ONE WORLD LITHIUM ANNOUNCES DELISTING FROM OTCQB

VANCOUVER, BC - September 30, 2025- One World Lithium Inc. (CSE-OWLI) (OTCQB-OWRDF) (the "Company" or "OWL") announces that it will delist its shares from the US OTCQB to the Pink Limited equity market effective October 01, 2025.

of the Company have determined that the costs associated with a dual listing are not warranted

at this time and that savings from this decision will go to support the companies ongoing working capital and research and development needs. This decision does not preclude the Company from re-listing its shares on the OTCQB at a later date.
