Sale of BK11 Asset - Extension of Option Period

Firestone Diamonds (AIM: FDI), a new diamond producer with operations focused in Lesotho, announces that, as provided for in the contractual agreements between the parties, the Group has agreed to extend the option period granted to Amulet Diamond Corporation ("Amulet") to purchase Firestone's BK11 asset until 31 December 2018.

BK11 is a diamond asset in Botswana, currently on care and maintenance. As previously announced, Amulet is funding the construction and operation of a bulk sampling plant at the BK11 mine during the option period to further assess the deposit. Amulet has made steady progress towards completing the bulk sampling plant but due to unforeseen equipment delivery delays, Amulet requested an extension to the option period which has been granted by Firestone.
