Results of first diamond sales

LONDON: 15 December, 2010

Firestone Diamonds plc, ("Firestone" or "the Company"), the AIM-quoted diamond mining and exploration company (ticker: AIM:FDI), is pleased to announce the successful completion of its first diamond tender held at the Company's new sales office at Diamond Technology Park in Gaborone, Botswana.

HIGHLIGHTS

Philip Kenny, CEO of Firestone Diamonds, commented: "The successful completion of our first tender is a major milestone for Firestone and marks the completion of our transition into one of only three listed junior kimberlite producers worldwide. We are very pleased that the prices achieved for both Liqhobong and BK11 production were higher than expected, and we believe that further price increases will be achieved for production from both of these mines in 2011."

The Company has completed the first sale of diamonds from the Company's BK11 Mine in Botswana and Liqhobong Mine in Lesotho. A total of 14,673 carats were sold by tender at the Company's sales office at Diamond Technology Park in Gaborone, Botswana, for gross proceeds of $1,611,817. The tender ran from 29 November to 9 December 2010, and was attended by more than 30 diamond buyers from Belgium, Israel, India, Russia and Southern Africa.

Liqhobong

A total of 12,510 carats from the Main Pipe at Liqhobong were sold on behalf of the Company's 75% owned subsidiary, Liqhobong Mining Development Co. (Pty) Ltd, for $1,228,625. The average price achieved of $98/carat is 14% higher than the most recent valuation of $86/ carat. It should be noted that the Liqhobong parcel included 1,745 carats of boart (industrial diamonds). This is not considered to be representative of run of mine production, which is expected to contain a lower proportion of boart. The average price of the Liqhobong parcel increases to $113/carat when the boart is excluded. It should also be noted that there were no special or fancy coloured stones in the parcel sold, whilst the Main Pipe at Liqhobong is known to produce such goods. As a result, the Company expects that prices achieved for Liqhobong production in 2011 will be in excess of $100/carat.

The Company recently announced a £13 million financing that will allow production to recommence at the Main Pipe in Q1 2011, with production capacity to be tripled to 1.3 million tonnes per annum by Q4 2011. 

BK11

A total of 2,162 carats from BK11 were sold on behalf of the Company's 90% owned subsidiary, Monak Venture (Pty) Limited, for $383,191. The average price achieved of $177/carat is in line with the most recent valuation of $175/ carat for diamonds from the west side of BK11, where current mining operations are focused. It should be noted that the majority of the diamonds sold were recovered from the treatment of low grade overburden, and are of lower quality and smaller average size compared to the run of mine production expected from the higher grade kimberlite that will be mined in 2011. The BK11 production plant is expected to be operational at the target production capacity of 1.5 million tonnes per annum by January 2011.

Future diamond sales

The Company plans to hold nine tenders in 2011. The average size of the BK11 tenders is expected to be approximately 12,000 carats, and the average size of the Liqhobong tenders is expected to start at approximately 15,000 carats, increasing to 50,000 carats by Q4 2011.
