NexMetals Mining Corp.

In determining the Company’s material properties, management considered both quantitative and qualitative factors, assessed in the context of the Company’s overall business and financial condition. The Company concluded that, as of the date of the filing of this Report, the Company’s only material mining properties are the Selebi Mines and the Selkirk Mine. The Company will update its assessment of individually material mines on an annual basis.

While the Company also holds interests in certain exploration stage properties located in Canada, the Company has determined that such properties are not independently material to the Company at this time. For more information, see below under the heading “Canada Nickel Projects – Sudbury, Ontario”.

The information that follows relating to the Selebi Mines is derived from, and in some instances is an extract from, the Selebi TRS (as defined herein). Portions of the following information are based on assumptions, qualifications and procedures which are not fully described herein. Reference should be made to the full text of the Selebi TRS, which has been included as Exhibit 96.1 to this Report. In the event that we determine that any modifying factors, estimates and other scientific and technical information in the report materially change, we may update or file a new technical report in the future. The Selebi Mines is an exploration stage property.

Pursuant to Item 1302(b)(5) of Regulation S-K (17 C.F.R. §229.1302(b)(5)), the Company states that the Selebi TRS was prepared by SLR Consulting (Canada) Ltd (“SLR”). The qualified persons of SLR meet the qualifications specified under the definition of “qualified person” under Item 1300 of Regulation S-K.

Property Description and Location

The Selebi Mines are located in Botswana approximately 150 km southeast of the city of Francistown, and 410 km northeast of the national capital Gaborone. The Selebi Mines are readily accessed via paved and gravel roads from the town of Selebi-Phikwe, located just north of the mining licence. With a population of approximately 43,000, the town is accessed via a well-maintained paved road that branches due east from the major A1 highway at the town of Serule, 57 km from the Selebi Mines.

The Selebi Main deposit began production in 1980 and Selebi North began production in 1990. Mining terminated at both operations in 2016 due to weak global commodity prices and a failure in the separate Phikwe smelter processing facility. The BCL assets were subsequently placed under liquidation in 2017.

Mining Tenure

The Selebi Mines consist of a single mining licence covering an area of 11,504 hectares. The mining licence is centred approximately at 22°03’00”S and 27°47’00”E.

Mining licence 2022/1L was granted to PNRPL on January 31, 2022, over the Selebi Mines deposits discovered under mining licence 4/72. The original licence which had been granted to BCL on March 7, 1972, which covered both Selebi and Phikwe project areas, was amended several times and renewed once, and was set to expire on March 6, 2022. The current mining licence is limited to the Selebi and Selebi North deposits and their surrounding areas, expires May 26, 2032, and excludes the Phikwe mines and associated infrastructure.

-22-

Infrastructure

The historical BCL operations consisted of an integrated mining, concentrating and smelting complex which operated for over 40 years over the Selebi Phikwe project area. The smelter processed Selebi and Phikwe concentrates and toll treated nickel concentrates received from the Nkomati Nickel Mine and the Phoenix Mine. The concentrator plant and smelter were located adjacent to the Selebi Mines at the historical Phikwe Mine; however, these facilities were not included in the Company’s acquisition of the Selebi Mines and remain under separate ownership. Both facilities were placed on care and maintenance in 2016. The Selebi Mines current infrastructure includes two previously operating mines, Selebi Main (#2 Shaft) and Selebi North (#4 Shaft), and associated surface infrastructure.

History

Exploration in the Selebi Mines area was initiated in 1959 by Bamangwato Concessions Limited (“Bamangwato”) and included soil geochemistry, geological mapping, trenching, and diamond drilling over the then combined Selebi-Phikwe area. The Selebi and Phikwe discoveries were made in 1963 and 1967, respectively, and a single mining lease was granted to Bamangwato in 1967 covering both areas.

Bamangwato changed its name to BCL in 1977 and operated the combined Selebi-Phikwe project from 1970 until its closure in 2016. Nickel and copper ore was mined from an open pit at Phikwe (1971 to 1980), as well as four distinct underground production areas namely Phikwe (1981 to 2016), Southeast Extension (at Phikwe, 1997 to 2016), Selebi North (1990 to 2016) and Selebi (1980 to 2016). Head grades declined from 2010 to 2015 and in October 2016 BCL was placed into provisional liquidation and all its operations put under care and maintenance.

NEXM acquired the Selebi Mines and current Selebi mining lease from the BCL Liquidator on January 31, 2022.

Geological Setting, Mineralization and Deposit

The eastern portion of Botswana forms part of the Limpopo Mobile Belt (“LMB”) which represents a deep crustal section through an orogenic province between the Kaapvaal and Zimbabwe Cratons.

-23-

The Selebi Mines are located in highly deformed and metamorphosed Archean gneisses near the north margin of the central zone (“CZ”) of the LMB. The CZ region is characterized by complex structural fold patterns accompanied by regional and cataclastic metamorphism with grades ranging from amphibolite to granulite facies and cataclastic tectonites.

The deposits in the Selebi Mines area are categorized as ortho-magmatic nickel-copper sulphide-type deposits. They are hosted within amphibolite and understood as a tectono-metamorphically modified tholeiitic magma parents with an immiscible sulphide melt which has undergone all the phases of deformation that have affected the enclosing gneisses. They form part of the Selebi-Phikwe belt of intrusions that also contain the Phikwe, Dikoloti, Lentswe, and Phokoje deposits.

All mineralization horizons pinch and swell, are conformable to the gneissic foliation, and are hosted within or at the hanging wall contact of amphibolite with the gneissic country rocks. Mineralization horizons range in thickness from very thin to over 20 metres thick and are commonly one to three metres thick (deposit dependent). Orientation follows country rock foliation, and the zones can dip moderately to steeply, and can extend from 150 m to over 2,000 metres.

The principal sulphide minerals are pyrrhotite, chalcopyrite, and pentlandite which occur in massive, semi-massive, and disseminated form. Pyrite occurs as localized overgrowth. Magnetite occurs as rounded inclusions in massive sulphides and as later overgrowths.

Selebi Mines Mineral Resource Estimate, June 30, 2024:

The key assumptions, parameters, and methods used to estimate the mineral resources are contained in the Selebi TRS.Readers are cautioned not to assume that all or any part of Indicated Mineral Resources will ever be converted into Mineral Reserves as defined by S-K 1300. Readers are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally mineable, or that an Inferred Mineral Resource will ever be upgraded to a higher category.

Selkirk Mine

The information that follows relating to the Selkirk Mine is derived from, and in some instances is an extract from, the Selkirk TRS. Portions of the following information are based on assumptions, qualifications and procedures which are not fully described herein. Reference should be made to the full text of the Selkirk TRS, which has been included as Exhibit 96.2 to this Report. The Selkirk TRS is incorporated herein by reference and made a part hereof. In the event that we determine that any modifying factors, estimates and other scientific and technical information in the report materially change, we may update or file a new technical report in the future. The Selkirk Mine is an exploration stage property.

Pursuant to Item 1302(b)(5) of Regulation S-K (17 C.F.R. §229.1302(b)(5)), the Company states that the Selkirk TRS was prepared by SLR. The qualified persons of SLR meet the qualifications specified under the definition of “qualified person” under Item 1300 of Regulation S-K.

Property Description and Location

The Selkirk Mine is located in the northeast of Botswana approximately 28 km southeast of the city of Francistown, and 450 km northeast of the national capital Gaborone.

The property is accessed year-round via paved and gravel roads from Gaborone and Francistown. The Selkirk Mine infrastructure includes relict surface infrastructure supporting the historical underground mine, and the original decline. The Selkirk Mine has a fairly level terrain, and beyond the mine footprint is covered in grassland with dispersed and clusters of trees typical of a tree savanna biome.

Mining Tenure

The Selkirk Mine consists of a single mining licence covering an area of 1,458 hectares (14.58 km 2) and four prospecting licences covering a total of 12,670 hectares (126.7 km 2). The mining licence, 2022/7L, is centred approximately at 21°19’13” S and 27°44’17” E and is held by PNGPL, a subsidiary of NEXM. The mining licence was renewed for ten years commencing on May 27, 2022, ending on May 26, 2032. The four prospecting licences (PL050/2010, PL051/2010, PL210/2010, and PL071/2011) were renewed during the first quarter of 2025 and will expire March 31, 2027.

Infrastructure

The area is in a rural district, and the available infrastructure is minimal. The property benefits from power and water supply. A railway line crosses the western margin of the Selkirk area.

History

Anglo American Corporation of South Africa established the presence of nickel and copper occurrences at the sites of the ancient copper workings in the area in 1929. Significant exploration started in the mid-1960s by the Tati Territory Exploration Company. The first exploration campaigns included soil sampling, trench sampling, ground geophysics, and diamond drilling. At least four exploration and mining companies have worked on the Selkirk Mine since the 1960s and extensive work has been done to characterize the economic potential of the property.

The Selkirk underground mine was operated from 1989 to 2002 by TNMC, a company created specifically to exploit the deposit. More than 1 Mt of material grading 2.6% Ni and 1.6% Cu was extracted from a semi-elliptical deposit of massive sulphide up to 20 m thick. Since 2003, extensive exploration has been completed to characterize the lower-grade/higher-tonnage halo of disseminated sulphides both surrounding and down plunge (south) of the mined-out high-grade mineralization. Exploration and conceptual studies were conducted by Lion Ore Mining Pty Ltd and subsequently by Norilsk Nickel Group of Companies through their ownership in TNMC.

Geological Setting, Mineralization, and Deposit

The Selkirk Mine lies within the Tati granite-greenstone belt of the Zimbabwe Craton. The mineralized body of the Selkirk deposit is hosted within the Selkirk Formation (>1 km thick) which consists mainly of dacitic and rhyolitic volcaniclastic rocks and minor amounts of mafic volcanic rocks, quartzites, and quartz sericite schists. The Selkirk Formation hosts the Phoenix, Selkirk, and Tekwane meta-gabbronoritic intrusions and the Sikukwe meta-peridotite intrusion and the area around the project hosts intrusive magmatic nickel-copper-platinum group element sulphide deposits, namely the Phoenix deposit, as well as the Tekwane and Cinderella exploration prospects.

Two styles of mineralization are found at Selkirk: (1) massive sulphides (mined-out), located within the metagabbro intrusion as well as small, massive sulphide accumulations at the base of the taxitic metagabbro intrusive, and (2) matrix and disseminated sulphides as a halo surrounding and down-dip of the mined-out massive sulphide body. The disseminated zone that once included the mined-out sulphide lens, lies 50 m to 100 m above the basal contact of the footwall quartz diorite and mimics the footwall contact. Currently available drilling suggests that the shallow, previously mined, massive sulphide lens was synformal in shape and measured up to 70 m to 90 m wide, averaged 20 m thick, and had a plunge extent of 200 m.

The disseminated sulphide mineralization surrounding the massive sulphides is also synformal in shape, averages 120 m wide and 100 m to 150 m thick and plunges shallowly to the south at 25°. It is defined from surface over a distance of 900 m and remains open at depth. Mineralization consists of pentlandite, pyrrhotite, chalcopyrite and pyrite. At least three generations of dykes crosscut the mineralized metagabbro. Numerous faults traversing the deposit have been described in surface and underground mapping, none of which present significant displacement at the deposit scale. The Selkirk metagabbro host has been attributed an age of 2.7 Ga.

On January 31, 2025, the Company filed with the SEC on a Current Report on Form 8-K, the Selkirk MRE in conformance with S-K 1300 and Item 601(b)(96) Technical Report Summary, entitled “S-K 1300 Technical Report Summary, Selkirk Nickel Project, North East District, Republic of Botswana” and dated January 8, 2025 (with an effective date of November 1, 2024), for its Selkirk Mine.

The table below presents the Selkirk Mine Mineral Resource Estimate, with effective date of November 1, 2024:

The key assumptions, parameters, and methods used to estimate the mineral resources are contained in the Selkirk TRS.

Readers are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally mineable, or that an Inferred Mineral Resource will ever be upgraded to a higher category.

The Selkirk MRE provides a solid foundation for advancing the Selkirk deposit to an economic study. It was prepared using results from 232 surface and 10 underground historical drillholes drilled between 2003 and 2016, five 2016 drillholes sampled by NEXM in 2021, and 17 historical drillholes resampled in 2024. Analytical results from NEXM re-sampling showed higher platinum group element values compared to historic results. Cobalt, a potentially valuable by-product, has not been included in the Selkirk MRE as cobalt analyses were not consistently available throughout the deposit at the time of MRE preparation. Ongoing metallurgical studies will determine payability of cobalt at the Selkirk Mine.

Canadian Nickel Projects - Sudbury, Ontario

Post Creek Property

The Post Creek property is located 35 kilometres east of Sudbury in Norman, Parkin, Alymer and Rathburn townships and consists of 64 unpatented mining claim cells, covering a total area of 847 hectares held by the Company. The Company acquired the property through an option agreement in April 2010, which was subsequently amended in March 2013. As at the date of this Report, the Company holds a 100% interest in the Post Creek property and is obligated to pay advances on a net smelter return of $10,000 per annum, which will be deducted from any payments to be made under the net smelter return.

The Post Creek property lies adjacent to the Whistle Offset Dyke Structure which hosts the past–producing Whistle Offset and Podolsky Cu-Ni-PGM mines. Post Creek lies along an interpreted northeast extension of the corridor containing the Whistle Offset Dyke and Footwall deposits and accounts for a significant portion of all ore mined in the Sudbury nickel district and, as such, represents favourable exploration targets. Key lithologies are Quartz Diorite and metabreccia related to offset dykes and Sudbury Breccia associated with Footwall rocks of the Sudbury Igneous Complex which both represent potential controls on mineralization.

No exploration work was completed in 2025 on the Post Creek property. The claims have sufficient work credits to keep them in good standing until 2030. No material expenditures or activities are currently being contemplated on the Post Creek property.

Halcyon Property

The Halcyon property is located 35 kilometres northeast of Sudbury in the Parkin and Aylmer townships and consists of 62 unpatented mining cells for a total of 1,024 hectares. Halcyon is adjacent to the Post Creek property and is approximately two kilometres north of the Podolsky Mine. The property was acquired through an option agreement and as at the date of this Report, the Company holds a 100% interest in the Halcyon property and is obligated to pay advances on a net smelter return of $8,000 per annum, which will be deducted from any payments to be made under the net smelter return.

No exploration work was completed on the Halcyon property in 2025. The claims are in good standing through 2030. No material expenditures or activities are currently being contemplated on the Halcyon property.

Maniitsoq Nickel-Copper-PGM Project, Southwest Greenland

Internal Controls over the Mineral Resources Estimation Process

The Company uses an industry-standard approach to exploration and mineral resource estimation that results in reasonable and reliable estimates aligned with industry practice and reporting regulations. The Company’s systems cover exploration activities, sample preparation and analysis, mineral processing, metallurgical testing, recovery estimation, and mineral resource estimations. Controls include, but are not limited to, use of certified laboratories, formal quality assurance and quality control (“QA/QC”) protocols, standardized procedures, workflow processes, data verification, supervision and management approval, internal and external reviews, and data security covering record keeping, chain of custody and data storage.

QA/QC protocols over sampling and assaying of drill hole samples encompass the insertion of blind reference material samples including certified reference materials (CRM) and blanks, as well as coarse reject duplicate samples in the primary sample streams. Selective pulp samples are analyzed at a secondary laboratory. All results are reviewed upon receipt and actioned according to predefined failure criteria. Internal reports are prepared to monitor performance and trends over longer periods.

Data is maintained in an industry standard data management software with regular backups and internal controls. Prior to use in mineral resource estimation, a third-party check verifies the drill hole database against laboratory sourced analytical certificates and validates the data through several standard and specific tests, including review of QA/QC results.

The mineral resource estimate is prepared by a third party whose standard workflow includes rigorous internal peer and senior review processes that consider the suitability of technical and economic inputs and assumptions, the geological framework, mineralizing system, and interpolation and classification approaches and execution. Results are reviewed internally by Company management.
