QIMC Reports High-Purity Natural Hydrogen Discovery at Nova Scotia’s Bennett Hill Project

Quebec Innovative Materials Corp. has reported elevated concentrations of naturally occurring hydrogen from its first drill hole at the Bennett Hill project in Nova Scotia, strengthening the company’s view that a potentially significant district-scale hydrogen system exists within the region.

The results come from diamond drill hole DDH-26-04 at the Bennett Hill site, located approximately 15 kilometres from the company’s Eatonville Road exploration area in the Advocate region of Nova Scotia. According to Quebec Innovative Materials Corp., the upper 100 metres of the borehole returned elevated hydrogen concentrations, including a nine-metre interval where four readings reached or exceeded 4.03% hydrogen, the upper measurement limit of the field analyser being used.

Because the analyser reached saturation during testing, the reported values represent minimum concentrations, with the actual hydrogen content potentially higher. To quantify concentrations at greater depths, the company has deployed a second analyser with a broader measurement range and is continuing testing below the 100-metre level.

One of the most significant aspects of the findings is the reported absence of other gases typically associated with hydrocarbon systems. Methane and carbon dioxide were both recorded at below or near detection limits throughout the hydrogen-rich interval, creating what the company describes as a “clean” hydrogen signature.

QIMC believes the results may indicate an active and efficient migration pathway capable of transporting hydrogen from deeper geological sources towards the surface. The company also notes that the findings are consistent with earlier soil-gas anomalies identified at Bennett Hill and align with its broader exploration model for the region.

The discovery is particularly notable because it comes from a separate project area approximately 15 kilometres from previous drilling locations at Eatonville Road. Company officials say this supports their working hypothesis that the hydrogen system extends across a much larger geological district rather than being confined to a single exploration target.

Chief Executive Officer John Karagiannidis described the results as an important milestone for the company, highlighting both the elevated hydrogen concentrations and the lack of methane and carbon dioxide contamination. He said the decision to introduce a higher-range analyser reflects the need to accurately quantify hydrogen concentrations encountered below 100 metres, with further results expected once testing and calibration have been completed.

The findings are also being incorporated into QIMC’s proprietary R2G2 exploration framework, which is designed to identify natural hydrogen accumulations associated with reactivated rift and graben geological structures.

Scientific analysis conducted by Professor Marc Richer-LaFlèche suggests the results may have implications beyond the immediate project area. He stated that the consistency of gas signatures observed at Bennett Hill and previous drilling sites supports the interpretation of a large-scale, structurally controlled hydrogen system associated with the Cobequid Fault Zone and the broader Cobequid-Chignecto Fault System.

According to the company, the upper section of the borehole intersects intensely fractured and oxidised volcanic and intrusive rocks, creating a highly permeable environment for gas migration. The similarity in gas composition across different geological settings is seen as evidence that hydrogen generation may originate deep within the continental crust rather than being controlled by local surface geology.

The results add to growing global interest in naturally occurring, or “white”, hydrogen as a potential low-carbon energy source. Exploration activity has increased significantly in recent years as companies seek to determine whether naturally generated hydrogen can be produced commercially and at scale.

With drilling and deeper gas analysis still under way, QIMC said further results from Bennett Hill will be released once validation and calibration work have been completed, potentially providing additional insight into the scale and commercial potential of the emerging natural hydrogen play in Nova Scotia.
