Appia to Conduct a Targeted, High Resolution, Airborne Gravity Survey over the REE-Rich Alces Lake Property, Saskatchewan, Canada

Toronto, June 6, 2024 - Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") is pleased to announce the upcoming Falcon Airborne Gravity Gradiometer (AGG) and Magnetic survey over its Alces Lake property in northern Saskatchewan. This survey, conducted by Xcalibur Multiphysics, aims to provide high-resolution, low-noise subsurface imaging of the Alces Lake lithological units and structure. The data will guide Appia's future exploration efforts, targeting the dense mineralization hosts (i.e. biotite pegmatites, high-grade veins, amphibolites, Fe-Mg-rich paragneisses) of the property's rare earth element (REE) occurrences.

Stephen Burega, President, stated: "I am very excited to announce we are launching a high-resolution Falcon Airborne Gravity Gradiometer and Magnetic survey over high priority areas of our Alces Lake property. This survey will provide critical data to guide our future exploration and identify new rare earth element targets beneath the surface at depths of 200 to 1,000 meters, marking a significant step in our exploration strategy."

Starting in early June 2024, the Falcon AGG Survey will cover 1,053 line kilometers with 100-meter line spacing, focusing on the Alces Lake regional fold and the northern portion of the property's NW-SE regional shear zone (Figure 1). These areas host the property's most significant REE occurrences to date, including the high-grade WRCB zone, and high-tonnage Magnet Ridge and AMP zones. This survey will not only highlight the unique characteristics of these discovered mineralized zones, but also identify new, similar targets at unexplored depths of 200 to 1,000 meters. This advanced survey is a significant step in Appia's exploration strategy, providing crucial data to integrate and interpret with other geophysical, outcrop, and drillhole data sets for delineating future drilling targets in late 2024 and 2025.
