Public information sessions planned to share progress ahead of environmental assessment registration

St. John's, Newfoundland--(Newsfile Corp. - March 4, 2026) - Triple Point Resources Ltd. ("Triple Point" or the "Company") provides an update on feasibility work for its Fischells Salt Dome project (the "Project"), a proposed long-duration energy storage facility at the Fischells salt dome in western Newfoundland and Labrador.

Following the Company's appointment of WSP to lead feasibility work, Triple Point confirms that WSP has delivered key feasibility components including the solution-mining assessments, initial development pathways for salt/brine management and salt commercialization, and an investment-supporting business case. WSP's work advanced the Project's engineering design along with engineering opportunities and recommendations to guide next steps.

In parallel, Triple Point is working with its technology partner, Siemens Energy to advance the compressed air energy storage ("CAES") power system and grid integration workstream, which is expected to be completed in April 2026.

"This phase advances our technical and economic options for compressed air energy storage with value added salt commercialization potential revenue at the Fischells Salt Dome," said Julie Lemieux, CEO of Triple Point Resources. "With the geology already proven, we have focused on aligning engineering design, economics and local input to move the project forward. We are ready to share what we have learned and continue refining the project with communities."

The Project is being evaluated as a long-duration energy storage facility that will support the Newfoundland grid. Services under assessment include firm capacity to support the retirement of aging thermal generation, improved grid reliability, reduced renewable curtailment, and greater system flexibility as wind resources expand.

Public information sessions - March 2026

Triple Point will host public information sessions in March 2026 to present a project overview and update, and its plans for environmental assessment registration in early April 2026. Attendees will be able to ask questions and provide input as planning continues.

Community information sessions will be held at:

• St. Georges, March 24 at 6:00 p.m., Parish Hall
• McKays, March 25 at 6:00 p.m., Lions Club
• Flat Bay, March 26 at 6:00 p.m., Peoples Complex

"The work completed so far gives us confidence in the project's technical foundation," added Lemieux. "We look forward to continuing the conversation and advancing this project in collaboration with communities."
