BK11 update

LONDON: 30 June, 2010

Firestone Diamonds plc, ("Firestone" or "the Company"), the AIM-quoted diamond mining and exploration company (ticker: AIM:FDI), is pleased to announce an update on development work and production plans at its BK11 kimberlite in Botswana.

HIGHLIGHTS

Philip Kenny, CEO of Firestone Diamonds, commented: "We have made significant progress at BK11 since April. The imminent expected commencement of production at BK11 is a major milestone for the Company as is it will make Firestone one of only three kimberlite producers worldwide outside of the major mining companies. The combination of cash flow from production at BK11, an extensive portfolio of kimberlites in the Orapa and Tsabong kimberlite fields and exciting toll treatment opportunities positions Firestone very well for significant growth in Botswana and with the substantial shortfall in rough diamond supply projected in the coming years we are confident about Firestone's future prospects. We look forward to further updating our shareholders very soon once the mining licence has been granted and production has commenced."

Background

Development work has been under way at BK11 since the successful completion of the final phase of evaluation work in December 2009. A mining licence application was completed and submitted to the Ministry of Minerals, Energy & Water Resources (the "Ministry") during Q1 2010 and in April 2010 the Company raised £9.45 million, of which approximately £4.5 million was to cover the final capital costs relating to the BK11 production plant and for pre-stripping of near-surface low grade kimberlite.

Production plant

Work on Phase 1 of the production plant, which has a capacity of approximately 650,000 tonnes per annum, has been completed and the plant is ready to commence production as soon as the mining licence is issued. Work on Phase 2 of the production plant, which will increase production capacity to 1,500,000 tonnes per annum, is on target for completion as originally scheduled in Q3 2010. 

Mining licence

Since April 2010 the Company has been in discussions with the Department of Mines ("DoM"), which is the part of the Ministry that is responsible for assessing mining licence applications. The Company has provided additional information requested by the DoM and there are no further matters outstanding from the Company in relation to the BK11 mine development plan and mining licence application. The Company expects the mining licence to be issued imminently.
