Diamcor no longer reliant on Eskom power

14 july 2023

Diamcor Mining has completed the modification of its existing generator systems at its Krone-Endora at Venetia diamond mine project in South Africa.

This, according to the diamond company, is intended to address the detrimental effects on processing rates and diamond recoveries that have been observed recently as a result of an increase in power outages in South Africa, as well as associated revenues.

Diamcor said it is now possible to process materials as needed without relying on the Eskom-supplied power grid.

“The increased frequency and uncertainty of power supply at the project was significantly limiting our ability to process material and generate diamond recoveries and associated revenues in recent months and required a solution to eliminate these issues moving forward,” said company chief executive Dean Taylor.

“Overcoming these issues is a significant milestone which allows us to now aggressively resume advancing our ongoing trial mining efforts, processing volumes, and the bulk-sampling efforts on the greater areas of the project."

He said the existing generator systems were initially installed to address short-term power outages.

However, the increased frequency of daily power outages experienced over the past few quarters forced the company to reconfigure its power systems.
