 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).  
 Next Steps: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.
 
 
 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.
