SURGE BATTERY METALS ENGAGES KEMETCO FOR ADVANCED PREFEASIBILITY METALLURGICAL TESTING AT THE NEVADA NORTH LITHIUM PROJECT

Nevada North Lithium LLC (NNL), the joint venture formed by Surge Battery Metals Inc. and Evolution Mining Ltd., has commenced an advanced metallurgical optimization program with Kemetco Research Inc. to support the continuing prefeasibility study (PFS) for the company's flagship, high-grade Nevada North lithium project (NNLP) located in Elko county, Nevada.

This comprehensive testing program utilizes a master composite sample -- representing the first 10 years of mine life designed in direct collaboration with Fluor Corp., the lead engineering firm for the PFS. The primary objective is to validate and optimize the specific process design criteria (PDC) and heat and mass balance (HMB) models currently being engineered by Fluor.

Strategic continuity and engineering alignment

Kemetco's familiarity with the NNLP mineralization and hydrometallurgy flow sheets qualify them as the premier choice for this phase of derisking. Having successfully executed the foundational metallurgical testing for the company's preliminary economic assessment dated May 19, 2025 (PEA), Kemetco provides necessary continuity. Their historical data and hands-on experience with the NNLP claystone ensure that this optimization phase will be executed efficiently, bridging the gap between bench-scale data and Fluor's commercial-scale plant design.

Key technical highlights of the PFS test program:

• Flowsheet optimization: comprehensive testing across the entire proposed flowsheet, including sulphuric acid leaching, neutralization and counter-current decantation (CCD);
• Impurity removal and ZLD integration: advanced testing of the impurity removal circuits to validate reagent consumption (such as lime and soda ash) and the simulation of the zero liquid discharge (ZLD) circuit, a critical component of Surge's water conservation strategy;
• Product validation: precipitation and crystallization testing to confirm the efficient production of high-purity lithium carbonate;
• Byproduct evaluation (cesium and rubidium): the program will strictly monitor the deportment of cesium (Cs) and rubidium (Rb) throughout the leaching and purification phases to assess the economic viability of recovering these high-value specialty metals as project byproducts.

Greg Reimer, president and chief executive officer and director of Surge, commented: "We are very pleased to be working with Kemetco again. By pairing their intimate understanding of our Nevada North deposit with Fluor's commercial engineering capabilities, we are combining the necessary expertise to complete the testwork and lock in our optimized flowsheet. This will support our fully funded joint ventured prefeasibility study."

About Surge Battery Metals Inc.

Surge Battery Metals, a Canadian-based mineral exploration company, is at the forefront of securing the supply of domestic lithium through its active engagement in the Nevada North lithium project. The project focuses on development of high-grade lithium energy metals in Nevada, U.S., a crucial element for powering battery electric storage and electric vehicles. With a primary listing on the TSX Venture Exchange in Canada and a listing on the OTCQX Market in the U.S., Surge Battery Metals is strategically positioned as a key player in advancing lithium exploration.

About Nevada North Lithium LLC

Nevada North Lithium LLC, jointly owned by Surge Battery Metals (72.5 per cent) and Evolution Mining (27.5 per cent), owns the Nevada North lithium project southeast of Jackpot, Nev., about 73 kilometres north-northeast of Wells, Elko county. The first three rounds of drilling at the project identified a strongly mineralized zone of lithium-bearing clays occupying a strike length of more than 4,300 metres and a known width of greater than 1,500 metres. Highly anomalous soil values and geophysical surveys suggest there is potential for the clay horizons to be much greater in extent. As disclosed in the company's preliminary economic assessment dated May 19, 2025 (PEA), completed jointly by M3 Engineering & Technology Corp. and Independent Mining Consultants (see the company's news release dated July 24, 2025, for further information respecting the PEA), the Nevada North lithium project has a pit-constrained inferred resource containing an estimated 11.24 Mt (million tonnes) of lithium carbonate equivalent (LCE) grading 3,010 ppm (parts per million) Li at a 1,250 ppm cut-off. The PEA reported an after-tax NPV (net present value) 8 per cent $9.17-billion (U.S.) and after-tax IRR (internal rate of return) of 22.8 per cent at $24,000/t LCE (lithium carbonate equivalent) and opex (operating expenditure) of $5,243 (U.S.)/t LCE.
