TORONTO, ON / ACCESSWIRE / April 9, 2024 / Electric Metals (USA) Limited ("EML" or the "Company") (TSXV:EML)(OTCQB:EMUSF) is pleased to announce the receipt of the expanded Mineral Resource Estimate for the 100% owned Emily Manganese Project in central Minnesota. Emily is the highest-grade manganese deposit in North America. The Mineral Resource was prepared in accordance with National Instrument 43‐101 ("NI 43‐101") by Forte Dynamics, Inc. ("Forte").

安大略省多伦多/ACCESSWIRE/2024年4月9日/电气金属（美国）有限公司（“EML” 或 “公司”）（多伦多证券交易所股票代码：EML）（OTCQB: EMUSF）欣然宣布，已收到明尼苏达州中部100％持股权的艾米丽锰项目的扩大的矿产资源估算。艾米丽是北美品位最高的锰矿床。矿产资源由Forte Dynamics, Inc.（“Forte”）根据国家仪器43‐101（“NI 43‐101”）制备。

The Mineral Resource Estimate is based on a geological model incorporating data from 29 diamond core holes drilled by Electric Metals in 2023 in the eastern and central portion of the Emily Manganese Deposit, and historical drilling data from 7 diamond core holes drilled in 2011 and 2012 in the eastern portion of the deposit. The drilling overlays a planned, but not executed, former U.S. Steel iron ore - manganese mine proposed in 1959. The current estimate confirms and expands the previous Mineral Resources. The current estimate is based on the most detailed geological model of the Emily Manganese deposit to date, which significantly enhances the understanding of grades and zonation within the deposit.

矿产资源估算基于地质模型，该模型纳入了2023年Electric Metals在艾米丽锰矿床东部和中部钻探的29个钻石岩心孔的数据，以及2011年和2012年在该矿床东部钻探的7个钻石岩心孔的历史钻探数据。该钻探覆盖了1959年拟建的前美国钢铁铁矿石锰矿山，但尚未执行。目前的估计证实并扩展了先前的矿产资源。目前的估计基于迄今为止艾米丽锰矿床最详细的地质模型，这极大地增强了对矿床内品位和区域划分的理解。

The Emily Manganese Deposit is in the northern portion of Minnesota's Cuyuna Iron Range in Crow Wing County, near the town of Emily. The Emily Deposit, a sedimentary iron deposit, is hosted by rocks of the Paleoproterozoic Animikie Basin, an early Proterozoic geologic terrane, which occupies much of east central Minnesota. The stratigraphy, structure, and high-grade manganese mineralization within these rocks is the result of long periods of sedimentation, deformation, and erosion along the ancestral southern margin of the Superior Craton. The Cuyuna Iron Range is traditionally divided into three districts, the Emily District, the North Range, and the South Range. While mined principally for iron ore, large quantities of manganese were extracted as manganiferous iron ores from several mines in the Cuyuna Iron Range from 1911 to 1967.

艾米丽锰矿床位于明尼苏达州克劳温县库尤纳铁岭的北部，靠近艾米丽镇。艾米丽矿床是一个沉积铁矿床，由古元古代阿尼米基盆地的岩石托管。古元古代阿尼米基盆地是早期的元古代地质地形，占据了明尼苏达州中东部的大部分地区。这些岩石中的地层、结构和高品位锰矿化是苏必利克拉通祖先南缘长期沉积、变形和侵蚀的结果。传统上，库尤纳铁岭分为三个地区，即艾米丽区、北山脉和南山脉。虽然主要开采铁矿石，但从1911年到1967年，大量锰是以锰铁矿石的形式从库尤纳铁山脉的几个矿山中提取的。

Further details supporting the geological model and the resource model estimation procedure will be available in an NI 43‐101 Technical Report disclosing the results of the Resource Estimate which will be posted under the Company's profile at within 45 days.

支持地质模型和资源模型估算程序的更多详细信息将在NI 43‐101技术报告中提供，该报告将披露资源估算的结果，该报告将在45天内在公司简介下发布。

Brian Savage, CEO, Electric Metals, commented "We're thrilled to announce the expanded Mineral Resource Estimate for our Emily Manganese Project in Minnesota, solidifying our position as a key player in North America's manganese market. This significant increase in both Indicated and Inferred Resources underscores our dedication to maximizing the potential of the deposit. Our next objectives include conducting further drilling to progress these resources into a mineable reserve and conducting additional metallurgical testing to refine and optimize the flow sheet."

Electric Metals首席执行官布莱恩·萨维奇评论说：“我们很高兴地宣布扩大明尼苏达州艾米丽锰项目的矿产资源估算，巩固了我们作为北美锰市场关键参与者的地位。指示资源和推断资源的显著增加凸显了我们致力于最大限度地发挥存款潜力的决心。我们的下一个目标包括进行进一步的钻探以将这些资源开采到可开采的储量中，并进行额外的冶金测试以完善和优化流程表。”

Block Model

方块模型

The block model used for resource estimation is a 4m x 2m x 1.5m, orthogonal, non-rotated block model. Block grade estimation was completed using LeapFrog Edge software. Grade estimates use inverse distance to the second power (ID2), within each domain. Blocks were estimated with a single pass search at about 1.5 variogram ranges for the Mn domains, and 1.5 of the variogram ranges for the Fe and SiO2 domains.

用于资源估算的分组模型是 4m x 2m x 1.5m、正交的、非旋转的区块模型。区块等级估算是使用 LeapFrog Edge 软件完成的。等级估算使用每个域内与第二次方 (ID2) 的反向距离。区块是通过单次搜索估算出的，锰结构域的变异函数范围约为 1.5，铁和二氧化硅结构域的变异函数范围为 1.5。

Potential cutoff grades for the models were estimated using U.S. $100 - $160/tonne for mining, processing, and administrative costs, a 95% Mn recovery rate, and U.S. $1,000 - $3,000/tonne for the sales price of battery grade manganese sulphate monohydrate (MnSO4).

据估计，这些模型的潜在截止等级为每吨100至160美元，用于采矿、加工和管理成本，95％的回收率，电池级硫酸锰一水合物的销售价格为1,000至3,000美元（mnSO）的销售价格为每吨1,000至3,000美元4)。

Based on these ranges the QP estimated potential cutoff grades in percent contained manganese and the sensitivity is shown in Table 2. This shows a range of cutoff grades from 2% to 6% Mn. Although there is a sizable mineral resource above 5% manganese, the mineral processing consultants have indicated that certain efficiencies are possible with higher feed grades. Due to the nature of the deposit, there is a continuous core of material greater than 10% that results in an average grade of ~18%, potentially bringing these efficiencies to the operation. The QP suggests that the mineral resource be reported at 5% Manganese while evaluating the potential of higher grade.

基于这些范围，QP以含锰百分比估算了潜在的截止等级，灵敏度如表2所示。这显示了从 2% 到 6% 锰的截止品位范围。尽管锰含量高于 5% 的大量矿产资源，但矿物加工顾问表示，提高饲料等级可以提高一定的效率。由于沉积物的性质，连续的材料堆芯大于10％，因此平均品位约为18％，这有可能为运营带来这些效率。QP建议，在评估更高品位的潜力时，矿产资源的锰含量应为5％。

Notes:

注意事项：

  1. Variable operating costs were utilized in the models, from U.S. $100 - $160/tonne for mining, processing, and administrative costs.
  2. Value was only attributed to manganese, with variable product pricing from U.S. $1,000 - $3,000/tonne for battery grade manganese sulphate monohydrate (MnSO4).
  1. 模型中采用了可变的运营成本，采矿、加工和管理费用从100美元到每吨160美元不等。
  2. 价值仅归因于锰，电池级硫酸锰一水合物（mnSO）的产品定价从每吨1,000美元到3,000美元不等4)。

A visual review of the block model shows good agreement between block and composite grades.

对区块模型的直观审查显示，分组和复合成绩之间存在良好的一致性。

About Electric Metals (USA) Limited

关于电气金属（美国）有限公司

Electric Metals (USA) Limited (TSXV:EML)(OTCQB:EMUSF) is a U.S.-based mineral development company with manganese and silver projects geared to supporting the transition to clean energy. The Company's principal asset is the Emily Manganese Project in Minnesota, which has been the subject of considerable technical studies, including a National Instrument 43-101 Technical Report - Resource Estimate, with over US$26 million invested to date. The Company's mission in Minnesota is to become a domestic U.S. producer of high purity, high value manganese metal and chemical products for supply to U.S. energy, technology and industrial markets. With manganese playing a critical and prominent role in lithium-ion battery formulations, and with no current domestic supply or active mines for manganese in North America, the development of the Emily Manganese Project represents a significant opportunity for America, the State of Minnesota and for the Company's shareholders.

电气金属（美国）有限公司（多伦多证券交易所股票代码：EML）（OTCQB: EMUSF）是一家总部位于美国的矿产开发公司，其锰和白银项目旨在支持向清洁能源的过渡。该公司的主要资产是明尼苏达州的艾米丽锰项目，该项目一直是大量技术研究的主题，包括国家仪器43-101技术报告——资源估算，迄今已投资超过2600万美元。该公司在明尼苏达州的使命是成为美国本土的高纯度、高价值金属锰和化学产品的生产商，供应给美国能源、技术和工业市场。由于锰在锂离子电池配方中起着至关重要的作用，而且北美目前没有国内锰供应或活跃的矿山，艾米丽锰项目的开发对美国、明尼苏达州和公司股东来说都是一个重大机遇。
