Stellar starts commissioning of Guinea’s Baoulé diamond processing plant, plans trial mining for October

12 september 2014
Stellar Diamonds said that the commissioning testing of its 100tph dense medium separation (DMS) plant at the Baoulé kimberlite project in Guinea has commenced ahead of trial mining targeted for next month.
The London listed diamond development company said in a statement emailed to Rough & Polished that waste stripping and ore extraction for stockpiling had also commenced with an objective to process at least 100,000 tonnes for diamond grade and value estimation.
“I am delighted that our team at Baoulé is continuing to deliver on schedule resulting in our processing plant now being fully constructed ahead of imminent trial mining,” said company chief executive
Karl Smithson.
“Commissioning is underway to establish the optimal operating parameters for the 100tph plant, after which the first kimberlite ore will be processed”.
He said the processing of a very large sample would not only establish the diamond grades and values, but also determine the presence of any large stones for which the Aredor region of Guinea was world renowned.
During this process any diamonds produced from trial mining would be sold to generate cash flow for the company, said Smithson.
Stellar had over the past three months relocated its processing plants and earth moving machines from the Mandala alluvial mine and Droujba kimberlite project in Guinea to the Baoulé site.
These had been re-constructed to establish an integrated kimberlite processing plant that can process both weathered and fresh kimberlite material from the 5 hectare kimberlite pipe.
The Baoulé kimberlite pipe was discovered in 1999.
A geological database showed that the pipe was delineated to 5 hectares in size and drilled to a maximum depth of 190m by a previous operator, but remains open at depth.
In-house modelling by Stellar of previous drilling over the pipe suggests a target of over 22 million tonnes to a depth of 300m, which, at the DMS generated grade of 13cpht, would suggest a target of 3 million carats; increasing to 6.5 million carats using the average microdiamond grade of 30cpht.
Meanwhile, Stellar said the Baoulé project had been unaffected by the Ebola virus and operations were continuing as normal.
