Stellar ups diamond grade, resource for Dyke-1 to 1.45 mln carats

01 december 2014

West Africa-focused Stellar Diamonds has recorded a 35 percent increase in the Joint Ore Reserves Committee (JORC) compliant inferred resource to 1.45 million carats for its wholly-owned Tongo kimberlite Dyke-1 project, in Sierra Leone.
It said in a statement emailed to Rough & Polished that the bulk sampling results had led to a 37 percent increase in average diamond grade to 165 carats per hundred tonnes.
Stellar chief executive Karl Smithson said the combination of high grades and high diamond values made this kimberlite one of the “highest value” kimberlites in the world in terms of in-situ value of dollar per tonne.
“Importantly further resource potential exists from three parallel kimberlite dykes which form part of the Tongo dyke swarm,” he said.
“This includes the 1km long Dyke-4 which has previously been bulk sampled and returned a diamond grade estimate of 110cpht and an estimated average diamond value of $140 per carat.”
Stellar said the project’s in situ kimberlite value was estimated at between $239/t and $324/t, with an in situ resource value of between $214-million and $290-million.
