QIMC DEMONSTRATES MULTI-SEASON CONSISTENCY OF HYDROGEN ANOMALIES ACROSS THREE EXPANDED DRILL-READY TARGET ZONES AT WEST ADVOCATE, NOVA SCOTIA

Results from Quebec Innovative Materials Corp.'s most recent geological site work program conducted during the fall and early winter of 2025 reinforce the strength, continuity and geological significance of hydrogen anomalies initially identified during the company's summer 2025 campaign. In total, 452 soil-gas samples were collected across the West Advocate project area. Multiseason results demonstrate the consistent persistence of hydrogen anomalies across three expanded, drill-ready target zones along the West Advocate structural corridor in Nova Scotia, including in the vicinity of Eatonville Road. Data collected under differing seasonal and atmospheric conditions confirm that these anomalies are spatially coherent and structurally controlled, materially derisking target definition and advancing the project toward prioritized drilling.

John Karagiannidis, president and chief executive officer of Quebec Innovative Materials, commented: "These results represent a meaningful inflection point for the West Advocate project. The confirmation of consistent hydrogen anomalies across three expanded target zones, validated through multiseason data, significantly strengthens our confidence in the scale and integrity of the underlying system. We are no longer dealing with isolated anomalies; we are systematically defining drill-ready hydrogen targets using repeatable, science-driven methods. This work materially derisks the project and positions West Advocate as a cornerstone asset within QIMC's natural hydrogen portfolio."

Building on this multiseason validation, Quebec Innovative Materials' latest program focused on increasing sampling density across previously identified priority areas to refine and consolidate drill-ready target definition. Despite well-recognized seasonal and atmospheric influences on soil-gas measurements, the company's integrated analytical approach confirms that hydrogen anomalies persist across survey periods and remain aligned with mapped structural controls. This outcome provides a robust, derisked framework for prioritizing target zones in the Advocate area.

Together, the confirmation of multiseason persistence and the consolidation of three expanded drill-ready target zones meaningfully reduces geological risk and positions West Advocate as a scalable, repeatable natural hydrogen development platform that can be systematically replicated across Quebec Innovative Materials' more than 3,773 claims in Nova Scotia and its broader landholdings in Minnesota and the Quebec-Ontario region rather than a single-target exploration play.

What is a natural hydrogen target zone?

Each natural hydrogen target zone defined at West Advocate represents a structurally coherent area defined by the convergence of multiple independent geological and geochemical indicators, including:

• Persistent hydrogen (H2) anomalies observed across multiple seasons;
• Coincident radon-thoron responses indicating deep-sourced gas migration pathways;
• Structural alignment with mapped faults and fracture corridors.

These target zones form the core building blocks of Quebec Innovative Materials' exploration and development strategy, enabling the company to systematically advance multiple drill-ready opportunities within a single hydrogen corridor, rather than relying on a single, binary exploration outcome.

Why Z-score normalization is used

Seasonal variability and atmospheric conditions such as temperature and barometric pressure are well-known challenges in soil-gas exploration and can obscure true geological signals if absolute gas concentrations are considered in isolation. To address this, Quebec Innovative Materials and INRS applied Z-score normalization independently to each soil-gas data set.

In simple terms, Z-score normalization measures how strongly each hydrogen reading deviates from its local background, rather than relying solely on absolute concentration values. This approach removes seasonal and atmospheric bias and allows direct, apple-with-apple comparison across survey periods.

When normalized data sets are integrated, hydrogen anomalies that persist across seasons are interpreted as robust, structurally controlled geological features, rather than transient environmental effects. This significantly derisks target definition and supports the identification of drill-ready hydrogen target zones, as detailed in the technical interpretation below.

The work was carried out by Quebec Innovative Materials in collaboration with the Institut national de la recherche scientifique (INRS) under the scientific leadership of Prof. Marc Richer-LaFleche, providing academic scientific oversight and methodological rigour.

Prof. Richer-LaFleche commented: "The second soil-gas survey conducted during the fall and early winter of 2025 confirms that hydrogen anomalies initially identified during the summer program persist despite differing seasonal and atmospheric conditions. After normalizing the data sets to account for temperature and pressure effects, the results clearly delineate three highly anomalous hydrogen sectors at West Advocate. The persistence and spatial coherence of these anomalies strongly support a structurally controlled geological hydrogen system."

Integrated technical interpretation

According to Quebec Innovative Materials' scientific analysis completed in collaboration with INRS, soil-gas data collected during the July (summer) and October (fall) geological sampling campaigns in 2025 were assessed independently to account for seasonal differences in atmospheric and environmental conditions known to influence soil-gas concentrations.

Summer sampling was conducted under warmer conditions, with median temperature, atmospheric pressure and relative humidity values of 26 C, 1,021.6 hectopascals and 57.3 per cent, respectively. Fall sampling was completed under cooler conditions, with median values of 14.2 C, 1,025.4 hectopascals and 53.2 per cent, respectively. Variations in temperature and atmospheric pressure are recognized drivers of barometric pumping, a process that can suppress measured soil-gas concentrations during colder periods and higher-pressure regimes. Previous work by Avendano et al. (2021) identifies the Canadian Atlantic coastal region and the Gulf of St. Lawrence as areas with elevated barometric-pumping efficiency potential.

Direct comparison of raw hydrogen concentrations between the two sampling periods highlights an expected seasonal offset. Median hydrogen concentrations measured during the summer survey were 265 parts per million (volume), compared with 135 ppm (v) during the fall survey. To address this seasonal bias, hydrogen background thresholds were estimated independently for each data set. The upper background limit for hydrogen was determined to be less than 318 ppm (v) for summer samples and less than 160 ppm (v) for fall samples.

To enable meaningful cross-season comparison, hydrogen concentrations from each sampling period were normalized using Z-score calculations, computed separately for the July and October data sets. The compiled Z-score data set integrates normalized hydrogen anomalies from both sampling periods and delineates three spatially coherent, highly anomalous hydrogen sectors (zones I, II and III). These anomalies persist across survey periods, indicating a robust, geologically structurally controlled hydrogen system.
