LUCARA ANNOUNCES Q1 2026 RESULTSMay 7, 2026 5:37 PM
PR Newswire (US) VANCOUVER, BC, May 7, 2026 /PRNewswire/ -- (TSX: LUC) (BSE: LUC) (Nasdaq FNGM: LUC) PDF VersionLucara Diamond Corp. ("Lucara" or the "Company") today reports its results for the quarter ended March 31, 2026. All amounts are in U.S. dollars unless otherwise noted. References to "C$" are to Canadian dollars.Q1 2026 HIGHLIGHTSQ1 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 liquidityClosed 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 advancementUpdated 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 recoveriesRecovered 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 recordThe 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 performanceQ1 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. _______________1 Specials are defined as stones above 10.8 carats.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 UPDATEThe 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.______________________2 EM/PK(S): Eastern magmatic/pyroclastic kimberlite (south).3 Legacy stone refers to rough stones sold for a value greater than $5.0 million.4 Excludes qualifying borrowing cost capitalized.5 Each level is equivalent to a metre above sea level.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 UPDATEOpen 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 MARKETThe 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

$    21.8$    30.3Diamond SalesDiamonds 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.____________________6 Cost Overrun Reserve Account.QUARTERLY RESULTS FROM OPERATIONS – KAROWE MINE

(1)Operating cash costs are a non-IFRS measure. See "Non-IFRS Measures" in the Company's MD&A.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.

PR Newswire (US)

VANCOUVER, BC, March 4, 2026 /PRNewswire/ -- (TSX: LUC) (BSE: LUC) (Nasdaq FNGM: LUC) PDF VersionLucara Diamond Corp. ("Lucara" or the "Company") today reports its results for the quarter ended December 31, 2025. All amounts are in U.S. dollars unless otherwise noted. References to "C$" are to Canadian dollars. FISCAL 2025 HIGHLIGHTSA total of 353,302 carats were sold (2024: 399,215 carats), generating $159.7 million in revenue (2024: $203.9 million). Revenue for the year includes the sale of the Seriti, a 1,094 carat diamond sold to HB Trading BV ("HB") for an initial polished value of $12.0 million. A further $7.9 million in top-up revenue was earned during 2025 following the sale of polished outcomes from the Seriti. Revenue for the comparative year includes the sale of the Sethunya, a 549 carat Type IIA white gem quality diamond and the Eva Star, a 1,080 carat Type IIA diamond. The Company sold the Sethunya and Eva Star for a combined sum of $54.0 million and in Q4 2024 recognized $44.0 million in revenue net of fees, excluding royalties.The production and ventilation shafts both reached final depth in 2025 marking a key milestone toward completion of the Karowe Underground Project ("UGP"). Significant process was made in lateral development connecting the two shafts across multiple levels. The UGP achieved over 2,000 days without a lost-time injury.On December 1, 2025, the Company awarded a lateral development contract to Group R Mining and Exploration Botswana (Pty) Ltd. for the execution of all underground lateral development from the production and ventilation shafts to the ore body, including construction of the extraction level, underground crushing chamber, fine ore bins, and pump stations with associated infrastructures required to advance to the kimberlite.The recovery of 772 Specials1 (2024: 807 Specials) equated to 7.1% (2024: 7.6%) by weight of the total carats recovered from direct ore feed in 2025. During 2025, the Company recovered 31 stones over 100 carats, including three stones that exceeded 1,000 carats. Significant recoveries in 2025 included a 1,476 carat non-gem diamond, a 2,036 carat near-gem diamond, a 1,0152 carat non-gem diamond and a 37.42 carat pink Type IIa diamond.A total of 89,596 carats were recovered in Q4 2025; 86,110 carats were from direct open pit ore feed and stockpiles, at a recovered grade of 12.2 carats per hundred tonnes ("cpht"), and an additional 3,486 carats were recovered from processing historical recovery tailings.All key operational and financial metrics set out in the Company's 2025 Revised Guidance were achieved.A total of 1.9 million tonnes ("Mt") (2024: 3.0 Mt) of ore was mined with 2.8 Mt of ore processed (2024: 2.9 Mt).Financial highlights for 2025 included:Operating margins of 52% were achieved compared to 61% in 2024. The 9% decrease reflects a 22% decrease in revenue partially offset by a 3% decrease in operating expenses.Operating cost per tonne processed was $27.15 per tonne, a decrease of 3% compared to the 2024 operating cost of $27.89 per tonne. The continued impact of inflationary pressures, particularly labour, has been well managed by the operation. Operating cost per tonne processed is a non-IFRS measure.Cash position and liquidity as at December 31, 2025:Cash balance of $31.9 million.$190.0 million has been fully drawn from the project finance facility ("Project Facility") for the UGP, along with $30.0 million fully drawn from the working capital facility ("WCF" and together with the Project Facility, the "Facilities").Working capital (current assets less current liabilities) of $33.6 million.The Company drew $28.0 million from the Cost Overrun Reserve Account ("CORA") in exchange for its largest shareholder, Nemesia S.à.r.l. ("Nemesia"), agreeing to amend the terms of its limited shareholder standby undertaking through to UGP completion.The Company drew $28.0 million from the $63.0 million funding support provided by Nemesia and issued an unsecured debenture (the "Debenture") in connection with the drawdown. The Debenture matures on June 30, 2031.____________________________________1Specials are defined as stones above 10.8 carats.2The carats reflect the final cleaned weight of the rough stone. The stone was previously reported at 1,019.85 carats.SUBSEQUENT TO FISCAL 2025 HIGHLIGHTSOn January 29, 2026, the Company closed a non-brokered private placement for total gross proceeds of C$165.0 million (the "January 2026 equity financing"). The Company issued an aggregate of 1,031,250,000 common shares at a price of C$0.16 per common share.On January 30, 2026, the Company filed an updated Feasibility Study (the "Updated Feasibility Study") prepared in accordance with National Instrument 43-101 – Standards of disclosure for Mineral Properties which provided an update on the progress and estimate for the total costs of the UGP. The revised forecasted costs at completion are $779.2 million, an increase of 14% from the prior estimate in July 2023, of which $469.4 million has been incurred as at December 31, 2025.On March 3, 2026, the Company and the Lenders (as defined below) entered into a waiver agreement (the "Subsequent Waiver Agreement"). The Subsequent Waiver Agreement approved a reduction of the required CORA balance from $33.7 million to $21.2 million.William Lamb, President & CEO commented: "Our 2025 performance reflects both the resilience of our operations and the unique value proposition of Karowe. We continued to achieve strong operating margins of 52% and met all key metrics set out in our 2025 Revised Guidance.Operationally, 2025 was a milestone year for the Karowe Underground Project. Both the production and ventilation shafts reached final depth, lateral development advanced across multiple levels, and the project surpassed 2,000 days without a lost-time injury, an achievement that speaks to the strength of our safety culture. The award of the lateral development contract to Group R Mining and Exploration Botswana marks the transition to the next critical phase, advancing infrastructure toward the ore body and positioning us for long-term underground production.Karowe's ability to consistently recover large, high-value diamonds remains unmatched. In 2025, Specials accounted for 7.1% by weight of total recovered carats from direct ore feed, with 31 stones over 100 carats recovered, including three exceeding 1,000 carats and a rare 37.42 carat pink Type IIa diamond. These recoveries underscore the exceptional quality of the resource as we transition from open pit to underground mining.We strengthened our capital structure with the successful C$165 million equity financing completed in January 2026 The filing of our Updated Feasibility Study confirms a clear path to completion of the UGP, with $469.4 million already invested and a disciplined plan to deliver the project. Together, these achievements reinforce our confidence in Karowe's long-term potential and our commitment to creating sustainable value for our shareholders and stakeholders alike."GOING CONCERNAs of the date of this news release, the Company's Facilities to fund the UGP are fully drawn. The Company did not comply with the covenants under the Facilities requiring a technically signed off financial model by June 30, 2025 ("Financial Model Covenant"), the execution of a lateral development contract by July 31, 2025 ("Lateral Development Contract Covenant"), the requirement to provide a cost to complete certificate by August 31, 2025 ("Cost to Complete Covenant"), and the requirement to fully pay down the WCF for five successive business days at least once every 12 months (the "Clean Down" and collectively, the "Covenants"). On December 30, 2025, the Company and the lenders, a syndicate of six mandated lead arrangers (the "Lenders") entered into an agreement to waive all Covenant breaches and events of default (the "Waiver Agreement"). The Waiver Agreement provided extensions to the following covenants: the Financial Model Covenant and the Lateral Development Contract Covenant to February 28, 2026, the Cost to Complete Covenant to March 31, 2026, and the Clean Down to June 30, 2026. As of the date of this news release, the Company is in full compliance with its Facilities, including the Financial Model Covenant and the Lateral Development Contract Covenant, with no outstanding Covenant breaches.On March 3, 2026, the Company and the Lenders entered into a waiver agreement (the "Subsequent Wavier Agreement"). The Subsequent Waiver Agreement extends the Financial Model Covenant and Cost to Complete Covenant to July 15, 2026.Management has assessed the Company's ability to continue as a going concern for at least twelve months from December 31, 2025. Based on this assessment, the Company estimates that its working capital as at December 31, 2025, cash flow from operations, the January 2026 equity financing, and other committed sources of liquidity will not be sufficient to meet the revised forecasted costs at completion for the UGP of $779.2 million of which $469.4 million of costs have been incurred. Given that committed sources of liquidity are not sufficient to meet the revised forecast and remaining cost to complete, the Company is not expected to comply with the Cost to Complete Covenant by July 15, 2026, unless additional financing is obtained or the Lenders grant a waiver or extension for the Cost to Complete Covenant. The Company is continuing to evaluate additional financing options to support completion of the UGP. While the Company has previously been successful in raising financing, future fundraising efforts may not succeed or may fall short of the required amounts. These conditions cast significant doubt on the Company's ability to continue as a going concern.The Annual Financial Statements have been prepared on a going concern basis which assumes the Company will continue operations, realize assets, and settle its liabilities as they become due. The Company's Annual Financial Statements do not include adjustments that may be necessary if the Company is unable to continue normal operations; such adjustments could be material and affect asset recoverability, liability classification, expenses, and comprehensive income.DIAMOND MARKETThe long-term outlook for natural diamond prices remains cautious amid ongoing structural changes in the market. Lab-grown diamond prices have continued to decline through 2025 with production outweighing demand. Global natural diamond production is forecasted to decrease, following significant production guidance cuts by the major diamond producers.In the near term, premium-grade large natural diamonds are showing signs of potential price stability with De Beers recently announcing a positive price increase in rough diamonds above 5 carats in size, supported by limited global supply growth and a paucity of rough diamonds in these and larger sizes. However, mid-range and lower-grade stones remain under pricing pressure due to high inventories, cautious consumer sentiment, and the rise in the purchasing of lab-grown diamonds.KAROWE UNDERGROUND PROJECT UPDATEThe UGP is designed to access the highest value portion of the Karowe orebody, with initial underground carat production predominantly from the EM/PK(S)3 unit. The UGP is expected to extend the mine life to 2038.On January 30, 2026, the Company announced an update to the UGP schedule and budget (link to news release). Production from the UGP is anticipated in H1 2028 with a revised total cost at completion of $779.2 million (including contingency). As at December 31, 2025, capital expenditures of $469.4 million had been incurred. Committed, not yet incurred, UGP costs are $82.3 million as at December 31, 2025. The Updated Feasibility Study incorporates construction progress, revisions to exchange rates, inclusion of Legacy stone4 values, and costs incurred to date, and updates to hydrogeological and geomechanical models, mine design, method and scheduling. From H1 2026 to H1 2028, the Company will process a combination of ore from open pit operations and stockpiled materials.The UGP has progressed well, highlighted by reaching the bottom of the 776 metres ("m") production shaft and the 729 m ventilation shaft in 2025. The UGP has achieved 2,159 lost-time injury free days. During Q4 2025, the UGP achieved a twelve-month rolling Total Recordable Injury Frequency Rate ("TRIFR") of 0.67. The UGP to date TRIFR up to December 31, 2025 was 0.56.A total of $75.8 million5 was spent on the UGP in 2025 with $20.3 million5 in Q4 2025. Expenditures were primarily directed toward advancing shaft sinking, developing the 245-level6, 285-level, 310-level and 335-level to connect the shafts and initiating lateral development.In Q4 2025, the Company executed a lateral development contract covering all underground lateral development from the production and ventilation shafts to the ore body. The scope includes construction of the extraction level, underground crushing chamber, fine ore bins, pump stations with associated vertical dams, drilling horizons, workshop facilities, and all connecting infrastructure required to advance towards the kimberlite.___________________________________3EM/PK(S): Eastern Magmatic/Pyroclastic Kimberlite (South).4Legacy stone refers to rough stones sold for a value greater than $5.0 million.5Excludes qualifying borrowing cost capitalized.6Each level is equivalent to a metre above sea level.Ventilation shaft Q4 2025 developments:Continued with 285-level station works, cat-walk and installation of a 110kw ventilation fan.Commissioned the 285-level temporary pump station.Developed 59.95 m on the 310-level and 24.5 m top cut on the 582-level.Completed sinking to shaft bottom.Production shaft Q4 2025 developments:Continued with pre-assembly and modifications of shaft station steel for construction at the 285-level and 310-level.Installation of shaft bottom spillage and deflection wall.Continued with equipping the production shaft to the 310-level and 285-level loading pocket.Related infrastructure Q4 2025 developments:Completed the Banksman cabin and continued with procurement of main surface ventilation fans.Advanced mining engineering, focusing on underground infrastructure and finalizing drilling level plans.Activities planned for the UGP in Q1 2026 include the following:Finalize production shaft equipping and headframe modifications.Advance lateral development towards the ore extraction and undercut levels on the 285-level and 310-level.Equip shaft from 310-level station to surface, removal of stage and ropes and commence head frame change over.Continue with operational readiness including advancing staffing plans and efforts to prepare for operation and maintenance of permanent infrastructure and establish operating procedures.FINANCIAL HIGHLIGHTS – Q4 2025

Revenue from HB accounted for 58% of total revenue recognized in Q4 2025, down from 79% in Q4 2024. Excluding the Sethunya and Eva Star, revenue from HB for Q4 2024 would have totaled $18.1 million. On a comparable basis, excluding Legacy stone sales in Q4 2024, revenue increased by 10% driven by a higher volume of carats sold to HB.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. Revenue from HB fluctuates with the sale of Specials and Legacy Stones. As of December 31, 2025, the Company had $9.5 million in current trade receivables from HB (December 31, 2024: $18.4 million).For the three months ended December 31, 2025, tender sales totaled $11.1 million, compared to $13.2 million in Q4 2024, while Clara sales totaled $3.5 million consistent with Q4 2024. Compared to Q4 2024, a higher number of carats were sold through the Clara platform while fewer were sold via tender. Average prices per carat declined for both channels, falling 7% for tender and 11% for Clara.QUARTERLY RESULTS FROM OPERATIONS – KAROWE MINE

(1)Operating cash costs are a non-IFRS measure. See "Non-IFRS Measures".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 3.0 million tonnes of ore including waste, primarily from 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. Stockpiled material (North, Centre, South Lobe) from working stockpiles and life-of-mine stockpiles will provide mill feed until 2027 when UGP development ore is scheduled to start offsetting 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, and headgear change over.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. APPOINTMENT OF NEW AUDITORLucara also announces that it has changed its auditors from PricewaterhouseCoopers LLP ("Former Auditor") to Ernst & Young LLP ("Successor Auditor") effective March 3, 2026 and subsequent to the filing of the Annual Financial Statements and related disclosures ("Effective Date").The Former Auditor's Botswana member firm ("PwC Botswana") is subject to mandatory audit firm rotation requirements of the Botswana Accountancy Oversight Authority as it relates to the Company's Botswana subsidiary. PwC Botswana will be completing its maximum permitted tenure as the auditor of the Company's Botswana subsidiary following the completion of their audit for the year ended December 31, 2025, at which point a new auditor for the Botswana subsidiary will be appointed. To promote efficiency and consistency by aligning the auditors of the Company and its Botswana subsidiary, the Company requested that the Former Auditor resign as of the Effective Date. The Board of Directors of the Company appointed the Successor Auditor, as of the Effective Date, to fill the vacancy and to hold office until the Company's next annual general meeting.There were no reservations in the Former Auditor's audit reports for any financial period during which the Former Auditor was the Company's auditor. There are no "reportable events" (as the term is defined in National Instrument 51-102 – Continuous Disclosure Obligations) between the Company and the Former Auditor.In accordance with National Instrument 51-102, the Notice of Change of Auditor, together with the required letters from the Former Auditor and the Successor Auditor, have been reviewed by the Company's Audit Committee and Board and will be filed on SEDAR+ accordingly.On behalf of the Board,William Lamb
