7.01 Regulation

FD Disclosure.

On

September 23, 2026, NexMetals Mining Corp. (the “Company”) issued a news release reporting assay results from drill hole

SMD-26-219 and a new visual intercept from drill hole SMD-26-217, part of its ongoing surface drilling program 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.

Reports 7.55 Metres of 6.48% CuEq (2.70% Cu, 1.83% Ni) in SMD-26-219, Visual Intercept SMD-26-217 Intersects Three Mineralized Zones

and Extends High-Grade Trend to Approximately 1.5 Kilometres

Vancouver,

British Columbia, September 23, 2026 – NexMetals Mining Corp. (TSXV: NEXM) (Nasdaq: NEXM) (“NEXM”

or the “Company”) is pleased to report assay results from drill hole SMD-26-219 and a new visual intercept from drill

hole SMD-26-217, part of its ongoing surface drilling program at the Selebi Main deposit in Botswana (see Figure 1). The results continue

to support the Company’s data-driven exploration model and highlights the potential for continued growth of the Selebi Main mineralized

system.

SMD-26-219

returned 7.55 metres grading 6.48% CuEq (2.70% Cu and 1.83% Ni), confirming another thick, high-grade massive sulphide intersection along

an emerging high-grade trend that has now been defined over approximately 1.5 kilometres (the “High-Grade Trend”).

SMD-26-217

extended the High-Grade Trend by a further 100 metres toward Selebi North and intersected a combined total of 38.65 metres of disseminated

to massive sulphide mineralization across three zones. The hole represents the deepest significant intercept of mineralization along

the trend and confirmed the Main and Lower Zones, while also, for the first time, intersecting a Third Zone of massive sulphide mineralization

approximately 9 metres below the Lower Zone. Together, the three zones represent one of the thickest mineralized intervals encountered

during the program to date and provide further evidence that the High-Grade Trend continues laterally through the Flexure Zone toward

Selebi North. Assays are pending.

Why

This Matters

● Exceptional

grades continue to define the High-Grade Trend. SMD-26-219 returned 7.55 metres grading

6.48% CuEq, building on a series of thick, high-grade intersections and reinforcing the strength

and consistency of mineralization across the growing trend.

● The

Trend has been extended toward Selebi North. SMD-26-217 extended the interpreted High-Grade

Trend by approximately 100 metres to approximately 1.5 kilometres.

● Lower

Zone is demonstrating increasing continuity at depth. Results from SMD-26-213, which

returned 7.45 metres grading 5.69% CuEq (2.52% Cu, 1.54% Ni), and SMD-26-219, together with

the visual intercept in SMD-26-217, strengthen the interpretation of a laterally and vertically

extensive Lower Zone.

● The

Third Zone introduces a new dimension to the exploration model. Its discovery below the

Lower Zone indicates that the system is more complex than previously interpreted and creates

an additional target opportunity for potential expansion.

● Widely

spaced step-outs are rapidly building potential tonnage. Continued drilling success beyond

the 2024 Mineral Resource Estimate (“2024 MRE”) demonstrates the potential

for meaningful resource growth at Selebi Main, both within the upcoming 2026 Mineral Resource

Estimate (“2026 MRE”) and beyond its cut-off date.

● The

system remains open and recent BHEM indicates the High-Grade Trend continues. Borehole

electromagnetic surveying (“BHEM”) indicates that the High-Grade Trend

continues beyond SMD-26-217, supporting further potential laterally and down plunge. Ongoing

drilling and geological modelling will test the extent of all three mineralized zones and

target additional areas of thick massive sulphide mineralization.

1

Next

Steps

● The

2026 Mineral Resource Estimate (“2026 MRE”) remains on track for completion

in the third quarter of 2026. Drill holes completed after the resource cut-off date of September

21, including SMD-26-217, 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: “SMD-26-219 delivered another strong result, with 7.55 metres grading

6.48% CuEq. It is the latest in a series of successful, widely spaced step-out holes that are rapidly defining additional tonnage at

Selebi Main and extending this High-Grade Trend to approximately 1.5 kilometres.

SMD-26-217

extended the trend by a further 100 metres and, for the first time in this area, intersected a third zone of massive sulphide mineralization

below the Main and Lower Zone. The presence of three distinct mineralized zones highlights both the complexity of the Selebi Main system

and the significant potential that remains within the deposit and beyond the areas tested to date. BHEM surveying in SMD-26-217 is complete

and results indicate that the lower zone continues to depth.

The

2026 MRE continues to advance, and our Qualified Persons are working diligently to complete it. The additional time has allowed us to

incorporate results from SMD-26-219 that we believe will add meaningful tonnage and provide a more complete picture of the growth achieved

at Selebi Main. We look forward to sharing the 2026 MRE with the market upon its completion.”

Detailed

Drilling and BHEM Information

SMD-26-219,

completed to 1956.8 metres, was planned as a step-out hole in the direction of Selebi North and tested the down-plunge extension of the

interpreted trend of thick high grade massive sulphide mineralization. The hole intercepted Main Zone mineralization between 1858.50

to 1878.00 metres. The 19.50-metre-wide zone was dominated by disseminated sulphides including a total of 2.15 metres of massive sulphide

in two narrow intervals. The drillhole intercepted the Lower Zone between 1903.25 and 1916.75 metres. Within this 13.50 metre zone, is

a 7.55 metre interval dominated by semi-massive and massive sulphides. Mineralization at SMD-26-219 is very similar to that seen in SMD-26-213

175 metres away (7.45 m of 2.52% Cu, 1.54% Ni, news release July 22, 2026) and in the recently completed SMD-26-217 step out hole

located 100 metres toward Selebi North

SMD-26-217

was planned to be another down plunge step out hole, testing along the High-Grade Trend. The hole was completed to a final depth of 2050.9

metres. SMD-26-217 drilled three distinct zones of mineralization separated by short intervals of country rock between 1920.30 metres

and 2000.90 metres.

● Main

Zone - (1920.30 metres – 1941.15 metres): Spans a total mineralized interval

of 20.85 metres. The zone is dominated by 19.90m of weakly mineralised medium to coarse

grained amphibolite shist. Two sub-metre intervals, 0.80 meters and 0.15 meters, of massive

sulphide occur in the middle of the zone.

3

● Lower

Zone - (1974.75 metres – 1981.35 metres): Intersected a combined total of 5.00

metres of massive sulphides and 1.60 metres of disseminated sulphides, containing abundant

pyrrhotite, chalcopyrite, and magnetite crystals.

● Third

Zone - (1994.30 metres – 2000.90 metres): At 8.65 metres below the Lower Zone the

drill discovered a new mineralized horizon, featuring 2.30 metres of disseminated to semi-massive

mineralized amphibolite directly underlain by 4.30 metres of massive sulphide comprised

of pyrrhotite and chalcopyrite.

SMD-26-217

has not only extended the footprint of mineralisation by 100 metres, but it has also showed the mineralization thickening down plunge.

The third zone discovery shows that the Selebi Main deposit continues to dramatically change with each new drill hole highlighting the

potential in the flexure zone between Selebi Main and Selebi North (Figure 2).

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.

5

Quality

Control and Data Verification

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.

The

Qualified Person has verified the data through contribution to the core handling and sampling procedures, visits to the drill and core

processing facilities, monitoring of core logging results and sample selection, review of core assay and QAQC results.

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”),

mineral exploration and development industry; and those risks set out in the Company’s filings with the SEC on EDGAR (www.sec.gov)

and public disclosure record on SEDAR+ (www.sedarplus.ca), in each case, under NEXM’s issuer profile. Although the Company

believes that the assumptions and factors used in preparing the forward-looking information in this news release are reasonable, undue

reliance should not be placed on such information, which only applies as of the date of this news release, and no assurance can be given

that such events will occur in the disclosed time frames or at all. The Company disclaims any intention or obligation to update or revise

any forward-looking information, whether as a result of new information, future events or otherwise, other than as required by law.
