Drill Results

NexMetals Drills 210 Metres of 1.06% CuEq

Highlighting Continuous Mineralization and Expansion at

Selkirk

Vancouver, British Columbia--(Newsfile Corp. - September 23, 2025) -

NexMetals Mining Corp.

(TSXV: NEXM) (NASDAQ: NEXM)

(the "

Company

") announces assay results from two additional

holes from the 12 hole metallurgical drilling program completed at the past-producing Copper, Nickel,

Cobalt and Platinum Group Elements ("

Cu-Ni-Co-PGE

") Selkirk Mine in Botswana.

Why This Matters: Scale, Grade, Growth

SMET-25-004: wide interval of continuous mineralization

210.00 metres of 1.06% CuEq

(0.40% Cu, 0.36% Ni, 0.59 ppm Pd, 0.14 ppm Pt)

incl. 74.00 metres of 1.28% CuEq (0.45% Cu, 0.46% Ni, 0.73 ppm Pd, 0.17 ppm Pt)

Mineralization outside the Mineral Resource Estimate ("MRE") and within the current

conceptual pit shell, demonstrating the potential for expansion of the deposit toward the

surface.

SMET-25-001: starting at 13.00 metres from surface

45.00 metres of 0.69% CuEq

(0.23% Cu, 0.23% Ni, 0.46 ppm Pd, 0.10 ppm Pt)

Large widths of near-surface mineralization support open-pit development potential with a low strip

ratio (see technical report).

Current cut-off of US$25.00 per tonne net smelter return defined in the MRE translates to 0.46%

CuEq. Any material above this cut-off grade could be potentially mined.

These results bring the total number of metallurgical drill holes announced from the 2025 program

to four (

see

news release dated September 18, 2025

), with assays to be released on an

ongoing basis.

Morgan Lekstrom, CEO of the Company, commented:

"The results today, combined with last

week's news of drill hole 003, highlight multiple intercepts over 200 metres of high-grade mineralization,

once again exceeding our expectations at Selkirk

.

These results position Selkirk as a standout asset,

reinforcing the substantial scale of the deposit. Exceptionally notable are drill holes 003 and 004, as they

show very similar grades despite being more than 125 metres apart. This further emphasizes both the

size, consistency, and presence of broad intervals of higher grades within this deposit. Upcoming

catalysts include resource expansion, metallurgical results and optimization, rapidly unlocking the full

value and long-term potential of the Selkirk mine."

Technical Report

The MRE on the Selkirk Mine is supported by the Technical Report entitled "NI 43-101 Technical Report

Selkirk Nickel Project, North East District, Republic of Botswana", dated January 8, 2025 (with an

effective date of November 1, 2024). Reference should be made to the full text of the Technical Report

for the assumptions, qualifications and limitations set forth therein, which was prepared in accordance

with NI 43-101 and Subpart 1300 of Regulation S-K and is available on SEDAR+ (

www.sedarplus.ca

)

and EDGAR (

www.sec.gov

), in each case, under NEXM's issuer profile.

Quality Control

The Selkirk metallurgical drill program was completed by Discovery Drilling using a Boyles 56 machine.

Drill core samples are HQ (63.5 mm diameter) that were sawn in half with one half sawn in half again to

produce quartered core. Selected portions of the remaining core were sent to Blue Coast Research for

metallurgical flotation studies with the reminder retained for reference purposes. The quartered core

samples submitted to the lab were generally 1 metre in length. 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). Analyses for Pt, Pd, and Au are by fire

assay (30 grams nominal sample weight) with an ICP-AES finish (PGM-ICP23).
