Toronto, Ontario--(Newsfile Corp. - May 15, 2026) - DiagnaMed Holdings Corp. (CSE: DMED) (OTCQB: DGNMF) ("DiagnaMed" or the "Company") announces that it has closed its previously announced (see press release of December 10, 2025) acquisition of the Colchester East Natural Hydrogen Project (the "Property"), consisting of 30 licenses totaling 2,104 claims located within the Cumberland Basin in Nova Scotia. Pursuant to the closing of the acquisition, the Company acquired the Property by paying: (i) $10,000 in cash; and (ii) issuing an aggregate of 10,000,000 common shares at an issue price of $0.06 per share, being the closing price of the common shares of the Company on the CSE on the date immediately preceding the closing date. The two arm's length vendors of the Property each received 5,000,000 common shares, which are subject to a statutory four-month-and-one-day hold period.

In addition, the vendors were granted a 2.0% gross revenue royalty on hydrogen, helium or any other mineral product sold from the Property. The Company may purchase, at its sole option, 50% of the Royalty at any time for $2,000,000. This strategic acquisition positions DiagnaMed directly within Canada's most active and rapidly expanding natural hydrogen corridor-a region that has seen increased exploration interest.

The acquisition also complements DiagnaMed's existing land position in Ontario's Temiscamingue hydrogen corridor and supports the Company's strategy to advance next-generation natural hydrogen extraction technologies.
