[1]Recovery of a bulk sample from Stornoway Diamond’s Renard diamond project is complete and valuation is scheduled to take place shortly in Antwerp.
In total, 962.8 carats of diamonds larger than a +1 DTC size sieve were recovered from 5080.8 dry tonnes from Renard 65.
As previously reported, a 9.78-carat unbroken white octahedral gem was discovered during ongoing processing of the bulk sample at the company’s North Vancouver diamond recovery facility. Preliminary valuation puts the diamond at $7000 per carat. The next largest stone in the sample is 6.41 carats and also a white octahedral gem, with a preliminary valuation of $4700 per carat.
Crews extracted the current bulk sample from a site that is known to represent a lower grade portion of the kimberlite, but which is easily accessible from the surface.
