NexMetals Reports Final Drill Results from Its
2025 Selebi North Underground Program;
Confirms High-Grade Continuity with 18.80
Metres of 4.69% CuEq (2.10% Cu and 1.26% Ni)
Vancouver, British Columbia--(Newsfile Corp. - April 1, 2026) -
NexMetals Mining Corp. (TSXV:
NEXM) (NASDAQ: NEXM)
(the "
Company
" or "
NEXM
") is pleased to report assay results from the
final three drill holes of its completed 2025 Selebi North Underground ("
SNUG
") deposit drilling program
(see Figures 1 and 2). The program, which comprised of 9,656 metres in 11 completed holes and 6
abandoned holes, was designed to support resource expansion specifically, the down plunge and strike
continuity of mineralization in the South Limb and down plunge extent of N3 (see Figure 1). The program
has been successfully completed, with results confirming the continuity of high-grade mineralization
along key target zones.
Highlights
SNUG-25-197: 18.80 metres of 4.69% CuEq (2.10% Cu, 1.26% Ni)
including: 6.45 metres of 5.67% CuEq (2.25% Cu, 1.66% Ni)
Drilling continues to reinforce confidence in the scale and continuity of the SNUG deposit, with
recent step-out results complementing previously reported thick, continuous high-grade intervals,
supporting the potential to rapidly add tonnage to the updated Mineral Resource Estimate
("
MRE
").
The 2025 SNUG drilling program extended the footprint of the South Limb mineralization
approximately 315 metres down-plunge beyond the 2024 MRE, expanding South Limb by roughly
35% (
see news release dated August 13, 2025
).
Deepest holes indicate improving copper grades down-plunge.
Next Steps
The surface drilling program is continuing at the Selebi Main Deposit, with four rigs targeting the
emerging Flexure Zone, where recent results indicate thick intervals of massive sulphide
mineralization.
Incorporation of 2023-2025 Selebi North and 2026 Selebi Main drill holes into an updated MRE
that incorporates the updated metallurgical test work results.
Sean Whiteford, CEO of the Company, commented:
"The 2025 Selebi North underground program
has been highly successful, with these results demonstrating the continuity and scale that remain at the
deposit, particularly along the down-plunge extension of the South Limb. Drilling is also confirming
increasing copper grades at depth, with high-grade intervals consistently encountered within broader
mineralized zones. At the same time, ongoing drilling at Selebi Main is consistently intersecting thick
intervals of mineralization, reinforcing that the system remains open and continues to grow. Together,
these results provide increased confidence in the overall scale of the Selebi system and will be key
inputs into our updated MRE and PEA."

Assay results for the three final holes are reported below in Table 1 and drill hole collar details are
provided in Table 2. SNUG-25-197 and SNUG-25-199 were step-out holes to test South Limb
mineralization continuity down dip and along strike, and this drilling was required for the updated MRE.
Both holes intersected South Limb mineralization outside the thick zone of mineralization in the fold
nose. SNUG-25-200 targeted down plunge extent of N3 and intersected narrow intervals of sulphides,
confirming the fold structure continues to depth beyond the extent of the 2024 MRE.
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.

Length refers to drillhole length and not true width. True widths are estimated where density of drilling is sufficient for
an estimation. Some true widths cannot be estimated due to insufficient drill density in the folded mineralized horizon.
2
Co is not included in the 2024 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, and nickel and copper
recoveries of 72.0% and 92.4%, respectively, derived from metallurgical studies which consider a conceptual bulk concentrate scenario.

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. Sharon Taylor has verified the data
disclosed in this news release, including the sampling, analytical and test data underlying the disclosure,
through multiple visits to drill sites and sample preparation facilities, assessment and oversight of
sample preparation protocols, and review of the QA/QC procedures applied to analytical results

the results.
Quality Control
The drill program was completed using a company owned Zinex U5 drill. 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.
