Diamond mining company Lucara Diamond on Monday announced the resignation of CFO Zara Boldt and VP of technical services John Armstrong.
Boldt will step down with effect from December 29, and Armstrong will resign on December 1. The company did not name successors for either Boldt or Armstrong.
Lucara, which owns the Karowe mine in Botswana, in August reappointed William Lamb as CEO, when Eira Thomas resigned.
