Winston Score History

The full picture

Lucara Diamond Corp. is a Canadian mining company that digs diamonds out of the ground and sells them. Its main asset is the Karowe mine in Botswana, Africa, which is known for producing very large, high-quality diamonds. Lucara is one of the few companies in the world that regularly recovers diamonds over 100 carats, including some of the largest gem-quality diamonds ever found.

The company makes money by selling rough diamonds, mostly to luxury jewelers and diamond traders. It also runs a sales platform called Clara, which uses data to match individual rough diamonds directly with manufacturers, cutting out traditional middlemen. Lucara operates almost entirely from the single Karowe mine, which keeps costs focused but also means the whole business depends on one location. The key near-term project is an underground expansion of Karowe, which is expected to extend the mine's life significantly but requires heavy capital spending that puts pressure on the company's finances.
