Eastport Critical Metals Corp. (TSX-V: EVI) (OTCQB: EVIIF) is pleased to announce that drilling at Foley has now confirmed shallow, continuous uranium mineralisation across two parallel fences spaced approximately 400 m apart, each covering a strike length of over 1.4 km and located only 350–750 m north of Lotus Resources’ Letlhakane deposit. Multiple holes on both fences returned intercepts well above the 200 ppm U₃O₈ cut-off used in Letlhakane’s resource model, including attractive high-grade internal zones. These results support a coherent Letlhakane-style paleo-channel uranium system in Karoo Supergroup sediments that remains wide open along strike and down-dip, highlighting significant district-scale potential on Eastport’s ground.

The results, obtained using the pressed pellet analytical technique, demonstrate potential for large-scale uranium mineralisation (>200ppm U₃O₈), with uranium intersected in 4 holes on drill Fence 2.

Drill Fence 2 Highlight Downhole Intersections:

• RC012: 3.0 m @ 284.7 ppm U₃O₈ from 84.0 m.
• RC013: 2.0 m @ 260.5 ppm U₃O₈ from 100.0 m.
• RC016: 6.0 m @ 363.4 ppm U₃O₈ from 60.0 m, including 1.0 m @ 1,319 ppm U₃O₈ at 63.0m.
• RC018: 1.0 m @ 416.0 ppm U₃O₈ from 49.0 m and 1.0 m @ 325.0 ppm U₃O₈ at 54.0 m and 1.0 m @ 530.0 ppm U₃O₈ at 58.0m.

The reported drill Fence 2 is located approximately 400m north of drill Fence 1 (see news release 9 June 2026 here) and approximately 750 metres north of the Letlhakane deposit (Figure 1), a project owned by Lotus Resources Limited, hosting a reported Mineral Resource 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 200pm U₃O₈ cut-off grade.¹

CEO, Burns Singh Tennent-Bhohi commented, “Completing both Fence 1 and Fence 2 with consistent uranium mineralisation represent strong early success for our maiden drill campaign at Foley. We have now traced the same shallow paleo-channel horizon across more than 1.4 km of strike and 400 m of width, less than 1km North of Lotus Resources’ Letlhakane deposit.

“The continuity between fences, grades above the 200 ppm cut-off, and presence of high-grade lenses are highly encouraging and continue to support our geological model. The system remains open in all directions, giving us a clear and exciting pathway to test scale and grade. Our next steps will focus on additional fences, step-out drilling, and geophysical vectoring to map the geological controls and define where the mineralisation thickens or enriches.”

Uranium mineralisation is hosted in Karoo Supergroup sediments in a classic paleo-channel setting and remains open.

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 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 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.

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.
