Target Formation HEVI's Primary Geological Target: The Deadwood Formation Regional Data Used Well logs, seismic, and aeromagnetic data on the Deadwood used to select drill targets. Targeting Basement Highs Highest concentrations of helium typically found near regional basement (Precambrian) highs, commonly found in the Deadwood.1 Shale Deadwood Sand Reservoir Simple Drilling Process Helium drilling similar to conventional natural gas drilling simple, lower-cost vertical drilling and completions. Nitrogen Carrier Gas Nitrogen is primary carrier gas in SK helium with little associated CO2, nitrogen can be environmentally vented, providing cost advantages during helium extraction and purification.2,3 Nitrogen charged resources: Rich in Helium The Deadwood formation has the highest concentrations of helium in Southern Saskatchewan² Radioactive decay of the uranium in southern Saskatchewan's basement rocks has produced significant helium resources.² CORPORATE PRESENTATION | TSXV: HEVI Basement Up to: PROVEN HELIUM CONTENT¹ 2.0% Deadwood Formation HISTORIC NITROGEN CONTENT¹ In excess of: >95% HELIUM EVOLUTION 1 Emerging Ideas, Industrial Technology: Helium; Cormark Securities; 2020 2 Helium in Southwestern Saskatchewan: Accumulation and Geological Setting; Melinda Yurkowski; 2016 3 Global Helium Market Update; Edison Investment Research; 2021 19
