The recovery of all rough diamonds were incidental to the ongoing commissioning and testing exercises performed at the Krone-Endora at Venetia project and yielded an average price of $159 per carat.
An additional 2 050 ct of rough diamonds were recovered during the period and are being prepared for sale at upcoming tenders along with rough diamonds expected to be recovered in the current quarter.
Operational efforts during the first quarter focused on the completion, commissioning, and refinements of the upgrades and expansions to the project’s processing plant.
These included the installation of a large autonomous mill/wet scrubbing unit to enhance the liberation of all material and the expansion of the treatment plant’s feed bin capacity and conveyor structures to support added processing capacity.
It also included the installation of nuclear density measurement equipment to increase operational efficiencies and controls associated with the plant’s pre-concentrating pans, the installation of expanded tailings storage and automated conveyor loading systems and the installation and calibration of additional weightometer systems on various conveyor structures located throughout the project.
Diamcor said these project upgrades have achieved the desired goals of increasing the liberation of the conglomerated material in all size fractions, and enhanced the overall operational efficiency of the treatment plant.
The Company’s focus during the current quarter will now shift to increasing processing volumes, the size fractions of material being processed, with consideration for above larger material cut-off size, and a move towards advancing objectives consistent with the recommendations of the updated NI43-101 Technical Report filed by the company on 28 April 2015.
