Grounded Lithium Reports Third Quarter 2025 Financial Results and Project Update

CALGARY, AB, Nov. 12, 2025 /PRNewswire/ - (TSXV: GRD) (OTCQB: GRDAF) - Grounded Lithium Corp. ("GLC" or the "Company") announces our financial and operating results for the three and nine month periods ended September 30, 2025.  Selected financial and operational information is set out below and should be read in conjunction with the Company's December 31, 2024 financial statements and the related management's discussion and analysis, which are available for review at www.sedarplus.ca or the Company's website at www.groundedlithium.com.

Kindersley Lithium Project ("KLP") Update

GLC, in partnership with our partner, Denison Mines Corp ("Denison"), continues to progress the various technical studies necessary for the completion of the pre-feasibility study ("PFS").   Areas of focus include extensive engineering analysis in cost minimization for lithium extraction from the brine to produce a final lithium hydroxide or lithium carbonate product and secondly, how best to optimize depletion of lithium from the lithium-rich brines in the Duperow Formation.  Denison's experience with in-situ uranium extraction provides a specialized expertise in extracting valuable elements from brines or acids. 

Our brine was shipped to three different direct lithium extraction ("DLE") labs together with the federal government's Canmet research facility in Ottawa.  The lead author for the PFS, Stantec, will reflect the current understanding from lab results to determine the optimal technology for extracting lithium from the brine.  Technology companies continue to progress their DLE technologies through both field and lab work on a cost advantaged basis.  GLC and Denison officials will monitor and evaluate those efforts for possible future implementation in field pilots and commercial production for the KLP.  

The recently completed depletion study determined an optimized field configuration into the reservoir to maximize lithium recovery, minimizing costs and equally minimizing the environmental footprint through comprehensive three-dimensional reservoir modelling. This work benefitted from prior modelling efforts and field work conducted in 2022 and 2024 which gave valuable insights into the lithium prone reservoir within the Duperow zone. The current optimized plan includes the positioning of three to four production wells on each surface lease, drilled on an angle in orthogonal directions to maximize separation and exposure to the Duperow reservoir.  Each of the four wells maximizes reservoir productivity with two additional horizontal and parallel legs of 700 meters each drilled within the two separate layers identified as the best for porosity and deliverability.   This multi-well pad configuration is designed to reduce costs and footprint by minimizing pipeline infrastructure and optimizing well services while maximizing deliverability over an extended period of time. The PFS scheduled to be completed in the first half of 2026.

Forward-Looking Statements

This press release may contain forward-looking statements and forward-looking information within the meaning of applicable Canadian securities laws. The opinions, forecasts, projections and statements about future events of results, are forward looking information, forward-looking statements or financial outlooks (collectively, "forward-looking statements") under the meaning of applicable Canadian securities laws. These statements are made as of the date of this press release and the fact that this press release remains available does not constitute a representation by GLC that the Company believes these forward-looking statements continue to be true as of any subsequent date. Although GLC believes that the assumptions underlying, and expectations reflected in, these forward-looking statements are reasonable, it can give no assurance that these assumptions and expectations will prove to be correct. Such statements include, but are not limited to, statements regarding the internal rates of return and net present values of the KLP, activities funded by Denison to drive the KLP value and GLC's vision of becoming a best-in-class, environmentally responsible, Canadian lithium producer supporting the global energy transition.

Among the important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are: GLC's expectation that our operations will be in Western Canada, unexpected problems can arise due to technical difficulties and operational difficulties which impact the production, transport or sale of our products; geographic and weather conditions can impact production; the risk that current global economic and credit conditions may impact commodity prices and consumption more than GLC currently predicts; the failure to obtain financing on reasonable terms; volatility in the trading price of the common shares of the Company; the risk that unexpected delays and difficulties in developing currently owned properties may occur; the failure of drilling to result in commercial projects; unexpected delays due to the limited availability of drilling equipment and personnel; and the other risk factors detailed from time to time in GLC's periodic reports. GLC's forward-looking statements are expressly qualified in their entirety by this cautionary statement.

This news release shall not constitute an offer to sell or the solicitation of an offer to buy any securities in any jurisdiction.
