NexMetals (NASDAQ: NEXM) posts strong Selkirk CuEq intercepts and hires NH IR

Rhea-AI Filing Summary

NexMetals Mining Corp. reported new drilling and resampling results from its Selkirk copper-nickel-cobalt-PGE mine in Botswana and announced a new investor relations engagement. A key interval from hole DSLK211 returned 180.8 metres grading 1.31% CuEq, including 123 metres at 1.59% CuEq, within a conceptual open-pit shell.

The company also highlighted high-grade footwall mineralization, including 6.90 metres grading 7.92% CuEq in hole DSLK077, which is being considered a potential new exploration target. All assay results from the 34-hole resampling program are now available and will be incorporated, along with new metallurgical data, into an updated Mineral Resource Estimate expected in Q2 2026.

NexMetals engaged NH IR Advisory Corp., a Toronto-based investor relations firm, for a twelve-month term at a monthly fee of C$12,000. Principal Nisha Hasan is slated to receive incentive stock options valued at C$72,000, exercisable for five years and vesting over twelve months, subject to TSX Venture Exchange approval.

Insights

Mining equity analyst

New Selkirk drill results strengthen resource update story while IR engagement targets broader investor outreach.

NexMetals delivered multiple long Cu-Ni-Co-PGE intervals at Selkirk, notably 180.8 metres at 1.31% CuEq in DSLK211 and 6.90 metres at 7.92% CuEq in DSLK077 footwall mineralization. Management plans to roll these data, plus metallurgical results, into an updated Mineral Resource Estimate in Q2 2026.

The company emphasizes that resampling historic core for PGEs should better capture their expected contribution to net smelter return, especially within the conceptual pit shell. Actual impact on resource size and strip ratio will depend on how these assays re-shape the block model in the forthcoming estimate.

On the corporate side, engaging NH IR Advisory Corp. for C$12,000 per month and issuing options valued at C$72,000 aligns with a strategy to increase capital-markets visibility. Subsequent disclosures of the updated MRE in Q2 2026 will be important for understanding how materially these results change Selkirk’s project profile.

Exhibit 99.1

NEXMETALS REPORTS 180.8 METRES OF 1.31% CuEq FROM SELKIRK RESAMPLING PROGRAM AND ENGAGES IR ADVISORY FIRM

Vancouver, British Columbia, March 19, 2026 – NexMetals Mining Corp. (TSXV: NEXM) (NASDAQ: NEXM ) (the “Company”) announces assay results from resource gap hole DSLK-25-012 and from the remaining 28 holes of its 34-hole resampling program at the past-producing Copper Nickel Cobalt Platinum Group Elements (“Cu-Ni-Co-PGE”) Selkirk Mine in Botswana.

Assay Highlights:

● DSLK-25-012: 101.00 metres of 0.85% CuEq

(0.28% Cu, 0.29% Ni, 0.01% Co, 0.56ppm Pd, 0.12ppm Pt and 0.05ppm Au)

● DSLK076: 94.20 metres of 0.96% CuEq

(0.34% Cu, 0.30% Ni, 0.02% Co, 0.63ppm Pd, 0.13ppm Pt and 0.06ppm Au)

● DSLK134: 86.00 metres of 1.06% CuEq

(0.34% Cu, 0.45% Ni, 0.02% Co, 0.55ppm Pd, 0.12ppm Pt and 0.05ppm Au)

● DSLK211: 180.80 metres of 1.31% CuEq

(0.52% Cu, 0.39% Ni, 0.02% Co, 0.79ppm Pd, 0.17ppm Pt and 0.11ppm Au)

● DSLK258: 68.00 metres of 0.91% CuEq

(0.28% Cu, 0.32% Ni, 0.02% Co, 0.61ppm Pd, 0.13ppm Pt and 0.05ppm Au)

Footwall Mineralization

● DSLK077: 6.90 metres of 7.92% CuEq

(5.33% Cu, 1.31% Ni, 0.08% Co, 2.55ppm Pd, 0.56ppm Pt and 0.45ppm Au)

● DSLK134: 5.90 metres of 2.79% CuEq

(0.63% Cu, 1.76% Ni, 0.07% Co, 0.73ppm Pd, 0.12ppm Pt and 0.04ppm Au)

Why This Matters

	●	Wide intervals of Cu-Ni-Co-PGE mineralization intersected within the conceptual pit shell.
	●	High grade footwall mineralization is an exploration target.
	●	DSLK-25-012 was drilled to infill a gap in the resource and achieve a minimum drill spacing density of 60m across the deposit.
	●	All assay results have been received for the 34-hole resampling program and are ready to be incorporated into an updated Mineral Resource Estimate (“MRE”). Historic drillholes were inconsistently assayed for PGEs, which are expected to contribute approximately one-third of the deposit’s net smelter return value. The resampling program captures intervals that were not previously analyzed for PGEs, providing additional data for incorporation into the model.
	●	Incorporating PGE values—particularly in mineralization located beyond the current limits of the 2024 Mineral Resource Estimate (the “2024 MRE”) and within the conceptual pit shell—has the potential to expand the mineral resource and reduce the strip ratio.

Key Takeaway

● Wide intervals of Cu-Ni-Co-PGE mineralization exceeding the current resource cut off grade of 0.46% CuEq were mapped outside the 2024 MRE and within the conceptual pit shell. This data will be incorporated into the updated MRE expected in Q2 2026.

Sean Whiteford, CEO of the Company, commented: “The Selkirk drilling and resampling program continues to deliver wide intervals of Cu, Ni and PGE mineralization. We will be incorporating these assay results, combined with new metallurgical results, into an updated MRE anticipated in Q2 2026. Additionally, the exceptional results from DSLK077 (6.90m at 7.92% CuEq) indicate a potential new footwall zone for further follow up.”

The assay results of the resource gap hole and the 28 resampled holes referenced in this press release are summarized in Table 1 and drillhole information is provided in Table 2.

Quality Control

Historic drill core samples are NQ (47.6 mm diameter) that were previously sawn in half. All current samples are ¼ core cut by a diamond saw on site. The remaining ¼ core is retained for reference purposes. Samples are generally 0.30 metre or less and correspond to the historic sample intervals. 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).

FAQ

What did NexMetals Mining Corp. (NEXM) report from the Selkirk resampling program?

NexMetals reported wide copper-nickel-PGE mineralized intervals from Selkirk. Key results include 180.8 metres grading 1.31% CuEq in hole DSLK211 and high-grade footwall zones. All 34-hole resampling assays will support an updated Mineral Resource Estimate for the Botswana project.

Why are the new Selkirk drill and resampling results important for NEXM investors?

The new Selkirk assays will feed directly into NexMetals’ next resource update. Resampling historic core for PGEs is intended to better capture their contribution to net smelter return and may influence mineral resource size and pit design in the planned Q2 2026 estimate.

What are the standout high-grade intervals NexMetals (NEXM) highlighted at Selkirk?

NexMetals highlighted both long and very high-grade zones. DSLK211 returned 180.8 metres at 1.31% CuEq within a conceptual pit shell, while DSLK077 footwall mineralization delivered 6.90 metres at 7.92% CuEq, considered a potential new exploration target for follow-up work.

When does NexMetals Mining Corp. expect the updated Selkirk Mineral Resource Estimate?

NexMetals anticipates releasing an updated Mineral Resource Estimate in Q2 2026. This update is expected to incorporate the full 34-hole resampling dataset, newly reported metallurgical results, and expanded PGE information tied to the 2024 Mineral Resource framework.

What investor relations agreement did NexMetals (NEXM) sign with NH IR Advisory Corp.?

NexMetals engaged NH IR Advisory Corp. for investor relations services. The twelve-month agreement includes a monthly fee of C$12,000 and incentive stock options valued at C$72,000 for principal Nisha Hasan, vesting over twelve months and exercisable for five years, subject to TSXV approval.

How does NexMetals Mining Corp. (NEXM) calculate CuEq grades at Selkirk?

CuEq grades are calculated using copper, nickel and PGE contributions. The formula CuEq% = Cu% + Ni%*(55.605/53.913) + Pd g/t*(22.948/53.913) + Pt g/t*(14.891/53.913) uses metal prices and recoveries from the 2025 Selkirk NI 43-101 Technical Report.
