NVRO Metals Announces Independent NI 43-101 Mineral Resource Estimate of 77.6 Million-Tonne Polymetallic Resource at the NVRO Metals Hub

Executive Summary

• NVRO Metals Limited announced a draft independent mineral resource estimate (MRE) for its NVRO Metals Hub in Australia’s Northern Territory, following the completion of its acquisition of Northern Territory Resources Pty Ltd.
• The combined resource totals approximately 77.6 million tonnes grading 1.69% copper-equivalent (CuEq), with 94.2% classified as Measured or Indicated, providing independent validation of the asset's scale, quality, and strategic significance.
• The estimate establishes a foundation for near-term oxide production (copper, cobalt, nickel) and long-term sulfide development, consolidating the Browns, Browns East, Area 55, and Mount Finch deposits into a centralized critical minerals processing platform.

Key Details

• Combined Mineral Resource: 77.57 Mt grading 1.69% CuEq (0.46% Cu, 2.35% Pb, 0.40% Zn, 0.09% Co, 0.08% Ni, 8.40 g/t Ag)
• Classification Breakdown: Measured 40.48 Mt (52.2%), Indicated 32.58 Mt (42.0%), Inferred 4.51 Mt (5.8%)
• Oxide Mineral Resource: 15.90 Mt grading 1.01% CuEq (0.49% Cu, 0.52% Pb, 0.52% Zn, 0.10% Co, 0.11% Ni)
• Sulfide Mineral Resource: 61.67 Mt grading 1.86% CuEq (0.45% Cu, 2.82% Pb, 0.48% Zn, 0.09% Co, 0.07% Ni, 10.57 g/t Ag)
• Implied In-Situ Metal Resources: Copper 356,000 tonnes, Zinc 310,000 tonnes, Nickel 62,100 tonnes, Lead 1,823,000 tonnes, Cobalt 69,800 tonnes, Silver 20,951,000 oz
• Data Basis: 360,000 drill meters, 5,761 drill holes, 1.5 million assays, and $60 million in historical database collection spend
• Cut-Off Grades: Oxide resource modeled at 0.5% CuEq; Sulfide resource modeled at 0.7% CuEq
• Metallurgical Recovery Assumptions: Oxide (Cu 72%, Co 58%, Ni 21%); Sulfide (Cu 87%, Co 77%, Ni 77%, Pb 90%, Zn 86%, Ag 86%)
• CuEq Calculation Formulas:
• Oxide: Cu% + (Co% × 4.25) + (Ni% × 0.51)
• Sulfide: Cu% + (Pb% × 0.2) + (Zn% × 0.25) + (Co% × 4.67) + (Ni% × 1.53) + (Ag g/t × 0.02)
• Pricing Basis: CIBC long-term consensus prices as of June 1, 2026
• Qualified Person: Troy Lowien, BASc. (Hons.), MAIG, Principal Geologist of Measured Group
• Next Steps: Final technical report expected on or before July 10, 2026, with full filing on SEDAR+ within 45 days per NI 43-101 requirements.
• Strategic Outlook: Supports near-term oxide restart for operating cash flow, followed by sulfide development and long-term deployment of the NVRO Process™ for copper, cobalt, silver, lead, nickel, and zinc production.
