Planned Exploration


Current Exploration

  • Summer 2018: Phase II – August to September: Diamond drilling at REE zones (Charles, Ivan and Wilson)
  • Summer 2018: Phase I – June to September: Completed over burden stripping, surface delineation and mapping, and channel sampling of seven REE zones (Bell, Charles, Dante, Dylan, Ivan, Wilson, and Wilson South-Central)
  • August to September 2017: Appia completes a regional ground prospecting program. The program successfully identified 4 new areas of surface mineralization at the Wilson, NW Wilson, Danny and Hinge zones. Geochemical assay highlights from the program include a maximum 49.64 wt% Total REO from the previously discovered Ivan zone. All samples show uniformly high concentrations of critical REEs, such as Neodymium (Nd) and Praseodymium (Pr). Assay results and maps can be accessed at the “Geochmistry Results” and “Maps” tabs above.
  • June 2017: Appia becomes 100% owner of the Alces Lake property
  • May 2016: Appia commissioned Geotech Ltd. to fly a helicopter-borne VTEMTM Plus Time-Domain EM, magnetic and radiometric survey over approximately 154.3 line-km of the property (Final Results posted in News Release for July 19, 2016, or see Maps section of Alces Lake).
  • May 2015: Appia stakes 8 additional mineral claims (4,232 ha.) adjacent to the north and south of mineral claim S-112033
  • September to October 2013: Joint Venture conducts small ground VLF-EM and magnetic surveys over Alces Lake occurrence, additional prospecting and sampling, discovery of Ivan zone REE-U zone, assayed results return over 34 wt% TREE and 0.05 wt% U3O8
  • January 2013 to February 2014: Scott Bell transfers 40% ownership to Appia in 3 separate stages
  • October 2011: the Joint Venture conducts radiometric prospecting and rock sampling program, samples return over 5% TREE and 800 ppm U
  • December 2010: Scott Bell stakes mineral claim S-112033 (1,518 ha.), transfers 50% ownership to Appia

Historic Exploration

  • Three zones of surface mineralization on the Alces Lake property were first discovered by radiometric prospecting in the 1950’s; i) Alces Lake rare earth, ii) HALL-GRIF uranium, and iii) Scrub uranium.  A new high-grade rare earth surface discovery, the Ivan zone, was discovered 90 m NE of the Alces Lake zone in 2013.  It should be noted that the HALL-GRIF and Scrub showings have not been re-visited since the 1950’s.  
  • Alces Lake is located within the Beaverlodge Domain.  The Beaverlodge Domain was host to over 17 individual uranium mines, having produced a total of 70 M lbs. U3O8 at an average grade over 0.20 wt% U3O8
  • Rock types identified on the property include, in geochronological order from youngest to oldest; Proterozoic metasedimentary gneisses (pelitic and psammopelitic [+/- graphite], quartzite, amphibolite, pyroxenite, diatexite), and feldspathic gneisses, and Archean granitic gneiss. The basement rock sequence of the metasedimentary gneisses is similar to those of the Beaverlodge deposits.
  • The property boundary is approximately 28 km N of the current day Athabasca Basin margin.
  • The St. Louis Fault, a regional scale fault, runs ENE-WSW in the northern portion of the property under the Alces Lake waterbody.  The St. Louis Fault is a major tectonic boundary between the Beaverlodge and Train Domains, and also hosts at least 3 uranium deposits which produced over 45 M lbs U3O8


  • The Alces Lake REO geochemical assay results rank as the highest-grade REE known occurrence in the province of Saskatchewan.  The results showcase world-class REO grades that are comparable to those encountered in the world-class Steenkampskraal deposit, South Africa
  • Radioactivity measurements at the Alces Lake occurrences have consistently exceeded 56,000 total counts per second (off-scale radioactivity) as measured with a RS-230 BGO Super-Spec hand-held spectrometer.  The radioactivity is mainly due to the presence of Th.
  • The Wilson zone REE mineralization is described as 1 to 3 cm thin lenses of mm-sized grains of monazite within 1.2 to 1.8 m thick biotite-rich segregation bands hosted by K-rich granitic pegmatite.  Monazite accounts for approximately 15% to 20% of the lenses.  The Wilson zone mineralization is hosted within pegmatite at the metamorphosed paleoProterozoic unconformity between metasedimentary gneiss and orthogneiss.
    • Channel samples from the Wilson zone in 2017 have returned values of up to 18.53 wt% Total REO over 2.7 m
  • The Ivan zone REE mineralization is described as massive mm-sized monazite grains.  The REE mineralization is in sharp contact with surrounding host-rock, suggesting possible structural controls
    • Channel samples from the Ivan zone in 2017 have returned values of up to 45.92 wt% Total REO over 1.85 m
  • The Danny zone REE mineralization is described as cm-scale clusters of mm-sized monazite grains within leucocratic (feldspar and quartz) parts of granitic pegmatites.  The Danny zone mineralization is hosted within granitic orthogneiss.
    • Grab samples from the Danny zone in 2017 have returned values of up to 13.63 wt% Total REO
  • The Charles zone REE mineralization is described as locally massive to disseminated cm- to m-scale clusters of mm-sized monazite grains within leucocratic (feldspar and quartz) parts of pegmatites, and along biotite-rich schists along the margins of the pegmatites.  The Charles zone mineralization is hosted within semipelitic gneiss.
    • Channel samples from the Charles zone in 2018 have returned values of up to 14.90 wt% Total REO over 5.1 m
