Thor Energy Confirms Strong Natural Hydrogen Potential with Up to 3% Hydrogen Detected at HY-Range Project

Thor Energy has announced encouraging preliminary results from its Phase-2 soil air geochemistry survey at the HY-Range Natural Hydrogen Project in South Australia, revealing natural hydrogen concentrations of up to 3% (30,000 parts per million). The findings represent a significant advancement in the company’s exploration efforts and further validate several of the project’s highest-priority target zones, strengthening the case for the presence of a potentially viable natural hydrogen system within the licence area.

The Phase-2 survey was designed as a follow-up to the company’s Phase-1 exploration program conducted in 2025. During the earlier campaign, Thor identified multiple hydrogen anomalies across the project area, suggesting the possibility of naturally occurring hydrogen generation and migration. Building on those findings, the latest survey focused on confirming and refining the most promising targets. The results exceeded expectations, with hydrogen concentrations substantially higher than those recorded during the initial phase. Several sampling locations produced readings hundreds to thousands of times greater than normal atmospheric hydrogen levels, while the highest recorded value reached 3%, highlighting the strength of the anomalies detected.

The survey specifically targeted three key exploration areas within the HY-Range Project: Mallala, Lochiel, and Crystal. According to Thor Energy, all three zones returned repeat anomalous hydrogen readings, confirming the consistency of the results. The repeatability of these measurements is considered particularly important because it indicates that the hydrogen signatures are persistent geological features rather than isolated or temporary occurrences. This consistency significantly enhances confidence in the project’s exploration model and supports the potential for ongoing natural hydrogen generation within the region.

A major objective of the Phase-2 program was to improve data quality and reduce uncertainty through the refinement of sampling methods. Thor tested a range of techniques, including different sampling depths, collection durations, materials, and quality-control procedures. These measures were implemented to minimize the risk of contamination and eliminate the possibility of false-positive readings. The company believes the enhanced methodology has resulted in a more robust and reliable dataset, providing stronger evidence that the elevated hydrogen concentrations are genuine and linked to active geological processes occurring beneath the surface.

In addition to the geochemical results, Thor reported a strong relationship between elevated hydrogen concentrations and several key geological features identified within the project area. The anomalous hydrogen readings align closely with interpreted basement structures, fault zones, and fluid migration pathways. These geological elements form a central part of the company’s exploration model and are widely regarded as critical components in the formation and accumulation of natural hydrogen systems. The correlation between surface geochemistry and subsurface structures provides further support for the existence of a potentially significant hydrogen resource.

Looking ahead, Thor Energy plans to advance the project through a major 2D seismic acquisition program across the licence area. The company expects to announce the contract award for the survey in the near future. The seismic program, which is already fully funded, will provide a detailed understanding of the subsurface geological architecture beneath the most prospective target areas. By integrating seismic data with the existing geochemical results, Thor aims to identify and prioritize future drilling locations. The program represents an important milestone in the company’s strategy to move from exploration toward drill-ready prospects and evaluate the commercial potential of natural hydrogen resources within the HY-Range Project.
