Stellar Diamonds describes latest Tongo drilling results as "excellent"
Stellar Diamonds (LON:STEL) chief executive Karl Smithson this morning described as “excellent” the results from bulk sampling on Dyke 1 of the Tongo kimberlite project in Sierra Leone.
The group also confirmed it is on track for a maiden resource statement by the end of this quarter.
The bulk sample grade was 121 carats per hundred tonnes with an average diamond value of US$185 per carat, while microdiamond analysis indicates “encouraging size distribution”.
Initial resource drilling of a 1.9 kilometre section of the 2.5 kilometre long Dyke 1 kimberlite was completed in December.
The remainder will be drilled during the next phase of resource definition.
Some 32 holes for 4,048 metres were drilled and kimberlite was intersected in 27 of the holes.
The deepest intersection of kimberlite was recorded at 202 metre vertical depth from surface and the kimberlite remains open at depth and along strike, the company said.
Chief executive Smithson added: "The drilling and bulk sampling of the high-grade 2.5km long Dyke 1 kimberlite has now been completed and has generated excellent results.
“With a diamond grade of 121 carats per hundred tons and diamond value of $185 per carat, the calculated in-situ value of the kimberlite is $224 per tonne.”
Independent consultants CAE Mining will compile the maiden Tongo resource statement for Dyke 1.
