Eastport Expands Drilling Program at Foley

Uranium Project in Botswana Following

Completion of Phase 1 Drill Program

Vancouver, British Columbia--(Newsfile Corp. - March 12, 2026) -

Eastport Critical Minerals

Corp.

(

TSXV: EVI) (OTCQB: EVIIF

) ("Eastport" or the "Company") is pleased to provide an update on

its ongoing exploration activities at the Foley Uranium Project, located immediately north of the

Letlhakane uranium deposit in Botswana's Central District, one of the largest undeveloped Uranium

deposits in the world.

Highlights:

Initial drilling fences, spanning approximately 3.5 kilometres

in width, have revealed

consistent radioactive anomalies that remain open-ended, prompting a strategic shift to wider-

spaced drilling to delineate the system's potential boundaries [

see figure 1

]

The Company is fast-tracking Phase 2 exploration

by increasing drill spacing to 1-kilometer

centres along strike, aiming to constrain the edges of mineralization and define a district-scale

exploration target. [

see figure 2

]

Encouraging gamma logging results

from the first three fences have exceeded the team's

expectations, supporting accelerated efforts to explore the broader uranium-hosting potential in the

shallow Karoo sediments.

Eastport's RC (reverse circulation) drilling program focuses on sampling the unconformable Karoo

sediments overlying the basement, using gamma logging and handheld spectrometers to identify

uranium-bearing horizons. While the Foley Project was initially targeted for uranium mineralization within

paleo-channel features [ancient river-like pathways etched into the basement rocks] recent drilling has

indicated a more extensive system. This evolving interpretation aligns with a "uranium wash" model,

where mineral-rich fluids have potentially infiltrated broader sedimentary layers, similar to sheet-like

dissemination observed in other regional deposits.

The completed drill fences have shown persistent gamma radiation signals across multiple holes drilled

on 200m and 400m spacing.

Anomalous gamma readings were measured at or above the basement

contact across a 3.5km strike on both fences suggesting the mineralization extends beyond initial

assumptions without yet encountering defined edges. This has led to the decision to expand spacing in

Phase 2, vectoring toward a compliant exploration target once the system's lateral extents are better

understood.

"These early indicators are highly motivating," said Burns Singh Tennent-Bhohi, CEO of Eastport. "What

started as a channel hunt now points to something much larger, similar to discovering a vast floodplain

instead of a single stream. We're prioritizing edge definition to unlock Foley's full potential to accelerate

the establishment of a compliant exploration target."

Foley Project Location

The Foley Uranium Project (PL113/2020) is located approximately 75 km south of Francistown in the

Central District of Botswana, directly abutting the Lotus Resources' licences that hosts their world-scale

Letlhakane Uranium Deposit, one of the world's largest undeveloped uranium resources. Positioned

along the proven Karoo palaeo-channel fairway, the project enjoys excellent infrastructure, including

sealed highway access via the A14, close proximity to the national power grid, abundant groundwater for

processing, and ready availability of drilling contractors, equipment, and skilled labour from nearby

mining hubs.

Qualified Person

The information in this news release has been reviewed and approved by Liz de Klerk

Pri.Sci.Nat.,FIMMM, of Micon International, an independent consultant of the Company and Qualified

Persons as that term is defined in National Instrument 43-101.

Assays from the initial drilling are pending, and the Company cautions that gamma data alone does not

confirm economic mineralization. Phase 2 drilling is scheduled to commence in the Q2, and the

Company will provide further updates upon commencement.

All exploration activities are conducted in

compliance with NI 43-101 standards, with results subject to verification by qualified persons.

About Eastport Ventures Inc.

Eastport Ventures is a disruptive 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 sizeable 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 PGE's 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 per capita with a 50-year track 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 activity in the natural resources sector in recent years.
