VANCOUVER, BC , March 12, 2026 /CNW/ (TSX: LUC) (BSE: LUC) (Nasdaq FNGM: LUC)

Lucara Diamond Corp. ("Lucara" or the "Company") announces that it has successfully completed a private placement of US$350.0 million of senior secured bonds. The bonds will have a tenor of five years and will have a fixed coupon rate of 12.5 percent per annum, with interest payable in quarterly instalments. All amounts are in U.S. dollars unless otherwise noted. References to "C$" are to Canadian dollars. PDF Version

Settlement of the bonds is expected to occur on or around March 27, 2026, subject to the satisfaction of customary conditions precedent. Net proceeds from the bond issue will be used to repay Lucara's existing US$220.0 million senior secured project finance debt package, funding of two years of interest on the bonds on a dedicated debt service retention account, and the residual costs related to the underground project at the Karowe mine (the "UGP" or the "Underground Project"). The Company intends to make an application to list the bonds on the Oslo Alternative Bond Market.

Completing the US$350.0 million bond financing, along with the C$165.0 million raised in its equity offering in January 2026 (see January 29, 2026 news release), provides Lucara with sufficient access to capital to incur the US$779.2 million capital cost of the UGP, of which US$469.4 million has been incurred as at December 31, 2025 as contemplated in the Company's updated Feasibility Study prepared in accordance with National Instrument 43-101 and filed on January 30, 2026. Following closing of the bond financing, the Company expects to have sufficient funding to complete the UGP without further financing, provided the project moves forward on schedule and the Company is able to meet its production and revenue forecast.

William Lamb, President and CEO of Lucara comments: "Following our upsized and highly successful equity private placement in January, we are very pleased to announce the completion of this bond issuance marking the completion of the final step in securing the full financing package for the Karowe Underground Project. The bond issue attracted strong interest from a broad range of international investors reflecting continued confidence in the exceptional quality of the Karowe mine and its long-term value potential. With the project now fully financed, we can focus all our efforts on executing the remaining development work and advancing Karowe toward a new phase of sustainable, high-value diamond production."

Nemesia S.a.r.l., a private entity controlled by the trusts settled by the late Adolph Lundin (the Lundin Family Trust), was allocated US$30.0 million in the bond financing.

Clarksons Securities AS and Pareto Securities AS acted as Joint Bookrunners in connection with the bond placement.

On behalf of the Board,

William Lamb
President and Chief Executive Officer
