Vancouver, British Columbia–(Newsfile Corp. – March 26, 2026) – NexMetals Mining Corp. (TSXV: NEXM) (NASDAQ: NEXM) (“NEXM” or the “Company“) is pleased to report visual results from drill hole SMD-26-209, part of its ongoing surface drilling program targeting the emerging Flexure Zone (“Flexure Zone“) at the Selebi Main deposit in Botswana (see Figure 1). Drill core photos from hole SMD-26-209 are presented in Figure 2. Drilling continues to intersect strong zones of sulphide mineralization outside of the 2024 Mineral Resource Estimate (“2024 MRE“), reinforcing the scale and continuity of the Selebi system.
Highlights:
What You Need to Know: Strong Visual Intercept from SMD-26-209
- Drill hole SMD-26-209 intersected a 10.50 metre interval of blebby, stringer and massive sulphides, including:
- 3.05 metres of massive sulphides; and
- 5.95 metres of massive sulphides
- Assays are pending and will be reported once received and validated.
What Does This Mean?
- Visual results from SMD-26-209 are consistent with SMD-25-205 (11.05 metres of 7.31% CuEq, see news release dated February 26, 2026), located 350 meters to the northeast, demonstrating expansion potential within the Flexure Zone, extending down-dip and down-plunge from Selebi Main.
- The presence of thick, continuous massive sulphide intervals in holes spaced more than 300 meters apart supports the Company’s interpretation of a robust and laterally extensive mineralized system at Selebi Main.
- The combination of massive, blebby and stringer sulphides indicate a strong sulphide system with potential for scale, particularly when integrated with ongoing borehole electromagnetic (“BHEM“) targeting.
Sean Whiteford, CEO and Director of the Company, commented: “Hole SMD-26-209 continues to demonstrate thick intervals of massive sulphide mineralization beyond the current mineral resource footprint. Step-out drilling within the emerging Flexure Zone is not only highlighting expansion potential, but also validating our BHEM targeting, with mineralization consistently intersected where modeled. These results point to potential for increased thickness at depth, which could have positive implications for project economics. With several additional holes in progress targeting this zone, we look forward to further defining the extent and characteristics of the Flexure Zone. The visual results alone highlight the strength of the system, and we look forward to validating these observations with assays.”

Detailed Drilling and BHEM Information
SMD-26-209 was completed to 1,861.9 metres and intersected a 10.5 metre interval of mineralization from 1,768.65 metres to 1,779.15 metres. The mineralized zone is comprised of blebby, stringer and massive sulphides and includes two intervals of massive sulphides with thicknesses of 3.05 metres and 5.95 metres. The mineralized interval is characterized by pyrrhotite-rich massive sulphides with visible chalcopyrite, along with magnetite and minor amphibolite inclusions.
SMD-26-209 is the most recent Selebi Main Expansion drillhole that defines the newly emerging “Flexure Zone”. SMD-26-209 is located 350 metres UTM southwest of SMD-25-205 (11.05 metres of 7.31% CuEq, 3.00% Cu and 2.09% Ni) and 345 metres UTM northwest of SMD-26-208 that intersected three zones of sulphide mineralization (see news release dated February 26, 2026).
This Flexure Zone is located down-dip and down plunge of the 2024 MRE and was discovered by the follow-up of drilling and BHEM results in SMD-25-201 and subsequent drill holes. SMD-25-201 was the first hole that targeted large BHEM plates at the southernmost extent of the gap between the Selebi Main and Selebi North deposits (see news release dated February 26, 2026).
To date, a total of 19,130 metres in 8 completed holes, 1 hole extension, 3 abandoned holes and 3 in-progress holes have been completed as part of the surface drilling program. Drill hole collar details are provided in Table 1 below.

| HOLE ID | UTM East | UTM North | Elevation | Dip | True North Azimuth | Hole Length |
| SMD-26-209 | 582465.3 | 7563469.4 | 908.0 | -74.5 | 100.2 | 1861.9 |
Qualified Person
All scientific and technical information in this news release has been reviewed and approved by Sharon Taylor, V.P. Exploration of the Company, MSc, P.Geo, and a “qualified person” for the purposes of National Instrument 43-101 and Subpart 1300 of Regulation S-K.
Quality Control
The program is being executed using three company-owned underground Zinex U5 drills which were converted into surface A5 drills, and a Marcotte HTM2500 drill purchased by the Company capable of drilling to depths of 2,550 metres (NQ core).
Drill core samples are either NQ (47.75 mm diameter) or BQ (36.40 mm diameter). All samples are ½ core samples cut by a diamond saw on site and the remaining half of the core is retained for reference purposes. Samples are generally 1.0 to 1.5 metre intervals or less at the discretion of the site geologists. Sample preparation and lab analysis was completed at ALS Geochemistry in Johannesburg, South Africa. Commercially prepared Blank samples and certified Cu/Ni sulphide analytical control standards with a range of grades are inserted in every batch of 20 samples or a minimum of one set per sample batch. Analyses for Ni, Cu and Co are completed using a peroxide fusion preparation and ICP-AES finish (ME-ICP81). Analyses for Pt, Pd, and Au are by fire assay (30 grams nominal sample weight) with an ICP-AES finish (PGM-ICP23).
Holes are numbered as follows: SMD (Selebi Main Deposit) + year + hole number starting at 201.
BHEM Surveys
The BHEM surveys at Selebi utilize the Crone PEM system operated by local Botswana staff. Survey data is collected using a 3-component fluxgate probe collecting full waveform data. Surveys have been collected using timebases between 50 and 1000ms (0.25 Hz to 5 Hz). The data has been processed to a calculated residual step response to better quantify the conductive sources. This added processing has proven to be highly valuable because of the size of the highly conductive mineralized system.
