Vancouver-headquartered Lucara Diamond Corp achieved strong operating results for the year ended December 31, a reflection of the company’s continued focus on safe, reliable operations, president and CEO Eira Thomas said in a statement. She indicated that the company’s strategy had yielded increased productivity at lower costs and provided a solid foundation to support Lucara’s next stage of growth – an underground expansion at the Karowe mine, in Botswana, which has the potential to extend its mine life to 2040.
