(via TheNewswire)

VANCOUVER, BC –  TheNewswire - April 30, 2026 - One World Lithium Inc. (CSE-OWLI) (the “Company” or “OWL”) is pleased to announce that they have now engaged with Moleaer Inc. (“ Moleaer ”) the global leader in nanobubble technology, and two strategic University, Research and Development Laboratories (“R&D”) to accelerate testing of its patent-pending, proprietary, single-step Direct Lithium Carbonation Extraction (“ DLCE” ) technology. This collaboration aims to finalize a containerized, shipping-container-sized pilot plant designed to produce lithium carbonate directly from natural brines, eliminating costly and environmentally intensive traditional concentration methods.

About Moleaer Inc.

Moleaer will work directly with OWL and the two R&D laboratories to advance the Company’s DCLE technology through continued laboratory testing and engineering evaluation towards  a pilot plant and commercialization.

Moleaer has deployed thousands of nanobubble solutions worldwide to improve process performance across water and wastewater treatment, agriculture, mineral recovery, and more. Its platform enables efficient and stable gas delivery in liquids, helping operators achieve more consistent and reliable outcomes. The Company has one of the largest dedicated R&D teams focused on studying nanobubbles, advancing the science and translating it into practical, field-proven applications. Moleaer routinely seeks partnerships with innovators across a broad spectrum of industries to integrate its proprietary nanobubble solutions into partner technologies to enhance traditional applications and systems.

Primary Project Goals - Advancing Toward Pilot-Scale Development

The first phase of the laboratory work is focused on continued validation and optimization of the DLCE process, which uses a nanobubble extraction process using carbon dioxide to separate lithium   from brines  with the objective of advancing toward the design and construction of a pilot plant for field testing. The pilot system is intended to demonstrate the potential for direct production of lithium carbonate from natural brines.

The second phase of the laboratory work is to complete test work on lithium clay samples to create an effective lithium slurry to validate the DLCE technology to produce a lithium carbonate from the slurry under a variety of conditions. This process would enable lithium carbonate generation directly from slurries made from clays, without requiring sulfuric acids, soda ash, sorbents, and multiple concentration steps.

Doug Fulcher, President and Chief Executive Officer of One World Lithium, states :

“This is a major step forward for the Company as we bring together key technical partners to advance DLCE from ongoing laboratory testing toward pilot-scale validation and potential commercialization. Working with a leader in nanobubble technology strengthens our ability to evaluate and optimize the process across a range of natural brines and clay-based feedstock, which we believe may be critical to further validating the technology.”

Brad Hice, Senior Director – Market Development at Moleaer Inc., states:

 “We believe this approach to lithium extraction from brines has the potential to significantly improve how lithium is produced. Moleaer is pleased to support the One World Lithium’s efforts across technology development, process optimization, and potential commercialization pathways.”

The proposed approach is designed to minimize or eliminate the use of sorbents, sulfuric acids, and soda ash, and fresh water with the goal of simplifying the overall flowsheet and potentially reducing both capital and operating costs compared to conventional lithium production methods.

Evaluation of By-Product Recovery

In parallel with lithium carbonate production, the Company is also evaluating the potential recovery or co-production of additional industrial carbonates from brine, including sodium, calcium, magnesium and potassium. These materials, if successfully recovered at scale, could represent incremental revenue streams and improve overall project economics.

Process Advantages Under Evaluation

The DLCE process is being developed as a simplified extraction pathway that does not require pre-concentration, base concentration, or post-concentration steps commonly associated with conventional evaporation pond operations and certain direct lithium extraction (“DLE”) technologies.

Unlike traditional methods that typically produce lithium intermediates requiring additional downstream chemical processing to generate lithium carbonate, the Company’s objective is to produce lithium carbonate directly in a single-step process.

Carbon Utilization and Environmental Considerations

DLCE approach targets a simplified, lower‑ impact extraction pathway that removes several steps common to evaporation ponds and many DLE processes. By integrating carbon dioxide in the separation chemistry and minimizing chemical inputs and concentration stages, OWL expects, subject to further testing, reduced environmental impacts, lower capital and operating costs, and potential carbon credit opportunities pending pilot validation.

Next Steps

Results from the ongoing laboratory program will be used to refine process parameters, support engineering design work, and advance the development of a containerized pilot plant for subsequent field testing.

Funding for the Test Work

The Company also announces a non-brokered private placement up to 20,000,000 units (each, a “ Unit ”) of the Company at a price of $0.04 per Unit, for gross proceeds of up to $800,000 with (the “ Offering ”). All amounts are stated in Canadian dollars.

Each Unit will consist of one common share (each, a “ Common Share ”) of the Company and one non-transferable Common Share purchase warrant (each, a “ Warrant ”). Each Warrant will entitle the holder thereof to purchase one additional Common Share (each, a “ Warrant Share ”) at a price of $0.08 per Warrant Share for a period of 36 months from the closing of the Offering.

There is no minimum number of Units or minimum aggregate proceeds required to close the Offering, and the Company may, subject to compliance with applicable securities laws, elect to close the Offering in one or more closings.

Management anticipates that the Company will allocate the net proceeds of the Offering for working capital purposes and for advancing its patent ‑ pending DLCE technology, including continued laboratory testing, engineering evaluation and related general and administrative expenditures. No portion of the proceeds will be used for investor relations or promotional activities.

Finder’s fees may be payable in connection with the Offering in cash and/or securities, in each case in accordance with applicable securities laws and the policies of the Canadian Securities Exchange (the “ CSE ”). Closing of the Offering is subject to the receipt of all required corporate and regulatory approvals, including approval of the pricing of the Offering by the CSE.

All securities issued in connection with the Offering will be subject to a statutory hold period of four months plus one day from the date of issuance, in accordance with applicable securities laws.
