Increased Ore Reserve and Improved Economics

(AIM:HALO) Halo Minerals PLC announced an updated Competent Person’s Report (CPR) for its Playa Verde copper tailings project in Chile, increasing the Ore Reserve by 5.4% to 33.94 Mt at 0.25% Cu, containing 83,626 tonnes of in-situ fine copper. The Ore Reserve base case supports an after-tax NPV10 of US$174.3 million and an after-tax IRR of 45.6%, with project-level average annual free cashflows of US$56 million. Total Mineral Resources are 53.44 Mt at 0.24% Cu, inclusive of Ore Reserves, containing 127,911 tonnes of in-situ fine copper. A full-resource management case, using the entire 53.44 Mt onshore Mineral Resource, produces an after-tax NPV10 of US$267.5 million and an after-tax IRR of 48%. Identified CAPEX and reagent-cost optimisation increases the after-tax NPV10 to US$190.6 million for the Ore Reserve case and US$295.5 million for the full-resource management case. EMI-Ingenieros y Consultores S.A. (EMI) prepared the CPR, incorporating the 2026 basic engineering update and Class 3 capital and operating cost estimates by BIOS Mining & Infrastructure. The Ore Reserve base case uses a copper price of US$6.20/lb, gold price of US$3,700/oz, initial CAPEX of US$92.8 million, and acid at US$200/t. The production programme assumes a consolidated extraction and processing rate of approximately 5.0 Mtpa and an initial operating period of seven years, with approximately 34.8 Mt sent to the plant, including 0.86 Mt of Inferred Resource (not included in the declared Ore Reserve or economic case). Base-case operating costs are estimated at approximately US$2.20/lb of copper produced and marketed. BIOS MI identified potential to reduce initial CAPEX by US$6 to 10 million and to lower acid costs to US$150/t through a long-term supply contract. The September 2026 recategorisation incorporated an additional 1.74 Mt of Measured and Indicated Resources into the extraction plan, increasing Ore Reserves by 5.4%. EMI considers preliminary potential to increase Ore Reserves by approximately 25% to 30% in the short term, subject to further technical work. Potential Ore Reserves could increase to approximately 42.4 Mt to 44.1 Mt. Further NPV upside of approximately US$4.4 million may be available through optimisation of the dredging starting point and extraction sequence. The process route combines acid leaching, solvent extraction, electrowinning, and flotation, with an estimated overall copper recovery of approximately 72%. The CPR was compiled under the supervision of Mr Orlando Rojas Vercelotti, Civil Mining Engineer and Competent Person as defined in the JORC Code (2012). Andrew Dennan is Chief Executive Officer and Frank Jackson is Chief Financial Officer of Halo Minerals PLC.

Halo Minerals Plc — Interim Results and Operational Update

(AIM: HALO) Halo Minerals PLC announced its Interim Results for the six months ended 30 June 2026, highlighting the successful AIM admission and completion of a £4 million IPO fundraise. The company continued advancement of its flagship Playa Verde copper and gold tailings reprocessing project in Chile, which is underpinned by a JORC (2012) Mineral Resource Estimate of 53Mt at 0.24% Cu containing approximately 126,000 tonnes of copper, including Ore Reserves of 32.2 Mt at 0.25% Cu. An independent competent persons report in February 2026 illustrated the Project to have an NPV10 of approximately US$154 million and an IRR of approximately 51%, based on Ore Reserves only and using copper and gold price assumptions of US$5.30/lb copper and US$4,300/oz gold. The company reported a total loss before tax of £2.9 million for the period, comprising £2.4 million in admin costs, £0.4 million in finance costs, and £0.1 million in foreign exchange losses, with £0.5 million of admin expenses attributed to share based payment expenses and a further £0.5 million in non-cash admin costs from share settlements. Cash admin costs were reconciled to approximately £1.4 million, including approximately £0.5 million associated directly with the IPO and readmission. The company is now debt free and has a clean balance sheet, with funding expected to last through to H2 2027. The company engaged BIOS Mining & Infrastructure for ongoing optimisation work on the Definitive Feasibility Study (DFS), and is progressing environmental and permitting workstreams, including the Beach Mining Permit and Maritime Concession application. The First Environmental Tribunal of Chile rejected in its entirety the judicial challenge against the Chilean Committee of Ministers' environmental approval of Playa Verde, upholding the Project's favourable environmental qualification. The company is evaluating additional tailings reprocessing opportunities and offshore resource growth within the Playa Verde licence area, with estimates of approximately 100 million tonnes of copper-bearing tailings offshore and a potential 200% resource upside referenced in the 2026 CPR.

Judgment Rejects Challenge to Playa Verde

(AIM:HALO) Halo Minerals PLC announced that the First Environmental Tribunal of Chile has rejected in its entirety the judicial challenge filed on 28 November 2025 against the Chilean Committee of Ministers' environmental approval of the Company's Playa Verde project, which was received in written resolution on 15 October 2025. The Tribunal upheld the October 2025 decision granting a favourable environmental qualification (RCA) for Playa Verde (Resolution Ex. No. 202599101932 of 15 October 2025). Playa Verde has a JORC compliant resource of 53.4 Mt @ 0.24% Cu, including reserves of 32.2 Mt @ 0.25% Cu, and is updating its DFS for dredging and retreatment initially targeting the reserves of ore located on the beach followed by up to a further 21 Mt of ore in the western berm and shoreline area. The project has an NPV10 of US$ 154.1 million and an IRR of 50.9% after tax from a 7 year life of mine, with estimated operating costs of $2.19 per pound of copper produced. The Tribunal upheld the Company's commitment to reduce arsenic concentrations in the return sands to a maximum of 47 mg/kg. The company continues to target a Final Investment Decision (FID) in respect of Playa Verde by end of 2026 and is engaging with potential industrial capital partners for project funding. The project is well placed with significant upside in securing the rights to process up to a further 100 Mt of potential offshore resource.

Filing of Maritime Concession Application

Halo Minerals PLC (AIM:HALO) has commenced the procedure to file a formal maritime concession application with the Chilean maritime authority for an offshore extension at its Playa Verde Project in Chañaral, Atacama Region. The concession, if granted, would cover shoreline and offshore areas adjacent to the company's flagship project, potentially providing access to approximately 100 million tonnes of copper-bearing tailings in addition to its existing 53 million tonne JORC-compliant resource and 32.2 million tonnes of ore reserves onshore. The project has a post-tax NPV10 of US$154.1 million and IRR of 50.9% at US$5.30/lb Cu and US$4,300/oz Au, with operating costs estimated at $2.19 per pound of copper produced.
