Item 7.01 Regulation FD Disclosure.

On June 30, 2025, NexMetals Mining Corp. (the “Company”) issued a press release, which is attached as Exhibit 99.1 hereto.

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.

In accordance with General Instruction B.2 of Form 8-K, the information in Item 7.01 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 subject to the liability of that section, and shall not be incorporated by reference into any of the Company’s filings or other documents filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

Exhibit 99.1

NEXMETALS DRILLS 13.50 METRES OF 3.68% CUEQ EXPANDING MINERALIZATION SIGNIFICANTLY BELOW SELEBI NORTH

RESOURCE FOOTPRINT

Vancouver, British Columbia, June 30, 2025 – NexMetals Mining Corp. (TSXV: NEXM) (OTC Pink: PRMLD) (the “Company” or “NEXM”) is pleased to report assay results from the first two 2025 resource expansion holes with continued drilling at Selebi North Underground (“SNUG”) beyond the 2024 Mineral Resource Estimate (“MRE”).

Key Highlights:

● SNUG-25-184: South Limb, 183 metres down plunge of 2024 MRE 13.50 metres of 3.68% CuEq (1.13% Cu, 1.24% Ni, 0.06% Co) and N2 Limb, 300 metres down plunge of 2024 MRE 6.25 meters of 2.16% CuEq (0.62% Cu, 0.75% Ni, 0.04% Co)

● SNUG-25-185: N2 Limb, 65 metres down dip of 2024 MRE 5.95 metres of 4.14% CuEq (2.87% Cu, 0.62% Ni, 0.03% Co)

● A Borehole Electromagnetic (“BHEM”) survey completed in SNUG-25-184 revealed strong off-hole conductors, confirming the South Limb and N2 zones remain open down-plunge (see news release May 1, 2025).

● Follow-up hole SNUG-25-186 was drilled to test these conductors and interested 16.20 metres of South Limb mineralization 132 metres down-plunge of SNUG-25-184 (see news release May 27, 2025).

● South Limb mineralization has been extended 315 metres down-plunge beyond the 2024 resource model, based on holes SNUG-25-184 and 186. Assays for additional holes are pending.

● New mineralization discovered in recently completed drill hole SNUG-25-189 includes 5.20 metres of mineralization at South Limb and 15.50 metres of mineralization at N2 Limb.

● Drill hole SNUG-25-190, currently in progress, is stepping out to test the strike extent of mineralization.

● Total metres not included in the MRE is 37,113 metres in 85 holes.

Morgan Lekstrom, CEO of the Company, commented: “The results from drill holes 184 and 185 continue to demonstrate the impressive step-out success and the broader scale of mineralization beyond the boundaries of the current resource. Drilling has further extended the deposit intercepting mineralization roughly 315 metres down-plunge, well past its modeled limits. Given our existing resource grades of over 3% CuEq, this result further validates the potential of this system. Our application of BHEM, combined with a deep technical understanding of the deposit, is allowing us to target these deeper zones with incredible precision. The system remains open, and the BHEM results combined with these first assays reinforces our confidence that this mineralized corridor continues at depth.”

Assay results have been received and reported below in Table 1 and drill hole collar details are provided in Table 2. Assays are pending for all other drill holes described herein.

The various mineralized zones have been historically mined and subsequently named N2 Limb, N3 Limb and South Limb to demarcate their location on the folded mineralized horizon. Additional drilling is needed to properly determine true width of mineralization on each limb and define the folded mineralization.

¹Length refers to drillhole length and not true width. True widths are unknown.

²Co is not included in the MRE as cobalt analyses are not consistently available throughout the deposit.

³CuEq was calculated using the formula CuEq=Cu+2.06*Ni assuming long-term prices of US$10.50/lb Ni and US$4.75/lb Cu nickel and copper recoveries of 72.0% and 92.4% respectively, derived from metallurgical studies which consider a conceptual bulk concentrate scenario.

Next Steps

Completed drill hole SNUG-25-189 was drilled between SNUG-25-096-W1 and SNUG-25-184 and intersected 5.20 metres of mineralization at South Limb and 15.50 metres of mineralization at N2 Limb.

Follow-up drilling is underway, with drill hole SNUG-25-190 targeting the strike extent at a distance of 115 metres from SNUG-25-184 to further evaluate the continuity and scale of both the South Limb and N2 mineralized systems.

Qualified Person

All scientific and technical information in this news release has been reviewed and approved by Sharon Taylor, VP Exploration of the Company, MSc, P.Geo, and a “qualified person” for the purposes of National Instrument 43-101.

Quality Control

The underground drilling program is being carried out through an agreement with Forage Fusion Drilling Ltd. of Hawkesbury, Ontario, Canada, who have provided three Zinex U-5 drills for purchase and training of local operators. Drill core samples are BQTK (40.7 mm diameter). All samples are ½ core cut by a diamond saw on site. Half of the core is retained for reference purposes. Samples are generally 1.0 to 1.5 metre intervals or less at the discretion of the site geologists. Sample preparation and lab analysis was completed at ALS Chemex in Johannesburg, South Africa. Commercially prepared blank samples and certified Cu/Ni sulphide analytical control standards with a range of grades are inserted in every batch of 20 samples or a minimum of one set per sample batch. Analyses for Ni, Cu and Co are completed using a peroxide fusion preparation and ICP-AES finish (ME-ICP81).

Holes are numbered as follows: SNUG (Selebi North Underground) + year + hole number starting at 013.
