EASTPORT ANNOUNCES ADDITIONAL POSITIVE ASSAY RESULTS AT THE FOLEY URANIUM DISCOVERY

Eastport Critical Metals Corp. has released 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 May 28, 2026.

Burns Singh Tennent-Bhohi, chief executive officer, commented:

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

"Very encouragingly, these results confirm we are in the right rocks with the desired greater than 200 ppm U3O8 grade profile, with mineralization 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, stepout 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 mineralization 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 metres at 309.0 ppm (parts per million) U3O8 (triuranium octoxide) from 75.0 m;
• RC034: 6.0 m at 203.0 ppm U3O8 from 76.0 m, including 3.0 m at 273 ppm U3O8 from 76.0 m;
• RC037: 2.0 m at 241.5 ppm U3O8 from 43.0 m and 2.0 m at 450.0 ppm U3O8 from 54.0 m;
• Previously reported results from fence 1 (news release dated May 28, 2026):
  • RC006: 8.0 m at 553.0 ppm U3O8 from 84.0 m, including 2.0 m at 1,272 ppm U3O8 from 87.0 m;
  • RC003: 6.0 m at 500.7 ppm U3O8 from 92.0 m, including 3.0 m at 806 ppm U3O8 from 92.0 m;
  • RC005: 1.0 m at 2,333 ppm U3O8 from 103.0 m.

The fence 1 assay results demonstrate potential for widespread uranium mineralization (greater than 200 ppm U3O8), with significant, laterally continuous, uranium mineralization intersected in seven of the 16 drill holes.

The uranium mineralization 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, a project owned by Lotus Resources Ltd. According to publicly available disclosure by Lotus Resources, the Letlhakane project hosts a reported mineral resource estimate consisting of indicated mineral resources of 71.6 Mt (million tonnes) grading 360 ppm U3O8 for 56.8 Mlb (million pounds) contained U3O8, and inferred mineral resources of 70.6 Mt at 366 ppm U3O8 for 56.9 Mlb contained U3O8, based on a 200 ppm U3O8 cut-off grade.

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 $465-million (U.S.) and all-in sustaining costs ranging from $35 (U.S.) to $41 (U.S.) per pound U3O8.

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 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.

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 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 PGEs (platinum group elements) 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.
