Mr. Sean Whiteford reports

NEXMETALS OUTLINES 2026 TECHNICAL WORK PROGRAMS TO ADVANCE SELEBI AND SELKIRK DEPOSITS IN BOTSWANA AND ACCELERATES CEO TRANSITION

Nexmetals Mining Corp. has outlined the strategy and work programs for 2026 across the copper-nickel-cobalt-platinum-group-element sulphide Selebi and Selkirk mines in Botswana. Building on the company's success made in 2025 that expanded mineralization and advanced technical studies, the company believes it is well positioned in 2026 to accelerate resource growth and advance both projects toward future economic assessments. The company is also pleased to report that the previously announced leadership transition has been completed ahead of schedule, and Sean Whiteford has assumed the role of chief executive officer. The board of directors would like to formally welcome Mr. Whiteford to his new role and thank Morgan Lekstrom for his contribution to the successful succession.

Achievements in 2025 -- setting the foundation for growth:

• Secured unencumbered title to the Selebi and Selkirk assets in Botswana following completion of the asset purchase agreement milestone payment;
• Strengthened balance sheet through strategic financings to support exploration, underground development and technical programs across Selebi and Selkirk;
• Advanced the drill program targeting the two-kilometre gap between the Selebi Main and Selebi North deposits;
• Advanced surface and underground exploration drilling at the Selebi Main and Selebi North deposits, expanding the mineralized footprint and improving geological understanding, and progressed underground development at Selebi North;
• Advanced metallurgical flow sheet development, including successful bench-scale testing of blended Selebi Main and Selebi North material, with results demonstrating that a clean, high-grade, saleable separate copper and nickel cobalt concentrates could be produced;
• Completed the metallurgical drill program at Selkirk and advanced metallurgical flow sheet development work;
• Drill core resampling program at Selkirk was completed, supporting resource modelling and future economic studies.

2026 strategy highlights -- moving toward economic studies

Selebi mine:

• Selebi Main surface drilling program -- borehole electromagnetic surveying and drilling approximately 30,000 metres at Selebi Main targeting resource expansion;
• Selebi North underground development -- additional development to establish better drilling access for future infill drilling required for economic studies;
• Metallurgy -- continue to refine and optimize the metallurgical flow sheet for Selebi mine material;
• Mineral resource estimate update -- planned completion in second half 2026;
• Preliminary economic assesment -- planned completion in second half 2026.

Selkirk mine:

• Metallurgy -- continue to progress the metallurgical testing and provide technical basis to support resource update and future economic studies;
• MRE update -- planned completion in first half 2026;
• Preliminary economic assessment -- timing contingent on continuing technical results.

What to expect in first half 2026:

• Initial assay and BHEM results from the surface drilling program targeting the two-kilometre gap potentially linking the Selebi deposits, also known as the Hinge program;
• Remaining assay and BHEM results from the Selebi North underground drilling program;
• Metallurgical results from continuing Selkirk flow sheet and locked cycle test work;
• Assay results from the Selkirk resampling program;
• Assay results from exploration drilling on airborne electromagnetic targets and soil sampling programs.

Sean Whiteford, chief executive officer of the company, commented: "This year represents an important step forward for the company as we move from foundational work into focused, data-driven resource growth and technical derisking across Selebi and Selkirk. The success delivered throughout 2025 has positioned us well for this next phase. I want to sincerely thank Morgan for his contributions to Nexmetals.

"With additional drills mobilized and the operational control that comes from owning our rigs, we are advancing our program efficiently and responsibly. Our 2026 work plan is structured to deliver drilling results and metallurgical data required to support updated resource estimates and future economic studies. We expect a steady flow of technical results throughout the year, and believe the work completed in 2026 will significantly advance the projects and fully establish the scale and opportunity of the Selebi and Selkirk deposits. We look forward to sharing additional detail on our 2026 programs in due course."

Selebi Main surface drilling and BHEM program

The company has initiated a resource expansion drilling program supported by BHEM, building on targets identified from the Hinge drilling program. The program will test both the Main zone and the Lower zone, where historical drilling and BHEM modelling suggest increasing thickness and continuity downdip and down plunge toward the north. Drill hole sequencing will be informed by continuing geophysical interpretation, allowing the company to position toward conductive plates as results are received. The objective is to meaningfully expand the inferred resource base and provide the geological data necessary to support an updated MRE planned later in 2026. As drilling progresses, Nexmetals expects results to be released on a steady basis throughout the year.
