Eastport Reports 110.8m at 0.43% Cu at Nak-Main and Launches 291 km2 Gravity Survey at 30km Thole-Copper Snake Copper in Soil Anomaly

Eastport Critical Metals Corp. has released final assay results from Phase 1 drilling at the Nakalakwana (Nak-Main) area of its Matsitama Copper Project in Botswana. The company also initiated a 291 km² gravity geophysical survey across the 30 km Thole to Copper Snake soil anomaly to identify dense rock and deeper structures, with future magnetotelluric (MT) surveys planned to map subsurface conductivity.

Key drill intersections included:

• Hole NAKDD25-006 intersected 110.8 m @ 0.43% Cu from 123.6 m, including higher-grade intervals capped at 1% Cu.
• Hole NAKDD26-012 reported 16.0 m @ 0.52% Cu from 63.3 m.
• Hole NAKDD25-001 reported 41.0 m @ 0.27% Cu from 60.9 m.
• Hole NAKDD26-005 reported anomalous copper assays from 137.7 m.

The explored footprint currently represents less than 1% of the 1,845 km² license area. Eastport Critical Metals Corp. aims to use these datasets to qualify existing resources under NI 43-101 standards and target future infill drilling. Historical data from SRK Consulting (2013) cited a resource of 9.9 Mt @ 4,640 ppm Cu, though this is explicitly noted as not current NI 43-101 compliant.

Eastport Critical Metals Corp. (EVI) released a follow-up to its July 2026 drill results, confirming the continuity of mineralization rather than identifying a high-grade discovery. The reported average grades of 0.43% Cu are considered sub-economic for typical open-pit operations without bulk tonnage or significant processing advantages. The intersection includes overlimit samples capped at 1% Cu and dilution sections, such as a 2.37m unsampled section at 0% Cu, which underscores the low-grade nature of the findings.

Additionally, the company conducted a gravity survey, an early-stage exploration tool with no immediate financial or valuation impact. This update aligns with previous expectations for resource definition work and does not alter the company's near-term catalysts or capital requirements. Market reaction has been muted, reflecting the incremental nature of the update and the ongoing focus on low-grade intersections.

Eastport Critical Metals Corp. (EVI) is a pre-revenue junior explorer focused on critical metals in Botswana. Its flagship Matsitama Copper Project encompasses approximately 1,845 km² across six Prospecting Licenses, located roughly 85 km west of Francistown.

Key targets within the portfolio include Nak-Main (copper), Copper-Cobra (IOCG potential), Kopano South, Semarule REE, Foley Uranium, and Selebi-East Ni-Cu. The company is pursuing a "Develop and Distribute" model, aiming to retain economic interest while reducing balance-sheet exposure through secondary listings and strategic partnerships.

Daniel Major was appointed CEO effective July 1, 2026, replacing Burns Singh Tennent-Bhohi.
