Nexmetals Mining Corp Announces Updated Mineral Resource Estimate for Selkirk Project
NexMetals Mining Corp. announced an updated Mineral Resource Estimate for its Selkirk Project in Botswana. The 2026 MRE, completed by The MSA Group in Johannesburg, South Africa, increases the Project's contained copper equivalent metal inventory by approximately 63% and reflects a significant conversion of Mineral Resources from the Inferred to Indicated category following a successful re-assaying and twin drilling campaign. The 2026 MRE represents an important technical milestone for the Selkirk Project, enhancing resource confidence and reducing development risk. Approximately 1.1 billion pounds of copper equivalent Mineral Resources in the Indicated category with 78.2 Mt grading 0.66% copper equivalent (0.21% nickel, 0.23% copper, 0.012% cobalt, 0.10 g/t platinum, 0.42 g/t palladium, 0.05 g/t gold and 0.72 g/t silver). Approximately 200 million pounds of copper equivalent Mineral Resources in the Inferred category with 15.1 Mt grading 0.60% copper equivalent (0.18% nickel, 0.21% copper, 0.010% cobalt, 0.09 g/t platinum, 0.40 g/t palladium, 0.05 g/t gold and 0.77 g/t silver). Key drivers of the increase from the 2024 Mineral Resource Estimate include significant improvement in metallurgical recoveries resulting in higher expected payabilities, inclusion of cobalt, silver and gold as payable metals, none of which were assigned value in the 2024 MRE due to limited assaying, and expanded platinum, palladium, silver, cobalt and gold datasets from the historical core resampling program, supporting an expanded mineralized envelope and larger conceptual pit shell on a Net Smelter Return basis. Metal price changes had a minimal net impact relative to the 2024 MRE, reflecting Selkirk's diversified polymetallic metal mix, which provides exposure to multiple payable metals while reducing single-commodity price risk. The 2026 MRE incorporates previously reported metallurgical results that confirm the ability to produce separate, clean copper and nickel concentrates that meet commercial smelter specifications, further de-risking the project. Strip ratio reduced to 1.02:1 from 1.65:1, among the lowest strip ratios for copper development projects globally, resulting from the inclusion of additional tonnage sitting above and adjacent to the 2024 MRE. The 2026 MRE Summary shows Indicated resources of 78.2 million tonnes with NSR USD 56, grade 0.66% copper equivalent, 0.21% nickel, 0.23% copper, 0.012% cobalt, 0.10 g/t platinum, 0.42 g/t palladium, 0.05 g/t gold, 0.72 g/t silver. Inferred resources are 15.1 million tonnes with NSR USD 51, grade 0.60% copper equivalent, 0.18% nickel, 0.21% copper, 0.010% cobalt, 0.09 g/t platinum, 0.40 g/t palladium, 0.05 g/t gold, 0.77 g/t silver. Total contained metal in Indicated category is 1,138 million pounds copper equivalent, 163 thousand tonnes nickel, 181 thousand tonnes copper, 9.2 thousand tonnes cobalt, 245 thousand ounces platinum, 1,066 thousand ounces palladium, 120 thousand ounces gold, 1,818 thousand ounces silver. Inferred category contains 200 million pounds copper equivalent, 27 thousand tonnes nickel, 32 thousand tonnes copper, 1.6 thousand tonnes cobalt, 45 thousand ounces platinum, 193 thousand ounces palladium, 25 thousand ounces gold, 372 thousand ounces silver. Copper equivalent is calculated using the formula CuEq % = 91.4Cu(%) + Ni(%)(85.1/91.4) + Co(%)(93.8/91.4) + Pt(g/t)(22.4/91.4) + Pd(g/t)(33.1/91.4) + Au(g/t)(68.5/91.4) + Ag(g/t)*(0.8/91.4). Mineral Resources, which are not Mineral Reserves, have no demonstrated economic viability. The estimate of Mineral Resources may be materially affected by geology, environment, permitting, legal title, taxation, socio-political, marketing, or other relevant issues. The 2026 MRE has been prepared in accordance with the CIM Definition Standards (2014) and CIM Best Practice Guidelines (2019) with an effective date of June 22, 2026. Mineral Resources are reported at a cut-off value of USD 25/t NSR defined as received value of final metal recovered minus off-site costs. Mineral Resources are estimated using long-term prices of USD 9.10/lb nickel, USD 5.10/lb copper, USD 20.00/lb cobalt, USD 1,800/oz platinum, USD 1,550/oz palladium, USD 3,600/oz gold and USD 52.00/oz silver. The same metal prices were used in copper equivalent and NSR calculations. Mineral Resources are estimated using nickel, copper, cobalt, platinum, palladium, gold and silver recoveries of 54%, 88%, 53%, 56%, 78%, 72% and 61%, respectively, derived from metallurgical studies which consider a two-concentrate scenario. Payabilities and off-site treatment and refining costs were derived from an independent marketing study commissioned by NexMetals. The copper equivalent value was calculated based on relative recovered value received for each metal excluding costs. Bulk density has been estimated in the block model based on an extensive data set of measurements taken from drillhole cores. Mineral Resources are reported within an optimized pit shell using NSR values, mining cost of USD 3/tonne (additional USD 0.008 per metre depth from pit rim), concentrate costs of USD 20/tonne, G&A of USD 1.35 per tonne, 45° pit slope to base of partially weathered and 60° in fresh rock. The previous Selkirk Mineral Resource Estimate comprised 789 million pounds of copper equivalent in the Inferred category with 44.2 Mt grading 0.81% copper equivalent (0.30% copper, 0.24% nickel, 0.55 g/t palladium and 0.12 g/t platinum), entirely within the Inferred category. The updated model demonstrates a substantial increase in resource confidence through the conversion of a significant portion of the mineralization to the Indicated category. The model also illustrates a materially expanded conceptual open-pit shell relative to the 2024 MRE, reflecting increased contained metal.
