On July 22, 2026, NexMetals Mining Corp. (the “Company”) issued a news release reporting assay results from drill holes SMD-26-210, 212-W1, 213 and 214, part of its 30,000-metre surface drilling program targeting the emerging Flexure Zone within the Selebi Main deposit in Botswana. A copy of this press release is attached as Exhibit 99.1 hereto and is incorporated herein by reference. The Company undertakes no obligation to update, supplement or amend the materials attached hereto as Exhibit 99.1.
Cautionary Statements to Investors on Reserves and Resources
The news release furnished herewith uses the terms “mineral resources”, “indicated mineral resources” and “inferred mineral resources” as such terms are defined under Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”). NI 43-101 is a rule developed by the Canadian Securities Administrators, which establishes standards for all public disclosure a Canadian issuer makes of scientific and technical information concerning mineral projects.
On October 31, 2018, the SEC adopted new mining disclosure rules (“S-K 1300”) that are more closely aligned with current industry and global regulatory practices and standards, including NI 43-101, with which we comply because we are also a “reporting issuer” under Canadian securities laws. While S-K 1300 is more closely aligned with NI 43-101 than the prior mining disclosure rules of the Securities and Exchange Commission, there are some differences. Accordingly, there is no assurance any mineral resources that the Company may report as “indicated mineral resources” and “inferred mineral resources” under NI 43-101 will be the same as the reserve or resource estimates prepared under S-K 1300. Investors should not assume that any part or all of indicated mineral resources or inferred mineral resources will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to their existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any “indicated mineral resources”, or “inferred mineral resources” on the Company’s projects are or will be economically or legally mineable. Further, “inferred resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, investors are also cautioned not to assume that all or any part of the inferred resources exist. In accordance with Canadian rules, estimates of “inferred mineral resources” cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101.
The information in this Current Report on Form 8-K (including Exhibit 99.1 attached hereto) is being furnished and shall not be deemed to be filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise be subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and regardless of any general incorporation language in such filing.

NexMetals Reports 11.15 Metres of 7.65% CuEq (3.10% Cu, 2.21% Ni) at Selebi Main, Highlighting a Kilometre-Scale Trend of Thick, High-Grade Massive Sulphides
Vancouver, British Columbia, July 22, 2026 – NexMetals Mining Corp. (TSXV: NEXM) (Nasdaq: NEXM) (“NEXM” or the “Company”) is pleased to report assay results from drill holes SMD-26-210, 212-W1, 213 and 214, part of its 30,000-metre surface drilling program targeting the emerging Flexure Zone (“Flexure Zone”) within the Selebi Main deposit in Botswana (see Figure 1). The latest results continue to validate the Company’s data-driven exploration model, with drilling continuing to intersect thick, high-grade massive sulphides beyond the limits of the 2024 Mineral Resource Estimate (“2024 MRE”). Together with borehole electromagnetic (“BHEM”) targeting, these results define a growing kilometre-scale trend that remains open and supports the expansion potential of the Selebi system.
Highlights:
What You Need to Know: Four New Intersections and Strong Intercept from SMD-26-212-W1
| ● | Drill hole SMD-26-212-W1 intersected a 11.15 metre interval of massive sulphides grading 7.65% CuEq (3.10% Cu, 2.21% Ni), one of the most significant massive sulphide intercepts drilled at Selebi Main. |
| ● | The intercept confirms an emerging kilometre-scale trend of thick, high-grade massive sulphides, extending beyond the 2024 MRE. |
| ● | All four drill holes intersected sulphide mineralization, including multiple intervals of massive sulphides. |
| ● | The Flexure Zone is now defined by widely spaced drill holes approximately 200–300 metres apart, demonstrating significant lateral extent and continuity. |
| ● | Modeled BHEM anomalies show continuation north of drilling, indicating the system remains open for expansion. |
What Does This Mean?
| ● | Drilling at a nominal 200-metre spacing continues to intersect thick, high-grade massive sulphides demonstrating the growing scale of the Selebi Main deposit. |
| ● | SMD-26-212-W1 closely replicates SMD-25-205 (11.05 metres of 7.31% CuEq: see news release dated February 26, 2026) and correlates with historic hole sd119 (26.1m of 8.29% CuEq, 3.39%Cu, 2.38% Ni: see Selebi Technical Report), demonstrating that the Flexure Zone contains multiple thick, high-grade massive sulphide intersections. |
| ● | These results now outline a mineralized trend exceeding one kilometre in strike length, representing a compelling growth opportunity at Selebi Main. |
| ● | The close correlation between drill hole results and the strongest BHEM conductors validates the Company’s data-driven exploration approach and provides confidence in additional high-priority targets along strike. |
Next Steps
| ● | The 2026 Mineral Resource Estimate (“2026 MRE”) remains on track for completion in the third quarter of 2026. |
| ● | The Company has engaged TECT Geological Consulting to develop an integrated three-dimensional geological and structural model for Selebi North and Selebi Main. The model is expected to enhance the Company’s understanding of the geological controls of mineralization across the mining license, support future resource growth and improve drill targeting of thicker, higher-grade zones, and identify potential regional exploration targets. |
| 1 |
Sean Whiteford, CEO and Director of the Company, commented: “The Selebi Main deposit continues to exceed our expectations. Each phase of drilling has expanded our understanding of the system, while continuing to deliver exceptional grades and thicknesses. Historically, sd119 was viewed as a standalone thick, high-grade massive sulphide intersection. Today, results from SMD-25-205 and SMD-26-212-W1 demonstrate that even at a 200-metre drill spacing, we continue to intersect thick, high-grade massive sulphides. These results are defining an emerging trend extending for more than one kilometre beyond the 2024 MRE. Importantly, the trend remains open, and we are still refining our understanding of the geological and structural controls responsible for these thicker, higher-grade zones.
As we continue to define the scale and geometry of the system, understanding the geological and structural controls on mineralization
is becoming increasingly important, not only to enhance drill targeting, but also to support future resource modelling and potential
mine planning. We look forward to advancing our understanding through the development of an integrated geological and structural model
with TECT Geological Consulting.”

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 two Marcotte HTM2500 drills 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.
