United Lithium Corp. Announces Lithium Extraction and Purification Development Agreement for its Bergby Lithium Project in Sweden

VANCOUVER, March 25, 2021 - United Lithium Corp. (CSE:ULTH)(OTC PINK:ULTHF)( FWB:0UL) (the "Company" or "United Lithium"), is pleased to announce it has signed a partnership with Process Research Ortech Inc. ("Ortech") of Mississauga, Canada, to develop a leaching and purification protocol for hard rock lithium deposits.

The proposed work program will develop preliminary mineral processing and metallurgical process flow-sheets for the recovery of lithium from hard rock spodumene mineralization. The development of this process will allow the Company to move towards commercialization of lithium extraction and purification from spodumene through a pilot project. The Company anticipates the program will require approximately 16-22 weeks from engagement to full completion and results.

Ortech will work with United Lithium to undertake the following steps for completion of Phase I;

• Mineral processing (Spodumene/Petalite)

• Impurity removal (i.e., Al, Fe, Si, Mn, Zn, Mg and Ca)

• Product recovery (lithium carbonate (Li₂CO₃))

This test work will lead to the development and evaluation of an initial process flow-sheet for optimization in subsequent research, which will involve a mini pilot plant test program to obtain preliminary process design criteria and economic feasibility data.

Background information

Lithium (Li) is one of the important strategic metals due to its increasing use in emerging technologies, especially batteries for plug-in hybrid, electric and hybrid electric vehicles, portable electronics and energy storage. High purity lithium carbonate (Li₂CO₃) is used as a raw material to produce these batteries. Currently, ~35% of global lithium production is being used in lithium ion batteries (LIBs) and consumption for estimated LIB demand could be 66% by 2025. High-grade lithium hard rocks/ores and brine are the present sources for commercial lithium production. More than 80% of the lithium is produced from brine due to significantly lower production costs compared to hard rocks. However, the global distribution of lithium brine is geographically concentrated and dramatically uneven which may result in monopolies. Therefore, hard rock minerals should be used more effectively and economically to meet the increasing demand for lithium.

The largest concentrations of lithium-containing minerals are found in granitic pegmatites. The most important of these minerals are spodumene (Li₂O.Al₂O₃.4SiO₂), petalite (Li₂O.Al₂O₃.8SiO₂) and lepidolite (LiKAl₂F₂Si₃O₉ or LiF·KF·Al₂O₃·3SiO₂). Among these minerals, spodumene is considered the most important commercial lithium mineral due to its higher content.
