Strategic positioning and diamond market dynamics

• Karowe mine has yielded several of the world's largest diamonds, including the 2,488 carat Motswedi and the 1,109 carat Lesedi La Rona, with historic stones valued at over $250 million.

• High-value diamond recoveries continue, with 100 Specials recovered in Q1 2026, including five over 100 carats and one exceeding 300 carats.

• Downstream partnerships with luxury retailers provide stable demand and premium positioning.
