US Critical Metals Corp. and US Critical Materials Corp. to report the results for a geophysics survey completed over the Sheep Creek Rare Earth Project in southwestern Montana (?Sheep Creek?

or the ?Project?). The airborne geophysics survey was completed by Precision GeoSurveys Inc. (?Precision?). Project sample results demonstrate the potential for elevated grades of rare earth mineralization.

In combination with these geophysics results, Sheep Creek now has the potential for both grade and tonnage. Recent sample results include Sample #21112 at 201,216ppm (20.1%) Total Rare Earth Elements (?TREE?), containing 28,330ppm (2.8%) combined neodymium and praseodymium (?Nd+Pr?) and 363ppm Gallium (?Ga?), and Sample #21099 at 182,255ppm (18.2%) TREE, containing 32,750ppm (3.3%) combined Nd+Pr and 348ppm Ga. Geophysics suggests structural continuity along strike and possibly to depth in new geophysical exploration targets that could possibly host additional carbonatite bodies.

Concentration of carbonatite bodies suggests the possibility of additional undiscovered zones. The geophysical survey identifies seven locations warranting further exploration. Carbonatites contain few magnetic minerals compared to host rocks and could show as negative anomalies in magnetic studies.

Supports case for focused drill program to test structures identified at surface, present in the historic underground workings, and possible deeper geophysical targets identified in the survey. The survey covered approximately 8 kilometers by 7.45 kilometers in size, which represents a total area of approximately 59.5 square kilometers. The survey was flown with 100 meter line spacing on the survey lines at a heading of 044°/224°, and with 1,000 meter line spacing on the tie lines at a heading of 134°/314°.

A total of 658 line kilometers of high resolution magnetic and radiometric data were collected by helicopter. The survey was designed with the objective of identifying targets that correspond to a pattern and delineate geological structure as it relates to the magnetic and radiometric data. To accomplish these objectives, Precision took the following steps: Gridded and plotted magnetic data, radiometric data, and topography onto maps in Geosoft.

Identified correlations in geology between potential target areas by utilizing historical geologic information. Identified zones with similar magnetic signature, orientation, and geologic setting. The interpretation of the subsurface structure was performed using the following procedure: The vertical magnetic gradient (CVG) and the horizontal magnetic gradient (CHG) were calculated from the reduced to magnetic pole (RTP).

Preliminary structures were identified based on the RTP and the derivative data (CVG & CHG). An upward continuation filter and a downward continuation filter were performed on the RTP data. Interpretation of structure and features were compared to the various grids produced by the different data processing steps.

Radiometric data were overlain to compare and determine any correlation.
