APPIA BEGINS DIAMOND DRILLING TO DELINEATE POTENTIAL HIGHGRADE MINERALIZATION AT PCH TARGET IV IN GOIAS, BRAZIL

Appia Rare Earths & Uranium Corp. has begun its diamond drilling program in the southwestern corner of target 4. The goal of this program is to identify and delineate a possible rare earth element (REE) high-grade area at depth, identified by previous reverse circulation (RC) drilling (see Jan. 16, 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 high-grade mineralized area found in the southwest of target 4 since the discovery was first made at the beginning of 2024. This extraordinary mineralization included 92,758 parts per million, or 9.28 per cent, TREO [total rare earth oxides] across two metres. At the time, we were limited to testing the extent of the zone due to high groundwater 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 metres of drilling in three 150 m drill holes and is expected to be completed within a plus/minus 25-day timeline.

On March 1, 2024, the company released its maiden mineral resource estimate (MRE) on target 4 and the Buriti zone, and the companion National Instrument 43-101 technical report on the PCH project was filed on April 16, 2024.

The technical information in this news release, including the information related to geology, drilling and mineralization, has been reviewed and approved by Andre L. L. Costa, Appia's vice-president of exploration for Brazil, with more than 29 years of relevant experience. Mr. Costa is an APEGS (Association of Professional Engineers and Geoscientists of Saskatchewan) professional geoscientist (PGeo), a fellow of the Australian Institute of Geoscientists (FAIG), and a qualified person as defined by NI 43-101.
