Drill Results Resource Estimates

NexMetals Intersects 32.60 Metres of

Mineralization at Selebi North Bridging Major

Step-Out Holes & Strengthening MRE

Expansion

Vancouver, British Columbia--(Newsfile Corp. - October 1, 2025) -

NexMetals Mining Corp. (TSXV:

NEXM) (NASDAQ: NEXM)

(the "

Company

") is pleased to announce that it has successfully

intersected significant massive sulphide mineralization within a newly completed drill hole at Selebi

North Underground ("

SNUG

"), confirming the down-plunge continuity of mineralization. This intersection

represents the thickest interval of mineralization drilled by NEXM in its 2025 resource expansion

program and will be included in the future updated Mineral Resource Estimate ("

MRE

"). Assays are

pending for SNUG-25-194 and an additional 2 holes.

Why this matters:

SNUG-25-194 intersected

32.60 metres of continuous mineralization at Selebi North South

Limb, including an aggregate total of 19.90 metres of massive sulphide across five sub-

intervals.

True thickness is estimated at 60 - 65%

, which is consistent with geological interpretations of

the South Limb.

Drill hole SNUG-25-194 was designed to bridge mineralization between two widely

spaced resource expansion drill holes SNUG-25-184, located 183 metres down-plunge

from the current MRE, and SNUG-25-186, a further 130 metre step-out

(see

news releases

dated June 30 and August 13, 2025

).

The demonstrated continuity between these two major step-outs and results from additional strike

step-outs from the resource expansion program can be

incorporated into a future MRE update,

supporting a potential expansion of the resource envelope.

Next Steps:

Borehole electromagnetic ("BHEM") surveys

are planned to characterize the conductive

trends associated with the newly intersected massive sulphides to confirm continuity and outline

strike extent.

Initial interpretations indicate that the new data will

contribute to resource expansion in an

updated MRE

.

Ongoing drilling

to

further demonstrate the scale, continuity, and expansion potential

of

the Selebi North deposit.

Morgan Lekstrom, CEO of the Company

, commented: "This is a critical confirmation point for Selebi

North. By bridging two major step-out holes and intersecting significant massive sulphide intervals, we

have validated the down-plunge continuity and further strengthened our geological model. Once assays

are received, these results will be incorporated into the updated MRE, reinforcing Selebi North's scale,

quality, and expansion potential."

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 and Subpart 1300 of Regulation S-K.

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.
