Toronto, Ontario--(Newsfile Corp. - October 23, 2024) - Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") is excited to announce the commencement of its diamond drilling program in the southwest corner of Target IV. The goal of this program is to identify and delineate a possible Rare Earth Elements (REE) highgrade area at depth, identified by previous Reverse Circulation (RC) drilling (See January 16th 2024 Press Release), associated with a carbonatitic breccia intrusion or dike.

Stephen Burega, President, stated, "We have been eager to get a drill back to the highgrade mineralized area found in the Southwest of Target IV since the discovery was first made at the beginning of 2024. This extraodianary mineralization included 92,758 ppm or 9.28% TREO across 2 metres. At the time, we were limited to testing the extent of the zone due to high ground water levels. Moving forward with a diamond drill rig, this program allows us to test the extent of the clay materials and explore the hardrock potential at depth."

The program will include up to 450 meters of drilling in three 150 metres drillholes and is expected to be completed within a +/-25-day timeline (See Map 1).
