Eastport Provides Semarule-REE Drilling

Update

Vancouver, British Columbia--(Newsfile Corp. - April 9, 2026) - Eastport Critical Metals Corp. (TSXV:

EVI) (OTCQB: EVIIF) ("Eastport" or the "Company") is pleased to provide an update on its Phase 1

diamond drilling program at the 100%-owned Semarule Rare Earth Element ("REE") Project

("Semarule" or the "Project") in south-central Botswana. Semarule is located approximately 27km north-

west of the Capital city, Gaborone.

Highlights

Diamond Core Drilling has intersected highly encouraging visual indicators suggesting

the presence of a carbonatite system

, including fenite alteration, thick calcite veining, and

extensive mafic-rich intervals.

Ground gravity survey over the

Semarule Igneous Complex

supports the thesis of a sub-

surface carbonatite.

Diamond drilling has tested the margins of both a gravity low (drill holes

SEM006 & SEM009) and a gravity high (drillholes SEM005 & SEM007) (see Figure 1). These

geophysical features are commonly associated with carbonatite deposits in Africa (e.g., Songwe

Hill and Kangankunde).

Wide-spread surface bedrock sampling continues

across the Semarule Hill syenite. Samples

are planned for use in a mineral study.

An independent mineralogical and metallurgical study

of REE hosting syenite rock samples

from the Semarule Igneous Complex is planned, to determine REE deportment, REE recovery

potential, and whether near surface syenite material could support a saleable product.

The final two holes of the Phase 1 program

, SEM007 (underway) and SEM009, will target the

centre of the gravity high and gravity low respectively (see Figure 1). These holes are designed to

better constrain the location and geometry of a potential carbonatite system.

Burns Singh Tennent-Bhohi, CEO, commented,

"

What started as a surface syenite target with rare earth anomalies has quickly developed into two

clear, high-potential targets at Semarule: an at-surface syenite intrusion that we are preparing to fast-

track through a detailed mineralogical and metallurgical study, and a subsurface carbonatite

opportunity supported by strong visual drilling results and the recently completed gravity survey.

The final two holes of Phase 1 will directly test the centres of the gravity low and the gravity high.

These holes are critical steps toward vectoring in on and constraining the potential for a carbonatite

system. We look forward to reporting results as soon as they become available"

Gravity Survey Parameters

Exploration Geophysics Pty Ltd., completed a reconnaissance ground gravity survey over a 4 x 4km

block overlying the Semarule Igneous Complex (SIC), located within Eastport Ventures Botswana's

license number PL2480/2023 near Molepolole, Botswana.

The reconnaissance gravity survey was conducted using the following parameters:

Station spacing: 500 m

Line spacing: 500 m

This survey was aimed at delineating targets for Rare Earth Elements (REE) and any other minerals. The

surveys were conducted between 19th and 26th February 2026. A total of 80 gravity stations over

approximately 5600Ha were surveyed.

About Eastport Critical Metals Corp. (TSXV: EVI) (OTCQB: EVIIF)

Eastport is a critical minerals development company advancing five projects in Botswana, with

cumulative historical and current expenditures approaching CAD$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.
