    LONDON: 6 October 2008
    Firestone Diamonds plc, ("Firestone" or "the Company"), the AIM-quoted diamond mining and exploration company (ticker: AIM:FDI), today
announces an update on evaluation work at its BK11, BK16 and  Tsabong projects in Botswana.  

    HIGHLIGHTS
    BK11
    *     Drilling and bulk sampling ahead of schedule; results expected Q4 2008
    *     New diamond recovery facility constructed in Gaborone
    *     Pilot plant construction on schedule
    *     Significant progress made with scoping study
    *     Mine development decision may be advanced from Q4 2009 to Q1 2009, with possible commencement of production in 2010

    BK16
    *     Drilling and bulk sampling to commence ahead of schedule in October 2008
    *     Results expected Q1 2009

    Tsabong
    *     Bulk sample plant modifications completed on schedule in August 2008
    *     Diamonds recovered from MK1 tailings audit; all tailings now being reprocessed
    *     First macrodiamonds recovered from MK38; microdiamond analysis indicates potential grade of 25-30 cpht
    *     LDD drilling completed on 4 other kimberlites
    *     Work continues on other 79 kimberlites in the field

    Philip Kenny, CEO of Firestone Diamonds, commented: "We have made excellent progress in Botswana over the past three months. In
particular, we continue to be excited about BK11, where we believe we are close to confirming its economic potential. Our primary focus in
the coming months is to complete evaluation work on BK11 as soon as possible, with the objective of accelerating a mine development decision
to early 2009.  Work at Tsabong is progressing well and we continue to believe that the prospects for identifying economic kimberlites in
the area are good."

    BK11
    Substantial progress has been made at the BK11 kimberlite in the Orapa area, from which very good bulk sample results were reported in
June 2008.  BK11 is situated approximately 20 kilometres south east of Debswana's Orapa Mine and 5 kilometres north east of African
Diamonds' AK6 kimberlite.  Follow up drilling and bulk sampling is ahead of schedule.  Since July 2008 fourteen core holes have been drilled
for approximately 1,700 metres, with four holes remaining to be drilled.  Approximately 1,000 tonnes of kimberlite will be recovered from
large diameter drill ("LDD") drilling, with four 36 inch LDD holes completed and two holes remaining to be drilled.

    Material from the LDD holes is currently being transported to the Company's bulk sample plant ("BSP") at Tsabong for processing.  A new
diamond recovery facility has also been constructed at the Company's offices in Gaborone and diamond concentrate from BK11 and other
kimberlites will be transported from the BSP to this facility for sorting.  Bulk sampling results are expected to be available in Q4 2008,
and an independent valuation of diamonds recovered will be undertaken in Q1 2009.  Work on the new BK11 pilot plant, which is being
relocated to the Orapa area from the Company's Avontuur Mine in South Africa, is on schedule and the plant is expected to be operational in
the first half of 2009.

    Significant progress has been made on the scoping study for the development of a new mining operation to exploit BK11 and other
kimberlites in the Orapa area.  The Company is now evaluating the feasibility, subject to the results of the next stage of bulk sampling, of
accelerating a development decision on BK11 from Q4 2009 to Q1 2009, which could allow first production from BK11 to commence in 2010 with
an initial capacity of 1 million tonnes per annum.

    BK16
    The Company plans to carry out approximately 2,000 metres of core and 800 metres of LDD drilling on BK16, which is located 20 kilometres
from BK11. This work is scheduled to commence ahead of schedule in October 2008 once drilling on BK11 has been completed. Results are
expected to be available in Q1 2009.  

    Tsabong 
    In June 2008 the Company announced that it planned to modify the BSP in order to enable it to process material with high clay and zircon
content, such as from the MK1 kimberlite.  Since June, independent audits have been undertaken on samples of tailings from MK1. These audits
resulted in the recovery of nine macrodiamonds and confirmed that the BSP was not recovering all diamonds from the material being processed.
 The necessary modifications were completed on schedule in August 2008 and the BSP is now fully operational.  Approximately 36 tonnes of
tailings from MK1 are currently being reprocessed and results are expected to be available in Q4 2008.  

    A total of 55 microdiamonds have been recovered from a 214 kg core sample taken from the MK38 kimberlite.  Analysis of the size
frequency distribution of the microdiamonds indicates a potential macrodiamond grade of 25 to 30 carats per hundred tonnes. It should be
noted that this is a preliminary estimate, as between 200-400 microdiamonds are typically required to provide grade estimates with the
necessary levels of confidence.  A 60 tonne LDD sample is currently being processed, with three macrodiamonds recovered to date.  Bigger LDD
sampling is planned for MK38. 

    LDD drilling has been completed on four other Tsabong kimberlites. This material has been processed through the BSP and the concentrate
is in Gaborone awaiting sorting.  Work is continuing on evaluation of the 79 other kimberlites in the field and exploration for new
kimberlites.
