USCM Intercepts Host Rocks Favorable for Lithium Mineralization in Initial Phase of Drilling at Clayton Ridge

Vancouver, September 12, 2023 - US Critical Metals Corp. (CSE: USCM) (OTCQB: USCMF) (FSE: 0IU0) ("USCM" or the "Company") is pleased to announce that it has completed the first phase of drilling at the Clayton Ridge Lithium Property ("Clayton Ridge" or the "Project") located in Esmeralda County, Nevada. Clayton Ridge is located on the eastern flank of the Clayton Valley, the only lithium producing region of the United States.

The Company has completed approximately 1,000 meters of core drilling into the south and central zones of Clayton Ridge. The core has been cut, logged and will be sent to American Assay Labs for assaying. The initial phase of the program consisted of 11 holes and was completed by Falcon Drilling, Inc. ("Falcon Drilling"). The holes were drilled based on sampling from surface outcrops and mapping carried out by the Company. To date, 315 rock chip samples have been collected within the Project area. Each hole was drilled from surface to basement floor. All holes were drilled from individual drill pads. The figures below summarize the drill holes and locations.

The initial program utilized the permitted disturbance area of up to 5 acres as previously approved by the Bureau of Land Management ("BLM"). The Company is currently reclaiming a portion of these lands with the objective of accessing the northern unit of the Property (drill sites L-P). Documents have been submitted to the BLM and upon anticipated approval, the Company intends to mobilize the drill rig to further test the northern section of the Project.

USCM has the right to earn a 100% interest in the Project subject to completing the following, expected to be completed in 2023: (i) drilling 1,500 meters on the Project, (ii) paying US$75,000 in cash to the property vendors; and (iii) issuing 500,000 common shares of the Company to the property vendor. Upon completion of the foregoing conditions, USCM will acquire a 100% interest in Clayton Ridge.

Management Commentary

Mr. Darren Collins, Chief Executive Officer and Director of USCM, comments: "We are very pleased to complete this initial phase of our two-phase program and encouraged by the potential widths and grades of Clayton Ridge. Completion of the program will position USCM with two wholly-owned assets and demonstrates our strategy to source attractive assets within the US and fulfill earn-in terms by funding meaningful technical work. We look forward to providing further details once assay results are available."

Project Overview

The Project is a lithium claystone deposit located in Esmeralda County, Nevada on the east flank of the Clayton Valley, the only lithium producing region of the United States. The Property is located just 18 kilometers west of Goldfield, Nevada and roughly 17 km southeast of Silver Peak, Nevada, lying within a topographic swale between the Montezuma Range and Clayton Ridge. The project is comprised of 180 unpatented lode mining claims, covering 3,600 acres, with easy driving access to all claims. The Property is one of several lithium projects in region. In addition to the only operating lithium producer in the US (Albemarle), the Clayton Valley and immediate surroundings host several lithium projects ranging from early- to late-stage exploration (including, but not limited to, Noram Lithium, Pure Energy, American Lithium, Ioneer Ltd., Century Lithium Corp. and Spearmint Resources).

About US Critical Metals Corp.

USCM is focused on mining projects that will further secure the US supply of critical metals and rare earth elements, which are essential to fueling the new age economy. Pursuant to option agreements with private Canadian and American companies, USCM's assets consist of four agreements, together providing USCM with the right to acquire interests in five discovery focused projects in the US. These projects include the Clayton Ridge Lithium Project located in Nevada, the Sheep Creek Rare Earth Project located in Montana, the Haynes Cobalt Project located in Idaho, the Lemhi Pass Rare Earth Project located in Idaho and the Long Canyon Uranium Project located in Idaho. A significant percentage of the world's critical metal and rare earth supply comes from nations with interests that are contrary to those of the US.
