Lucara Diamond Corp. has unearthed a white diamond weighing 378 carats at its Karowe mine in Botswana, the second over 300 carats the deposit has produced since the start of the year.
The miner recovered the “magnificent,” gem-quality, unbroken, type IIa stone from the site’s south lobe M/PK(S) area, known for its large, high-quality rough, it said on Tuesday.
Earlier this month, Lucara retrieved a 341-carat, high-quality diamond at the site. Including this newest find, the company has unearthed 55 diamonds over 200 carats since 2015.
“The 378-carat [stone] joins a rare and special lineage of exceptional, high-value diamonds recovered at Karowe, and continues to highlight the wonderful diamond potential of Botswana,” said Lucara CEO Eira Thomas. “Continued and consistent recovery of [these] large diamonds…comes at a critical time and provides continued strength and additional foundation to the opportunity to finance and build the underground expansion at Karowe.”
