Eastport Critical Metals intercepts 120m copper at NAK-East, extends strike 5km

Nak-East drilling intersects over 100 meters of copper mineralisation at its Flagship Matsitama Project

Copper mineralisation confirmed along the same geological structure as Nak-Main, highlighting the potential for significant exploration upside

Nak-West drilling, located 3 kilometres from Nak-Main, also intersects copper mineralisation, demonstrating the broader scale of the mineralised system

Vancouver, British Columbia--(Newsfile Corp. - August 4, 2026) - Eastport Critical Metals Corp. (TSXV: EVI) (OTCQB: EVIIF) ("Eastport" or the "Company") is pleased to announce the positive assay results from the step out drilling from the Phase 1 diamond drill program, completed as reported in the press release dated May 1, 2026 Link Here . The three holes drilled at Nak-East have identified a thick copper-rich mineralised zone approximately five kilometres east of the Nak-Main deposit, along key structural features which highlight the potential for substantial resource expansion. The two holes at Nak-West, approximately three kilometres west of Nak-Main are also mineralised, potentially representing a mineralised strike length of ten kilometres subject to future infill drilling.

Daniel Major, CEO, commented;

"These initial results from our recent drilling program are extremely encouraging. Historical exploration at the Matsitama Copper Project has indicated the potential for multiple exploration targets including the Nakalakwana (Main, East and West), Lepashe Copper Snake and Tholo areas. The three drill holes reported from Nak-East have long intersections of copper mineralisation while both holes drilled at Nak-West also report mineralised zones.

"The most exciting part of these excellent drilling results is the clear link between the copper mineralisation and key geological structures. This provides greater c
