7.01 Regulation

FD Disclosure.

October 1, 2026, NexMetals Mining Corp. (the “Company”) issued a news release reporting an updated Mineral Resource Estimate

for Selebi Main, one of the deposits at its past-producing Selebi copper-nickel-cobalt mine 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.

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 72% Increase in Selebi Main Mineral Resource of 32.47 Mt @ 1.53% Cu, 0.98% Ni Inferred, Selebi North Mineral Resource Estimate

Pending

Updated

Selebi Main mineral resource estimate establishes 495,400 contained tonnes of copper and 316,800 contained tonnes of nickel establishing

1.77 billion pounds of copper equivalent in the Inferred category

Selebi

North estimate remains in progress and is not included in today’s results

Vancouver,

British Columbia, October 1, 2026 – NexMetals Mining Corp. (TSXV: NEXM) (Nasdaq: NEXM) (the “Company” or

“NexMetals”) is pleased to announce an updated Mineral Resource Estimate for Selebi Main (the “2026 Selebi

Main MRE”), one of the deposits at its past-producing Selebi copper-nickel-cobalt mine in Botswana. The estimate was completed

by The MSA Group (“MSA”) of Johannesburg, South Africa. The 2026 Selebi Main MRE increases total Mineral Resource

tonnage by approximately 72% compared with the Selebi Main portion of the Company’s 2024 Mineral Resource Estimate (the “2024

MRE”). The updated Mineral Resource Estimate for Selebi North is progressing, with results expected to be reported separately

in the near term, following completion of the ongoing work. No Selebi North mineral resources are included in the figures announced today.

Highlights:

●

72%

Growth in the 2026 Selebi Main MRE. The 2026 Selebi Main MRE increased to 32.47 million tonnes, grading 1.53% copper

and 0.97% nickel compared with 18.89 million tonnes grading 1.69% copper and 0.88% nickel in the 2024 MRE, with substantial increases

in contained copper and nickel, including:

○

55%

increase in contained copper to 495,400 tonnes, from 319,200 tonnes in 2024.

○

91%

Increase in contained nickel to 316,800 tonnes, from 165,500 tonnes in 2024.

○

Cobalt

is now included in the 2026 Selebi Main MRE, adding a third reported metal to the mineral resource estimate.

●

Resource

tonnage growth: 91% of the increase is attributable to new drilling in the Flexure Zone.

●

Updated

technical inputs. The 2026 Selebi Main MRE reflects updated metal price assumptions of US$5.10/lb Copper and US$9.10/lb nickel

and incorporates previously reported metallurgical results demonstrating the ability to produce separate, clean copper and nickel

concentrates that meet commercial smelter specifications.

●

Further

growth potential. Recent step-out drilling completed after the mineral resource cut-off date intersected thick, high-grade massive

sulphide mineralization. Those results are not included in the 2026 Selebi Main MRE.

Steps:

●

Selebi

North Mineral Resource Estimate is Nearing Completion. The Selebi North Mineral Resource Estimate is being finalized and will

be reported once complete. Together with the 2026 Selebi Main MRE announced today, it will provide a more comprehensive view of the

mineral resource and overall scale of the Selebi Mines.

Sean

Whiteford, CEO of the Company, commented: “The updated Selebi Main estimate is a major milestone for NexMetals. Resource growth,

driven primarily by new drilling in the Flexure Zone, exceeded our expectations and provides a stronger foundation for the next phase

of technical work. Given the scale of the increase, we are reporting the Selebi Main Mineral Resource Estimate while MSA completes its

work on Selebi North, which is not included in today’s figures. Consistent with Selebi Main, our drilling at Selebi North has been

highly successful, delivering significant intercepts down plunge and beyond Selebi North’s 2024 mineral resource envelope. These

results support our expectation of growth in the Selebi North resource, and we are optimistic that its forthcoming estimate will further

demonstrate the size and scale of the Selebi Mines.

“Selebi

Main also remains open beyond the limits of this estimate. Step-out drilling completed after the resource cut-off date has intersected

thick, high-grade massive sulphide mineralization. Our data driven approach of using BHEM to guide our drilling has been tremendously

successful and supports further growth potential both in down-dip and down-plunge directions. We continue to maintain a strong treasury

position, with an approximate cash balance of $10.5 million at September 30th, supporting our ability to advance the next phase of work.

Once the Selebi North Mineral Resource Estimate is complete, we will provide guidance on next steps.”

Mineral

Resources, which are not Mineral Reserves, have no demonstrated economic viability. There is no guarantee that all or any part of

the Mineral Resource will be converted into a Mineral Reserve. The estimate of Mineral Resources may be materially affected by geology,

environment, permitting, legal title, taxation, socio-political, marketing, or other relevant issues.

= thousand tonnes, Mt = Million tonnes, Mlbs = million pounds

The

2026 MRE has been prepared in accordance with the CIM Definition Standards (2014) and CIM Best Practice Guidelines (2019) with a

data cut-off of September 21, 2026, and an effective date of September 28, 2026.

Mineral

Resources are reported at a cut-off value of US$75/t NSR (Net Smelter Return) defined as received value of final metal recovered

minus off-site costs, and a minimum thickness of 1.5 metres.

Mineral

Resources are estimated using long-term prices of US$9.10/lb Ni, US$5.10/lb Cu, US$20.00/lb Co. The same metal prices were used in

NSR calculations.

Mineral

Resources are estimated using nickel, copper and cobalt recoveries of 55.6%, 96.1%, and 60.2%, respectively, derived from metallurgical

studies which consider a two-concentrate scenario.

Payabilities

and off-site treatment and refining costs were derived from an independent marketing study commissioned by NexMetals.

Bulk

density has been estimated in the block model based on an extensive data set of measurements taken from drillhole cores. The average

density is 3.51 t/m3 for the Upper vein and 3.38 t/m3 for the Lower vein.

Mineral

Resources are reported using NSR values which assume mining costs of US$47.60/tonne, concentrate processing costs of US$20.00/tonne

and G&A of US$5.50/tonne.

Mineral

Resource Data and Quality Control

The

historical sampling data collected by the previous owner and operator, BCL Limited (“BCL”) included Ni and Cu assays and

selective Co assays. The historical data was verified by NEXM through drilling of new holes between historical holes, which intersected

mineralization in the expected position, and a twin intercept from a wedge from one BCL surface hole. The data compared within reasonable

limits given the variability of the mineralization.

The

geological database used in the MRE comprises sixty-nine (69) historical (BCL) surface drillholes and 38 NEXM drillholes, including the

extension of 6 BCL drillholes, and 171 underground drillholes drilled by BCL during mining operations that were selected by MSA from

a larger underground drilling dataset to be representative of the mineralization in and close to the mined-out areas.

The

BCL assays were completed at the BCL Phikwe Laboratory. At the time of preparation and analysis, the BCL-owned laboratory was not independent

of the operator and accredited only for high grade matte analyses, but not for exploration grade analyses. Ni and Cu were analysed by

flame atomic absorption spectrometry. Relative density measurements were obtained by water immersion method.

The

NexMetals drill core was logged, photographed and marked for sampling in nominal lengths of one metre. The core samples were cut in half

longitudinally using a rotating diamond saw. The core samples were given a unique sample reference number, bagged and despatched to ALS

Laboratories Ltd. in Johannesburg, South Africa for analysis (SANAS Accredited Testing Laboratory, No. T0387). Samples were analysed

for Ni, Cu, and Co using a peroxide fusion preparation and inductively coupled plasma atomic emission spectrometry (ICP-AES) finish (ME-ICP81).

Analyses for Pt, Pd, and Au were by fire assay (30 g nominal sample weight) with an ICP-AES finish (PGMICP23), also by ALS. Ag was analysed

using a 4-acid digest and ICP-AES finish (ME-ICP61). Specific gravity measurements were also completed by ALS on pulps of selected samples.

The

NexMetals drilling was subjected to a comprehensive programme of quality assurance and quality control by NexMetals, independent of the

laboratories’ own QAQC measures, including certified reference materials (5%), blank samples (5%), coarse duplicate samples (5%)

and pulp duplicate samples (5%). The Qualified Person, Mr. J.C. Witley (BSc Hons, MSc (Eng.)), is satisfied that the assay results are

of sufficient accuracy and precision for use in Mineral Resource estimation.

Mineral

Resource Estimate

The

2026 Selebi Main MRE was completed by The MSA Group in Johannesburg, South Africa.

The

Mineral Resource was estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Best Practice Guidelines and is

reported in accordance with the 2014 CIM Definition Standards, which have been incorporated by reference into National Instrument 43-101

– Standards of Disclosure for Mineral Projects (“NI 43-101”).

The

deposit can be described as a metamorphosed magmatic nickel-copper sulphide deposit. Mineralization at Selebi Main comprises massive,

semi-massive and disseminated sulphides contained within a unit of amphibolite that is surrounded by undifferentiated quartzo-feldspathic

and mafic gneisses. Two mineralized zones have been interpreted, known as the Upper Vein and the Lower Vein, which are separated by barren

gneiss. The Upper Vein is generally the most continuous, whereas the Lower Vein is not developed over the entire area of the Upper Vein.

The veins reach thicknesses of up to 35 metres and can narrow to 10’s of cm and pinch out locally. The veins have an average true

thickness of approximately 7 metres for each vein. The deposit is broadly tabular with a strike length of between 1,500 m in the shallower

areas to 2,500 m at depth and NEXM drilling intersected nickel-copper sulphides at depths of up to approximately 1,950 m below surface.

Stoping has depleted the Mineral Resource from near surface to between 800 m and 1,000 m below surface. The deposit dips to the southwest

at an average of 40 degrees, however, local dip variability was commonly experienced in the prior mining areas.

Cobalt

and silver occur within the nickel-copper sulphide mineralization, with sufficient cobalt data to include in the MRE; however silver

assays are not available over much of the Mineral Resource extent and have not been included in the MRE. Minor concentrations of platinum

and palladium occur within the nickel-copper sulphide mineralization for which economic potential has not been established and, similarly

to silver, platinum and palladium assays do not cover the full extent of the Mineral Resource. Sulphide mineralogy is primarily pyrrhotite,

chalcopyrite and pentlandite.

All

recent exploration at the project, since the closure of the mine, was completed by NEXM in 2022 and 2023, and from 2025 to 2026 and is

ongoing. All prior exploration work of relevance to the MRE was completed by the previous operator, BCL Ltd (BCL) up until 2016. The

drilling completed since the 2024 MRE allowed for refinement of the previous interpretation and extension to the previously defined resource

area. The cut-off date for inclusion of data in this MRE is 21 September 2026.

Geological

modelling was undertaken in Datamine Studio RM utilising implicit vein modelling. Upper and Lower veins were coded into the surface and

underground drillhole data based on thickness, lithology and grade. Vein intercepts were selected based on an approximate threshold Net

Smelter Return (NSR) value of US$70/t using nickel, copper and cobalt grades, while ensuring geological continuity between closely spaced

intercepts. A minimum thickness of 1.5 metres was used to allow for a potential minimum mining width, and in some cases dilution outside

the mineralized vein was included. Variography was completed using Datamine Supervisor software. Ellipsoids were orientated in the plane

of mineralization with slight anisotropy along the mineralization plunge. Nickel, copper, and cobalt grades were interpolated into a

rotated block model with a parent cell size of 20 mX by 20 mY by 2 mRL using ordinary kriging, and density was estimated using inverse

distance squared. The Datamine process of “Dynamic Anisotropy” was used to modify the search ellipse to changes in the vein

orientation. Volumes representing mined voids were removed and a single modelled dyke was assigned grades of zero. NSR was then calculated

for each block model cell using the estimated grades, metal prices, recoveries, off-site costs and payabilities. The mineral resource

model was classified into the Inferred category, taking into account data quality, geological modelling uncertainty, drillhole spacing

and kriging outputs. The majority of the Inferred Mineral Resource is informed by drillholes with an approximate spacing of 200 metres

or significantly less close to the mined areas. The Mineral Resource extent was extrapolated a maximum of 100 metres along strike, 150

metres down plunge or the lesser of halfway to a below threshold intercept.

The

Mineral Resource was reported using am NSR grade above US$75 and a minimum thickness of 1.5 metres. Using concentrate costs of US$20/tonne,

G&A of US$5.50 per tonne, mining costs of US$47.6 and royalites of 3% for base metals the Mineral Resource satisfies cut-off grade

criteria and the QP considers that reasonable prospects for eventual economic extraction (RPEEE) for the Mineral Resource have been demonstrated.

Mineral

resources are not mineral reserves and do not have demonstrated economic viability. The estimate of mineral resources may be materially

affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. There is no certainty

that any mineral resources will be converted into mineral reserves. The quantity and grade of reported Inferred resources in the 2026

Selebi Main MRE are uncertain in nature, there has been insufficient exploration to define these Inferred resources as an Indicated or

Measured mineral resource, and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral

resource category.
