Drill Results

NexMetals Drills 13.50 Metres of 3.68% CuEq

Expanding Mineralization Significantly Below

Selebi North Resource Footprint

Vancouver, British Columbia--(Newsfile Corp. - 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.

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

CuEq 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.
