Accounting Policies [Abstract]
Basis of Presentation	2. Basis of Presentation Basis of Presentation and Principles of Consolidation The Company’s consolidated financial statements have been prepared in accordance with the accounting principles generally accepted in the United States of America (“GAAP”) on a going concern basis, which contemplates the realization of assets and the discharge of liabilities in the normal course of business for the foreseeable future. The consolidated financial statements include the results of the Company and its subsidiaries. A subsidiary is consolidated from the date upon which control is acquired by the Company and all intercompany transactions and balances have been eliminated. Certain prior period amounts in the consolidated financial statements and accompanying notes have been reclassified to conform to the current period’s presentation. Functional Currency The Company has determined that the U.S. dollar is the functional currency for all the Company’s operations since the Company conducts the significant majority of its operations through its U.S subsidiary, IBAT USA, Inc., compensates all of it corporate officers and the board of directors in U.S. dollars and historically the majority of its expenditures are also denominated in U.S. dollars. The Company has maintained limited amounts of Canadian dollars to cover administration expenses associated with the Company’s registration in Canada. For the year ended March 31, 2026, and 2025, the Company recognized net transaction losses of approximately $13,000, and $38,000, respectively, related to currency exchange rates. Liquidity and Capital Resources As of March 31, 2026, the Company had an accumulated deficit of approximately $39.4 million and a working capital of approximately $9.2 million. During the year ended March 31, 2026, the Company raised cash in four private placements totaling $9.0 million with EV Metals 7 LLC,EV Metals VI LLC, and EV Metals 9 LLC ("2025 EV Metals Letter Agreement"). Our Initial MDLE Plant was constructed with twelve absorption columns, which form the core of the direct lithium extraction process. In operation, brine flows continuously through these columns, where lithium and chloride ions are selectively captured utilizing IBAT's proprietary media located inside the absorption columns and subsequently eluted to produce a concentrated lithium chloride solution. Our Initial MDLE Plant was designed for a specific deployment in the Lithium Triangle in South America which had lithium concentrations of roughly 1,800 ppm and therefore required lower flow rates, of approximately 300 gallons per minute of brine, to efficiently recover lithium. However, the Initial MDLE Plant is designed to be scalable and commercially flexible and was engineered to permit retrofitting to process a range of alternative brine resources of different lithium concentrations. We are currently targeting deploying our Initial MDLE Plant at naturally occurring brine reservoirs in the United States, or internationally, which have brine concentrations in the range of 250 ppm to as high as 800 ppm, although brine concentrations in the Smackover play in Texas and Arkansas are generally estimated to be between 200 and 400 ppm based on publicly published recent brine resource lithium concentrations by a number of resource owners. At 400 ppm, the Initial MDLE Plant can operate at approximately 200 gallons per minute, resulting in output of between 600 and 700 metric tons per year of lithium chloride, on a lithium carbonate equivalent basis. Based on ongoing discussions with potential customers and their requirements based on their specific brine concentrations, we have evaluated various customizations that we could implement to increase flow rate and expand the Initial MDLE Plant’s capacity. For example, management has designed a case to optimize the flowrate to fully utilize the twelve-column absorption capacity by adding components such as additional heat exchangers, pumps, condensate coolers, a reverse osmosis unit, chillers, tanks and pipelines. We estimate that the optimized Initial MDLE Plant could increase throughput to approximately 480 gallons per minute, which based on a 400 ppm brine stream, we believe would be capable of producing approximately 2,000 metric tons per year of lithium chloride, on a lithium carbonate equivalent basis. Depending on the level of customization required, we anticipate that we could incur approximately between $2.0 million to $12.0 million of additional capital expenditures in connection with the deployment of the Initial MDLE Plant at a customer’s brine reservoir site. The low-end of this estimate is based on “make-ready expenditures” to adapt the Initial MDLE Plant to the customer’s location and retain the 600 to 700 metric tons per year capacity, while the high-end represents implementing a full range of customizations to upgrade the MDLE Plant to approximately 2,000 metric tons per year capacity of lithium chloride output, on a lithium carbonate equivalent basis. The cash we have on hand as of March 31, 2026 will not be sufficient to fund the high end of these expenditures. We will have to raise additional funds from current or new investors to fund the modifications to the Initial MDLE Plant to allow us to fully recover the current amounts capitalized on our balance sheet. On July 20, 2025, the Company entered into binding subscription agreements (“Encompass Subscription Agreements”) with Encompass Capital Advisors LLC ("Encompass"), acting for certain fund entities and managed accounts for which Encompass exercises investment discretion, for the purchase of up to 25,765,259 units (the “2025 Encompass Units”) at a price of CAD$0.26625 per unit (USD$0.19406 per unit) for gross proceeds of $5.0 million to the Company (the “2025 Encompass Offering”). Each 2025 Encompass Unit consists of one Common Share and one warrant, with each warrant entitling the holder to purchase one additional Common Share for a period of three years from the closing date of the 2025 Encompass Offering at an exercise price of CAD$0.355 per share. In addition, the Company has agreed to grant Encompass the right but not the obligation, to purchase up to $2.0 million of additional units of the Company, at any time on or before March 31, 2026. Encompass did not exercise its right to purchase any additional units of the Company prior to March 31, 2026. The 2025 Encompass Offering closed on August 5, 2025. While the cash from the private placements is anticipated to support the Company’s operations, the Company continues to incur operating losses and negative cash flows. The Company has historically relied on raising funds through private placements of the Company’s common units and warrants and there is no assurance that the Company will be able to do so in the future or raise such funds at terms acceptable to the Company. Without additional funds, management believes there would be substantial doubt about the Company’s ability to meet its obligations as they come due over the next twelve months from the issuance date of the financial statements. However, with the working capital the Company has on hand and the proceeds from the private placement with EV Metals, which were received on April 29, 2026 (see Note 18), provide the Company with sufficient funds to meet its obligations as they become due within one year from the date that these consolidated financial statements are issued.
