(TSXV: EVI) (OTCQB: EVIIF) (&#34;Eastport&#34; or the &#34;Company&#34;) is pleased to provide an update on its Phase 1 diamond drilling program at the 100%-owned Semarule Rare Earth Element (&#34;REE&#34;) Project (&#34;Semarule&#34; or the &#34;Project&#34;) in south-central Botswana.

Diamond drilling has tested the margins of both a gravity low (drill holes SEM006 &amp; SEM009) and a gravity high (drillholes SEM005 &amp; SEM007) (see Figure 1).

These holes are designed to better constrain the location and geometry of a potential carbonatite system.</li></ul>Burns Singh Tennent-Bhohi, CEO, commented, &#34;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&#34;<img src="https://imageproxy.pbkrs.com/https://images.newsfilecorp.com/files/8324/291754_89a019bc94c80b27_001.jpg?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="550" height="388" original-src="https://imageproxy.pbkrs.com/https://images.newsfilecorp.com/files/8324/291754_89a019bc94c80b27_001.jpg"/>Plan view of surface gravity anomaly.

Eastport Critical Metals Corp. (TSXV: EVI) has provided an update on its Phase 1 diamond drilling program at the Semarule Rare Earth Element Project in Botswana. The drilling has revealed promising signs of a carbonatite system, with significant geological features observed. The final two drill holes will target key areas to further assess the potential of the carbonatite system. CEO Burns Singh Tennent-Bhohi expressed optimism about the project's development and the upcoming results from the drilling program.
