Pulsar Helium Commences Multi-Well Drilling Programme at Minnesota Topaz Project

• Drill rig and supporting equipment mobilised to Topaz Project site in Minnesota, with first well Jetstream #3 expected to commence drilling this week
• Programme comprises up to ten wells targeting helium-bearing zones at depths between 1,500 to 3,900 feet, operating on a 24-hour basis
• Campaign designed to define reservoir geometry, confirm continuity between well locations, and quantify the resource
• Jetstream #1 well delivered peak flow rates of approximately 1.3 million cubic feet per day with sustained helium concentrations of 7 to 8 per cent in August 2025
• Laboratory analyses confirmed presence of helium-3 in measurable concentrations, representing one of the highest naturally occurring helium-3 values publicly reported in a terrestrial gas reservoir

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) is a helium exploration and development company focused on primary helium occurrences not associated with hydrocarbon production. The company's portfolio consists of the Topaz helium project in Minnesota, USA, and the Tunu helium project in Greenland.

Drilling Campaign Mobilisation and Commencement

The drill rig and ancillary equipment have been mobilised to the Topaz Project site, with arrival scheduled for Wednesday. Timberline Drilling Inc. will operate a Christensen CT20 rig with a drilling depth capacity of 8,000 feet. Drilling of the first well, Jetstream #3, is anticipated to commence later this week.

Pulsar personnel, including the company's President and CEO, Chief Financial Officer, and Operations Manager, are on site overseeing final preparations. The rig features safety, ergonomic and environmental design characteristics, with truck or crawler mounted versions available for transport and manoeuvrability.

Operations will run on a continuous 24-hour basis using rotating crews. The programme will comprise up to ten wells targeting helium-bearing zones at depths between 1,500 to 3,900 feet. Drill depths will be refined based on geological modelling to ensure complete penetration of the reservoir at each location.

Reservoir Definition and Resource Quantification Objectives

Data collected throughout the campaign will include gas shows, core samples, and downhole measurements, which will be analysed in real time. The company stated these results will enable it to refine its reservoir model, confirm continuity between well locations, and identify sites for future production infrastructure.

The programme is designed to define the geometry, extent, and productivity of the helium-bearing reservoir identified in previous drilling and flow-testing campaigns. For context, helium concentrations above 0.3 per cent are generally considered economically viable for commercial production.

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

"The mobilization of the drill rig signals the start of an exciting new phase at Topaz. Building on the strong results from Jetstream #1 and #2, this next program is critical in confirming the scale of Minnesota's helium potential. Each well will bring us closer to quantifying the resource, advancing Topaz toward commercial development, and reinforcing Pulsar's role in strengthening U.S. helium supply chains."

Previous Drilling Results and Project Background

The Topaz project is located in northern Minnesota, USA, where Pulsar holds exclusive leases. Drilling at Jetstream #1 appraisal well reached a total depth of 5,100 feet in January 2025, penetrating the entire interpreted helium-bearing reservoir. The Jetstream #2 appraisal well was completed on 1 February 2025, reaching a total depth of 5,638 feet.

In August 2025, the Jetstream #1 well was flow-tested using a wellhead compressor. The test delivered a peak gas flow rate of approximately 1.3 million cubic feet per day with a sustained flow of 7 to 8 per cent helium (as helium-4).

Recent laboratory analyses confirmed the presence of helium-3 in measurable concentrations. The company stated this represents one of the highest naturally occurring helium-3 values publicly reported in a terrestrial gas reservoir. Helium-3 is a rare isotope with applications in quantum computing, medical imaging, and national security.

Looking Ahead

The current drilling campaign is designed to expand the company's understanding of the reservoir and advance Topaz toward development. Data collected from the up to ten wells will be used to refine reservoir models and confirm continuity between well locations.

The company stated the forthcoming multi-well drilling campaign will build on previous results at Jetstream #1 and #2. Following completion of the drilling programme, the company is expected to use the data to support resource estimation and inform future development decisions at the Topaz Project.
