From Ann's 4th FEB 2021 The field work will involve validation of desktop surface mapping and ambient testing for helium and hydrogen as well as the geochemical survey which involves soil sampling for helium, hydrocarbons and hydrogen. Field activities and geochemical survey to commence early Q2, at the conclusion of the Northern Territory wet season• The geochemical survey is designed to identify the presence of an active helium system (and hydrocarbon and hydrogen) within EP127
Ambient testing: In most helium leak testing applications, a mass spectrometer is used to detect helium. Although, it is also possible to use a residual gas analyser.
Geochemical survey: A survey involving the chemical analysis of systematically collected samples of rock, soil, stream sediments, plants, or water; this expression may be further modified by indicating specif. the material sampled, as, for example, geochemical soil survey
