Appia Rare Earths & Uranium Corp. announced complete WRCB assays results from its 2021 drilling program and the discovery of a massive new rare earth element ("REE") -bearing zone in the WRCB area of the 100%-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 wt% TREO over a drilled width of 3.67m within a broader interval of 6.99m at 11.70wt% TREO; Wilson 21-WRC-016 intersected 24.30 wt% TREO over a drilled width of 1.93m within a broader interval of 3.19m at 15.38wt% TREO AND 17.85 wt% TREO over a drilled width of 2.69m within a broader interval of 11.6m at 5.71wt% TREO; Richard 21-WRC-053 intersected 17.12 wt% TREO over a drilled width of 1.08 metres within a broader interval of 4.29m at 5.19 wt% TREO; 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. 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. 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 to 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 towards a maiden resource estimate in accordance with NI 43-101 for the area. With high-grade REE mineralization now identified in many locations within an area covering approximately 27 km2 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% owned by Appia. To ensure safe work conditions are met for the workforce, 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.
