ABOUT THE DAGGETT LITHIUM PROJECT

The Property is comprised of 96 staked BLM and San Bernardino County registered lode mining claims (the "Lakshmi Claims") covering 2,641 acres (761 hectares). The Lakshmi Claims encompass a 9km strike length of exposed Barstow Formation clay-rich sediments containing anomalous levels of lithium.

The Barstow area, located in the central Mojave Desert hosts numerous historic and current mines and exploration projects. To the east of the Daggett Lithium Project, the now-inactive Hector Borate Mine was most recently operated by N.L. Industries Corp. ) ("N.L."). N.L. and its predecessors produced hectorite, a lithium-magnesium smectite clay for use in specialty applications. Currently, adjacent to that site, 5E Advanced Materials, Inc. is finalizing permitting while commissioning a new borate solution mining and refining operation.

Borates play a big part in the history of mining in the Barstow region, with commercial borate mining and refining operations dating from the 1880's in the nearby Calico Mountains, and even a small borate mining operation within the Lakshmi claims group. The Calico borate mines were active until the 1920's, at which time the Pacific Coast Borax Company commenced operations at their giant sodium borate deposit at Boron, California. Another active project in the area includes the Waterloo Mine Silver Project, currently operated by Apollo Silver Corp.

With its close association with borate mineralization and proximity to the Hector Mine, the Daggett Project is similar in occurrence to projects in advanced development in a similar geologic and tectonic setting in Nevada. The Project is well located in regard to infrastructure being within a very short distance from major highway, rail and energy corridors. It is also lies in close proximity to the town of Barstow, CA with available accommodations and labor.

IMEx Consultants Inc. ("IMEx"), the vendor of the Daggett Lithium Project, first sampled the project area in March of 2022. Based on past experience in the area exploring for borate minerals, IMEx was aware that the fine-grained sediments of the area contain anomalous levels of both boron and lithium. IMEx prospected the favorable sediments using a SciApps hand-help spectrometer (LIBS) to detect lithium contents of as much as 1,995ppmLi. Duplicate samples were submitted to the SGS laboratory in Lima, Peru and confirmed anomalous Li levels.
