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").

安大略省多倫多/ACCESSWIRE/2024年4月9日/電氣金屬（美國）有限公司（“EML” 或 “公司”）（多倫多證券交易所股票代碼：EML）（OTCQB: EMUSF）欣然宣佈，已收到明尼蘇達州中部100％持股權的艾米麗錳項目的擴大的礦產資源估算。艾米麗是北美品位最高的錳礦牀。礦產資源由Forte Dynamics, Inc.（“Forte”）根據國家儀器43‐101（“NI 43‐101”）製備。

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.

礦產資源估算基於地質模型，該模型納入了2023年Electric Metals在艾米麗錳礦牀東部和中部鑽探的29個鑽石岩心孔的數據，以及2011年和2012年在該礦牀東部鑽探的7個鑽石岩心孔的歷史鑽探數據。該鑽探覆蓋了1959年擬建的前美國鋼鐵鐵礦石錳礦山，但尚未執行。目前的估計證實並擴展了先前的礦產資源。目前的估計基於迄今爲止艾米麗錳礦牀最詳細的地質模型，這極大地增強了對礦牀內品位和區域劃分的理解。

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.

艾米麗錳礦牀位於明尼蘇達州克勞溫縣庫尤納鐵嶺的北部，靠近艾米麗鎮。艾米麗礦牀是一個沉積鐵礦牀，由古元古代阿尼米基盆地的岩石託管。古元古代阿尼米基盆地是早期的元古代地質地形，佔據了明尼蘇達州中東部的大部分地區。這些岩石中的地層、結構和高品位錳礦化是蘇必利克拉通祖先南緣長期沉積、變形和侵蝕的結果。傳統上，庫尤納鐵嶺分爲三個地區，即艾米麗區、北山脈和南山脈。雖然主要開採鐵礦石，但從1911年到1967年，大量錳是以錳鐵礦石的形式從庫尤納鐵山脈的幾個礦山中提取的。

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.

支持地質模型和資源模型估算程序的更多詳細信息將在NI 43‐101技術報告中提供，該報告將披露資源估算的結果，該報告將在45天內在公司簡介下發布。

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首席執行官布萊恩·薩維奇評論說：“我們很高興地宣佈擴大明尼蘇達州艾米麗錳項目的礦產資源估算，鞏固了我們作爲北美錳市場關鍵參與者的地位。指示資源和推斷資源的顯著增加凸顯了我們致力於最大限度地發揮存款潛力的決心。我們的下一個目標包括進行進一步的鑽探以將這些資源開採到可開採的儲量中，並進行額外的冶金測試以完善和優化流程表。”

Block Model

方塊模型

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.

用於資源估算的分組模型是 4m x 2m x 1.5m、正交的、非旋轉的區塊模型。區塊等級估算是使用 LeapFrog Edge 軟件完成的。等級估算使用每個域內與第二次方 (ID2) 的反向距離。區塊是通過單次搜索估算出的，錳結構域的變異函數範圍約爲 1.5，鐵和二氧化硅結構域的變異函數範圍爲 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).

據估計，這些模型的潛在截止等級爲每噸100至160美元，用於採礦、加工和管理成本，95％的回收率，電池級硫酸錳一水合物的銷售價格爲1,000至3,000美元（mnSO）的銷售價格爲每噸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.

基於這些範圍，QP以含錳百分比估算了潛在的截止等級，靈敏度如表2所示。這顯示了從 2% 到 6% 錳的截止品位範圍。儘管錳含量高於 5% 的大量礦產資源，但礦物加工顧問表示，提高飼料等級可以提高一定的效率。由於沉積物的性質，連續的材料堆芯大於10％，因此平均品位約爲18％，這有可能爲運營帶來這些效率。QP建議，在評估更高品位的潛力時，礦產資源的錳含量應爲5％。

Notes:

注意事項：

  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. 模型中採用了可變的運營成本，採礦、加工和管理費用從100美元到每噸160美元不等。
  2. 價值僅歸因於錳，電池級硫酸錳一水合物（mnSO）的產品定價從每噸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.

對區塊模型的直觀審查顯示，分組和複合成績之間存在良好的一致性。

About Electric Metals (USA) Limited

關於電氣金屬（美國）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.

電氣金屬（美國）有限公司（多倫多證券交易所股票代碼：EML）（OTCQB: EMUSF）是一家總部位於美國的礦產開發公司，其錳和白銀項目旨在支持向清潔能源的過渡。該公司的主要資產是明尼蘇達州的艾米麗錳項目，該項目一直是大量技術研究的主題，包括國家儀器43-101技術報告——資源估算，迄今已投資超過2600萬美元。該公司在明尼蘇達州的使命是成爲美國本土的高純度、高價值金屬錳和化學產品的生產商，供應給美國能源、技術和工業市場。由於錳在鋰離子電池配方中起着至關重要的作用，而且北美目前沒有國內錳供應或活躍的礦山，艾米麗錳項目的開發對美國、明尼蘇達州和公司股東來說都是一個重大機遇。
