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

New drilling in the Flexure Zone accounts for 91% of the resource tonnage increase, while Selebi North remains outside the estimate.

Rhea-AI Summary

NexMetals Mining (NEXM) increased its Selebi Main inferred mineral resource estimate to 32.47 million tonnes, approximately 72% above the 2024 estimate. Effective September 28, 2026, the estimate grades 1.53% copper, 0.98% nickel and 0.05% cobalt. Contained copper rose 55% to 495,400 tonnes and contained nickel rose 91% to 316,800 tonnes. Cobalt is included for the first time, at 16,200 contained tonnes; total copper equivalent is 1,772 million pounds.

New Flexure Zone drilling accounts for 91% of the tonnage increase. Copper grade declined from 1.69%, while nickel grade increased from 0.88%. Selebi North's updated estimate remains pending and is excluded, as is step-out drilling completed after the data cutoff. NexMetals expects Selebi North results in the near term and will provide next-step guidance after completion. Cash was approximately $10.5 million at September 30.

4 terms

net smelter return technical

"US$75/t NSR (Net Smelter Return)"

Net smelter return is the percentage of revenue from selling a mineral or metal that a mining company or project owner receives after deducting costs like refining and transportation. It functions like a share of the profits from the mineral's sale, giving investors an idea of how much money the project generates. This measure helps investors assess the potential profitability of a mining asset.

ni 43-101 regulatory

"incorporated by reference into National Instrument 43-101"

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

ordinary kriging technical

"using ordinary kriging, and density was estimated"

Ordinary kriging is a statistical method for estimating an unknown value at a location by combining nearby measured values, giving more weight to closer and more closely related samples and producing a best-fit estimate plus a measure of uncertainty. Think of it as asking neighboring sensors or samples for their opinion and averaging them intelligently based on how correlated they are; investors use it to estimate quantities like mineral grades, oil reservoir properties, soil contamination, or spatially varying financial exposure and to gauge the reliability of those estimates.

icp-aes technical

"inductively coupled plasma atomic emission spectrometry (ICP-AES) finish"

ICP-AES (Inductively Coupled Plasma–Atomic Emission Spectroscopy) is a laboratory technique that identifies and measures the amounts of metals and other elements in a sample by turning the sample into a hot glowing gas and reading the light colors it emits—like using a prism to tell which ingredients are present and how much. Investors care because it provides reliable, quantitative proof of metal content, contamination levels or product purity, which affects resource valuation, regulatory compliance and product quality across mining, manufacturing and environmental contexts.

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--(Newsfile Corp. - 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.

Next 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 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.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

How much did NexMetals' Selebi Main mineral resource increase?

Selebi Main's inferred resource increased approximately 72% to 32.47 million tonnes, compared with 18.89 million tonnes in the 2024 estimate. Contained copper increased 55% to 495,400 tonnes, while contained nickel increased 91% to 316,800 tonnes.

When will NexMetals report the updated Selebi North resource estimate?

NexMetals expects to report the updated Selebi North estimate in the near term, following completion of the ongoing work. Selebi North is not included in the announced Selebi Main figures. Guidance on next steps will follow completion of the Selebi North estimate.

What price and recovery assumptions underpin NexMetals' Selebi Main resource estimate?

The estimate uses metal prices of US$5.10 per pound of copper, US$9.10 per pound of nickel and US$20.00 per pound of cobalt. Assumed recoveries are 96.1% for copper, 55.6% for nickel and 60.2% for cobalt, based on a two-concentrate scenario. Resources are reported above a US$75-per-tonne net smelter return cutoff, meaning recovered metal value minus off-site costs, with a minimum thickness of 1.5 metres.

Does NexMetals' updated Selebi Main estimate include silver, platinum or palladium?

Silver, platinum and palladium are not included in the updated resource estimate. Assay coverage for these metals does not extend across the full resource. Economic potential has not been established for the minor platinum and palladium concentrations.
