Appia Plans a 3,300 Metre Summer Drill Program at the Alces Lake Rare Earth Elements Property

Toronto, Ontario--(Newsfile Corp. - April 29, 2026) - Appia Rare Earths & Uranium Corp. (CSE:API) (OTCQB:APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") is pleased to provide an update on its Alces Lake Rare Earth Elements (REE) Property in northern Saskatchewan, where the Company has finalized its exploration plans, logistics, and contractor arrangements for an approximately 3,300-metre, 9-hole diamond drill program, with mobilization scheduled to begin on or about May 29, 2026.

The upcoming drill program is designed to test high-priority REE targets identified from Appia's recently announced 2025 ground gravity survey results at Alces Lake. The 2025 results refined and strengthened several target areas first outlined by the 2024 Airborne Gravity Gradiometer survey, with Targets 1, 5, 6, and 7 emerging as first-order priorities.

Targets 1 through 7 were prioritized based on geophysical similarities to the high-grade WRCB zone and the large, near-surface Magnet Ridge zone. Appia intends to test these targets for the potential continuation of REE-mineralized lithological packages at depth and along strike the regional northwest-southeast structural corridor, the same corridor that hosts the property's prolific WRCB and Magnet Ridge zones.

Tom Drivas, CEO and Director of Appia, commented:

"Following the successful identification of several high-priority drill targets at Alces Lake, we are excited to move forward with our approximate 3,300-metre drill program this summer. With logistics now finalized, Appia is ready to take the next step in advancing the broader potential of the Alces Lake REE Property by drill testing targets at depths of approximately 300 to 500 metres that exhibit compelling geophysical similarities to the surface and near-surface WRCB and Magnet Ridge mineralized zones."

The Company will make an announcement once drilling commences and will provide ongoing results as they are received.

About the Alces Lake Project

The Alces Lake project encompasses some of the highest-grade total and critical^* REE and gallium mineralization in the world, hosted within several surface and near-surface monazite occurrences that remain open at depth and along strike.

^* Critical rare earth elements/oxides (CREO) are defined here as those that are in short-supply and high-demand for use in permanent magnets that enable modern electronic applications such as electric vehicles and wind turbines. The "magnet alloy" CREO are neodymium (Nd), praseodymium (Pr), dysprosium (Dy) and terbium (Tb).

The Alces Lake project is located in northern Saskatchewan, the same provincial jurisdiction that the Saskatchewan Research Council (SRC) is developing a "first-of-its-kind" rare earth processing facility in Canada. The Alces Lake project area is ~ 38,522 hectares (~95,191acres) in size and is 100% owned by Appia.
