QIMC Expands District-Scale Natural Hydrogen System at Temiscamingue with New High-Grade Soil-Gas Results

Québec Innovative Materials Corp. (CSE: QIMC; OTCQB: QIMCF; FSE: 7FJ) (“QIMC” or the “Company”) has reported new high-grade soil-gas hydrogen anomalies from its fall 2025 sampling campaign at the Temiscamingue natural hydrogen corridor in Ontario, materially expanding the interpreted footprint of the system from 11 kilometres to approximately 15 kilometres.

The newly released results come from four additional westward sampling lines completed beyond previously disclosed work and further validate QIMC’s proprietary fault-controlled natural hydrogen exploration model. A total of 647 soil-gas samples were collected, with peak hydrogen concentrations reaching 2,843 ppm and multiple newly defined hotspot zones identified across several kilometres of lateral continuity.

“These results demonstrate not just continuity, but the emergence of a true district-scale hydrogen system,” said John Karagiannidis, President and CEO of QIMC. “The scale, consistency, and predictability we are observing support our long-term vision of natural hydrogen as a foundational, low-emission energy source capable of supporting future off-grid infrastructure.”

Across two of the newly sampled lines alone, 247 samples returned hydrogen values of up to 1,849 ppm, including 12 samples exceeding 1,000 ppm and 45 samples above 500 ppm. Importantly, gas composition analysis continues to confirm high-purity, abiotic natural hydrogen with no detected contaminants, reinforcing confidence in the underlying geological system.

The expanded footprint and demonstrated lateral continuity significantly strengthen QIMC’s strategy of developing scalable, fault-controlled hydrogen systems suitable for long-term monitoring, optimization, and integration with advanced analytics. The Company notes that these characteristics align directly with its broader geology-to-AI and off-grid energy strategy, particularly as demand grows for reliable, low-emission power solutions tied to energy-intensive computing and data infrastructure.

In parallel with exploration advances, QIMC continues to deepen its collaboration with local communities. The Company recently formalized its relationship with the Témiscamingue First Nation through a Memorandum of Understanding, establishing a cooperative framework for exploration and future development grounded in environmental stewardship, respect for traditional knowledge, and shared economic opportunity.

Looking ahead, QIMC’s upcoming Ontario–Québec winter exploration program will focus on continued monitoring, high-resolution geophysical surveys, radon–thoron integration, and preliminary drill-site selection in advance of a planned 2026 drilling program.

Montreal, Quebec--(Newsfile Corp. - December 18, 2025) - Québec Innovative Materials Corp. (CSE: QIMC) (OTCQB: QIMCF) (FSE: 7FJ) ("QIMC" or the "Company") is pleased to report new high-grade soil-gas hydrogen anomalies from four additional sampling lines completed west of its previously disclosed work within the Temiscamingue, Ontario natural hydrogen corridor. The new data, from the fall 2025 sampling campaign, materially expands the defined footprint of the hydrogen system from 11km to 15km and further validates QIMC's proprietary fault-controlled natural hydrogen exploration, and development model. These results also support QIMC's strategy of developing scalable, fault-controlled natural hydrogen systems capable of supporting future low-emission, off-grid energy applications.

Recent commercial developments in the natural hydrogen sector, including emerging hydrogen off-take frameworks tied to energy-intensive computing infrastructure, underscore the growing demand for reliable off-grid low-emission hydrogen supply. These market signals highlight the relevance of scalable, naturally sourced, off-grid hydrogen systems and reinforce the strategic value of district-scale hydrogen corridors capable of supporting future distributed energy applications.

Soil-Gas Survey Anomalies Confirm District-Scale Hydrogen System Expansion

A total of 647 soil-gas samples were collected across four new westward lines (L20W, L21W, L22W, and L24W). Results include a peak hydrogen concentration of 2,843 ppm on Line L24W, along with two newly defined hydrogen hotspot zones on Lines L20W and L21W. Across these two lines alone, 247 samples returned hydrogen values up to 1,849 ppm, including 12 samples exceeding 1,000 ppm and 45 samples above 500 ppm, indicating a robust, laterally continuous hydrogen anomaly over multiple kilometres.

"What we are demonstrating at Temiscamingue is not just continuity of hydrogen anomalies, but the emergence of a district-scale energy system," said John Karagiannidis, CEO of QIMC. "The scale, consistency, and predictability we're seeing support our long-term vision of natural hydrogen as a foundational energy source-one that can ultimately enable new forms off-grid infrastructure, including data-driven and AI-enabled systems."

Importantly, gas composition analyses continue to confirm the presence of high-purity, abiotic natural hydrogen, with no hydrogen contaminants detected. These results are being systematically integrated with QIMC's structural, geochemical, and hydrogeological datasets to advance winter exploration planning and drill-target definition.

District-Scale Platform Supporting QIMC's Geology-to-AI and Off-Grid Energy Strategy

The Company notes that the district-scale extent of the Temiscamingue natural hydrogen corridor is well suited to QIMC's integrated geology-to-AI and off-grid energy strategy. The demonstrated lateral continuity of hydrogen anomalies, repeatability of results, and structurally controlled system geometry provide a scalable geological framework conducive to long-term monitoring, data integration, and progressive optimization using advanced analytics.

"The scale and operational predictability of this hydrogen system validate our assessment of localized, low-emission off-grid energy architectures, with demonstrated applicability to distributed infrastructure such as remote computing environments and AI data-processing facilities," notes John Karagiannidis.

In support of this approach, QIMC plans to establish a regional office on Temiskamingue First Nation territory.

Radon-Thoron Measurements and Ongoing Analysis

In accordance with QIMC's natural hydrogen geological model, radon and thoron measurements were also collected across portions of the Temiscamingue project area during the 2025 field program. These measurements are intended to complement soil-gas hydrogen data by providing additional insight into subsurface permeability, structural pathways, and active degassing processes. The results of this work are currently being analyzed and integrated with existing geochemical and structural datasets and will be reported in a subsequent disclosure, subject to review and interpretation.

Community Collaboration and Indigenous Partnership

The Company wishes to thank the Témiscamingue First Nation and surrounding Ontario communities for their continued collaboration and support. QIMC has recently formalized this relationship through a Memorandum of Understanding (MOU) with TFN, recognizing that the exploration area lies within TFN's traditional hunting and cultural territories.

The MOU establishes a framework for cooperative exploration and future development, emphasizing respect for traditional knowledge, environmental stewardship, local employment opportunities, and shared economic benefits. QIMC remains committed to ensuring Indigenous and local communities are active partners in the advancement of natural hydrogen exploration.

Next Steps - Winter Exploration Program

QIMC's upcoming Ontario-Québec winter exploration program will include:

• Continued data collection from eight existing monitoring and measurement wells in the St-Bruno-de-Guigues area
• High-resolution geophysical surveys to refine subsurface structural interpretation, complemented by radon-thoron measurements
• Preliminary drill-site selection in advance of a planned 2026 drilling program
• Full integration of Ontario datasets into QIMC's Ontario-Québec Hydrogen Corridor Model
