Electric Metals Files the Upgraded Emily, Minnesota Manganese Project Ni 43-101 Technical Report Confirming the Highest Grade Manganese Resource IN North America
ELECTRIC METALS FILES THE UPGRADED EMILY,
MINNESOTA MANGANESE PROJECT NI 43-101 TECHNICAL REPORT
CONFIRMING THE HIGHEST GRADE MANGANESE RESOURCE IN NORTH AMERICA
• At a 10% cutoff grade, Indicated Resources increased by 20.9% to 6.2 million metric tons, with
a grade of 19.27% manganese, and Inferred Resources increased by 596.5% to 4.9 million
metric tons, with a grade of 17.50% manganese
• Large tonnage expansion associated with eastern in-fill and central step-out drill holes, the
western zone of the deposit remains open and is recommended for expansion
• 29 new holes drilled, 22 of which reported substantial zones of +25% manganese, and 19 new
drill holes reported significant intercepts of 35% to +50% manganese
• Current manganese extractions exceeding 95% recovery, with testing ongoing
TORONTO, ONT, May 27, 2024 – Electric Metals (USA) Limited (“Electric Metals”, “EML” or the
“Company”) (TSXV: EML) (OTCQB: EMUSF) is pleased to announce the filing of the upgraded
Mineral Resource Estimate for the 100% owned Emily Manganese Project in central Minnesota.
The Mineral Resource Estimate was prepared in accordance with National Instrument 43-101 (“NI
43-101”) by Forte Dynamics, Inc. (“Forte”).
The upgraded Mineral Resource Estimate is based on a geological model incorporating data from
the 2023 drilling program by North Star Manganese Inc (NSM), a subsidiary of the Company, and
historical drilling in 2011 and 2012. The estimate confirms and expands the previous Mineral
Resource Estimate from 2022. Results of the upgraded Mineral Resource Estimate (T able 1) are as
follows:

Brian Savage, CEO, Electric Metals, commented “We are pleased to file the upgraded NI 43-101
Mineral Resource Estimate for our Emily Manganese Project in Minnesota, confirming the highest
grade manganese resource in North America and solidifying our position as a key player in North
America's manganese market. Our plan going forward is to convert these resources into high-
grade mineable reserves, and to advance the metallurgical testing to refine and optimize the flow
sheet for the production of high-value, high-grade manganese chemicals and products.”
NI 43-101 Technical Report and Project Highlights
The upgraded Mineral Resource Estimate is based on a geological model incorporating data from
29 diamond core holes drilled by NSM 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, as shown in Figure 1.
Figure 1. Map of Drillholes and Emily Property Boundary
Both the recent drilling and historical drilling are following the known iron and manganese
(manganiferous iron ore) Emily formation initially identified in 1913. After discovery of the Emily
formation by the Pickands Mather Mining Company in the 1940s, historic drilling was performed
by U.S. Steel in the 1950s, and others in the 1990s and 2011-2.
This historic work continued to support the premise that a potentially significant endowment of
manganese exists in this area. As reconfirmed by the NSM drilling in 2023, the manganiferous
iron ore zones demonstrate consistency, as shown in Figure 2, which represents an east to west
cross section of the updated 2023 drilling.
Figure 2. 2023 Drill Program – East to West Cross Section
The East to West Cross Section information was previously reported in the October 31, 2023 Electric Metals
(USA) Limited press release.
Figure 3 represents a south to north stratigraphic profile of the Emily Deposit. Big Rock
Exploration, consulting geologists on the project, were able to confirm the lateral and down dip
extensions of manganese mineralization, as shown below.
Figure 3. Emily Deposit – Schematic Stratigraphic Profile
The above profile shows the Paleoproterozoic Emily Iron Formations (Peif), Peif1 through Peif5, and Peif1r,
including the overburden and bedrock. The Mineral Resource Estimate was confined by Forte to zones Peif1
(including Peif1r), Peif2, and Peif3. The deposit is open laterally and at depth (downdip); the deepest hole is
at 200 meters (656 feet).
A majority of the current drill holes intercepted substantial zones of elevated manganese grades
ranging from +25% manganese to +50% manganese. These values were capped within the three
primary mineralized domains modeled by Forte, Peif1 (including Peif1r), Peif2, and Peif3. An
example of the high grade manganese mineralization is shown in Figure 4.
The zones demonstrated good continuity, and mineralization X-ray diffraction (XRD) results
identified the main manganese-bearing minerals as manganite, braunite and cryptomelane, with
hematite and subordinate goethite being the main iron-bearing minerals.

Above is a portion of a 5.39-meter-wide drill intersection (17.7 feet) between 62.88 and 68.28 meters which
averaged 44.5% Mn, previously reported in the July 13, 2023 Electric Metals (USA) Limited press release.
“Seeing the high grade come out as polished ‘near-metal’ is truly exciting. We have a number of
core samples that exceeded 50 percent manganese – a grade not found in North America and
most of the rest of the world”, said Brian Savage.
Next Steps
We are developing a drill program to upgrade resources to reserves, facilitate mine permitting,
mine planning, additional metallurgical test work and flow sheet optimization. We will also be
undertaking studies to determine potential sites for the HPMSM plant and to perform a scoping
or pre-feasibility level study for the HPMSM plant.

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 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 National Instrument 43-101 T echnical Reports
– Resource Estimates. The Company’s mission in Minnesota is to become a domestic U.S. producer
of high purity, high value manganese metal and chemical products to supply the North American
electric vehicle battery, technology and industrial markets. With manganese playing a critical and
prominent role in lithium-ion battery formulations, and with no domestic supply or active
manganese mines 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.
