June 04, 2026 (Source) — Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQB: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the “Company” or “Appia“) is pleased to announce that mobilization has commenced for its approximately 3,300-metre, 9-hole diamond drill program at the Company’s 100%-owned Alces Lake Rare Earth Elements (“REE”) Property in northern Saskatchewan.
Initial mobilization began on May 29, 2026, with camp personnel arriving on site to prepare the Alces Lake exploration camp for the upcoming summer program. Geologists, drilling crews and support personnel are expected to mobilize following completion of camp setup and site preparations, which are anticipated to be finalized within approximately one week.
The 2026 summer drill program is designed to evaluate several high-priority REE targets (Figure 1) identified through Appia’s 2025 ground gravity survey, which refined and enhanced target areas initially outlined by the Company’s 2024 airborne gravity gradiometer survey. Targets 1, 5, 6 and 7 (Figures 2 to 5) have been prioritized based on their strong geophysical similarities to the high-grade WRCB mineralized zone and the large near-surface Magnet Ridge discovery.
The planned program will consist of approximately 3,300 metres of drilling across nine diamond drill holes targeting depths ranging from 300 to 500 metres. The objective is to test the potential continuation of REE-mineralized lithological packages at depth and along strike within the regional northwest-southeast structural corridor that hosts several of the property’s key mineralized zones, including WRCB and Magnet Ridge.
“We are excited to begin our 2026 summer exploration program at Alces Lake,” said Tom Drivas, Chief Executive Officer and Director of Appia. “This drill program is designed to test high-priority REE targets at depth that exhibit strong geophysical similarities to the known WRCB and Magnet Ridge mineralized zones. With camp mobilization now underway, we look forward to advancing the project and commencing drilling on these compelling targets.”
The Alces Lake Property hosts some of the highest-grade rare earth element mineralization identified in Saskatchewan. The property covers approximately 38,522 hectares in northern Saskatchewan and is enriched in critical rare earth elements including neodymium, praseodymium, dysprosium and terbium, which are essential components in permanent magnets used in electric vehicles, wind turbines and advanced electronic technologies.
The Company will make an announcement once drilling commences and will provide ongoing results as they are received.

About the Alces Lake Project
The Alces Lake project encompasses some of the highest-grade total and critical* REE 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/oxides (CREO) are defined here as those that are in short-supply and high-demand for use in permanent magnets that enable modern electronic applications such as electric vehicles and wind turbines. The “magnet alloy” CREO are neodymium (Nd), praseodymium (Pr), dysprosium (Dy) and terbium (Tb).
The Alces Lake project is located in northern Saskatchewan, the same provincial jurisdiction that the Saskatchewan Research Council (SRC) is developing a “first-of-its-kind” rare earth processing facility in Canada. The Alces Lake project area is ~ 38,522 hectares (~95,191acres) in size and is 100% owned by Appia.
