APPIA PLANS A 3,300 METRE SUMMER DRILL PROGRAM AT THE ALCES LAKE RARE EARTH ELEMENTS PROPERTY

Appia Rare Earths & Uranium Corp. has provided an update on its Alces Lake rare earth element property in Northern Saskatchewan, where the company has finalized its exploration plans, logistics and contractor arrangements for an approximately 3,300-metre, nine-hole diamond drill program, with mobilization scheduled to begin on or about May 29, 2026.

The coming 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 of the regional northwest-southeast structural corridor, the same corridor that hosts the property's prolific WRCB and Magnet Ridge zones.

Tom Drivas, chief executive officer 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 continuing 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 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, praseodymium, dysprosium and terbium.

The Alces Lake project is located in Northern Saskatchewan, the same provincial jurisdiction where the Saskatchewan Research Council is developing a first-of-its-kind rare earth processing facility in Canada. The Alces Lake project area is approximately 38,522 hectares (approximately 95,191 acres) in size and is 100 per cent owned by Appia.

About Appia Rare Earths & Uranium Corp.

Appia is a publicly traded Canadian company in the rare earth element and uranium sectors. The company holds a 25-per-cent interest in the Ultra hardrock and Ultra IAC projects, which total 42,932.24 hectares in size and are located within the state of Goias in Brazil. Ultra is obligated to acquire Appia's 25-per-cent interest in the Ultra hardrock and Ultra IAC projects in exchange for a 25-per-cent equity interest in Ultra once a prefeasibility study has been prepared in respect of the Ultra IAC project and a mineral resource estimate has been prepared in respect of the Ultra hardrock project (see Nov. 4, 2025, press release).

The company is also focusing on delineating high-grade critical rare earth elements and gallium on the Alces Lake property and exploring for high-grade uranium in the prolific Athabasca basin on its Otherside, Loranger, North Wollaston and Eastside properties. The company holds the surface rights to exploration for 94,982.39 hectares (234,706.59 acres) in Saskatchewan. The company also has a 100-per-cent interest in 13,008 hectares (32,143 acres), with rare earth element 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.
