VANCOUVER, BC – August 28, 2026 – TheNewswire - One World Lithium Inc. (CSE-OWLI) (the “Company” or “OWL”) is pleased to announce that, further to its news release dated July 24, 2026, the Company has closed the first tranche of its previously announced $910,000 non‑brokered private placement (the “Offering”), issuing units (each, a “Unit”) of the Company for aggregate gross proceeds of $264,150 (the “First Tranche”).

In connection with the closing of the First Tranche, the Company issued an aggregate of 7,547,142 Units at a price of $0.035 per Unit. Each unit consisted of one common share (each, a “Share”) and one-half non-transferable share purchase warrant (each, a “Warrant”), with each Warrant being exercisable to purchase one additional Share at a price of $0.08 for 36 months from the date of issuance.

The Company intends to use the net proceeds of the Offering for advancing its patent‑pending lithium extraction technologies, including continued laboratory testing, engineering evaluation and working capital purposes.

An officer and director and another director of the Company participated in the First Tranche and, as such, their participation each constituted a related party transaction as defined under Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“ MI 61-101 ”). Such participation is exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 as neither the fair market value of the securities acquired by the insiders, nor the consideration for the securities paid by such insiders, exceeds 25 per cent of the Company’s market capitalization.

In addition to the applicable statutory hold period, securities issued pursuant to the Offering will be subject to an Exchange Hold for a period of four months from the date of issuance in accordance with the policies of the Canadian Stock Exchange.
