NEWS RELEASE

LUCARA ANNOUNCES STRATEGIC SHIFT IN UNDERGROUND PROJECT MANAGEMENT

Vancouver, BC – March 31, 2025 /CNW/ (LUC – TSX, LUC – BSE, LUC – Nasdaq FNGM)

Lucara Diamond Corp. ("Lucara" or the "Company") today announced a strategic change in the management of its

Karowe underground project ("UGP") in Botswana. The Company has terminated its Engineering, Procurement and

Construction Management (“EPCM”) contract with JDS Energy & Mining Inc. ("JDS") for the development of the UGP,

effective March 31, 2025. The Company has entered into a Master Service Agreement (“MSA”) with JDS to complete

specific engineering components of the project, while all site-based contracts and activities will transition to owner-

managed operations.

This decision aligns with Lucara's commitment to optimizing project execution and maximizing shareholder value.

The shift to owner-managed operations for site-based activities is expected to provide several benefits, including:

1. Enhanced cost control and operational efficiency

2. Improved flexibility in decision-making and resource allocation

3. Direct oversight of critical project milestones and timelines

4. Leveraging Lucara's extensive in-house expertise and knowledge of the Karowe mine

The UGP continues to make significant progress. The production shaft has now reached over 7 20 meters below

surface and the ventilation shaft has now reached over 680 meters below surface. Substantial advancements have

been made on the production man and material s winder building, with the majority of the required surface

infrastructure already in place. This includes the installation of permanent bulk air coolers and other critical

components, positioning the project for continued success as it moves forward under the new management

structure.

William Lamb, President and CEO of Lucara, commented on the transition: "We are confident that this strategic shift

in project management will allow us to better leverage our team's deep understanding of the Karowe mine and its

unique characteristics. By taking direct control of site-based activities, we are positioning ourselves to respond more

rapidly to project needs and challenges. This approach will enable us to drive the UGP forward with greater efficiency

and precision, ultimately delivering enhanced value to our shareholders and stakeholders."

The Company appreciates the contributions made by JDS to date and looks forward to their continued involvement

under the MSA in specific engineering aspects of the project. Lucara remains committed to the successful

development of the UGP, which will extend the life of mine at Karowe and secure its position as a leading producer

of large, high-quality diamonds.

On behalf of the Board,

William Lamb

President and Chief Executive Officer
