The results show an average yield of 56 carats per hundred tonne (Cpht) of hi-grade diamonds, slightly above the average grade of Sierra Leone, which, according to the comprehensive report undertaken in the 1970s by PK Hall, shows an average of approximately 50 Cpht.

The results go on to show equally impressive data in relation to the incidence of gold with sampling taken from a total of 270 tonnes of gravel showing 62 grams per hundred tonne at an excellent purity rate of 96.4%.

Tom Tucker, CEO of GGSM Mining Sierra Leone, comments, “These preliminary results clearly show that GGSM has an extremely bright and promising future. With such economically significant quantities of both high quality gold and diamonds we will begin the planned rapid expansion of our current mining operations into the surrounding chiefdoms with whom I’ve established very strong relations over recent years.”

With diamond prices continuing to increase, GGSM’s management are busy securing the necessary distribution deals with the major players in the international diamond markets to help to secure significant revenues into the company once production begins.

According to diamondintelligence.com, the average price per carat value during the first quarter of 2010 jumped 72 percent to USD $1,753 from USD $1,017 per carat in the first quarter of 2009. Subsequently, an average price of USD $2,002 per carat has been observed.
