/NOT FOR DISTRIBUTION TO U.S. NEWS WIRE SERVICES OR DISSEMINATION IN THE UNITED STATES./

VANCOUVER, BC, Jan. 29, 2026 /PRNewswire/ — (TSX: LUC) (BSE: LUC) (Nasdaq FNGM: LUC)

Lucara Diamond Corp. («Lucara» or the «Company») is pleased to announce that it has closed its previously announced non-brokered private placement, which was originally announced on January 9, 2026 (see January 9, 2026 News Release), and was subsequently upsized to total gross proceeds of $165.0 million on January 14, 2026 (see January 14, 2026 News Release) due to strong investor demand. All dollar amounts reflected in Canadian dollars unless otherwise stated. PDF Version

William Lamb, President and CEO of Lucara, commented, «We are very pleased with the outcome of the recent oversubscribed private placement, which included participation of a number of institutional investors from around the world as well as the Lundin Family Trusts. This financing will enhance our ability to accelerate key developments on the Karowe Underground Project planned for 2026.»

Equity Private Placement

The Company issued an aggregate of 1,031,250,000 common shares in the capital of the Company (the «Common Shares») at a price of $0.16 per Common Share for aggregate gross proceeds of $165.0 million (the «Private Placement»). In connection with the Private Placement, the Company paid a $2.5 million finder’s fee in connection with a portion of the Private Placement to select finders including BMO Nesbitt Burns Inc., Haywood Securities Inc., Leede Financial Inc., Canaccord Genuity Corp., and Pareto Securities AB, excluding the participation of the Lundin Family Trusts (see January 19, 2026 News Release). All Common Shares issued pursuant to the Private Placement are subject to a four-month statutory hold period under applicable Canadian securities laws.

The Company expects that the net proceeds of the Private Placement will be used to address the Company’s liquidity shortfall to enable it to continue advancing the Karowe Underground Project (the «UGP» or the «Project») while pursuing longer-term Project financing, including for shaft equipping, conveyance commissioning and lateral development, extraction and drill horizon development, as well as for general working capital and corporate purposes.

The Company expects that full financing for the UGP will be achieved through a combination of operating cash flows, the Private Placement, additional debt financing, and ongoing collaboration with the Company’s existing lenders to address any remaining funding requirements. The Company is considering different alternatives for such additional debt financing, including a potential bond issue whereby the Company has mandated Clarksons Securities AS and Pareto Securities AB as advisors.

TSX Exemption from Shareholder Approval Requirement

The Company relied on the financial hardship exemption under Section 604(e) of the Toronto Stock Exchange (the «TSX») Company Manual (the «Exemption») in connection with the Private Placement (see January 19, 2026 News Release), which has been accepted by the TSX.
