Lithium One Acquires Six Strategic Lithium Properties in Northern Ontario

Vancouver, December 21, 2022 - Lithium One Metals Inc. (TSXV: LONE) (FSE: H490) (the "Company" or "Lithium One") is pleased to announce it has entered into Option Agreements to acquire six lithium properties in the Red Lake and Thunder Bay Mining Divisions in northwest Ontario (Figure 1). The properties add 23,250 ha to Lithium One's portfolio of lithium assets in emerging lithium camps in Ontario and Quebec.

Acquisition Highlights

• Root South Lithium Property. Root South is adjacent to the Root Project, which is owned by Green Technology Metals who recently announced a 24,000 m drill program on their 2Mt McCombe lithium deposit averaging 1.3% Li₂O (Figure 2). The Root South project has several mapped pegmatite showings and has a limited lithium exploration history.

• The Parks Lithium Project. Parks is located in the Barbara Lake pegmatite field and is within 10 km east of the Georgia Lake Project owned by Rock Tech Lithium (Figure 3).

• Allison South Lithium Project. Allison South is located on the edge of the Allison Lake Batholith in an area identified by government mapping for its high potential for lithium exploration. The property is also adjacent to the Allison Lithium Project, owned by Green Technology Metals.

• Prospective Geology for Lithium Exploration. All six properties are located near geological subprovince boundaries and feature mapped pegmatites with peraluminous S-type fertile granites. These terrane boundaries are deep seated sutures that act as conduits for fertile peraluminous granites, and lithium projects in Ontario are overwhelmingly located within 20 km of a terrane boundary.

• Planned Work Programs. In Spring 2023, the Company will commence an exploration campaign, with the initial focus on prospecting, mapping, and sampling pegmatites.

Root South Lithium Property

The Root South Lithium Property is located in the Red Lake Mining Division, 90 km northeast of Sioux Lookout, Ontario with good highway and logging road access. It is adjacent to the Root Lithium Project owned by Green Technology Metals who recently announced a 24,000 m drill program on their 2Mt lithium deposit averaging 1.3% Li₂O. It consists of 175 claims covering 3,570 ha.

The Root South Lithium Property is underlain by peraluminous, S-type fertile granite with multiple pegmatites mapped on the property and registered lithium mineral occurrences on trend to the northwest.

The Root South Property is located 1 km from the terrain boundary between the Uchi Subprovince and the English River Subprovince. These terrane boundaries are deep seated sutures that act as conduits for fertile peraluminous granites, and lithium projects in Ontario are overwhelmingly located within 20 km of a terrane boundary.

Parks Lithium Property

The Parks Lithium Property is located 55 km northeast of Nipigon, Ontario with good highway and logging road access. It is 8 km from the Georgia Lake Lithium Project where a recently completed pre-feasibility study outlined a resource of 10.6 million tons grading 0.88% Li₂O. It consists of 472 claims over 9,939 Ha.

The Parks Lithium Property is within the Barbara Lake pegmatite field and is underlain by peraluminous, S-type fertile granite, diabase, and metasediments which make excellent exo-contact hosts for fractionating parental granites. Pegmatites have been previously mapped on the property and there are registered lithium mineral occurrences on trend to the southwest and northeast.

Allison South Lithium Property

The Allison South Lithium Property is located in the Red Lake Mining Division, 100 km east of Red Lake, Ontario with good highway and logging road access. It is adjacent to the Allison Lithium Project owned by Green Technology Metals, and 40 km southeast of their Root Lithium Project. It consists of 58 claims covering 1,180 ha.

The Allison South Lithium Property is underlain by the Allison Lake Batholith, a peraluminous, S-type fertile granite with multiple pink and white pegmatites mapped on the property and registered lithium mineral occurrences on trend to the northwest and southeast. The margins of the batholith have been identified by government mapping as an underexplored and highly prospective area.

The Allison South Lithium Property is located 10 km from the terrain boundary between the Uchi Subprovince and the English River Subprovince. These terrane boundaries are deep seated sutures that act as conduits for fertile peraluminous granites, and lithium projects in Ontario are overwhelmingly located within 20 km of a terrane boundary.

Sharp Lithium Property

The Sharp Lithium Property is located in the Red Lake Mining Division, 115 km southeast of Red Lake, Ontario, and 26 km southwest of the Root Lithium Project owned by Green Technology Metals. It consists of 158 claims covering 3,225 ha.

The Sharp Lithium Property is underlain by peraluminous, S-type fertile granite and metasediments which make excellent exo-contact hosts for fractionating parental granites. The property is located 4 km from the terrain boundary between the Uchi Subprovince and the English River Subprovince. The English River Subprovince is historically underexplored for lithium despite favourable results from lake sediment sampling.

Dagny Lithium Property

The Dagny Lithium Property is located in the Red Lake Mining Division, 50 km north of Sioux Lookout, Ontario with good highway and logging road access. It is 42 km south of the Root Lithium Project owned by Green Technology Metals. It consists of 123 claims covering 2,515 ha.

The Dagny Lithium Property is underlain by peraluminous S-type fertile granite and metasediments which make excellent exo-contact hosts for fractionating parental granites. Pegmatites have been previously mapped on the property, and a northeast trending structure mapped across the property is high priority to investigate as a conduit for parental melts.

The Dagny Lithium Property is located 8 km from the terrain boundary between the Winnipeg River Subprovince and the English River Subprovince.

Adamhay Lithium Property

The Adamhay Lithium Property is located in the Red Lake Mining Division, 70 km north of Sioux Lookout, Ontario and 22 km southwest of the Root Lithium Project owned by Green Technology Metals. It consists of 138 claims covering 2,813 ha.

The Adamhay Lithium Property is underlain by peraluminous S-type fertile granite and metasediments which make excellent exo-contact hosts for fractionating parental granites. Pegmatites have been previously mapped on the property, and northeast trending structures mapped across the property are high priority to investigate as conduits for parental melts.

The Adamhay Lithium Property is located 19 km from the terrain boundary between the Uchi Subprovince and the English River Subprovince.
