One World Lithium Announces DDH-3 Drilling Program Has Started at its Salar Del Diablo Lithium-Brine Project

The drilling date was previously announced to be April 15, 2021, however the San Felipe Baja 250 desert race took place from April 14 to 18, 2021 which crossed the DDH-3 location for five days, so the drilling program was delayed.

Some of the following information has been previously reported in the Company's news released on March 16 and April 06, 2021. DDH-3 (diamond drill hole) is 50 kilometers south of DDH-2 and depending on results, OWL may drill more diamond drill holes in the immediate area.

Mike Rosko, the Operator, prefers drilling at DDH-3's location as there is historic and current hydrothermal activity that are evident and is often a source of lithium, such as in the Lithium Triangle in Argentina and Chile. The surface area of the hydrothermal activity at the DDH-3 location is approximately 20,000 hectares or 77 square miles.

DDH-3's total depth to sample brines or sediments where hydrothermal activity may have occurred which is likely between 300 and 400 meters. There has not been any previous drilling at the south end of the Property, so the expected time to reach the total depth at the DDH-3 location is unknown.

The Salar del Diablo Property is 103,450 hectares (399 square miles) and located in the State of Baja California, Mexico. Globally, the Salar del Diablo is one of the larger Salars to be drilled in 2021.

OWL currently owns a 60% property working interest. The three or more drill holes are part of the Phase three program and on completion, OWL will then own an 80% property working interest with a onetime option on receiving a Bankable Feasibility Study to purchase an additional 10% property working interest for a total property working interest of 90 %. For more information on Salar del Diablo property and the terms of the Company's option thereon, please see the Company's press release dated March 10, 2017, and July 28, 2017.

The States of Sonora and Baja California in Mexico have deemed mineral exploration an essential service with no disruptions to date caused by Covid-19.

All drill hole samples from the current three or more holes will be assayed at ALS labs with an expected turnaround time of two to three weeks. After interpretation, the assay results will be released.
