Vancouver, June 9, 2026 - Eastport Critical Metals Corp. (TSXV: EVI) (OTCQB: EVIIF) ("Eastport" or the "Company") is pleased to announce the second batch of laboratory assay results for the reverse circulation (RC) drilling program at the Foley Uranium Project in Botswana. The second batch covers the results for the final five of 16 drill holes located on drill Fence 1, the first batch of assay results were announced 28 May 2026.

CEO, Burns Singh Tennent-Bhohi, commented:

"The latest batch of assays at Foley complete the results for drill Fence 1, which shows significant uranium mineralisation over a full 1.4 kilometres of strike length.

Very encouragingly, these results confirm we are in the right rocks with the desired >200ppm U₃O₈ grade profile, with mineralisation remaining open to the north, south and east.

Whilst we still await the assay results for drill Fence 2, the Fence 1 results already warrant the commencement of additional drill fences, step-out drilling, and targeted geophysics to extend coverage to the north and east and to vector towards the key geological controls. By systematically mapping where the mineralisation thickens, enriches, or pinches out, we aim to rapidly unlock the true size potential of this exciting new uranium discovery in Botswana."

Highlight Drill Hole Intersections (depth stated downhole):

• RC033: 5.0 m @ 309.0 ppm U₃O₈ from 75.0 m

• RC034: 6.0 m @ 203.0 ppm U₃O₈ from 76.0 m, including 3.0 m @ 273 ppm U₃O₈ from 76.0 m.

• RC037: 2.0 m @ 241.5 ppm U₃O₈ from 43.0 m and 2.0 m @ 450.0 ppm U₃O₈ from 54.0 m.

• Previously reported results from Fence 1 (news release, 28 May 2026, link here):

  • RC006: 8.0 m @ 553.0 ppm U₃O₈ from 84.0 m, including 2.0 m @ 1,272 ppm U₃O₈ from 87.0 m.

  • RC003: 6.0 m @ 500.7 ppm U₃O₈ from 92.0 m, including 3.0 m @ 806 ppm U₃O₈ from 92.0 m.

  • RC005: 1.0 m @ 2,333 ppm U₃O₈ from 103.0 m.

The Fence 1 assay results demonstrate potential for widespread uranium mineralisation (>200ppm U₃O₈), with significant, laterally continuous, uranium mineralisation intersected in 7 of the 16 drill holes (see the Figure 1 plan and cross section).

The uranium mineralisation which remains open both along strike and dip, is hosted in Karoo Supergroup sediments in an interpreted paleo-channel setting.

The reported drill Fence 1 is located approximately 350 metres north of the Letlhakane deposit (Figure 2), a project owned by Lotus Resources Ltd.. According to publicly available disclosure by Lotus Resources Limited, the Letlhakane project hosts a reported Mineral Resource Estimate consisting of Indicated Mineral Resources of 71.6Mt grading 360 ppm U₃O₈ for 56.8 Mlb contained U₃O₈, and Inferred Mineral Resources of 70.6Mt at 366 ppm U₃O₈ for 56.9 Mlb contained U₃O₈, based on a 200ppm U₃O₈ cut-off grade.¹

Furthermore, Lotus Resources concluded a Scoping Study for the Letlhakane Uranium deposit in 2025. The study outlined a 10-year open-pit mining operation producing approximately 3.0 million pounds of U₃O₈ annually, with estimated initial capital costs of US$465 million and all-in sustaining costs ranging from US$35 to US$41 per pound U₃O₈.²

The Company advises that mineralization hosted on adjacent, nearby or geologically similar properties, including the Letlhakane Project, is not necessarily indicative of mineralization on the Foley Project. The historical and technical information regarding the Letlhakane project has been sourced from publicly available disclosure by Lotus Resources Limited and has not been independently verified by the Company's Qualified Person.

Pressed Pellet Assay Technique

Sample preparation and analytical work is conducted by SGS Group, an accredited laboratory based in Johannesburg, South Africa. Samples are weighted, dried, crushed, riffle split, and pulverized to a nominal pulp size suitable for pressed pellet analysis. Uranium and thorium are analyzed using a WD-X-ray fluorescence ("XRF") Spectrometer technique.

For the pressed pellet method (SGS analytical method code GE_XRF71UTH), a representative portion of pulverized sample is blended with a binding agent and compressed under high pressure to produce a homogeneous pellet for instrumental analysis. The prepared pellets are analyzed by XRF spectrometry to determine uranium and thorium concentrations, with certificated results for U, Th, U₃O₈ and ThO₂.

Eastport implements quality assurance and quality control ("QA/QC") procedures including the routine insertion of blanks, and duplicate samples within the analytical stream. SGS also applies internal laboratory QA/QC protocols in accordance with their standard operating procedures.
