NexMetals (NEXM) logs thick massive sulphides at Selebi Main
Rhea-AI Filing Summary
NexMetals Mining Corp. reported new visual drilling results from hole SMD-26-219 at the Selebi Main deposit in Botswana, targeting the Flexure Zone. The hole intersected multiple thick intervals of semi-massive and massive sulphide mineralization and extends the emerging high-grade trend by approximately 450 metres, bringing the interpreted sulphide trend to about 1.45 kilometres in length outside the 2024 Mineral Resource Estimate.
Key visual intercepts include a 20.0 metre mineralized interval in the Main Zone and a 7.55 metre interval in the Lower Zone with 6.60 metres of massive sulphides; assays are pending for all intervals. Borehole electromagnetic survey results indicate conductors continuing down-dip and down-plunge toward Selebi North, supporting ongoing exploration potential. NexMetals also adopted an advance notice policy for director nominations, to be placed before shareholders for ratification at the next annual meeting, aiming to enhance governance and transparency around board elections.

Filing Explained
The drill result cannot enter the 2026 resource estimate, so its immediate effect is exploration evidence rather than a resource revision.
The company’s newly furnished 8-K leaves drill hole SMD-26-219 at a visual-results stage: assays are pending, and the hole was completed after the
Because of that cutoff, SMD-26-219 will not be included in the 2026 Mineral Resource Estimate; the filing therefore adds exploration evidence without revising that upcoming resource estimate with this hole.
Separately, the board-approved advance notice policy sets a deadline and required notice content for shareholders seeking to nominate directors, and will be submitted for ratification at the next annual meeting.

| Item 7.01 | Regulation FD Disclosure. |
On August 17, 2026, NexMetals Mining Corp. (the “Company”) issued a news release reporting visual results from drill hole SMD-26-219, part of its ongoing surface drilling program targeting the Flexure Zone at 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.

Exhibit 99.1
NexMetals Extends Trend of Thick Massive Sulphides to 1.45 Kilometres with Visual Intercept in Hole SMD-26-219 at Selebi Main
Vancouver, British Columbia, August 17, 2026 – NexMetals Mining Corp. (TSXV: NEXM) (Nasdaq: NEXM) (“NEXM” or the “Company”) is pleased to report visual results from drill hole SMD-26-219, part of its ongoing surface drilling program targeting the Flexure Zone (“Flexure Zone”) at the Selebi Main deposit in Botswana (see Figure 1). The hole intersected multiple thick intervals of semi-massive and massive sulphide mineralization, extending the emerging high-grade mineralized trend by approximately 450 metres beyond previously reported drilling. The trend, located within the Flexure Zone and outside the 2024 Mineral Resource Estimate (“2024 MRE”), continues to demonstrate significant expansion potential. Drill core photos from SMD-26-219 are shown in Figure 2.
What You Need to Know: Emerging Thick, High-Grade Trend Extended by a Further 450 metres to 1.45 kilometres
| ● | Emerging High-Grade Trend Extended: Drill hole SMD-26-219 is located approximately 450 metres down-plunge of SMD-25-205 (11.05 metres of 7.31% CuEq, see news release dated February 26, 2026) and 175 metres along strike of SMD-26-213 (22.90 metres of 3.02% CuEq). The new visual intercept provides further evidence that the emerging thick, high-grade mineralized trend continues at depth and extends well beyond the 2024 MRE. | |
| ● | Strong Visual Sulphide Mineralization in Two Zones: Hole SMD-26-219 intersected multiple intervals of sulphide mineralization, including a 20.0 metre mineralized zone that includes 1.6 meters of massive sulphides in the Main Zone and a 7.55 metre interval that includes 6.60 metres of massive sulphides in the Lower Zone. | |
| ● | Unlocking Footwall Potential: The 6.60 metre interval of massive sulphides, from 1,910.15 to 1,916.75 metres in the lower zone correlates with the lower zone interval in SMD-26-213 (7.45 m of 2.52% Cu and 1.54 % Ni) located 175 metres along strike, suggesting an extensive system. | |
| ● | Continued Evidence of Mineralized Continuity: Together with previously reported drill holes, SMD-26-219 provides further evidence that both the Main Zone and Lower Zone host thick, continuous sulphide mineralization over a significant distance within the Flexure Zone. | |
| ● | Assays Pending: Assays are pending for all intervals and will be reported once received and validated. | |
| ● | BHEM Highlights Continued Exploration Potential Toward Selebi North: Borehole electromagnetic survey (“BHEM”) results show that the conductor that correlates with the lower zone mineralization continues both down-dip and down-plunge toward Selebi North. |
Why This Matters
| ● | Previous drilling established an emerging trend of high-grade assay results within the Flexure Zone. | |
| ● | Hole SMD-26-219 extends that interpreted trend by approximately 450 metres and contains visual sulphide mineralization consistent with previously reported mineralized intervals. | |
| ● | While assays are pending, the continuity of thick sulphide mineralization over increasing distances, with holes spaced at nominal 200-to-300-metre intervals, continues to support the Company’s interpretation that the Flexure Zone at Selebi Main has significant potential for resource growth beyond the 2024 MRE. |
Next Steps
| ● | The 2026 Mineral Resource Estimate (“2026 MRE”) remains on track for completion in the third quarter of 2026. Drill holes completed subsequent to the resource cut-off date of July 31, including SMD-26-219, will not be included in the 2026 MRE but continue to support the Company’s strategy of expanding the Selebi resource base through ongoing exploration success. | |
| ● | 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. |

Sean Whiteford, CEO and Director of the Company, commented: “While assays are still pending, we’re extremely encouraged by the thickness and continuity of the sulphide mineralization we’re seeing in SMD-26-219. Together with our previously reported assay results, this hole continues to strengthen our confidence that we’re defining a significant mineralized trend well beyond the 2024 MRE. It’s particularly exciting because we have reached the cut-off date for the 2026 MRE, meaning this latest hole represents upside beyond the upcoming resource update.
As drilling continues, we’re accelerating our geological and structural modelling to better understand the evolving geometry of the system. Each new hole is refining our understanding of how the mineralization develops at depth and how the deposits relate to one another. That work is essential not only to support future resource growth, but also to ensure that conceptual redevelopment plans for the Selebi Mines Project will be based on the strongest possible geological understanding of the system.”

Detailed Drilling and BHEM Information
SMD-26-219, completed to 1958.5 metres is the most recent hole to intersect mineralization at the Flexure Zone. This hole was planned as a step-out in the direction of Selebi North and also tested the down-plunge extension of the interpreted trend of thick high grade massive sulphide mineralization.
SMD-26-219 intersected multiple intervals of massive, semi-massive and disseminated mineralization. The Main Zone is seen as a 20.0 metre wide weakly to moderately mineralized interval from 1858.50 to 1878.50 metres and contains two narrow intervals of massive sulphides. The lower zone is represented by a 7.55 metre mineralized interval containing a 6.60 metre interval dominated by massive sulphides.
The lower zone intersection represents the most significant interval of massive sulphides seen in the lower zone and the massive sulphide zone is similar to the lower zone intersection in SMD-26-213 (7.45 m of 2.52% Cu, 1.54% Ni, see news release July 22, 2026). The distance between these two holes is 175 metres.
The hole was surveyed with BHEM and results show a strong off-hole anomaly corresponding to the Main Zone that indicates a strong conductor immediately up-plunge. The lower Zone shows a large in-hole response with the conductor extending both down-dip and down-plunge toward Selebi North.

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.
Technical Report
The 2024 MRE on the Selebi Mines is supported by the technical report entitled “Technical Report, Selebi Mines, Central District, Republic of Botswana” dated September 20, 2024 (with an effective date of June 30, 2024) (the “Selebi Technical Report”), and the technical report summary entitled “S-K 1300 Technical Report Summary Selebi Mines, Central District, Republic of Botswana, Premium Resources Ltd.” dated December 17, 2024 (with an effective date of June 30, 2024) (the “Selebi Technical Report Summary”), each prepared by SLR Consulting (Canada) Ltd. for NEXM.
