Item 7.01 Regulation

FD Disclosure.

June 24, 2026, NexMetals Mining Corp. (the “Company”) issued a news release announcing an updated Mineral Resource Estimate

for its Selkirk Project 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.

Vancouver,

British Columbia, June 24, 2026 – NexMetals Mining Corp. (TSXV: NEXM) (Nasdaq: NEXM) (the “Company”

or “NEXM”) is pleased to announce an updated Mineral Resource Estimate (“2026 MRE”) for its Selkirk

Project (“Selkirk” or the “Project”) in Botswana. Selkirk is a past-producing copper-nickel-platinum

group elements (“PGEs”) project located approximately 75 kilometres northeast of the Company’s flagship Selebi

Project. The 2026 MRE, completed by The MSA Group (“MSA”) in Johannesburg, South Africa, increases the Project’s

contained copper equivalent (“CuEq”) metal inventory by approximately 63% and reflects a significant conversion of

Mineral Resources from the Inferred to Indicated category following a successful re-assaying and twin drilling campaign. The 2026 MRE

represents an important technical milestone for the Selkirk Project, enhancing resource confidence and reducing development risk.

Highlights:

● Approximately

1.1 billion pounds of CuEq Mineral Resources in the Indicated category with 78.2 Mt grading

0.66% CuEq (0.21% Ni, 0.23% Cu, 0.012% Co, 0.10 g/t Pt, 0.42 g/t Pd, 0.05 g/t Au and

0.72 g/t Ag).

● Approximately

200 million pounds of CuEq Mineral Resources in the Inferred category with 15.1 Mt grading

0.60% CuEq (0.18% Ni, 0.21% Cu, 0.010% Co, 0.09 g/t Pt, 0.40 g/t Pd, 0.05 g/t Au and

0.77 g/t Ag).

● Key

drivers of the increase from the 2024 Mineral Resource Estimate (the “2024 MRE”)

include:

○ Significant

improvement in metallurgical recoveries resulting in higher expected payabilities;

○ Inclusion

of cobalt, silver and gold as payable metals, none of which were assigned value in the 2024

MRE due to limited assaying; and

○ Expanded

platinum, palladium, silver, cobalt and gold datasets from the historical core resampling

program, supporting an expanded mineralized envelope and larger conceptual pit shell on a

Net Smelter Return (NSR) basis.

● Metal

price changes had a minimal net impact relative to the 2024 MRE, reflecting Selkirk’s

diversified polymetallic metal mix, which provides exposure to multiple payable metals while

reducing single-commodity price risk.

● The

2026 MRE incorporates the previously reported metallurgical results (see news releases dated

April 27, 2026, and June 4, 2026) that confirm the ability to produce separate, clean copper

and nickel concentrates that meet commercial smelter specifications, further de-risking the

project.

● Strip

ratio reduced to 1.02:1 from 1.65:1, among the lowest strip ratios for copper development

projects globally, resulting from the inclusion of additional tonnage sitting above and adjacent

to the 2024 MRE.

Why

This Matters:

● Selkirk

has evolved into a strategically important, multi-commodity critical metals asset with the

scale and development potential to drive additional value creation for shareholders.

● Previously

assigned limited value as a secondary asset within the portfolio, the substantial conversion

to Indicated resources, clean concentrate quality and favourable open-pit mining characteristics

position Selkirk as a meaningful contributor to NexMetals’ future growth and support

a potential accelerated path toward pre-feasibility.

Steps:

● A

Technical Report prepared in accordance with National Instrument 43-101 (“NI 43-101”)

will be filed on SEDAR+ and EDGAR within 45 days of this news release.

● The

Company expects to evaluate a range of strategic options for Selkirk, including potential

partnerships, a spin-out, or advancement toward an economic study.

Sean

Whiteford, CEO of the Company, commented: “The 2026 MRE highlights the value embedded within our Botswana portfolio and reinforces

Selkirk as a strategically important asset for the Company. Through targeted drilling, re-assaying and metallurgical work, we have established

over 1.1 billion pounds of contained copper equivalent in the Indicated category. Importantly, this value was unlocked with relatively

modest investment, highlighting both the quality of the asset and the opportunity that remains ahead. Selkirk is an advanced-stage, past-producing

Project with open-pit development potential and the ability to produce clean saleable concentrates. As the most advanced asset in our

portfolio, it represents a compelling development opportunity and an important source of future value creation.”

“When

we acquired the Selebi and Selkirk projects out of liquidation in 2022, we saw an opportunity to unlock value through modern exploration

and disciplined technical work, and today’s resource update at Selkirk is a strong example of that strategy in action. At the same

time, we continue to advance our flagship Selebi project through drilling, with an updated Mineral Resource Estimate and Preliminary

Economic Assessment expected later this year. Together, these milestones should continue to demonstrate the scale, quality and growth

potential of our Botswana portfolio.”

Notes:

1. All

tabulated data have been rounded and as a result minor computational errors may occur.

2. Mineral

Resources, which are not Mineral Reserves, have no demonstrated economic viability. There

is no guarantee that 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.

3. kt

= thousand tonnes, Mlbs = Million pounds, koz = thousand ounces.

4. The

2026 MRE has been prepared in accordance with the CIM Definition Standards (2014) and CIM

Best Practice Guidelines (2019) with an effective date of June 22, 2026.

5. Mineral

Resources are reported at a cut-off value of US$25/t NSR (Net Smelter Return) defined as

received value of final metal recovered minus off-site costs.

6. Mineral

Resources are estimated using long-term prices of US$9.10/lb Ni, US$5.10/lb Cu, US$20.00/lb

Co, US$1,800/oz Pt, US$1,550/oz Pd, US$3,600/oz Au and US$52.00/oz Ag. The same metal prices

were used in CuEq and NSR calculations.

7. Mineral

Resources are estimated using nickel, copper, cobalt, platinum, palladium, gold and silver

recoveries of 54%, 88%, 53%, 56%, 78%, 72% and 61%, respectively, derived from metallurgical

studies which consider a two-concentrate scenario.

8. Payabilities

and off-site treatment and refining costs were derived from an independent marketing study

commissioned by NexMetals.

9. The

CuEq value was calculated based on relative recovered value received for each metal excluding

costs. Received value for each metal was calculated using the formula: in-situ grade*concentrator

recovery*payability*metal price. The ratio between received copper value and total other

metal value was then used to calculate CuEq, i.e., CuEq = (1+value excluding Cu / Cu value)

* Cu grade.

10. Bulk

density has been estimated in the block model based on an extensive data set of measurements

taken from drillhole cores.

11. Mineral

Resources are reported within an optimized pit shell using NSR values, mining cost of US$3/tonne

(additional US$0.008 per metre depth from pit rim), concentrate costs of US$20/tonne, G&A

of US$1.35 per tonne, 45°pit slope to base of partially weathered and 60° in fresh

rock.

12. There

are no Mineral Reserves.

Figure

1: 3D Block Model of the Selkirk Deposit highlighting the 2026 MRE and against the old open pit shell

The

3D block model highlights the significant advancement of the Selkirk Project through the 2026 MRE. The previous Selkirk Mineral Resource

Estimate comprised 789 million lbs of CuEq1 in the Inferred category with 44.2 Mt grading 0.81% CuEq (0.30% Cu, 0.24% Ni,

0.55 g/t Pd and 0.12 g/t Pt), entirely within the Inferred category. The updated model demonstrates a substantial increase in resource

confidence through the conversion of a significant portion of the mineralization to the Indicated category. The model also illustrates

a materially expanded conceptual open-pit shell relative to the 2024 MRE, reflecting increased contained metal.

Mineral

Resource Data and Quality Control

The

historical sampling data collected by the previous owner and operator, Tati Nickel Mining Company (“TNMC”), which

included Ni and Cu assays and selective Pd, Pd and Au assays. The historical data was verified through completion of eleven twin diamond

drillholes and approximately 6,000 samples taken for assay from the remaining TNMC core by NexMetals. Resampling included intervals previously

sampled by TNMC, as well as some extension sampling, and included a full suite of elements including Ni, Cu, Co, Pt, Pd, Au and Ag. Statistical

checks completed by MSA revealed no material bias between the historical and recent sample assays.

CuEq% calculated using the formula Cu% + Ni%*(55.605/53.913) + Pd g/t*(22.948/53.913) + Pt g/t*(14.891/53.913) using metal prices and

recoveries as per the 2024 Mineral Resource Estimate. See news release dated November 27, 2024.

Data

from drillholes completed prior to TNMC, as well as TNMC underground drilling and channel sampling, was not verifiable and was not included

in the 2026 MRE. A total of 216 diamond drillholes were used to estimate the 2026 MRE, including the TNMC drillholes, NexMetals twin

drilling and an infill drillhole completed by NexMetals.

The

TNMC assays were completed at the TNMC Phoenix Laboratory. At the time of preparation and analysis, TNMC owned both the Phoenix Mine

and Selkirk, and the laboratory was not independent of the operator. From 2011, the Phoenix Mine Laboratory held accreditation with the

South African National Accreditation System (SANAS), and with the International Organization for Standardization/International Electrotechnical

Commission (ISO/IEC) 17025 for chemical analyses. Ni and Cu were analysed by XRF and Pt, Pd and Au by 50 g lead collection fire assay.

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 bagged 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. A suite of

48 elements, including Ag, was analysed using a 4-acid digest and ICP-AES finish (ME-ICP61). Specific gravity measurements were also

completed by ALS.

The

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

of the laboratories’ own QA/QC 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

Selkirk Mineral Resource Estimate 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 NI 43-101.

The

Selkirk Mineral Resource is contained within the Selkirk Meta Gabbro, which is a massive roughly sub-vertical body plunging at a moderate

dip to the south-southwest approximately 300 to 450 m wide and has been intersected by drilling from surface to over 500 m deep. Sulphide

mineralisation consists primarily of disseminated pyrrhotite and chalcopyrite and veins and pods of massive sulphide. The Selkirk Meta

Gabbro has been intruded by several phases of later dykes which are barren.

Estimation

comprised modelling of the Selkirk metagabbro, dykes and a surface representing the base of oxidation, followed by the construction of

an implicit probability mineralised shell within the metagabbro including drillhole sample intervals greater than an NSR value of US$20.

A three-dimensional block model with parent cells of 20 mX by 20mY by 10mRL and appropriate sub-celling was used to estimate metal grades

and density by ordinary kriging. Volumes representing mined voids and oxidised material were removed and dykes were 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 Indicated and Inferred categories, taking into account data quality, geological modelling

uncertainty, drillhole spacing and kriging outputs. The majority of the Indicated Mineral Resource is informed by drillholes closer than

60 m apart up to maximum spacing of 75 m.

The

Mineral Resource was reported using a NSR based optimised pit-shell. Using concentrate costs of US$20/tonne, G&A of US$1.35 per tonne

and royalites of 3% for base metals and 5% for precious metals, blocks that occur within the pit-shell with estimated NSR above US$25/tonne

satisfy cut-off grade criteria and, together with the optimised pit shell, the QP considers that reasonable prospects for eventual economic

extraction (RPEEE) for the Mineral Resource have been demonstrated.

Qualified

Persons

Mr.

J.C. Witley (BSc Hons, MSc (Eng.)) is a geologist with more than 35 years’ experience in base and precious metals exploration and

mining as well as Mineral Resource evaluation and reporting. He is Head of Mineral Resources for The MSA Group (an independent consulting

company), is registered as Pr.Sci.Nat. with the South African Council for Natural Scientific Professions (SACNASP) and is a Fellow of

the Geological Society of South Africa (GSSA). Mr. Witley has the appropriate relevant qualifications and experience to be considered

a “Qualified Person” for the style and type of mineralisation and activity being undertaken as defined in NI 43-101 and is

considered independent of NexMetals pursuant to NI 43-101. Mr. Witley has reviewed and approved the technical and scientific information

within this news release pertaining to the Mineral Resource Estimate.

Verification

included a site visit by the QP to inspect historical mineralized core, observe existing infrastructure, including the Selkirk underground

ramp and remains of massive sulphide stockpiles at surface, and inspect several surface drillhole collar locations (both historical and

recent). The mineralisation in five of the twin holes was inspected by the QP. In addition, a selection of samples collected by NexMetals

have been verified against independently accessed assay certificates, and a random selection of historical database results have been

compared against digital records.

The

scientific and technical content of this news release has been reviewed and approved by Sharon Taylor, V.P. Exploration of the Company,

MSc, P.Geo, who is a “qualified person” for the purposes of NI 43-101.

Technical

Report

The

2026 MRE on Selkirk will be supported by a National Instrument 43-101 Technical Report to be filed within 45 days of this news release.
