Appoints Dr. Peter Barry as Helium-3 Advisor

PULSAR HELIUM APPOINTS DR. PETER BARRY AS SCIENTIFIC HELIUM-3 ADVISOR

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) ("Pulsar" or the "Company"), a leading helium exploration and development company, is pleased to announce the appointment of Dr. Peter Barry of the Woods Hole Oceanographic Institution (WHOI) as the Company's Scientific Helium-3 Advisor. Dr. Barry, a noble gas isotope geochemist and Associate Scientist at WHOI, and specialist in crust-mantle interactions, will lead Pulsar's helium-3 research efforts as the Company advances its flagship Topaz helium project in Minnesota. In this role, Dr. Barry will spearhead Pulsar's helium-3 program, guide scientific strategy while ensuring rigorous data analysis of all geochemical datasets.

In his advisory role, Dr. Barry will:

• Interpret Noble Gas Data: Oversee the interpretation of noble gas isotopic data from Pulsar's helium wells, providing expert insights into helium-3 content and origin.
• Research Grant Development: Drive the development of proposals for research grants and partnerships, leveraging Pulsar's discoveries to attract funding and collaborative opportunities in helium-3 research.
• Collaborate with engineering team: Provide guidance on solutions for the viable retrieval, containment, and preservation of helium-3, supporting Pulsar's objective of product entry into the U.S. market.
• Barry will also coordinate the independent validation of helium-3 in Pulsar's gas samples. He will oversee the collection of gas samples from the Topaz Project's Jetstream #1 well, and potentially other wells, and coordinate with U.S. government laboratories to verify geochemical results. These institutions will conduct high-precision analyses to confirm the presence and isotopic composition of helium-3 in the samples, providing third-party verification of Pulsar's results. This initiative underscores Pulsar's commitment to the highest scientific standards as it evaluates the helium-3 potential of its discoveries and defines a pathway for helium-3 to become a viable, saleable commodity within the Topaz reservoir's proven suite of high-value gases.

Thomas Abraham-James, President & CEO of Pulsar, commented:

"We are thrilled to welcome Dr. Peter Barry as our Scientific Helium-3 Advisor. Dr. Barry's expertise in noble gas geochemistry and his deep understanding of helium systems will be invaluable as we advance the Topaz Project and our broader helium-3 initiatives. His leadership will ensure that our helium-3 analyses and reservoir models are conducted with rigorous scientific oversight, strengthening Pulsar's position at the forefront of terrestrial helium-3 exploration. This appointment underscores our commitment to unlocking the full potential of the Topaz discovery and maintaining Pulsar's lead in a field of growing strategic importance."

Strategic Importance of Helium-3

Helium-3 is one of the rarest and most valuable isotopes on Earth, with reported prices reaching up to US$18.7 million per kilogram, over 100,000 times the price of common helium (helium-4). Its scarcity and unique properties give it outsized strategic importance for both energy and scientific innovation. Recognizing its value, NASA and the U.S. government are actively funding efforts to extract helium-3 from lunar regolith. (The Moon's soil is estimated to contain on the order of 1.4-15 parts per billion of helium-3.) Against this backdrop, Pulsar's terrestrial helium-3 discovery at Topaz, with measured concentrations up to 14.5 parts per billion (ppb) in the Jetstream #1 well, is an extraordinary development. The levels identified at Topaz are comparable to those found in lunar samples, highlighting the world-class significance of Pulsar's find.

• Peter Barry's Geochemistry Expertise
• Peter Barry brings world-class scientific credentials to Pulsar's team. He is an Associate Scientist in the Marine Chemistry & Geochemistry department at WHOI, where he specializes in using noble gas and stable isotope geochemistry to study Earth's volatile elements and geological processes. A researcher at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts - accredited by the New England Commission of Higher Education - Dr Barry's work spans high-temperature geochemistry, crust-mantle interactions, and the behavior of gases and fluids in the Earth's lithosphere. Notably, Dr. Barry has extensively investigated the occurrence of helium in nature - recognized for his work helping explain the distribution of major helium gas reservoirs on Earth. He earned his Ph.D. in Earth Sciences from the Scripps Institution of Oceanography (UC San Diego) and has held research positions at the University of Tennessee and the University of Oxford.
• Barry is no stranger to Pulsar's projects. As a noble gas isotope expert, he has been consulting with the Company on the Topaz helium discovery since its early stages. He analyzed the full suite of gas samples from the Jetstream #1 well, which revealed helium concentrations up to 14.5% (by volume) in the raw gas, and provided key interpretations that a small amount of air contamination had likely made that helium reading a conservative estimate. His guidance has been instrumental in characterizing the Topaz find, and in his formal capacity as Scientific Helium-3 Advisor, he will expand this work to drive Pulsar's helium-3 research forward.

About the Topaz Project

The Topaz project is located in northern Minnesota, USA, where Pulsar is the first mover and holds exclusive leases. Drilling at the Jetstream #1 appraisal well reached a total depth ("TD") of 5,100 feet (1,555 meters) in January 2025, successfully penetrating the entire interpreted helium-bearing reservoir and beyond. Drilling of the Jetstream #2 appraisal well was completed on February 1, 2025, reaching a TD of 5,638 feet (1,718 meters). In August 2025, the Jetstream #1 well was successfully flow-tested using a wellhead compressor, delivering a peak gas flow rate of approximately 1.3 million cubic feet per day with a sustained flow of 7-8% helium (as helium-4). Recent laboratory analyses have also confirmed the presence of helium-3 in measurable concentrations, representing one of the highest naturally occurring helium-3 values publicly reported in a terrestrial gas reservoir. The forthcoming multi-well drilling campaign will build on these results to expand Pulsar's understanding of the reservoir and advance Topaz toward development.
