Rhea-AI Filing Summary

NexMetals Mining Corp. reported a major upgrade to the Mineral Resource Estimate for its Selkirk copper-nickel-PGE project in Botswana. The 2026 estimate increases contained copper equivalent metal by about 63% and is described as a 70% increase in Selkirk’s mineral resource.

The updated model outlines approximately 1.1 billion pounds of copper equivalent (CuEq) in the Indicated category, based on 78.2 million tonnes grading 0.66% CuEq, and about 200 million pounds of CuEq in the Inferred category from 15.1 million tonnes grading 0.60% CuEq. The Indicated inventory now includes nickel, copper, cobalt, platinum, palladium, gold and silver.

Key drivers versus the 2024 estimate include improved metallurgical recoveries, adding cobalt, silver and gold as payable metals, and expanded sampling that supports a larger mineralized envelope and pit shell on a Net Smelter Return basis. The strip ratio falls to 1.02:1 from 1.65:1, among the lowest disclosed for copper development projects.

NexMetals highlights Selkirk’s potential to produce clean, separate copper and nickel concentrates meeting commercial smelter specifications and calls the project a strategically important, advanced-stage asset within its Botswana portfolio. A NI 43-101 Technical Report supporting the 2026 resource is expected to be filed on SEDAR+ and EDGAR within 45 days.

Positive

  • Major resource growth and de-risking at Selkirk: Contained copper equivalent inventory increases about 63% to roughly 1.1 billion pounds in the Indicated category and 200 million pounds in Inferred, with a substantial conversion from Inferred to Indicated resources and a much lower 1.02:1 strip ratio.
  • Improved metallurgy and multi-metal payabilities: Updated recoveries and inclusion of cobalt, silver and gold as payable metals, along with clean copper and nickel concentrates meeting commercial smelter specifications, strengthen Selkirk’s technical profile and potential project optionality.

Negative

  • Still no Mineral Reserves or proven economics: The disclosure emphasizes that Mineral Resources are not Mineral Reserves, that there are no Mineral Reserves at Selkirk, and that there is no demonstrated economic viability yet, so the project remains at the resource and study stage.

Insights

Large resource upgrade and risk reduction at Selkirk, but still at the resource stage.

NexMetals now reports about 1.1 billion pounds CuEq in the Indicated category and 200 million pounds in Inferred at Selkirk. This represents roughly a 63% increase in contained CuEq versus the 2024 estimate and a major shift from purely Inferred to largely Indicated resources.

The upgrade is driven by better metallurgical recoveries, adding cobalt, silver and gold as payable metals, and expanded sampling that enlarges the conceptual pit shell. A reduced strip ratio of 1.02:1 from 1.65:1 improves open-pit mining potential, and testwork indicates clean copper and nickel concentrates that meet commercial specifications.

The impact for investors depends on future work: a NI 43-101 Technical Report is expected within 45 days, and the company plans to assess options such as partnerships, a spin-out or advancing to an economic study. Mineral Resources are not Mineral Reserves, and the disclosure notes there are no Mineral Reserves at Selkirk, so economic viability still needs to be demonstrated.

Mineral Resource Estimate financial
"is pleased to announce an updated Mineral Resource Estimate (“2026 MRE”) for its Selkirk Project"
A mineral resource estimate is a calculated approximation of how much metal or mineral material likely exists in a particular deposit and where it sits underground, similar to estimating how many cookies are in a jar by peeking at the layers. It matters to investors because it provides a data-based starting point for judging a project's potential value, future production and risks, while not guaranteeing recoverable or profitable amounts.
Indicated mineral resources financial
"1.1 Billion Pounds of Copper Equivalent in the Indicated Category and 200 Million Pounds in Inferred Category"
Indicated mineral resources are quantities and qualities of a mineral deposit estimated with a reasonable level of confidence based on spaced sampling and analysis, sitting between a rough guess and a high-certainty measurement. For investors, they matter because they support preliminary economic studies and mine planning—think of them as a reasonably reliable shopping list for a recipe, useful for deciding whether to invest further but not yet proof that profitable extraction is guaranteed.
Inferred mineral resources financial
"Investors should not assume that any part or all of indicated mineral resources or inferred mineral resources will ever be converted"
An inferred mineral resource is an estimate of the quantity and grade of minerals in the ground based on limited sampling and geological information, where confidence is low and continuity is uncertain. For investors it signals potential value but also higher risk—like a rough sketch of a hidden treasure that requires much more exploration and testing before you can reliably judge its size or economic worth.
Net Smelter Return (NSR) financial
"Mineral Resources are reported at a cut-off value of US$25/t NSR (Net Smelter Return)"
A net smelter return (NSR) is a royalty payment equal to a fixed percentage of the money received from selling mined metals after they have been processed and refined; it’s calculated on the final proceeds rather than on the raw ore. For investors, NSRs matter because they create a predictable, passive revenue stream tied to metal sales—like receiving a slice of the final sale price after a craftsman turns raw material into a finished product—affecting valuation, cash flow and risk exposure to production and metal prices.
CuEq financial
"CuEq is calculated using the formula CuEq %)=91.4*Cu(%)+Ni(%)*(85.1/91.4)+Co(%)*(93.8/91.4)+Pt(g/t)*(22.4/91.4)"
CuEq (copper equivalent) converts the value of multiple metals in a mineral deposit into the amount of copper that would have the same value, producing a single, comparable grade number. For investors it acts like converting different currencies into one money — simplifying comparison of deposits and potential revenue, but its accuracy depends on the metal prices, recovery rates and cost assumptions used to make the conversion, so detailed reports are still needed.
NI 43-101 financial
"National Instrument 43-101 (“NI 43-101”) will be filed on SEDAR+ and EDGAR within 45 days"
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.

Item 7.01Regulation FD Disclosure.

 

On 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.

 

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.

NexMetals Increases Selkirk Mineral Resource by 70%,

Establishing 1.1 Billion Pounds of Copper Equivalent in the Indicated Category and 200 Million Pounds in Inferred Category

 

Indicated Resource Totals 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), Enhancing Scale and Open Pit Development Potential

 

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.

 

Next 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.

 

 

1 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.

FAQ

What did NexMetals Mining Corp. (NEXM) announce about the Selkirk Project?

NexMetals announced a 2026 Mineral Resource Estimate for its Selkirk Project in Botswana, increasing contained copper equivalent by about 63%. The update shifts much of the mineralization into the Indicated category and lowers the strip ratio, improving open-pit development potential.

How large is NexMetals’ updated Selkirk Mineral Resource in 2026?

The 2026 estimate outlines approximately 1.1 billion pounds of copper equivalent in the Indicated category and about 200 million pounds in Inferred. These are based on 78.2 million tonnes at 0.66% CuEq Indicated and 15.1 million tonnes at 0.60% CuEq Inferred, including nickel, copper, cobalt and PGEs.

How does the 2026 Selkirk Mineral Resource compare to NexMetals’ 2024 estimate?

The 2026 resource increases Selkirk’s contained copper equivalent metal inventory by roughly 63% versus the 2024 estimate. Previously, Selkirk had 789 million pounds of CuEq in the Inferred category only; the new model converts a significant portion into Indicated resources and expands the conceptual pit shell.

What grades and tonnages underpin NexMetals’ Selkirk Indicated resources?

Indicated resources total 78.2 million tonnes grading 0.66% CuEq. This includes 0.21% nickel, 0.23% copper, 0.012% cobalt, plus 0.10 g/t platinum, 0.42 g/t palladium, 0.05 g/t gold and 0.72 g/t silver, giving diversified exposure across multiple payable metals.

What mining and metallurgical improvements were highlighted for Selkirk?

The company reports significantly better metallurgical recoveries and inclusion of cobalt, silver and gold as payable metals. Testwork confirms the ability to produce separate, clean copper and nickel concentrates, and the strip ratio is reduced to 1.02:1 from 1.65:1, improving open-pit potential.

Does NexMetals’ Selkirk Project have Mineral Reserves or only resources?

Selkirk currently has Mineral Resources only, with no Mineral Reserves reported. The disclosure stresses that Mineral Resources are not Mineral Reserves and have no demonstrated economic viability, meaning further technical and economic studies are required before any production decision.

What are NexMetals’ next steps for the Selkirk Project after the 2026 MRE?

NexMetals plans to file a NI 43-101 Technical Report supporting the 2026 Mineral Resource within 45 days. The company expects to evaluate strategic options for Selkirk, including potential partnerships, a spin-out transaction, or advancing the project toward an economic study.
