Q1 2026 HIGHLIGHTS

Q1 2026 marked a transformational quarter for Lucara, with the successful completion of its equity and bond financings for the Karowe Underground Project (the "UGP"), strengthening the Company's balance sheet and positioning it for long-term value creation.

Strengthened capital structure and liquidity

• Closed a C$165.0 million equity financing on January 29, 2026, reflecting strong investor support.
• Successfully issued $350.0 million of senior secured bonds on March 27, 2026, with a tap option which allows for an additional $50.0 million of issuance and an option to establish a revolving credit facility of up to $50.0 million.
• Fully repaid $220.0 million of project debt.
• Ended the quarter with a strong cash position of $244.3 million (December 31, 2025: $31.9 million).

UGP advancement

• Updated feasibility study confirms total capital cost of $779.2 million, with $472.4 million already invested, demonstrating significant project advancement.

Operational resilience and high-value recoveries

• Recovered 100 Specials¹, including five diamonds greater than 100 carats and one exceeding 300 carats.
• Notable recovery of a 36.92 carat blue Type IIB diamond recovered from the run-of-mine stockpile, comprised of ore previously mined but not yet processed, reinforcing Karowe's reputation for rare, high-value stones.
• Continued strong processing performance, with throughput aligned with operational expectations.

Continued strong safety record

• The Karowe Diamond Mine ("Karowe") registered no lost time injuries during Q1 2026. The rolling twelve-month Total Recordable Injury Frequency Rate (TRIFR) for the Karowe Mine was 0.32 (Q1 2025: 0.36).

Financial performance

• Q1 2026 revenue was $21.8 million (Q1 2025: $30.3 million), reflecting a higher proportion of stockpile processing during the period due to unseasonal weather impacting open pit mining. Stockpile material is inherently variable in grade and quality, which affected realized recoveries in the quarter. Open pit mining resumed on March 26, 2026 and is expected to conclude later in the year.
• Operating cost per tonne processed of $24.74, reflecting disciplined cost management despite inflationary pressures and transitional mining activities.
• Despite lower revenue and higher costs in Q1 2026, the Company is maintaining its full year outlook. Revenue guidance remains unchanged at $100.0 million to $130.0 million, supported by the planned return to open pit mining, with all other guidance parameters also reaffirmed. 

William Lamb, President & CEO commented: "Q1 2026 represents a pivotal milestone for Lucara. The successful execution of our financing strategy for the Karowe Underground Project has strengthened our balance sheet, providing the financial flexibility to advance one of the world's most exceptional diamond assets.

Operationally, Karowe continues to demonstrate its resilience and unique value proposition. The recovery of a 36.92 carat blue diamond, alongside multiple large stones recovered from run-of-mine stockpile material, underscores the consistent delivery of high-quality, premium diamonds that differentiate Lucara globally.

While broader diamond market conditions remain mixed, our focus on large, high-value stones positions us well to benefit from improving fundamentals in this segment.

With steady progress on the underground project and continued operational execution, we are well positioned to unlock long-term value for our shareholders."

KAROWE UNDERGROUND PROJECT UPDATE

The UGP is designed to access the highest value portion of the Karowe orebody, with initial underground production predominantly from the EM/PK(S)² unit. The UGP is expected to extend the mine life to 2038.

The updated feasibility study announced on January 30, 2026 (link to news release) confirmed a total cost at completion of $779.2 million, including contingency. As at March 31, 2026, $472.4 million had been incurred, with a further $117.7 million committed but not yet incurred. The study incorporates construction progress, updated exchange rates, inclusion of Legacy³ stone values, and revisions to hydrogeological and geomechanical models, mine design, mining method, and scheduling. From H1 2026 to H1 2028, processing will continue using a combination of open pit ore and run-of-mine stockpiled materials, comprising ore previously mined but not yet processed.

The project has been materially de-risked following completion of shaft sinking activities in 2025, including the 776 metre production shaft and 729 metre ventilation shaft. The UGP has achieved 2,249 lost-time injury free days, with a project-to-date TRIFR of 0.54, below the target of 0.90, and a 12-month rolling TRIFR of 0.34.

Total UGP capital expenditures for Q1 2026 were $19.0 million⁴, primarily related to shaft equipping, lateral development, and surface infrastructure.

During Q1 2026, the ventilation shaft advanced approximately 491 metres of lateral development across the 310-level⁵ and 285-level, bringing total lateral development to 1,245 metres, ahead of the planned handover stage to the lateral development contractor. Water intersections encountered were effectively managed through targeted grouting. At the production shaft, shaft equipping was completed to surface, including installation of guides and buntons, followed by decommissioning of sinking infrastructure and commencement of headgear internal steel changeover works.

The lateral development contract awarded in Q4 2025, covers all development from the production shaft to the orebody, including extraction, undercut and long-hole drilling level infrastructure, underground crushing facilities, and associated services. During Q1 2026, the contractor completed its site visit and kickoff meeting, with onboarding of key personnel and mobilization activities underway as at March 31, 2026.

Surface infrastructure works continued during the quarter, including civil construction and procurement of long-lead ventilation fan components.

Activities planned for the UGP in Q2 2026 include the following:

• Continue with production shaft headgear changeover, including stripping and installation of permanent steel at remaining headgear levels, and advancing bin and chute installation works.
• Advance lateral development at the 310-level, including side-loading conveyor installation and sump completion at the 285-level, and initiation of 470-level development works for ore pass raiseboring.
• Complete civil works and commence installation of main surface ventilation fans.
• Continue with operational readiness including advancing staffing plans, finalizing operating procedures, and preparing for operation and maintenance of permanent infrastructure.

OPERATIONS UPDATE

Open pit mining activities at Karowe were temporarily suspended during the first quarter due to unseasonal and excessive rainfall, resulting in elevated water levels within the pit. Operations resumed in the open pit on March 26, 2026. During this period, the Company maintained uninterrupted processing operations by utilizing run-of-mine stockpiled material. While this approach ensures continued throughput, the increased reliance on stockpiles, which are generally lower in grade and diamond quality, contributed to a softer revenue performance in Q1 2026.

DIAMOND MARKET

The diamond market remains characterized by near-term pricing pressure in mid-range and lower-quality stones due to elevated inventory levels and cautious consumer demand, alongside continued competition from lab-grown diamonds. However, prices for larger, high-quality natural diamonds have shown signs of stability, supported by constrained global supply and recent price increases for stones above five carats, as announced by De Beers. Longer-term supply fundamentals remain supportive, with declining production from major producers.

FINANCIAL HIGHLIGHTS – Q1 2026

QUARTERLY SALES RESULTS

Diamond Sales

Diamonds from Karowe are sold through three sales channels: through a diamond sales agreement with HB Trading BV ("HB"), through quarterly tenders, and on the Clara Diamond Solutions ("Clara") sales platform. 

For the three months ended March 31, 2026, the Company reported revenue of $13.6 million from HB, compared to $19.3 million for the same period in 2025. Revenue from HB accounted for 62% of total revenue recognized in Q1 2026, compared to 64% in Q1 2025. The decline in HB revenue was driven by both a lower volume of carats sold and a lower average price per carat. Revenue from HB includes "top-up" and "top-down" payments, which are made to or from the Company when the final polished diamond sales price differs from the estimated initial polished value. Given the time required to fully monetize a stone through this process, top-up and top-down payments can introduce variability into HB revenue on a quarter-to-quarter basis.

For the three months ended March 31, 2026, tender sales totaled $7.2 million compared to $9.3 million in Q1 2025, while Clara sales totaled $1.0 million compared to $1.7 million in Q1 2025. Compared to Q1 2025, a higher volume of carats were sold through tender while fewer were sold through Clara. Average prices per carat declined across both channels, with tender prices falling 30% and Clara prices falling 24%, reflecting continued pricing pressure on mid-range and lower-grade stones amid high industry inventory levels, and cautious consumer sentiment.

QUARTERLY RESULTS FROM OPERATIONS – KAROWE MINE

2026 OUTLOOK

This section of the news release provides management's production and cost estimates for 2026. These are forward-looking statements and subject to the cautionary note regarding the risks associated with such statements.

The table above reflects the natural variability in the resource, including both recovered grade and diamond quality, which may influence the revenue guidance for 2026. In 2026, the Company expects to process 2.6 to 2.9 million tonnes of ore primarily from run-of-mine stockpiled materials. The assumptions for carats recovered and sold as well as tonnes of ore processed are consistent with achieved plant performance in recent years. Run-of-mine stockpiled material (North, Centre, South Lobe) and life-of-mine stockpiles will provide mill feed until H2 2027 when UGP development ore is scheduled to start replacing stockpiles with high-grade ore from the UGP. Full scale underground production is planned for H1 2028.

In 2026, capital costs for the UGP are expected to be up to $110 million. Expenditures in 2026 will focus predominantly on shaft equipping and advancing lateral development. Surface works will focus on the removal of stage and ropes, headgear change over, and main ventilation fan installation.

Sustaining capital is expected to be up to $11.5 million with a focus on the replacement and refurbishment of key asset components and tailings advancement.
