The company said that re-processing and re-crushing of the harder samples has increased the average overall grade to 134cpht the resource grade previously calculated at 120cpht.
Stellar Diamonds chief executive Karl Smithson said that the new average grade of 134cpht is already 12% higher than the previously calculated resource grade of 120cpht, before any reprocessing of the sample material, which it expects would further increase the grade.
"We anticipate that these increased grades will enhance the project’s global resource and economics, where the independent JORC resource currently stands at 1.1milllion carats at a grade of 120 cpht for just one of four kimberlite dykes within the licence area," added Smithson.
The Sample-10 was collected from an area of the kimberlite that was highly decomposed and was extracted by means of an excavator and has reported 201cpht, higher than other samples.
The company has processed a total of 1,271 ton of kimberlite and country rock at the DMS plant, yielding 730.14 carats of +1mm stones at a diluted grade of 57.44cpht.
"We expect to conclude our bulk sampling in June 2014 when a 1,000 carat parcel will be available for diamond value modelling as part of a definitive feasibility study, due for 2015. In the meantime, following our recent fundraise of £1.85 million, we look forward to advancing our Baoulé kimberlite pipe project, located in the prolific diamond region of Aredor in southeast Guinea, to trial mining in 2014," explained Smithson.
