One World Lithium Inc. (the ‘Company' or ‘OWL') announced that on December 31, 2021, it received Montgomery and Associates Consultores Limitada (‘M&A') Report for the Company's 2019 and 2021 four-hole exploration diamond drilling program that was conducted at its Salar del Diablo Exploration Project located in the State of Baja California, Mexico. During 2019, DDH (diamond drill hole) 19-01 reached a total depth of 647 meters. Eighteen groundwater samples were taken at depths of 235 meters, 301 meters, 463 meters, 506 meters and 633 meters and one sample was analysed from each depth.

During 2019, DDH-19-02 reached a total depth of 595 meters two groundwater samples were obtained at a depth of 431 meters; one of these was submitted for laboratory analysis. During 2021, DDH 21-01 reached a total depth of 191 meters but was abandoned as it became unstable. Three groundwater samples were taken at a depth of 183.2 meters and one sample was analysed.

During 2021, DDH-21-04 was drilled to a total depth of 518 meters with four groundwater samples taken at depths of 331 meters and 460 meters and one sample from each depth was analysed. Based on the results of chemical analysis for all of the depth-specific samples for each of the four exploration boreholes, it is concluded the basin consists of fresh water and less than 5 ppm (parts per million) lithium. Drilling conditions were challenging as the fine grained and poorly consolidated nature of sediments that were only poorly to moderately cemented resulted in abundant borehole unravelling and ‘caving' during drilling.

In addition, the Ejidos, or local surface rights owners, threatened to blockade the access road to DDH 21-01. As a result, the Company decided to abandon this location and relocate drilling to 16 kilometers to the north that is the location for DDH 21-04. In accordance with a request from the Company, M&A was contracted to oversee and act as the Qualified Person, as defined in National Instrument 43-101, to document the results from the late-2019 and 2021 exploration program in Salar del Diablo, near the town of San Felipe in Baja California, Mexico.

Drilling and sampling of two exploration boreholes occurred during October through December 2019 in the north part of the OWL exploration concessions, and two occurred during May and October of 2021 in the south part of the OWL concessions. All drilling was done by Layne de Mexico, Hermosillo, Mexico. M&A field hydrogeologists were onsite during the period from October 20th to November 8th of 2019, from April 28th to May 19th of 2021, and from September 30th to October 9th of 2021, to coordinate field activities regarding drilling, core characterization, packer sampling methods and protocols, and to select specific depths for groundwater sampling.

One of the objectives for this project was to collect groundwater samples at specific depths using inflatable packers that are able to isolate specific zones of the aquifer where samples could be obtained and attributed to that specific part of the aquifer. During year 2019, 18 groundwater samples were obtained from borehole SDDDH19-01, at depths of 235 m, 301.6 m, 463.3 m, 506 m, and 633 m. A single sample from each depth was submitted for laboratory analysis. Two samples were obtained at borehole SD-DDHTC19-02 at a depth of 431 m; one of these was submitted for laboratory analysis.

During year 2021, three groundwater samples were collected from borehole SD-DDH21-01, at a depth of 183.2 m; one of these was submitted for laboratory analysis. A total of four samples were collected at borehole SD-DDH21-04 at depths of 331 and 460 m; one sample from each depth was submitted for laboratory analysis. During both the 2019 and 2021 campaigns, groundwater samples were obtained and submitted to ALS Laboratories' Hermosillo office, and then subsequently sent to their lab in Vancouver, British Columbia, Canada for analyses.

Samples were analyzed for common constituents and trace metals, including barium, boron, calcium lithium, magnesium, potassium and sodium. In addition, field parameters of groundwater samples were measured by OWL and M&A field personnel. Field measurements included pH, Resistivity, ORP, Electrical Conductivity, and Temperature; a Myron-L 6P meter was used to measure these parameters.

Density of the groundwater was measured using a hydrometer. All samples were kept in San Felipe under the supervision of the Company's Project Manager, and subsequently transferred by truck from San Felipe to Hermosillo. In Hermosillo, the samples were delivered by the Qualified Person to ALS Global's laboratory for preparation and shipping to Vancouver for analysis.
