APPIA UNVEILS PROMISING DRILL TARGETS AT OTHERSIDE PROPERTY, MIRRORING GEOPHYSICAL TRAITS OF NEXGEN'S "ARROW" AND PALADIN ENERGY'S "TRIPLE R" DEPOSITS, ATHABASCA BASIN, SASKATCHEWAN, CANADA

Appia Rare Earths & Uranium Corp. has identified multiple high-priority drill targets at its Otherside property in the Athabasca basin, Saskatchewan, following the conclusion of the recent airborne gravity gradiometer (AGG) and magnetometer survey. These targets exhibit geophysical signatures comparable with those of NexGen Energy's Arrow and Paladin Energy's Triple R high-grade uranium deposits, suggesting Otherside's potential for a significant discovery.

Tom Drivas, chief executive officer of Appia, commented: "The encouraging outcomes of our recent survey outline the course for our exploration initiatives at the Otherside property this year. Our goal is to lead the discovery of high-grade uranium deposits in the less explored north-central regions of the Athabasca basin, targeting areas that exhibit geophysical signatures similar to those found at NexGen's 'Arrow' and Paladin Energy's 'Triple R,' high-grade uranium deposits."

Highlights

• High-priority drill targets identified: The survey revealed multiple targets with geophysical signatures comparable with NexGen's Arrow and Paladin Energy's Triple R deposits.
• Promising geophysical anomalies: Targets are associated with gravity lows, magnetic lows and a 49-kilometre-long electromagnetic (EM) conductor with variable offsets and bends -- key indicators for potential uranium mineralization.
• 2025 exploration program: Appia's exploration plans include advanced 3D processing and potential ground geophysical surveys to refine drill target locations.
• Strategic location: The Otherside property is situated in the Athabasca basin, home to some of the world's highest-grade uranium deposits.

Detailed overview

2025 exploration plans

Appia's 2025 exploration program will focus on the high-priority targets identified in the survey. The company plans to conduct advanced 3-D processing and ground geophysical surveys to further refine these targets and maximize the success of a future drilling program. On-site exploration is planned in collaboration with the Fond du Lac First Nations to co-ordinate local accommodations and crew staffing.

Similarities to NexGen's Arrow and Paladin's Triple R

The Otherside property shares critical geophysical characteristics with the Arrow and Triple R deposits, including:

• A 49 km long EM conductor with variable offsets and bends;
• Gravity low and magnetic low anomalies along the conductor's strike length;
• Structural complexities such as shear zones, faults and reactivations, which are essential for uranium deposition.

Formation of uranium deposits in the Athabasca basin

Unconformity uranium deposits in the Athabasca basin form when oxidizing fluids circulate, dissolve uranium-bearing minerals/rocks and later precipitate uranium at the unconformity due to chemical changes caused by the interaction with reduced fluids, gases or rocks. These deposits are often controlled by reactivated fault systems, which create structural-geochemical traps for uranium mineralization.

Geophysical tools guiding exploration

Appia's exploration strategy utilizes gravity, magnetics and electromagnetics (EM) to identify uranium mineralization:

• Gravity and electromagnetics (EM): Gravity low anomalies indicate less dense, altered minerals, while EM conductors highlight fluid pathways often associated with uranium deposits.
• Magnetics: Magnetic low anomalies suggest the presence of non-magnetic materials like clay minerals or altered rocks, commonly found in alteration halos around uranium mineralization.

About the Otherside project

The Otherside project 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 property shares similar geological and geophysical signatures to known high-grade, large-tonnage uranium deposits in the western Athabasca basin, including Fission Uranium Corp.'s Triple R and NexGen Energy's Arrow deposits. Such signatures include long structural corridors hosting multiple, discrete conductors with associated magnetic gradients and gravity low areas.

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