Alpha drills 2.09 g/t Au over 12 m at New Aburna Corridor Obok

Calgary, Alberta--(Newsfile Corp. - September 21, 2026) - Alpha Exploration Ltd. (TSXV: ALEX) ("Alpha" or the "Company") is pleased to announce a first batch of results from its ongoing exploration drilling programme at the Aburna Gold Project. Core drill hole ABD029 has successfully intersected 12 metres grading 2.09 g/t gold within 31 metres grading 1.12 g/t gold which, coupled with other geological information and interpretation, advances this former exploration target to key prospect status. In addition, initial exploration drilling results at the EER and SW targets have returned multiple gold intercepts, demonstrating the potential to expand the Hill 52 prospect gold mineralization.

These new results relate to a total of 2,144.50 metres ("m"), including both core and reverse-circulation ("RC") drilling, from the early testing of four of seven new gold targets within the highly prospective Aburna corridor. In this gold corridor, Alpha has already discovered the Hill 52, Central and Northeast prospects, which host numerous shallow, high-grade gold intercepts.

The Aburna Gold Project is located within Alpha's 100% owned, 514 km² Kerkasha Project located in Eritrea. To date, only approximately 20 percent of the Aburna corridor, as defined by gold-in-soil anomalies, reconnaissance rotary air blast ("RAB") drilling in areas of immature, transported soil, and permissive geology and structure, has been tested by significant drilling. This fact linked with these new results emph
