QIMC Confirms Fourth Major Natural Hydrogen Zone in Nova Scotia with Soil-Gas Results up to 4,850 ppm - 2 km Continuous Anomaly Along Windsor-Cumberland Fault

Executive Summary

• QIMC confirmed a fourth major natural hydrogen zone in Nova Scotia’s Little Forks‑Springhill area, with a peak soil‑gas concentration of 4,850 ppm.
• The anomaly extends ~2 km along the Windsor Group–Cumberland Group fault, adding to three previously announced discoveries and supporting a regional clean‑ammonia development model.
• A total of 208 soil‑gas samples were collected over 19.9 km; 24 readings exceeded 500 ppm, including multiple high‑level intercepts (1,500–2,999 ppm).

Key Details

• Peak concentration: 4,850 ppm H₂ in soil gas – highest recorded in the province to date.
• Sample coverage: 208 samples from three sections (Little Fork and Salt Spring sections) spanning 19.9 km of public roads, collected 8‑9 Aug 2025 under sunny conditions (30.7 °C, 1011.7 hPa, 33.7 % RH).
• Reading distribution:

• 24 readings >500 ppm

• 4 readings between 1,500–1,999 ppm
• 2 readings between 2,000–2,999 ppm
• Geological context: Zone lies on a fault boundary separating the Windsor Group (evaporite barrier) from the Cumberland Group (potential reservoir). Evaporites act as seals; Ragged Reef sandstones provide reservoir quality.
• Strategic implication: Confirms the presence of multiple high‑potential hydrogen corridors across Nova Scotia, underpinning plans for a regional clean ammonia production hub.
• Next steps: QIMC and INRS teams will return to the site on 5 Oct 2025 to commence further development phases (e.g., detailed geophysical work, drilling planning).
• Technical validation: Prof. Marc Richer‑Laflèche, P.Geo., reviewed and approved all methodologies, data, and interpretations, confirming compliance with industry standards for hydrogen exploration.

Notable Quotes

“This fourth discovery validates our exploration thesis: Nova Scotia possesses the right geological conditions—faulted and folded reservoirs sealed by impermeable evaporites—that can host large‑scale natural hydrogen accumulations.” – John Karagiannidis, President & CEO, QIMC

“The Ragged Reef sandstones provide excellent reservoir potential, the Windsor Group evaporites act as barriers, and the local geothermal gradient provides the driving energy for hydrogen migration.” – Prof. Marc Richer‑Laflèche, INRS
