Global Battery Metals Ltd. (TSXV: GBML) (OTCQB: REZZF) (FSE: REZ) (the "Company" or "GBML") is pleased provide an update on its Lithium King property (the "Lithium King Property") in Utah.

Lithium King Property Update:

• The Company has renewed leases on 88 claims covering a total area of 1,760 acres.
• The claims cover geologically significant features such as basement high and local graben fault structures believed to allow up-flow of lithium bearing fluids from deeper basinal brines.
• Early exploration was conducted by covering the claim area with ground magnetic and gravity surveys.
• Work completed since project acquisition in March 2021 has identified ideal locations for initial well test drill holes.
• McKay Mineral Exploration, LLC has been hired to assist in the drill permit application.

Michael Murphy, President and CEO, commented "Our work to date on the Lithium King property continues to support our thesis of the potential for the discovery of a significant lithium bearing brine aquifer. Our work will focus on a key fault structure that is interpreted to allow up-flow of lithium bearing fluids. With the engagement of McKay Minerals Exploration, LLC, we look forward obtaining a drill permit before year end."

Summary of Work Completed on the Lithium King Property

The Lithium King property was identified by the Company in 2020 and the project area was staked in the first quarter of 2021.

Historical Lithium values from 39 shallow USGS wells (25 feet) averaged 244 parts per million (ppm) and ranged from a low 49 ppm to a high of 1,200 ppm. The Lithium King property is within the Great Basin of the Western United States, where lithium concentrations of greater than 10 ppm in brines are anomalous. Lithium values from the only lithium production in the United States, in Clayton Valley, Nevada, also in the Great Basin, range from 75 to about 250 ppm.

Magnesium values at the property and near vicinity range between 1,300 and 8,500 ppm.

The shallow aquifer water samples may not reflect the deeper basin below 25 feet depth. Drilling to bedrock and brine sampling is needed to confirm the presence of and concentration of lithium in the deeper basin brines.

Based on the geophysical surveys and historical data, the area underlying the claims are interpreted to be part of a regional basement high with local graben structures. This structural setting is believed to represent a conduit for basinal brine up-flow.

Earlier this year, 32-line km, over four lines, of ground magnetic was acquired over the claim package and basement/basin boundary. The same lines were then surveyed using ground gravity. The work was done by Quantec, and the results were inverted in 2D sections to help with basin interpretation and test well targeting.

Based on this work, four initial test well targets have been identified within the claim block.

Lithium King Property Description

The Lithium King Property is located on the west side of the Great Salt Lake Basin in western Utah, adjacent to the community of Wendover, Utah. The land position consists of approximately 1,760 acres of placer claims. The property has the potential to host a lithium and magnesium brine deposit in an existing mineral producing location in a mining-friendly state (see Company news release from March 4, 2021 for detailed project review).

Cautionary Statement Regarding "Forward-Looking" Information

This press release contains certain "forward-looking statements" within the meaning of Canadian securities legislation, relating to a drill program to be conducted on the Company's North-West Leinster lithium property in Ireland. Although the Company believes that such statements are reasonable, it can give no assurance that such expectations will prove to be correct. Forward-looking statements are statements that are not historical facts; they are generally, but not always, identified by the words "expects," "plans," "anticipates," "believes," "intends," "estimates," "projects," "aims," "potential," "goal," "objective," "prospective," and similar expressions, or that events or conditions "will," "would," "may," "can," "could" or "should" occur, or are those statements, which, by their nature, refer to future events.
