carats at a grade of 236 carats per tonne of ore and a unit cost of USD 0.85 per carat (excluding capitalised waste moving costs).

Kagem's previously announced large-scale waste mining programme to open newareas for future ore production is ongoing, with over 5.9 million tonnes ofrock having been moved in the last three quarters. While the stripping ratiowill continue to increase in the near term as areas of overburden and waste aremined, management expects an overall increase in operating efficiencies andperformance in the medium to longer term as Kagem is able to mine both wasteand ore more efficiently.

This present focus on waste mining, combined with external factors, has had anegative impact on gemstone production in the short term, however, productionis improving quarter by quarter and is expected to continue to increase in

thecoming months.

The harder rock types currently being mined resulted in approximately 0.7 million tonnes of waste being mined by the contractor during the quarter (compared to 1.1 million tonnes in the previous quarter) with cash rock handling costs increasing to USD 3.73 per tonne (compared to USD 3.21 in prior quarter).

Kagem's key annual production parameters are summarised below:

A focus on production mining has seen an increase in the number ofcarats produced from the same contact areas. Some 141,315 carats were producedin the quarter ending 31 March 2012 (versus 61,077 carats in the priorquarter), improving the underground project's overall grade to 77.9 carats

pertonne.

Kagem has entered into a USD 9.3 million debt facility at an interest rate of 3month LIBOR plus 4.75% with Barclays Bank Zambia plc. The loan will be drawndown within one year and is repayable over a period of 36 months in monthlyinstalments from the date of first drawdown. Security for this loan comprises acorporate guarantee from Gemfields plc, a charge over the assets of KagemMining Limited (excluding the mining licences) and a cash deposit pledge. Thefacility will be used to pay the contractor undertaking the removal of waste inthe Chama section of the Kagem mine and is an initial step towards Kagem MiningLtd becoming a fully independent and self-funding operation. The initialdrawdown of USD 3.0 million will take place in May 2012 and is in part designedto strengthen Kagem's credit rating for future growth.

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.

Cash Balances

As of 31 March 2012, Gemfields had USD 46.6 million in cash and receivables.

Ian Harebottle, CEO of Gemfields, commented:

"As demand for ethical coloured gemstones continues to increase across allmarkets we look forward to our next emerald auction, of lower quality rough,which takes place in Jaipur in June 2012. Gemfields' healthy cash position hassupported the Company's decision to actively pursue the development of otherassets in its portfolio and to increase the scale of operations at its Kagemmine. The recently finalised loan facility will further support Kagem's abilityto operate as a stand-alone company where operational performance will continueto improve post the current high-wall pushback with increased production outputanticipated in the last quarter of this financial year and well into the nextfinancial year."
