QIMC Confirms Fourth Major Natural Hydrogen Zone in Nova Scotia with Soil-Gas Results up to 4,850 ppm - 2 km Continuous Anomaly Along Windsor-Cumberland Fault
Montreal, Quebec--(Newsfile Corp. - October 1, 2025) - Quebec Innovative Materials Corp. (CSE: QIMC) (OTCQB: QIMCF) (FSE: 7FJ) ("QIMC" or the "Company") is pleased to announce the confirmation of a fourth major natural hydrogen zone in Nova Scotia, highlighted by a peak soil-gas concentration of 4,850 ppm. The newly identified zone, located in the Little Forks-Springhill area, highlights a restricted geological context where source, reservoir, and barrier conditions combine to create a 2 km continuous expression of hydrogen along the boundary fault separating the Windsor Group from the Cumberland Group.

The analytical program returned over 24 readings above 500 ppm, four results between 1,500-1,999 ppm, two results between 2,000-2,999 ppm, and a high of 4,850 ppm — confirming the exceptional strength and extent of this anomaly.

This breakthrough further demonstrates the remarkable scale of hydrogen anomalies in Nova Scotia, adding to QIMC's three previously announced discoveries. With the identification of two principal hydrogen corridors on both sides of the Cumberland Basin, one in the East and one in the West of the province, separated by only a 1 hour 15 drive, this further demonstrates the regional scale necessary to support the development of a clean ammonia production hub.

"This fourth discovery validates our exploration thesis: Nova Scotia possesses the right geological conditions faulted and folded reservoirs, sealed by impermeable evaporites that can host large-scale natural hydrogen accumulations," said John Karagiannidis, President & CEO of QIMC. "With hydrogen zones confirmed on both sides of the Cumberland corridor, we are looking at the foundations of a regional development model, including ammonia production, built on multiple high-potential corridors."

The QIMC and INRS teams will be returning to Nova Scotia on October 5, 2025, to begin the next phases of development.

DiagnaMed Launches Ontario Hydrogen Exploration Campaign in Conjunction with QIMC and INRS; Strengthens Board
Toronto, Ontario--(Newsfile Corp. - July 3, 2025) - DiagnaMed Holdings Corp. (CSE: DMED) ("DiagnaMed" or the "Company"), is pleased to announce it has signed an agreement with the Institut national de la recherche scientifique (INRS) to initiate a comprehensive hydrogen exploration campaign on its Ontario properties, in conjunction with Quebec Innovative Materials Corp. (CSE: QIMC) ("QIMC"). The exploration will be led by Dr. Marc Richer-Laflèche and will include collaboration with members of the Temiscamingue First Nations. Leveraging the innovative geological exploration model successfully developed and deployed by INRS and QIMC at St-Bruno-de-Guigues, Quebec, the Ontario program will include an extensive campaign of over 2,000 soil gas samples aimed at identifying high-potential natural hydrogen zones.
