Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (Germany: “A0I.F”, “A0I.MU”, “A0I.BE”) is excited to announce the release of assay results from 2022 diamond drilling of various regional exploration targets at its 100%-owned Alces Lake Rare Earth Elements (REES) Property, Northern Saskatchewan.

Final assays for Appia’s 2022 Alces Lake diamond drilling program have been received, compiled, and interpreted zone-by-zone, the third (and final) set of results is reported here. In 2022, The Company completed an extensive diamond drilling campaign of regional exploration targets. Targets were identified primarily through the interpretation of the company’s 2021 Airborne Radiometric (U, Th, K) survey in conjunction with its 2021 and 2022 prospecting results. Table 1 below highlights the most significant geochemical assay results from the regional drilling program. Table 2 provides the collar information for all of the drill holes from the 2022 regional diamond drilling program. The complete assays results are available in Table 3 by clicking on this link.

The Magnet Ridge West Target (Figures 1 and 2), first identified and drilled in 2022, returned multiple intervals of a REE (monazite-bearing) mineralization over significant drill widths, including:

• 15.78m @ 0.201 wt.% TREO from hole 22-MRW-005
• 6.29m @ 0.253 wt.% TREO from hole 22-MRW-006
• 10.12m @ 0.145 wt.% TREO from hole 22-MRW-009
• Follow-up drilling is warranted

The West Limb area (Figures 1 and 3), where Appia recently reported a discovery of massive monazite at surface, returned 2.07m @ 0.447 wt.% TREO from hole 22-WEL-004. And from the large Western Anomaly area (Figures 1 and 4), DDH 22-WES-003 returned 8.31m @ 0.123 wt.% TREO.

“Combined with the recently released results from the WRCB’s high-grade Wilson Zone (See March 2nd, 2023 News Release) and the extension of the Magnet Ridge Zone’s thick sequences of REES near surface over significant strike length and drilled widths exceeding 28 metres (See March 20th, 2023 News Release), Appia’s 2022 work season produced excellent results and further established Alces Lake as the Company’s priority project,” stated Stephen Burega, President.”

He continued, “Follow-up geophysical and geochemical surveys are planned along and across the highest-priority areas of Alces Lake’s major structural corridor that extends south-southeast from the main mineralized zones at WRCB to Magnet Ridge and continues for another 20 to 25 km. A highly focussed drilling campaign will test numerous targets to further delineating the continuity of mineralization controlled by this important structural corridor.”

Vice President, Exploration Irvine Annesley says, “The scale and extent of regional REE anomalies on the Alces Lake project provides us with numerous targets to test (drill) outside of the WRCB and Magnet Ridge areas. This clearly shows us that the Alces Lake area has a lot more mineralization to discover/uncover from surface to depth. Volume and tonnage is the intended result”.

About the Alces Lake Project

The Alces Lake project encompasses some of the highest-grade total and critical* REEs 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 are defined here as those that are in short-supply and high-demand for use in permanent magnets and modern electronic applications such as electric vehicles and wind turbines (i.e: neodymium (Nd), praseodymium (Pr), dysprosium (Dy) and terbium (Tb)).

The Alces Lake project is located in northern Saskatchewan, the same provincial jurisdiction that is developing a “first-of-its-kind” rare earth processing facility in Canada (currently under construction by the Saskatchewan Research Council and scheduled to become fully operational in early 2024). The Alces Lake project area is 38,522.43 contiguous hectares (95,191.00 acres) in size and is 100% owned by Appia.

All lithogeochemical assay results of core samples were provided by Saskatchewan Research Council’s Geoanalytical Laboratory, an ISO/IEC 17025:2005 (CAN-P-4E) certified laboratory in Saskatoon, SK. All analytical results reported herein have passed internal QA/QC review and compilation.

The technical content in this news release was reviewed and approved by Dr. Irvine R. Annesley, P.Geo, Vice President, Exploration, and a Qualified Person as defined by National Instrument 43-101.
