Appia to Initiate Magnetotelluric (MT) Survey at the Otherside Uranium Property, Targeting Uranium-Prospective EM Conductor

Toronto, Ontario--(Newsfile Corp. - January 20, 2026) - Appia Rare Earths & Uranium Corp. (CSE:API) (OTCQB:APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") is pleased to announce that it has engaged Quantec Geoscience Ltd. ("Quantec") to complete a SPARTAN Magnetotelluric ("MT") survey in Q1 2026 on the Company's 100%-owned Otherside Uranium Property (Figure 1) in Saskatchewan's renowned Athabasca Basin. The 10,422-hectare property is located approximately 28 km south of Fond-du-Lac, Saskatchewan.

Appia has identified a 49 km long, faulted EM conductor trend that is potentially prospective for Athabasca-style uranium mineralization and comparable to features associated with NexGen Energy's Arrow deposit, one of the world's largest high-grade uranium discoveries.

The MT survey (Figure 1) will be integrated with Appia's 2024 airborne gravity and magnetic data and several other datasets to confirm drill-ready targets by:

• Mapping subsurface resistivity to identify key faults and conductive zones
• Highlighting density contrasts indicative of alteration and structure
• Outlining lithological variations and basement trends

Tom Drivas, President of Appia, commented:
"The MT survey will provide the final major dataset needed to define high-confidence drill targets along this extensive 49 km long conductor, advancing our planning toward the next phase of drilling."

Survey Details:

84 MT stations spaced 200 metres apart, ~17 days fieldwork, with daily progress reports, including preliminary 2D inversion sections.

About Appia's Otherside Uranium Property

Appia's Otherside Uranium Property is strategically located within the prolific, uranium-bearing Athabasca Basin of Saskatchewan, Canada. This area is renowned for its significant uranium deposits, its surrounding rare earth element plays, and favorable geological conditions that have historically led to major high-grade uranium discoveries.

The Otherside Uranium Property shares similar geological and geophysical signatures to known high-grade, large-tonnage uranium deposits in the western and eastern Athabasca Basin, including Uranium Energy Corp.'s "Shea Creek" and Cameco's "Millenium" deposits. Such signatures include long structural corridors hosting multiple, discrete conductors associated with the Athabasca Basin's unconformity.

Otherside's property area is 10,441.88 hectares and is 100% owned by Appia.
