QIMC Details Multiple Shallow Hydrogen-Bearing Zones in Drill Hole 26-02 and Advances Integrated Interpretation of Holes 1 and 2; Drill Hole 2 to be Extended to 700 Metres; Drill Mobilized for Hole 3

Integrated drilling and downhole datasets delineate structurally controlled hydrogen system across multiple domains in Hole 26-02 guiding deeper targeting

Québec Innovative Materials Corp. (CSE: QIMC,OTC:QIMCF) (OTCQB: QIMCF) (FSE: 7FJ) ("QIMC" or the "Company") is pleased to provide an update on the ongoing integrated interpretation of drill holes 1 and 2 from its hydrogen exploration program.

Preliminary results from drill hole 26-02 have identified multiple shallow hydrogen-bearing intervals across a vertical profile extending from near surface to 500 metres depth. The Company's current interpretation indicates that several of these intervals are spatially associated with major structural features encountered in the hole.

Hydrogen and associated gas measurements reported herein were obtained from dissolved gas samples extracted from drill water collected at regular intervals (approximately every 3 metres) at the wellhead during drilling operations. Reported values are preliminary and subject to ongoing integration with geological, structural, geophysical, and petrophysical datasets. Quality control procedures, sensor specifications, and analytical protocols will be summarized in a future technical update.

QIMC is currently integrating geochemical, geological, structural, downhole geophysical, and petrophysical datasets from Holes 1 and 2 as part of its ongoing work to refine its subsurface hydrogen model. Based on results obtained to date, the Company plans to extend drill hole 26-02 beyond its initial 500-metre depth to approximately 700 metres, as the hydrogen-bearing system is interpreted to remain open at depth based on current drilling.

CEO COMMENTARY

"The continued advancement of Hole 26-02, combined with the integrated interpretation of our first two drill holes, marks an important step in refining our understanding of this hydrogen system. We are also pleased to confirm that the drill has been mobilized for Hole 3, marking a significant milestone as we continue to advance our exploration program at pace," said John Karagiannidis, President & Chief Executive Officer of QIMC.

"The presence of hydrogen across multiple domains over a 500-metre interval, together with the structural controls we are observing, provides a strong technical basis to extend the hole deeper. Importantly, the addition of downhole geophysical and petrophysical datasets enhances our ability to characterize permeability, fluid pathways, and subsurface conditions as we advance toward the next phase of our program."

KEY HIGHLIGHTS

• Multiple hydrogen-bearing intervals identified from near surface to 500 metres depth

• Peak hydrogen concentrations exceeding 1,000 ppmV in selected intervals

• Hydrogen anomalies observed in association with major fault zones intersected at 95.0-104.3 metres and 126.8-159.0 metres as well as deeper in domains 5 and 6

• Six geochemical domains defined across the current drill profile

• Integrated interpretation of Holes 1 and 2 now underway

• Drill hole 26-02 planned to be extended to approximately 700 metres

• Downhole geophysical and petrophysical surveys completed by SEMM Geoservice, including televiewer imaging, downhole geophysics, H2 measurements, permeability and porosity testing, density logging, and electrical resistivity tomography

PROJECT GEOLOGIST COMMENTARY

"What is particularly significant in Hole 26-02 is the recurring association between hydrogen-bearing fluids and structurally deformed intervals," said Edward Procyshyn, P.Geo., Senior Project Geologist for QIMC.

"The highest hydrogen concentrations are concentrated within the upper portions of the major fault system between 128 and 146 metres, where strong alteration and brecciation are observed. The association of hydrogen with CO and the absence of methane and carbon dioxide in certain sampled intervals is interpreted to be consistent with a deep hydrogen-bearing fluid system. The system is currently interpreted to remain open at depth based on results obtained to date, and the additional downhole datasets are expected to assist in refining permeability pathways and fluid migration models."

Geological Setting

The drill hole intersected a sedimentary sequence consisting of interbedded:

• Mudstone
• Siltstone
• Sandstone
• Conglomerate

These units are consistent with turbidite sequences comparable to:

• Franciscan Formation
• Taconic orogeny

Two major fault zones were intersected. These structures are interpreted to represent potential pathways for fluid migration.

Lithology and Structural Observations - Drill Hole 26-02 - Project Geologist Ed Procyshyn

Drill hole 26-02, from a depth of 4 m to the bottom of the hole at 500 m, intersected predominantly sedimentary rocks, with occasional quartz veins and thin (<20 cm) granitic dikes and sills occurring at widely spaced intervals.

Additional shear zones (<25 cm wide), hosting breccia fragments and gouge, were observed at irregular intervals within an otherwise firmly indurated and locally metamorphosed sequence.

Alteration Styles

Two distinct alteration styles are observed within the sedimentary units:

1. Thermal Recrystallization

• Produces bleaching and silicification
• Develops cherty textures in siltstone and sandstone
• Associated mudstone layers develop brownish tones
• Silt laminae form cherty stringers, enhancing bedding definition

This alteration is interpreted as a response to a nearby thermal event.

2. Metasomatic Alteration

• Characterized by introduction of new minerals, including:

  • Hematite (red)

  • Chlorite (green)

  • Biotite

  • Sericite (tan-yellow)

This alteration is typically associated with structurally deformed zones, particularly near faults and shear zones.

SUMMARY OF HYDROGEN RESULTS AND DATA INTEGRATION

Six geochemical domains were defined:

Domain 1 (4-86 m)

• Minor hydrogen results

• Limited structural influence

The dominant lithology within this interval is recrystallized siltstone, interbedded with sandstone and mudstone. These units are locally brecciated and exhibit crackle textures, with numerous calcite-quartz veinlets (<2 mm thick) occurring at various orientations relative to the core axis.

Recrystallized breccia is interpreted to be sedimentary in origin, containing cherty siltstone clasts up to 3 cm in size within a silica-rich matrix.

Several narrow fault zones containing gouge were identified at:

• 4.0-5.5 m

• 7.45-7.53 m

• 8.65 m (including a ~2 cm gouge zone)

Hydrogen concentrations in this interval are limited.

Although multiple shear zones are present, they appear to post-date the bleaching alteration, and gas samples collected in proximity to these structures are generally barren of hydrogen.

Additionally:

• CO is largely absent in this interval

• No consistent association between deformation features and gas enrichment is observed

Domain 2 (92-164 m) - KEY STRUCTURAL ZONE

Highlights:

• Includes major fault zones

• Hydrogen concentrations exceeding 1,000 ppmV

• Peak interval: 128-146 m

Lithology and Structural Setting

The upper fault is overlain by green-coloured, silicified siltstone that is strongly crackle-fractured, giving it a breccia-like appearance. The crackle fractures are altered to a pale grey colour and are crosscut by later quartz-filled veins.

The upper fault zone at 95-104.3 m, which consists of:

• Crushed rock and gouge

• Highly brecciated intervals (~20-30 cm wide)

• Broken siltstone and muddy sandstone blocks ranging from 20-60 cm near the top of the fault to up to 1.2 m near the lower contact

At the upper contact of the fault, irregular pinkish-orange carbonate veinlets overprint the green silicified unit.

At the lower contact (104.3 m), a highly altered, massive green micaceous unit is present. This unit is locally cut by irregular quartz blebs rimmed by dark minerals.

The micaceous unit is in contact with a grey sandy mudstone (wacke) containing angular to rounded quartz and lithic fragments (4-6 mm). Fractures within the wacke are lined with hematite.

Downhole Lithological Evolution

The grey wacke grades downhole into:

• Featureless green micaceous mudstone

• Thin conglomeratic intervals containing irregular white and dark grey lithic fragments, with less common pink granitic fragments

The interval is generally bleached and colour-banded, with green zones (~3 m thick) alternating with pale buff-grey or darker grey bands of similar thickness.

Local shear zones are present throughout.

Gas Geochemistry and Structural Association

At 90.1 m, adjacent to a narrow shear zone containing fault gouge oriented at shallow angles to the core axis, gas extracted from a drill water sample contained:

• Elevated hydrogen (>1,000 ppmV)

• Measurable CO

This shear cuts recrystallized, crackle-fractured siltstone overlying the upper fault at 95 m.

Within the main fault zone:

• Despite intense crushing and multiple shear intervals, the fault core itself shows limited alteration

• Gas samples from within the fault core are generally barren of hydrogen

However, at the base of the fault and within the underlying altered green micaceous mudstone, hydrogen concentrations increase:

• No detectable CO, O₂, or CH₄

Primary Hydrogen-Bearing Zone

The strongest hydrogen concentrations occur within the upper portion of the upper fault zone, between 128 and 146 m, where:

• Most sampled intervals returned measurable hydrogen

• Hydrogen concentrations in some samples exceeded 1,000 ppmV

Below this interval:

• Hydrogen values decrease but remain elevated

• CO remains absent

Lower Interval Observations

Below the Upper Fault zone the first sample to return an elevated hydrogen value occurred at 164 m depth.

This sample was collected from dark grey conglomeratic mudstone, associated with a 15 cm fault gouge zone at 163.4 m, and underlain by widely spaced (1-1.3 m) foliated conglomeratic intervals.

This marks the first appearance of foliation, characterized by:

• Flattened fragments aligned along foliation planes

• Foliation oriented at shallow angles (~20°) to the core axis

• Bedding typically oriented more steeply (~45° to core axis)

The conglomerate downhole becomes thinly bed with and passes into a green siltstone that contains a brownish grey mudstone bed ~20 cm thick. The green conglomeratic unit is silicified and bleached to a tan colour and underlain at 121m by a dark grey mudstone interval that again overlies a cobble conglomerate containing grain clasts up to 8 cm across.

Domain 3 (169-209 m)

Highlights:

• Foliated units with hydrogen measurements
• CO present, correlating with elevated hydrogen

Lithology and Structural Setting

This interval is underlain by grey to dark grey foliated mudstone conglomerate, containing granule- to cobble-sized fragments. These units are interbedded with occasional coarse-grained sandy mudstone beds (<1 m thick), which locally grade into cherty-textured recrystallized siltstone.

The conglomerates contain:

• Angular white and tan lithic fragments
• White quartz granules

These fragments are commonly flattened and aligned within foliation planes, forming narrow ribbons separated by dark laminated or mudstone layers (<10 mm thick).

Cobble-sized fragments include pink granitic clasts.

Foliation is well developed in intervals ranging from 25 to 50 cm thick, although shear zones are relatively rare within this domain.

Gas Geochemistry and Distribution

• Gas extracted from water samples within partially foliated intervals generally shows little to no hydrogen
• In contrast, samples collected from underlying, more consistently foliated units contain measurable hydrogen, with elevated values observed at:
  • 176-197 m
  • 212-230 m

Across this domain:

• All samples contain CO, ranging from 5 to 50 ppm
• Higher CO values (10-50 ppm) observed between 206 and 239 m are observed to coincide with elevated hydrogen concentrations

Figure 8: Foliated conglomeratic mudstone interbedded with more homogenous recrystallized muddy sandstone and siltstone. The fragments in the conglomerate range from cobble to granule size and range from white to pale grey to pink in colour. The pink fragments are granite in composition.

Appendix - Technical Reference: Summary of Sedimentary Sequence of DH-26-02

The sedimentary sequence consists of interbedded:

• Mudstone

• Siltstone

• Sandstone (grit)

• Conglomerate

These units display variable sorting, grain size, fragment composition, and matrix content.

Muddy and silty sandstone and conglomerate are generally matrix-supported, with framework grains composed of rounded to angular quartz, feldspar, and lithic fragments suspended in a clay-rich mudstone or cleaner siltstone matrix.

Lithic fragments typically include:

• Dark-coloured shale-like material

• Irregular silicified sandstone fragments

• Pink granitic fragments

Grain size varies across the sequence:

• Finer-grained sandstones tend to be more evenly sorted and lack clear bedding features

• Coarser-grained sandstones are often better sorted and may display thin (<2 cm) intervals of aligned quartz grains, giving a bedded appearance

These coarser units commonly grade into poorly sorted conglomerates, containing angular dark lithic fragments and, less frequently, rounded siliceous clasts within a mudstone or siltstone matrix.

Although some conglomeratic intervals exhibit a breccia-like appearance, they are interpreted as sedimentary due to their gradational transition into finer-grained, bedded units.

Mudstone and Bedding Features

Occasional dark mudstone beds, up to 30 cm thick and lacking visible bedding, occur within more siltstone-dominated intervals. These mudstone units represent a minor component (<3%) of the overall sequence.

In addition, thinly bedded to laminated intervals (1-5 cm thick) of alternating dark and light-coloured layers are observed. These reflect graded bedding, where:

• Coarser grains settle first

• Finer siltstone transitions upward into mud-rich layers

This pattern is characteristic of turbidite deposition.

Depositional Interpretation

The sedimentological characteristics described above are consistent with graywacke-wacke sequences comparable to those observed in:

• The Franciscan Formation (western California)

• Ordovician rocks of the Taconic orogen (Appalachian region)

These features are indicative of deposition within a turbidite-dominated foreland basin, where rapid erosion, transport, and burial of uplifted material occur during episodic tectonic activity.

Lithological Definitions and Sedimentological Characteristics

Mudstone is a detrital rock composed of silt-sized particles (5-64 microns; 0.005-0.06 mm) within a clay-rich matrix. It is typically massive and lacks visible bedding laminations or fissility.

Shale refers to a highly indurated, clay-rich mudstone characterized by:

• Well-developed fissility

• Finely stratified laminae (typically 0.1-0.4 mm thick)

• A cherty to hornfels-like texture

Argillite is a compact, weakly metamorphosed rock derived from mudstone, shale, or siltstone. It is more indurated than its parent material, generally massive in appearance, and typically lacks both bedding lamination and fissility.

Slate is a metamorphic rock derived from mudstone, shale, argillite, or volcanic ash. It is characterized by:

• Well-developed fissility planes

• Alignment of very fine-grained mica minerals (chlorite, biotite, and/or sericite)

• Foliation planes oriented independently of original bedding

These fissility planes are typically oriented perpendicular to the direction of maximum compressive stress.
