One”)

Vancouver, Canada Euro Manganese Inc. (TSX-V and ASX: EMN; OTCQX: EUMNF ; Frankfurt: E06) (“Euro

Manganese”)

Highlights:

• The companies have jointly demonstrated cathode materials made directly from Euro Manganese

sourced electrolytic manganese metal using Nano One’s One-Pot Process.

• Euro Manganese has produced EV grade high -purity electrolytic manganese metal (“HPEMM”)

from its pilot plant using feedstock from its Chvaletice Manganese Project in the Czech Republic.

• Nano One’s patented One-Pot process enables cathode materials to be made directly from metals

(“M2CAM®”) and lithium carbonate, for reduced complexity, cost, and environmental footprint.

• Results align with automotive battery demands in Europe and North America for sustainably

sourced critical minerals and environmentally superior and differentiated supply chains.

Nano One® is a clean technology company with patented processes for the low-cost, low-environmental

footprint production of high -performance cathode materials used in lithium -ion batteries , a nd Euro

Manganese is a battery raw materials company developing a significant manganese deposit in the Czech

Republic. B oth companies are pleased to announce progress made under their J oint Development

Agreement.

The two companies are jointly developing e conomically viable and environmentally sustainable

applications of high- purity electrolytic manganese metal (“ HPEMM”) as one of several inputs for the

production of cathode active materials used in lithium -ion batteries. In this first milestone, pilot plant

samples from Euro Manganese’s Chvaletice Manganese Project have been successfully validated as

feedstock for Nano One’s patented One-Pot and M2CAM cathode production technolog ies. This avoids

the added cost, complexity, and environmental footprint of using metal sulphates in cathode production.

“We are demonstrating the production of cathode materials made directly from high purity metals,” said

Nano One CEO Mr. Dan Blondal, “and I am pleased to announce that we have now done so with electrolytic

manganese metal from Euro Manganese. This strategy eliminates capital and environmentally intensive

chemical conversion steps, eliminates large volumes of wasteful by-product and aligns us with legislation

in North America and Europe to fast-track battery supply chains from secure and readily available sources

of critical minerals. Nano One has ambitious plans to be a participant in the battery driven transformation

of mobility and renewable energy storage, and we are p leased to be blazing this trail with Euro

Manganese.”

Dr. Matthew James, Euro Manganese’s CEO, said, “We are delighted to be working with Nano One

on developing ways to use our manganese metal in its ground-breaking process for making cathode

active materials at a time when demand for high-purity manganese products is rising rapidly. Euro

Manganese’s production process, which has the flexibility to produce both a high purity manganese

metal product as well as a high purity manganese sulphate product, allows us to adapt to meet demand

from this important cost and environmental beneficial process developed by Nano One. Euro Manganese

stands to become the leading environmentally responsible producer of high purity battery grade

manganese products and we look forward to commissioning our larger demonstration plant at our

Chvaletice site in Q4 2022. We also look forward to a day when our manganese and Nano One’s

cathode materials are an integral part of the world’s battery supply chain and help cr eate a cleaner

world by enabling the green energy transition.”

About Nano One:

Nano One® Materials Corp (Nano One) is a clean technology company with a patented, scalable and low

carbon intensity industrial process for the low-c ost production of high-p erformance lithium-ion battery

cathode materials. The technology is applicable to electric vehicle, energy storage, consumer electronic

and next generation batteries in the global push for a zero-emission future. Nano One’s One-Pot process,

its coated nanocrystal materials and its Metal to Cathode Active Material (M2CAM®) technologies address

fundamental performance needs and supply chain constraints while reducing costs and carbon footprint.

Nano One has received funding from various government programs and the current “Scaling of Advanced

Battery Materials Project” is supported by Sustainable Development Technology Canada (SDTC) and the

Innovative Clean Energy (ICE) Fund of the Province of British Columbia. For more information, please visit

Changing how the world makes battery materials

About Euro Manganese:

Euro Manganese Inc. is a battery materials company focused on becoming a leading, competitive, and

environmentally superior producer of high-p urity manganese for the electric vehicle industry and other

high-technology applications. Euro Manganese is advancing development of the Chvaletice Manganese

Project in the Czech Republic, which is a unique waste-t o-value recycling and remediation opportunity

involving reprocessing old tailings from a decommissioned mine. The Chvaletice Project is the

only sizable resource of manganese in the European Union, strategically positioning it to provide

battery supply chains with critical raw materials to support the global shift to a circular, low-c arbon

economy. For more information, please visit www.mn25.ca.
