Ameriwest Lithium Acquires Additional Seismic Data with the View to Drill Railroad Valley in 2022

VANCOUVER, March 28, 2022 - Ameriwest Lithium Inc. ("Ameriwest" or the "Company") (CSE: AWLI) (OTC: AWLIF) (FSE: 5HV0), a North American lithium exploration and development company, is pleased to announce the acquisition of a further 57 line-miles of high-quality seismic data from Seismic Exchange Inc. ("SEI"). The acquisition brings the total line-miles of data purchased to date from SEI to 83.7 line-miles. The additional data is being acquired to cover the Company's recently expanded 15,300-acre Railroad Valley property ("Railroad Valley" or the "Property") in Nye County, Nevada which Ameriwest believes hosts a large lithium brine exploration target.

On January 7, 2022, Ameriwest announced results from the interpretation of an initial 26.7 line-miles of historic seismic data acquired from SEI and initial Magnetotelluric ("MT") data acquired from Zonge International Inc. The results of this analysis, completed by Castillo Geophysical Inc. and Legg Geophysical Inc., exceeded expectations showing a potential brine reservoir at a depth of approximately 2,000 ft to 4,000 ft below surface at Railroad Valley. On February 16, 2022, the Company announced the results of a gravity survey completed by Tom Carpenter, consulting geophysicist, and expansion of the Railroad Valley to the north with the acquisition of 224 mineral claims from American Battery Technology Company ("ABTC"). Ameriwest announces it has staked 94 additional claims at Railroad Valley, bringing the total size of the Property to about 15,300 acres.

On March 10, 2022, Ameriwest announced the results from four MT lines completed by Zonge at Railroad Valley and plans to complete an additional two MT lines to the north. Ameriwest announces it has received the results from these two additional lines which show the brine target extending further to the north onto the claims acquired from ABTC. Ameriwest is proposing to complete an additional two MT lines farther to the north to further delineate and characterize the brine target.

The expansion of the Railroad Valley Property and the brine target contained therein has resulted in the Company acquiring another 57 line-miles of historic seismic data from SEI. Ameriwest's short term plan is to combine the data from the acquired seismic lines, the previous and proposed MT lines, the gravity survey, along with public information from historic oil and gas well drilling in the area of the Property to complete a three dimensional (3-D) geologic model of basin and the brine target. The goal is to establish an initial drill target to test the brine on the Railroad Valley Property for potential lithium content. Once the drill target is identified, the Company plans to move forward with permitting the drill program at Railroad Valley and the Company is actively pursuing prospective drilling companies in anticipation of drilling the Property in 2022.

Ameriwest has retained Castillo Geophysical Limited and Legg Geophysical, Inc. to complete the additional geophysical analysis. They regularly partner their combined experience at reprocessing vintage seismic data using modern processing techniques. Castillo Geophysical will reprocess the data while Legg Geophysical produces synthetics from existing well logs and interprets the data, incorporating related geophysical and geologic information to characterize the geometry of the basin. Their work is expected to be completed within the next 30-60 days.

David Watkinson, President and CEO of Ameriwest stated, "The Company has been able to take advantage of historic drilling and seismic geophysical data from the oil and gas industry available at Railroad Valley. We are combining this data with gravity and MT geophysical data to be able to develop a 3-D model of the basin and the brine target. The model allows us to interpret the shape, size, and location of the basin and brine target within, prior to drilling. It allows us to identify potential faults and structures in the basin, lithologic units, and other features. The MT data may allow us to predict where the highest-grade brine is located, based on resistivity. It will allow us to determine the best location possible to locate a discovery hole and determine what depth to drill."
