Results of tender

A total of 24,109 carats was available for sale, an increase of 69% from the last diamond sale in July 2011.  Approximately 3,395 carats were sold for gross proceeds of $863,037.  A further 20,000 carats, principally comprising smaller diamonds, were available for sale, but reserve prices for these diamonds were not achieved at the tender and they were withdrawn.  The diamonds sold included 1,846 carats from Liqhobong, which sold for an average of $231/carat, and 1,549 carats from BK11, which sold for an average of $282/carat.  Subsequent to the closing of the tender the Company has received a number of enquiries in relation to the withdrawn diamonds, but these will be held until the next diamond sale.

Rough diamond market

The results of the diamond sale reflect a drop in overall rough diamond prices of approximately 15 to 20% since the beginning of August 2011 and significant volatility in prices in selected categories of diamonds.  This has been primarily driven by recent uncertainty in international financial markets.

Rough diamond prices increased approximately 40% in the first half of 2011 driven by significant growth in demand from China and India.  With continued growth expected in demand from China and India and insufficient new production to address the current shortfall in supply, the prospects for rough diamond prices remain positive.

Future diamond sales

The Company expects that stability will return to the rough diamond market later in 2011 and that the shortfall in rough diamond supply will limit any further significant decreases in rough diamond prices.  Following the completion of the ?13.5 million financing announced in July 2011, the Company's cash position remains secure, and the Company has the ability to withhold any production that does not achieve reserve prices until stability returns to the rough diamond market later in 2011 or in early 2012.  The next diamond sale will be held in Q4 2011, with the timing to be selected on the basis of financial market and rough diamond market conditions.

Tim Wilkes, CEO of Firestone Diamonds, commented: "We have continued to make significant progress at both Liqhobong and BK11, with a 69% increase in production available for sale from the last tender in July 2011.  Although demand for smaller diamonds has decreased, it has remained firm for larger, better quality diamonds, and we are confident that we will see increased demand for our full range of production later in 2011."
