EASTPORT CRITICAL METALS ANNOUNCES SELEBI-EAST PROJECT UPDATE AND APPOINTMENT OF GLOBAL ONE MEDIA

Eastport Critical Metals Corp. launched the phase II geochemistry and geophysical exploration program at the Selebi-East project prospective for nickel, copper and platinum group elements (PGE), in northeastern Botswana. The program builds on existing soil anomalies and untested conductors in the same geological domain as the nearby Selebi mine operated by NexMetals Mining Corp.

Selebi-East phase II exploration program highlights:

• Geochemical soil sampling grid expansion: over 325 new samples planned to infill and extend targets located within licence areas PL001, PL003 and PL2183, extending over favourable mafic/ultramafic units with known copper-nickel responses;
• Electromagnetic geophysics: priority ground electromagnetic (EM) geophysical survey designed to test a large, untested airborne conductor with a coincident soil anomaly on the steep west-dipping limb of a fold, marginal to a newly defined nickel-copper-zinc soil anomaly. Two additional survey grids will test soil anomalies on PL004 and PL2183. The three survey grids are planned with a 100-metre line spacing. Further survey parameters will be detailed in due course;
• Gravity geophysics: integrated gravity geophysics survey over EM targets. The gravity survey will be calibrated against the density values measured at the nearby Selebi mine massive sulphide deposits, to prioritize EM conductive targets and optimize drill collar planning;
• Clear path to drilling: phase II program is designed to generate drill-ready targets on three EM grids. The company completed the required environmental impact assessment (EIA) in Q1 (first quarter) 2026.

Further program details:

The Selebi-East program has mobilized. Full analytical results and geophysical reporting are expected within two-three months, positioning Eastport to define maiden drill collars on multiple high-priority targets.

Eastport's technical team has already mapped mafic/ultramafic lithologies coincident with soil anomalies on PL002 and PL004, confirming the similar stratigraphic and structural setting that hosts nickel-copper sulphide mineralization at Selebi. The planned ground EM will provide the depth resolution needed to test the downdip conductor. Gravity data will further derisk targets by highlighting dense bodies analogous to known Selebi-style mineralization.

Burns Singh Tennent-Bhohi commented: "We are maintaining aggressive momentum across our critical metal's portfolio during this high-intensity phase for Eastport. Despite market volatility, we remain engaged and motivated by the progress at our projects and the clear signs that we are still in the early innings of a powerful resurgence in discovery-driven mineral assets.

"Rising inflationary pressures, looming supply constraints and the growing imperative for secure supply chains are compelling global capital to seek out stable jurisdictions and high-quality exploration opportunities like those we hold in Botswana, recently voted No. 2 in the Fraser Institute Policy and Perception Index.

At Selebi-East, the company's focused campaign, combining targeted soil geochemistry with deep-penetrating ground EM and gravity, perfectly illustrates the company's strategy: leverage proven geology in the same belt as the neighbouring Selebi mines, use existing infrastructure and maintain a clear timeline to generate drill-ready targets. We are excited to unlock the next chapter of nickel-copper-PGE potential right next door to an active nickel-copper camp."

About Eastport Critical Metals Corp.

Eastport is a critical minerals development company advancing five projects in Botswana, with cumulative historical and current expenditures approaching $20-million. The company's most advanced asset is the Matsitama copper project, which hosts multiple sizable targets across the Matsitama copper district.

The company's additional projects include Selebi East, a nickel-copper-cobalt project located seven kilometres east of the historic Selebi mines; the Semarule rare earth elements project, positioned within the Gaborone-Molepolole corridor; the Foley uranium project, adjoining the Letlhakane uranium deposit; and the Keng project, which targets nickel, copper and PGEs on the northern margin of the Molopo Farms complex.

Botswana is widely regarded as one of Africa's strongest mining jurisdictions, combining the continent's highest GDP (gross domestic product) per capita with a 50-year record of large-scale mineral development since the Orapa diamond discovery in 1967. The country ranks among the top performers globally on the Fraser Institute's Investment Attractiveness Index and is the highest-rated jurisdiction in Africa on the Policy Perception Index. These rankings reflect Botswana's stable regulatory environment, consistent rule of law and long-standing support for responsible mineral development -- factors that have underpinned significant investment and major M&A (merger and acquisition) activity in the natural resources sector in recent years.
