Northern Discovery Metals Reports Progress on Stage 1 Exploration at the Vent Project

117 soil and 34 rock chip samples collected at the Vent Copper Project

CALGARY, Alberta, Sept. 22, 2026 (GLOBE NEWSWIRE) — Northern Discovery Metals Inc. (CSE: NOR) (FSE: M1V0) (“ Northern Discovery ” or the “ Company ”) is pleased to provide an update on its ongoing Stage 1 exploration program at the Vent Copper Project (“Vent” or the “Project”), located in the Alberni Mining Division on Vancouver Island, British Columbia. The field team has collected 117 soil samples and 34 rock chip samples to date as part of a program of geological mapping, prospecting and targeted sampling. The Company holds an option to acquire up to a 100% interest in the Project.

The work is being carried out by Geomap Exploration Inc. and follows the Company’s September 3, 2026 mobilization announcement. Stage 1 is designed to refine exploration priorities by examining the relationships between previously identified mineralization responses, geological contacts, structures, alteration and veining. The program was designed to initially focus on the Vent-Ken and Sentinel Peak areas and includes ground checks of priority magnetic and VLF-EM features.

Fieldwork to date has included systematic soil sampling and the examination and sampling of selected rock exposures. Preliminary field descriptions include volcanic and intrusive rocks, with localized chlorite alteration, quartz veining and minor pyrite noted at selected rock sampling sites. These observations will help inform the geological interpretation of the sampling results. Laboratory analysis is required to determine the potential for any metal content, and no assay results from the current program are reported in this release.

“The field team is building the geological and geochemical dataset we need to guide the next stage of exploration at Vent,” said Jared Suchan, Ph.D., P.Geo., Chief Executive Officer and Director of Northern Discovery Metals. “Our priority is to bring the sampling, geological observations and existing geophysical information together to identify where more detailed follow-up is warranted. This systematic approach will help us direct future work toward the strongest targets.”

Jared Suchan, Ph.D., P.Geo., Chief Executive Officer and Director of the Company, and a “Qualified Person” within the meaning of National Instrument 43-101 – Standards of Disclosure for Mineral Projects, has reviewed and approved the scientific and technical contents of this news release.
