Pulsar Helium Inc. (Pulsar) has started drilling to deepen its Jetstream #1 appraisal well at the Topaz project in Minnesota, US. The operation began on 2nd January 2025, marking a key step in the company’s plans to assess the full height of a high helium concentration reservoir.
The drilling aims to extend the well by at least 1,640 feet (500 metres) to a total depth of 3,840 feet (1,170 metres). According to Pulsar, the work is expected to conclude later this week. Open-hole wireline logging will begin immediately after drilling, with flow testing scheduled once the well stabilises.
Initial results from February 2024 revealed helium concentrations of up to 14.5% in the reservoir, far exceeding the industry’s economic threshold of 0.3%. The Jetstream #1 well also recorded carbon dioxide (CO2) levels above 70%, which Pulsar believes will further bolster project economics.
“Deepening of the Jetstream #1 well has commenced and is progressing extremely well,” said Thomas Abraham-James, President and CEO of Pulsar Helium. “The assessment of the full height of the previously discovered high helium concentration reservoir is a key stage in progressing Topaz. Previous drill data indicated that we only reached the top of the reservoir and that it may extend for a further 1,640 feet.”
Next steps for Topaz
The drill pad for the second well, Jetstream #2, is complete, with a conductor rig expected to be installed by 8th January 2025. The company views this expansion as key to its broader strategy of addressing rising global helium demand, as it progresses toward potential production.
Pulsar Helium operates as a first mover in helium exploration at both the Topaz project in Minnesota and the Tunu project in Greenland. The company emphasises that neither project is associated with hydrocarbon production, differentiating its portfolio in the helium market.
Further updates on the drilling progress and subsequent reservoir testing are expected in the coming weeks.
