QIMC Announces Major Natural Hydrogen Discovery in Nova Scotia with Multiple High-Grade Soil Gas Samples, Including Record 5,558 ppm

Montreal, Quebec--(Newsfile Corp. - August 25, 2025) - Quebec Innovative Materials Corp. (CSE: QIMC) (OTCQB: QIMCF) (FSE: 7FJ) ("QIMC" or the "Company") is pleased to report major results from its latest geochemical soil gas survey for its 1^st reported zone in Nova Scota, the West Advocate area of Cumberland Township. The program identified multiple high-concentration hydrogen anomalies, with over 65 soil gas samples exceeding 500 parts per million (ppm). Among these, 21 samples returned values above 1,000 ppm, highlighted by results of 2,047 ppm, 2,458 ppm, 2,885 ppm, and capped by the highest hydrogen soil gas concentration ever recorded by QIMC — 5,558 ppm.

"These multiple hydrogen soil gas results exceeding 1,000 ppm — including numerous samples above 2,000 ppm — represent a breakthrough for QIMC and the Canadian natural hydrogen sector," said John Karagiannidis, President of QIMC. "They validate our exploration model, confirm the region's natural hydrogen assets, and highlight the world-class expertise of our team."

Prof. Marc Richer-LaFlèche of INRS, who supervised the geochemical survey, added: "These concentrations are considered by the INRS team to be exceptionally high and currently unequalled in soils in Eastern Canada."

The discovery was made in proximity to the Cobequid Fault Zone, a major crustal-scale structure in the Canadian Maritimes that delineates the boundary between the Meguma terrane to the south and the Avalon terrane to the north. This fault system has undergone multiple episodes of reactivation throughout the Paleozoic and Mesozoic, reflecting a long and complex tectonothermal evolution. It is interpreted as an ancient rift zone, associated with episodes of volcanism and the emplacement of gabbroic and related mafic intrusions, which mark an early stage in the structural and magmatic development of this region. These characteristics make the Cobequid Fault Zone a highly prospective environment for natural hydrogen generation and migration.

Survey Highlights

• Highest value: 5,558 ppm H₂

• Geochemical survey conducted along Reid Family Forest Road and Eatonville Forest Road, covering more than 4 km each.

• 189 soil gas samples collected and analyzed in an INRS mobile laboratory.

• Samples were taken at 100m intervals using gas probes, an electric pump and one-liter gas sampling bags

• Stations showing concentrations of more than 1000 ppm were densified at 50m in order to better characterize the anomalous sectors

• A specific electrochemical detection system was used for the determination of H2

• This system has been calibrated using certified gas standards of 200, 500, 1000 and 20 000 ppm (H2)

• Hydrogen concentrations ranged from 0 ppm to 5,558 ppm.

  • 44 samples (23%) between 500-999 ppm

  • 11 samples (5.8%) between 1000-1499 ppm

  • 6 samples (3.2%) between 1500-1999 ppm

  • 3 samples between 2000-3000 ppm

  • 1 sample at 5,558 ppm

Following these results, QIMC has expanded its claim package in the West Advocate area to secure additional ground. The highest concentrations are observed in a spatial domain north of the Cobequid Fault and south of the Spicers Cove Fault. The rocks that make up the sedimentary rock cover are part of the Horton Gp (Carboniferous). The latter cover an older igneous basement made up of granitoids, gabbro and sedimentary rocks.

Corporate Update
QIMC is pleased to announce the following leadership update:

• Fabrice Consalvo has joined the Board of Directors. Mr. Consalvo is an accomplished energy executive with more than 30 years of experience spanning investment, corporate finance, business development, and operational performance. He has held senior leadership roles at Areva, Accenture, and Investissement Québec, and is currently the founder of Gamanergie Consulting, advising international companies on building efficient and profitable energy ecosystems.

• The Company has granted 1.7 million stock options at an exercise price of $0.25 per share.
