Lucara Diamond Corp announces the draw down of $10.0 million of the $63.0 million limited shareholder standby undertaking (the Standby Undertaking) provided by the Company's largest shareholder, Nemesia, to address a funding shortfall of the Karowe underground project (the UGP). Nemesia provided the Standby Undertaking in connection with the Company's amended senior secured project financing debt package (the Rebase Amendments). The Standby Undertaking consists of two components; (i) $28.0 million to support liquidity shortfalls until completion of the UGP; and (ii) $35.0 million as a funding shortfall guarantee in support for the UGP completion. Lucara announces recent notable diamond recoveries from the Company's 100% owned Karowe Mine in Botswana. In August 2025, the Company recovered a 1,019.85 carat non-gem diamond through its Mega Diamond Recovery unit.
