Dr. 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.

Strategic Importance of Helium-3

Article content

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.
