Electric Metals (USA) Limited Updates Emily Manganese Deposit Metallurgical Test Work
| ELECTRIC METALS (USA) LIMITED UPDATES EMILY MANGANESE DEPOSIT METALLURGICAL TEST WORK | |||
|---|---|---|---|
| • Current direct leaching results successful in achieving high manganese extractions of more than 90% using a reductant • Previous leach test work confirmed +80% recovery of manganese and produced a number of chemical grade manganese products including EMD, EMM, and MnCO in the lab 3 • Focus is now on developing a viable optimized flow sheet Toronto, Ontario, April 22, 2024 – Electric Metals (USA) Limited (“EML” or the “Company”) (TSXV: EML) (OTCQB: EMUSF) is pleased to provide a review and progress report on the manganese metallurgical test work with Kemetco Research Inc., of Richmond, BC, Canada, from samples obtained from the Company’s Emily manganese deposit, located in central Minnesota. Kemetco is one the leading metallurgical firms specializing in the extracWon and processing of manganese ores and compounds worldwide. As reported in the 2022 NI 43-101, Kemetco was commissioned in 2013 to undertake parametric leach tests on Emily manganese ore to provide an iniWal determinaWon of leaching condiWons and the ulWmate manganese recovery potenWal. Using a leaching protocol that uWlizes SO as a reducing agent, Kemetco 2 demonstrated that more than 80% of the manganese could be recovered from the feed without requiring pre-concentraWon. Kemetco also performed a larger batch leach and used the purified leach soluWon in laboratory-scale electrowinning to produce of chemical grade manganese dioxide (MnO ), electrolyWc 2 manganese metal (EMM) and chemical grade manganese carbonate (MnCO ). 3 In 2023, Electric Metals recommissioned Kemetco to conWnue working on the metallurgy and commercial processing. The 2023-4 metallurgical test work at Kemetco uWlized two manganese composites weighing approximately 228 kilograms taken from 40 samples: | |||

- Higher grade whole rock composite sample (37.0% Mn, 19.03% Fe, and 4.61% SiO2), and
- Lower grade whole rock composite sample (15.57% Mn, 20.61% Fe, and 38.45% SiO2)
The leach opWmizaWon tests are leveraging off of the earlier studies and have been conducted to determine appropriate condiWons and likely leach yields. The acid leach tests indicate that high manganese extracWons recovered more than 90% manganese using a reductant. The metallurgical test work is ongoing with expectaWons of developing a viable process flowsheet for the project in the coming months. Future work will focus on the opWmizaWon of the proposed approaches.
This work has been conducted to determine what products can be economically produced from Emily ore, including High Purity Manganese Sulphate Monohydrate (HPMSM) which is essenWal and a major component to electric vehicle (EV) baieries, rechargeable baieries, and other emerging energy storage applicaWons.
| Brian Savage, CEO, Electric Metals, commented “we are very pleased to be | working with Kemetco, a |
| renowned metallurgical laboratory, to advance the Emily manganese deposit metallurgical test work. Our | |
| focus is on producing HPMSM, crucial for the EV baiery sector, and other high-value manganese | |
| chemicals. We look forward to conWnued posiWve results”. |

About Electric Metals (USA) Limited
Electric Metals (USA) Limited (TSXV: EML) (OTCQB: EMUSF) is a U.S.-based mineral development company with manganese and silver projects geared to supporWng the transiWon 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 NaWonal Instrument 43-101 Technical Report – Resource EsWmate, with over US$26 million invested to date. The Company’s mission in Minnesota is to become a domesWc 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 criWcal and prominent role in lithium-ion baiery formulaWons, and with no current domesWc supply or acWve 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.
