Pulsar Helium Inc. announce that on March 13th, it received the analytical laboratory results for gas samples from the Jetstream #1 appraisal well at the Topaz helium project in Minnesota. A total of eleven samples were analysed, four at Isotech Laboratories Inc. (Isotech) and seven at Smart Gas Sciences LLC (Smart Gas). Helium contents of up to 13.8% were measured, specifically from a sample obtained at 1,801ft in-hole depth.

The full suite of gas data was sent to Dr Peter Barry, a noble gas isotope geochemist and Associate Scientist (an advisor to the Company) at the Woods Hole Oceanographic Institution (WHOI). He concluded that the value of 13.8% helium represents a minimum source estimate for helium, due to the clear presence of small amounts of atmospheric (air) contamination in the samples. The presence of this contamination decreases the measured helium content relative to the true source helium concentration.

The Jetstream #1 appraisal well reached total depth (TD) of 2,200 feet (671 meters), and on February 29th, the Company announced concentrations of up to 12.4% helium measured by the on-site quadrupole mass spectrometer. Additional samples were collected at depth while drilling, stored in Isotube gas canisters and then sent to Isotech and Smart Gas for laboratory-based gas chemistry analysis. The revised helium content of 13.8% is considered more reliable and more accurate than those obtained via the on-site quadrupole mass spectrometer.
