QIMC Extends Natural Hydrogen Footprint in Nova Scotia with 2nd Major Discovery at East Advocate - 4km Line with Soil Gas Samples Averaging 623 Ppm with a High of 2,247 Ppm

Montreal, Quebec -- (Newsfile Corp. - September 3, 2025) - Quebec Innovative Materials Corp. (CSE: QIMC) (OTCQB: QIMCF) (FSE: 7FJ) ("QIMC" or the "Company") is pleased to announce the confirmation of a second major natural hydrogen zone in Nova Scotia. Following the Company's record-setting results at West Advocate, QIMC and its research partner INRS have now identified a continuous 4 km anomalous line at Eastern Advocate (Bennett Hill Road section), averaging 623 ppm H₂ with a high of 2,247 ppm.

These results underscore Nova Scotia's emergence as a district-scale natural hydrogen hub in North America, with further results pending from additional at Southampton and Springhill.

Discovery Highlights - East Advocate

• 4 km anomalous transect northeast of the West Advocate discovery.
  
• 47 soil-gas samples collected and analyzed on-site by INRS.
  
• Average concentration: 623 ppm H₂; median 520 ppm H₂.
  
• Peak value: 2,247 ppm H₂.
  
• Frequency: 36% of samples between 500-1,000 ppm and 11% between 1,000-2,000 ppm.

"These Eastern Advocate results firmly establish that Nova Scotia hosts not just isolated anomalies, but an expanding hydrogen system with scale," said John Karagiannidis, President & CEO of QIMC. "With two confirmed multi-kilometre zones in less than two months, and more results pending at Southampton and Springhill, QIMC is leading the charge in unlocking Nova Scotia as one of the most promising natural hydrogen addresses in North America."

Geological Context

To continue the evaluation of the natural hydrogen potential of the Cobequid Fault Zone (Nova Scotia), the QIMC and INRS team completed a second transect located northeast of the Reid section of West-Advocate. One of the sub-objectives of the study is to assess the relative scale of hydrogen transfer processes along the large Cobequid fault zone.

The work was carried out from 18 to 20 July 2025 under sunny weather conditions that were particularly favourable for the collection of Soil-Gas samples (average temperature of 25oC, average atmospheric pressure of 989 HPa and average relative humidity of 64%). A total of 47 samples were collected from a 4 km section along Bennett Hill Road located in the East Advocate area.

The mean and median hydrogen concentrations measured in the soils of this sector are particularly high with values of 623 and 520 ppm respectively. Measured values along the Bennett Hill section range from 0 to 2247 ppm.

500-1000 ppm: 17 samples (36%)
1000-2000 ppm: 5 samples (11%)
More than 2000 ppm: 2 samples (4.3%)

These high concentrations of hydrogen in the soils of Bennett Hill are observed 12 km northeast of the Reid-Eatonville Zone of the West-Advocate sector. The observation of strong H₂ anomalies in the Bennet Hill area suggests, a priori, that the system responsible for hydrogen production could be of multi-kilometre extension. This scenario is plausible considering the importance of the Cobequid Fault Zone in Nova Scotia and the presence of igneous rocks potentially a source of hydrogen in the Cobequid Highlands.

The highest hydrogen concentrations are observed mainly in the Cobequid Highlands area and more specifically in a complex geological domain characterized by the presence of Hadrynian (Proterozoic) volcanic rocks of the Jeffers Fm, Devonian sedimentary rocks of the Rapid Brook Fm, granitic rocks of the Apple River pluton. All these rocks show cataclastic facies suggesting the presence of secondary structures (faults) probably associated with the deformation corridor of the main Cobequid Fault. It is possible that the increase in porosity and permeability of cataclastic rocks could explain, among other things, the hydrogen enrichment observed in the soils of this area. Subsequent petrophysical studies will have to verify this hypothesis.

"These Bennett Hill values reinforce the interpretation of the Cobequid Fault as a first-order hydrogen system," noted Prof. Richer-LaFlèche, INRS who supervised the field work and analysis. "The structural complexity, combined with igneous and sedimentary units, provides the perfect environment for large-scale hydrogen generation and retention."

Next Steps

With discoveries at both West Advocate (5,558 ppm peak) and East Advocate (4 km continuous line - 2,247 ppm peak), QIMC is further consolidating its land holdings and preparing for Phase 2 and Phase 3 beginning early September.

"Nova Scotia is no longer just prospective - it is emerging as a hydrogen hub for North America," added Karagiannidis. "QIMC will continue advancing aggressively, with Southampton and Springhill results expected to further expand the scale of this district."
