APPIA ANNOUNCES 2021 ASSAY RESULTS AND DISCOVERY OF A SIGNIFICANT NEW MINERALIZED ZONE AT ALCES LAKE RARE EARTH PROPERTY, NORTHERN SASKATCHEWAN

Appia Rare Earths & Uranium Corp. has released complete WRCB assay results from its 2021 drilling program; it says it has discovered a massive new rare earth element (REE) bearing zone in the WRCB area of the 100-per-cent-owned Alces Lake high-grade rare earth elements and gallium property, Athabasca basin area, Northern Saskatchewan. Further assay results from 2021 drilling in the Western Anomaly area of the Alces Lake claims block will be released in the near future.

Highlights:

• Wilson 21-WRC-014 intersected 15.81 weight per cent total rare earth oxide (TREO) over a drilled width of 3.67 metres within a broader interval of 6.99 m at 11.70 weight per cent TREO (see "Summary of 2021 high-grade assay results at WRCB" table);
• Wilson 21-WRC-016 intersected 24.30 weight per cent TREO over a drilled width of 1.93 m within a broader interval of 3.19 m at 15.38 weight per cent TREO and 17.85 weight per cent TREO over a drilled width of 2.69 m within a broader interval of 11.6 m at 5.71 weight per cent TREO (see "Summary of 2021 high-grade assay results at WRCB" table);
• Richard 21-WRC-053 intersected 17.12 weight per cent TREO over a drilled width of 1.08 metres within a broader interval of 4.29 m at 5.19 weight per cent TREO (see "Summary of 2021 high-grade assay results at WRCB" table);
• High-grade at-or-near-surface mineralization at WRCB now correlated along strike length for 100 metres;
• New discovery of the AMP zone, which is continuous from surface to a down-plunge extent of 300 metres and remains open. The true width of the mineralized zone is known to exceed 10 metres.

Frederick Kozak, president of Appia, said: "The wait for the assay results was worth it. Appia has identified the continuity of the WRCB shallow high-grade mineralization with a strike length of approximately 100 metres and consistently strong assay values. However, the new discovery of the massive AMP zone from surface to depth has revealed it is large and continuous across all of the WRCB area and open along strike within the NNW [north-northwest] trending kilometre-scale structural corridor. This could be a blockbuster for future rare earths production, as Appia continues to move the Alces Lake rare earths discovery towards potential development."

The shallow zones at WRCB show the high-grade mineralization and its continuity over approximately 100 metres of strike length -- drilling in 2021 has essentially confirmed the separately named segments of WRCB as one continuous accumulation of high-grade mineralization. Approximately 54 holes were drilled at WRCB in 2021, for a total of 5,297 metres. To the end of 2021, 119 holes have been drilled into WRCB for a total of 8,590 metres.

Hosted within a planar geological structure, the AMP zone is defined by a plunging chute of mineral enrichment and interpreted tectonic thickening. This is a newly discovered style of mineralization at Alces Lake, identified and delineated for the first time in 2021. Outcropping in the WRCB area, the zone has uninterrupted continuity from surface to a down-plunge extent of 300 metres and remains open down-plunge.

The following tables summarize the assay results from previously released assays and additional assay results from representative holes in WRCB. The 2021 drilling program confirms the continuity and consistency of the shallow high-grade mineralization in WRCB. The "Summary of 2021 AMP zone assay results at WRCB" table summarizes the assay results from the deeper AMP discovery.

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.

Appia recommenced drilling at Alces Lake in mid-March, 2022, and plans to drill significantly deeper holes compared with the 100 holes (approximately 8,076 metres) drilled in 2021. This is designed to allow Appia to determine continuity at depth and along the identified REE mineralization trends as the company works toward a maiden resource estimate in accordance with National Instrument (NI) 43-101 for the area. With high-grade REE mineralization now identified in many locations within an area covering approximately 27 square kilometres of the Alces Lake block, the company believes the project has the potential to be a world-class source of high-grade critical rare earth bearing monazite.

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 operational in early 2023). The Alces Lake project area is 35,682 hectares (88,173 acres) in size and is 100-per-cent-owned by Appia.

To ensure safe work conditions are met for the work force, the company has developed exploration guidelines that comply with the Saskatchewan Public Health Orders and the Public Health Order respecting the Northern Saskatchewan administration district in order to maintain social distancing and help prevent the transmission of COVID-19.
