Pulsar Helium Inc. provided an update on progress at its 100% owned Topaz helium project in Minnesota. This includes positive results from a 2D seismic sweep survey, and an update on additional geophysical surveys from the ongoing exploration program. 1.1 km (0.7 mi) long 2D seismic sweep survey shows a seismic reflector identified at the same depth as gas intersected in Jetstream #1 appraisal well, and additional reflectors observed at depth.

Further 20.4km (12.7 mi) long 2 D seismic line scheduled to commence in July to assist in the placement of step out wells from Jetstream #1 appraisal well. The sweep line was 1.1km (0.7 mi) in length, in a N-S orientation, with receivers at 10m (33ft) interval, and located 150m (492ft) west of Jetstream #1. A 20.4km (12.,7 mi) long, east-west orientated 2D seismic line is scheduled to commence later in July. This will provide regional high-resolution data to complement the existing passive seismic and airborne gravity gradiometry (AGG) data.

The combination of this data will be used to assist the placement of step out well from Jetstream #1. Pulsar has also received processed AGG, magnetic and Lidar data from an infill survey flown in May covering an area of 190km2 (118mi2) which is now ready for interpretation. When combined with the AGG data acquired in 2022, the survey has a combined resolution of 150m (492ft) line spacing. A geophysical technique for mapping geological units and structure.

All technical data for Topaz has been transferred to Sproule International Ltd, which is expected to publish an updated resource calculation in July. In the State of Minnesota, the regulatory term is 'exploratory boring'. A seismic reflector is an interface between subsurface layers with contrasting acoustic impedances that reflects a portion of seismic wave energy back to the surface, allowing geophysicists to image and interpret subsurface structures.
