- The rare earth element (REE) showing is located immediately south of the southeast end of a small lake, approximately 1 mile (1.6 km) south of the middle of Alces Lake.
The showing area is underlain by a northeast-trending granite gneiss of Tazin age.
The Alces Lake REE showing is in the form of monazite, a phosphate containing Ce and La, and thorium. The monazite [Ce,La,Nb,Th)(PO4,SiO4)] occurs as red resinous crystals in a biotite band of pegmatite, 4 to 6 ft (1.2 to 1.8 m) wide, striking north and extending approximately 300 ft (91 m) along the southeast and northwest sides of a northwest-trending draw. The band was trenched at 100 ft (30.5 m) intervals and is exposed in two trenches (locations 329242.28E, 6618115.71N and 329233E, 6618140.94N). High radioactivity has been recorded near by.
Samples from the trenches have been assayed and returned values of up to 16% rare earths and 3% thorium. Normand (2014) provides a detailed description of the Alces Lake geology and mineralization. He relates the monazite-rich mineralization to bioitite segregations in metasedimentary rocks and pegmatites. 2010 rock sampling program of historical trenches and outcrops (AF MAW00115).

Appia reported on the discovery of exceptionally elevated REE assays (up to 36.1 wt% total rare earth oxides (TREO)) from outcrop grab samples at its West Limb anomaly. At the Wilson–Richard–Charles–Bell (WRCB) area, Appia also drill-expanded high-grade (Wilson zone; up to 8.98 m at 9.46 wt% TREO from hole 22-WRC-024) and low-grade (Amp zone; up to 12.13 m at 0.33 wt% TREO from hole 22-WRC-016) REE mineralization. Drilling of 34 holes at their Magnet Ridge anomaly returned up to 0.317 wt% TREO over 19.85 m in hole 22-AUG-031. A NI 43-101 technical report on Appia’s Alces Lake property was released in March 2023; the report provided a detailed account of the work done on the property up to that date.

Early in 2024, Appia reported on the results of geochemical assays obtained from its 2023 drilling program conducted on the Magnet Ridge zone of the Alces Lake project. Drilling consisted of 11 step-out holes from eight collars. The assay results returned up to 1.57 wt% total rare earth oxides (TREO) with thickness and grades increasing to the south-southeast. Mineralization intervals occur from near surface to <85 m depth. An example of one of the highest-grade intercepts was 21.91 m grading 0.366 wt% TREO, including 2.67 m grading 0.660 wt% TREO (drillhole 23-MR-001).
In addition to the Alces Lake project, Appia discovered REE mineralization while exploring for uranium on two properties located in the Wollaston Domain: the Eastside and the Loranger project areas. Rare earth elements occur with uranium in both areas. A 1 m section of a channel sample collected on the Eastside project assayed 0.14% TREO. Sporadic REE-rich results were obtained from analysis of drill core from the Loranger property and included an intersection of 0.18 m of 0.56 wt% TREO (24-LOR-003) and 0.10 m of 0.36 wt% TREO (24-LOR-003).

6/14/1988 The showing was first discovered on the CE claim no. 7, one of 21 claims staked by J. Wilson in 1954.
Wilson carried out surface work including trenching, sampling and mapping. Claims in the CE group began to lapse in 1955 and by 1958 only two remained.
All of the claims had lapsed by 1967 when the whole area was included in CBS 1182. The claim block lapsed at the end of 1967.
On 12 September 2000, M. Lederhouse staked the showing as S-106648 for Great Western Gold Corporation. Appia Energy Corp. programs in 2010 (AF MAW00115) and 2013 (MAW00432.
