Pulsar Helium continues to report favourable outcomes from its ongoing geophysical exploration and drilling activities southeast of Babbitt. On 4th October, the Canadian company announced that a 12.7-mile vibroseis survey conducted along the Dunka River Road revealed both eastward and westward extensions of the velocity anomaly tied to the helium-bearing zone.
According to the company’s recent statement, the processed seismic data indicates a continuous reflective layer at the helium-bearing interval, which was initially identified in their Jetstream No. 1 well. This reflective layer has been imaged to extend approximately 1.5 kilometres to the west and 2 kilometres to the east of the well. The results suggest a significant expansion of the helium-bearing zone.
Seismic surveys, which use sound waves to create underground images, allow companies like Pulsar to map how rock formations are arranged beneath the surface. Specifically, the vibroseis method involves shaking the ground with a specialised truck rather than using explosives. This process is coupled with geophones, which capture the reflected sound waves, providing detailed information about subsurface formations. In the data, gas deposits are typically identified as areas of lower seismic velocity.
The extension of the seismic feature in the helium-bearing zone provides Pulsar with confidence that future drilling operations could more accurately target productive areas. This is a crucial development as the company prepares to drill additional wells in the coming months. The cost of drilling a single gas production well is significant, averaging around a million dollars, so accurate targeting is essential.
Further analysis from the August survey revealed additional potential, with other reflective packages visible in the seismic data. These packages suggest the presence of additional fracture zones, which are areas where gas accumulates. Targeting these zones is essential for producing economically viable helium.
Josh Bluett, Pulsar’s technical manager, commented that the seismic data shows the productive helium-bearing interval intersected in Jetstream No. 1 extends laterally. He added that the new active seismic data supports earlier interpretations from passive seismic and airborne geophysical studies. This new information is highly promising as the company prepares for its upcoming drilling programme. Last year’s passive seismic survey had also indicated a westward extension of the gas-bearing zone, reinforcing the latest findings.
Pulsar Helium’s continued success in mapping and identifying potential helium-bearing zones through seismic exploration marks an encouraging step forward. As they prepare for additional drilling, these results offer valuable insights into the next stages of development.
Pulsar Helium Inc (TSXV:PLSR) is a leading primary helium exploration and development company. Its flagship Topaz Project in Minnesota, USA, flowed North America’s highest concentration of helium at 14.5%. Commercially viable helium project concentrations begin @ 0.3%.
