Appia Identifies Several Additional Uranium Drill Targets from MT Survey Lines 1 and 3 at Its Otherside Uranium Property

(CSE: API) (OTCQB: APAAF) Appia Rare Earths & Uranium Corp. announced that final interpretation of Lines 1 and 3 from its Q1 2026 SPARTAN Magnetotelluric (MT) survey has outlined several additional preliminary drill targets for potential uranium mineralization at its 100%-owned Otherside Uranium Property in Saskatchewan's Athabasca Basin. The priority targets include P-02, P-04, and P-06 on Line 1, and P-13, P-14, and P-15 on Line 3, forming part of a broader 16-target inventory that also includes previously identified Line 2 targets P-09, P-09a, and P-10. Line 1 returned features such as an interpreted offset in the unconformity near the south end of the profile, a strong conductor at the south end, and a historical ZTEM anomaly indicating a possible deeper conductive body within the basement. Line 3 identified evidence of disruption within the sandstone above the unconformity, ZTEM anomalies responding to shallower conductive features, increased conductivity and density in the sandstone, and MT conductors in the sandstone above the unconformity at P-14 and P-15. Appia plans a tight-spaced, high-resolution ground MT 3D grid and Ambient Noise Tomography (ANT) surveys over the Line 2 priority corridor to further evaluate an ingress/egress exploration model based on interpreted geophysical similarities to McArthur River. The resulting model will refine the main conductor break and local structural setting before drilling, with the company aiming to advance the highest-priority targets to precision diamond drilling in 2027. The Otherside Property area is 15,146.129 hectares and is 100% owned by Appia. Appia holds a 25% interest in Ultra Rare Earth Inc., and Ultra USA indirectly holds a 100% interest in the Ultra Hard Rock and Ultra IAC Projects, totaling 42,932.24 ha. in Goiás, Brazil. Appia holds the surface rights to exploration for 101,692.35 hectares (251,287.27 acres) in Saskatchewan and has a 100% interest in 14,483 hectares (35,788 acres) with rare earth elements and uranium deposits over five mineralized zones in the Elliot Lake Camp, Ontario. Appia has 194.9 million common shares outstanding and 206.6 million shares fully diluted.
