Records up to 3% Natural Hydrogen at HY-Range
Thor Energy PLC has announced preliminary results from its Phase-2 soil air geochemistry survey at the HY-Range Project in South Australia, recording natural hydrogen readings up to 3% (30,000 ppm), significantly exceeding background levels and validating three key exploration areas. These results build upon Phase-1 findings and have been achieved with rigorous sampling techniques that substantially reduce the risk of error or contamination. The elevated surface geochemistry strongly correlates with the company's geological models, indicating the potential for economic volumes of natural hydrogen. Thor Energy is now preparing to announce the award of a 2D seismic acquisition program to further define drilling targets. Disclaimer*

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). Highlights: · Elevated Natural Hydrogen Concentrations: Phase-2 recorded highly elevated natural hydrogen readings, reaching a maximum of 3% (approximately 60,000 times background). · Validation of Focus Areas: Consistently repeated high values, ranging from several hundred to several thousand times background, were recorded and identified across high-grade exploration areas (Mallala, Lochiel, & Crystal) during Phase-1. · Rigorous Data Integrity: Evolved sampling techniques, in which depth, duration and material variables were tested alongside controls, strongly indicate the presence of highly active natural hydrogen generation. The risk of sampling error or anthropogenic (human-made) contamination has been substantially reduced at the HY-Range Project (RSEL 802). · Compelling Geological Correlation: Anomalously high surface geochemistry aligns with Thor's geological models and the crustal-scale basement architecture, faulting, and focusing mechanisms necessary to deliver economic volumes of natural hydrogen. · Development of Thor's natural hydrogen and helium exploration methodologies: This survey further refines in-house geochemical sampling methodologies and continues to evolve Thor's integrated appro...
