Seems like this one might be a good long. Might be worth catching it now.
"Thor Energy Plc is delighted to announce the preliminary results of its Phase-2 soil air geochemistry survey at the Company's 80.2%-owned HY-Range Project (RSEL 802) in South Australia (Figure 1). The results build upon and validate the Phase-1 survey completed in Q2 2025, recording natural hydrogen readings up to 3% (30,000 ppm) on licence (Figure 2A), whilst successfully validating three of the Company's highest-priority exploration focus areas (Figure 2B and 2C)."
