APPIA CORRECTS DRILL HOLE DEPTHS REPORTED IN AUGUST 6, 2026 ALCES LAKE NEWS RELEASE

Appia Rare Earths & Uranium Corp. has corrected the company's Aug. 6, 2026, news release entitled "Appia Intersects REE-Bearing Monazite in Three of Six Drill Holes and Completes 2026 Alces Lake Summer Drill Program."

The table of the Aug. 6 release contained incorrect final drill hole depths, and the corrected final drill hole depths are provided in the table below. Based on these corrected depths, the six-hole program total is 1,471.32 metres, replacing the previously reported total of 1,440.87 metres.

The monazite-bearing interval depths reported in the Aug. 6, 2026, release were correct and are not affected by this correction.

Interpreted monazite-bearing intervals and apparent widths include the following:

• Drill hole 26-ALF-001 intersected monazite from approximately 216 to 220 metres.
• Drill hole 26-RSC-002 intersected two monazite-bearing intervals from approximately 71 to 78 metres to 84 to 90 metres.
• Drill hole 26-RSC-004 intersected monazite from approximately 202 to 214 metres.

About the Alces Lake project

The Alces Lake project encompasses some of the highest-grade total and critical* rare earth element 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, where the Saskatchewan Research Council is commissioning its rare earth processing facility. SRC schedules completion of commissioning by December, 2026, with operations following ramp-up in 2027. The Alces Lake project area is approximately 38,522 hectares (approximately 95,191 acres) in size, and is 100 per cent owned by Appia.

The technical content in this news release was reviewed and approved by Dr. Irvine R. Annesley, PGeo, senior exploration adviser of Appia, a qualified person as defined by National Instrument 43-101.
