The results show that particle-scale ore\nsorting upgraded a drill core dataset, averaging approximately 8.2% Mn, to\napproximately 17.5% Mn while recovering approximately 92% of the contained\nmanganese. This means 57% of the material could potentially be rejected prior\nto downstream processing while retaining approximately 92% of the contained\nmanganese.\n\n\"These results demonstrate that ore sorting has the potential to be a\nsignificant value-enhancing technology for the Emily Manganese Deposit,\" said\nBrian Savage, Chief Executive Officer of Electric Metals. \"The work\ndemonstrates that material previously below our 10% cut-off grade could be\nupgraded to the same grade contemplated in our current development plan for\nthe Emily Deposit, highlighting the potential for ore sorting to turn\nsub-cut-off mineralization into economic ore, subject to further economic\nevaluation.\"\n\nThe work supports Electric Metals' strategy of evaluating advanced\nsensor-based pre-concentration technologies capable of upgrading ore feed\ngrade, reducing downstream processing costs, improving project economics and\nenhancing the utilization of mineralized material within the deposit.\n\nThe evaluation utilized the Rados XRF+ Drill Core Analyzer (\"DCA\"), which\nscanned approximately 4,200 feet of drill core from 18 drill holes at high\nresolution. The resulting dataset was calibrated against laboratory assays and\nused to simulate the performance of XRF-based ore sorting under a range of\noperating scenarios. The results demonstrate that the Emily manganese\nmineralization exhibits the grade variability and geological characteristics\nrequired for successful sensor-based ore sorting.\n\nFor a project like what is being explored in Emily, the results could\ntranslate into lower transportation, crushing, grinding, leaching, reagent\nconsumption, material handling and tailings management costs while improving\noverall project economics. The technology may also help mitigate mining\ndilution and provide additional flexibility in mine planning and resource\nutilization.\n\nThe study also confirms that the Emily Deposit exhibits the degree of natural\ngeological variability required for commercial-scale ore sorting applications.\nRados concluded that the Emily Deposit is technically well suited to both\nXRF-based particle sorting and bulk ore sorting and recommended further\nengineering and economic evaluation.\n\nThe Company intends to incorporate the results into ongoing engineering\nstudies evaluating the optimal development pathway for the Emily Manganese\nDeposit and the broader North Star Manganese Project, which aims to establish\na fully domestic U.S. supply chain for high-purity manganese products used in\nelectric vehicle batteries, energy storage systems, defense applications,\ntechnology applications and industrial markets.\n(https://app.accessnewswire.com/imagelibrary/6195f684-c49f-4ded-bb94-d23b22ceda5a/1184388/jpg.jpeg)\nRados DCA Setup at the North Star Manganese Project Core Storage Facility in\nEmily, Minnesota\n\nHighlights\n*\nSimulated particle-scale ore sorting upgraded a drill core dataset, averaging\napproximately 8.2% Mn to approximately 17.5% Mn while recovering approximately\n92% of the contained manganese.\n*\nApproximately 57% of the material could potentially be rejected prior to\ndownstream processing while retaining approximately 92% of the contained\nmanganese.\n*\nThe study demonstrates the potential for sensor-based pre-concentration to\nenhance the economic utilization of lower-grade mineralized material.\n*\nSimulated bulk ore sorting upgraded a drill core dataset averaging\napproximately 8.2% Mn to approximately 13.1% Mn while recovering approximately\n92% of contained manganese.\n*\nHigher-selectivity simulated sorting scenario at an 18% threshold produced\nconcentrate grades approaching 33% Mn.\n*\nProgressive rejection of iron-bearing material was observed in simulated\nsorting scenarios at higher manganese thresholds, indicating potential\ndownstream metallurgical benefits.\n*\nStrong short-range manganese variability is confirmed throughout the deposit,\na key prerequisite for successful sensor-based ore sorting.\n*\nExcellent correlation between XRF measurements and laboratory assays, with\ncalibration accuracy of approximately R² = 0.97 for manganese and R² = 0.98\nfor iron.\n*\nMore than 132,000 particle-scale measurements collected from approximately\n4,200 feet of drill core across 18 drill holes.\n\nWhat Makes This Result Important?\n\n Metric                                                                                                                        Mn Grade                   \n Current Emily Resource Cutoff Grade                                                                                           10.0% Mn                   \n Current Emily Resource Grade - Indicated Current Emily Resource Grade - Inferred Average Grade of Dataset Evaluated by Rados  19.3% Mn 17.5% Mn 8.2% Mn  \n Simulated Ore Sorting Product Grade                                                                                           17.5% Mn                   \n Simulated Manganese Recovery                                                                                                  92%                        \n\nWhile the reported sorting results are based on numerical simulations\ncalibrated against laboratory assays rather than physical sorting trials, the\nstudy demonstrates that material averaging below the Company's current\nresource cutoff grade may potentially be upgraded to a grade substantially\nabove the cutoff while retaining approximately 92% of the contained manganese.\n\nIn simulated ore sorting scenarios based on more than 132,000 high-resolution\nXRF measurements, manganese feed grade more than doubled while recovering\napproximately 92% of the contained manganese and rejecting more than half of\nthe material before it entered the processing circuit.\n\nThe study also confirmed the short-range grade variability required for\nsuccessful ore sorting and demonstrated that the technology can accurately\ndistinguish between higher-grade and lower-grade manganese-bearing material.\n\nPerhaps most importantly, these results suggest that ore sorting may provide a\npathway to economically utilize portions of the deposit that would otherwise\nbe difficult to process efficiently. If confirmed through future physical test\nwork, engineering studies and economic evaluations, this could materially\nenhance project economics and improve resource utilization.\"\n\nA particularly significant outcome of the study is that the dataset evaluated\nby Rados averaged approximately 8.2% Mn. Through simulated ore sorting, that\nmaterial was upgraded to approximately 17.5% Mn while recovering approximately\n92% of the contained manganese. These results suggest that ore sorting may\nprovide a pathway to economically utilize lower-grade portions of the deposit\nwhile preserving manganese recovery.\n\nIn a simulated particle-scale sorting scenario at a 10 mm size fraction and a\n4% Mn sorting threshold, manganese grade was upgraded from approximately 8.2%\nMn to 17.5% Mn while recovering approximately 92% of the contained manganese.\nAt this operating point, approximately 57% of the material was rejected while\nretaining the vast majority of the contained manganese.\n\nUnder a simulated bulk ore sorting scenario at the same 4% Mn cut-off,\nmanganese grade increased from approximately 8.2% Mn to 13.1% Mn while\nrecovering approximately 92% of the contained manganese. These results\ndemonstrate the potential for meaningful pre-concentration before downstream\nprocessing and indicate that substantial waste rejection can be achieved while\npreserving manganese recovery.\n\nAt a more selective simulated sorting threshold of 18%, particle sorting\nscenarios achieved concentrate grades approaching 33% Mn, demonstrating the\npotential to produce a high-grade manganese concentrate. The results\nillustrate a range of operating scenarios that can be optimized in future\nengineering studies depending on project objectives and economic conditions.\n\nThe study also demonstrated that iron increasingly reports to the discard\nstream at higher manganese sorting thresholds, suggesting that ore sorting may\nprovide additional metallurgical benefits through the early rejection of\niron-bearing material before hydrometallurgical processing.\n\nThese preliminary results suggest that the Emily Manganese Deposit is amenable\nto XRF-based pre-concentration. The successful deployment of pre-concentration\nmethods such as ore sorting could provide the opportunity for:\n*\nLow-impact manganese upgrading utilizing physical separation processes without\nchemicals or water consumption;\n*\nReduction of ore shipment volumes through removal of gangue and low-grade\nmaterial prior to processing;\n*\nPotential reductions in crushing, grinding, reagent consumption, material\nhandling requirements and tailings generation; and\n*\nPotential enhancement of overall project economics through improved feed grade\nand waste rejection.\n\nAbout the Test Program\nThe ore sorting assessment was completed by Rados International Technologies\nusing its proprietary XRF+ Drill Core Analyzer. A total of 684 drill core\ntrays representing approximately 4,200 feet of core from 18 drill holes were\nscanned at 10 mm intervals. The resulting dataset was calibrated against\nlaboratory assays and used to estimate sorter performance through numerical\nsimulation of multiple operating scenarios. No physical ore sorting trials\nwere conducted as part of this program. The study concluded that the Emily\nDeposit is technically well suited to XRF-based ore sorting and identified\nclear opportunities for manganese grade upgrading and waste rejection prior to\nprocessing.\n\nThe results reported herein are based on simulated ore sorting performance\nderived from high-resolution XRF analysis of drill core and calibration\nagainst laboratory assays.

Litigation is inherently\nuncertain, and the Company cannot predict the outcome or timing of the matter.\nAn adverse determination could have a material adverse effect on the Company's\ninterest in the Emily manganese project and on the Company.\n\nAbout Electric Metals USA Limited\nElectric Metals (USA) Limited (TSXV:EML)(OTCQB:EMUS) is a U.S.-domiciled\ncritical minerals and advanced materials company developing the North Star\nManganese Project to establish a fully domestic U.S. supply of high-purity\nmanganese products for battery, defense, infrastructure, technology, and\nindustrial markets.\n\nThe Company's principal asset is the Emily manganese deposit in Minnesota, the\nhighest-grade manganese deposit in North America. The North Star Manganese\nProject is a 100% U.S. domestic project comprising a manganese mine in Emily,\nMinnesota, and a U.S.-based processing facility designed to produce\nhigh-purity manganese sulfate monohydrate (HPMSM) and electrolytic manganese\nmetal (EMM). The project has been the subject of extensive technical work,\nincluding a Preliminary Economic Assessment prepared in accordance with\nNational Instrument 43-101 Standards of Disclosure for Mineral Projects.\n\nElectric Metals' mission is to strengthen America's critical mineral\nindependence by developing a secure domestic supply of high-purity manganese\nchemical and metal products for North American electric vehicle and energy\nstorage batteries, defense applications, critical infrastructure, specialty\nalloys, advanced technologies, and industrial uses.\n\nWith manganese playing an increasingly important role in lithium-ion battery\nformulations and with no current domestic U.S. production of manganese ore,\nHPMSM, or EMM, the development of the North Star Manganese Project represents\na strategic opportunity to reduce dependence on foreign supply chains and\nsupport U.S. industrial, energy, and national security priorities.\n\nFor further information, please contact:\nElectric Metals (USA) Limited\nBrian Savage\nChief Executive Officer & Director\n(303) 656‑9197\n\nForward‑Looking Information\nThis news release contains \"forward-looking information\" and \"forward-looking\nstatements\" (collectively, \"forward-looking information\") within the meaning\nof applicable securities laws.
