21,868 ha.

Otherside is located in the north-central part of the Athabasca Basin, northern Saskatchewan. The NE tip of the property is approximately 28 km S of the village of Fond-du-Lac, 80 km WSW of the village of Stony Rapids, and 98 km ESE of the village of Uranium City. Highway 905, which services Stony Rapids, is situated 73 km E of the property. A winter road is constructed annually to provide service to Uranium City from Stony Rapids.

Planned Exploration

Spring 2017: Independent review and compilation of historic geophysical works

Summer – Fall 2017: Follow-up detailed ground TAMT and/or gravity surveys

Current Exploration

March 2016: Appia stakes 6 mineral claims (21,868 ha.) for the Otherside property

Historic Exploration

Historic exploration for uranium on the Otherside property has occurred over three separate timeframes; from 1968 to 1970, 1978 to 1980, and 2005 to 2010.

Reprocessing/interpretation of 2006/07 AMT-MT surveys
  • The Otherside property is situated within the Tantato Domain.  The regional magnetic features and geology of the Tantato and Lloyd Domain (south of the property, host to Fission’s 100 M lbs. U3O8 Triple R deposits and NexGen’s 200 M lbs. U3O8 Arrow deposit.) appear to be similar enough to be considered correlative below the Athabasca Basin. 
  • Basement rock types identified in the immediate project area, in geochronological order from youngest to oldest; McKenzie diabase dykes, Hudsonian granitoids, Proterozoic metasedimentary gneisses (pelitic and psammopelitic [+/- graphite]), and mafic granulite, and Archean granitic gneiss. These basement rock types are similar to those observed at Triple R and Arrow.
  • The basement rocks of the property are unconformably overlain by approximately 800 m to 1100 m thick sedimentary sequences of the Athabasca Basin.  The stratigraphy, from the unconformity up to the surface, are summarized as;
    • Manitou Falls Formation
    • Lazenby Lake Formation
    • Wolverine Point Formation
    • Locker Lake Formation
    • Otherside Formation
  • Predominant structures in the property area are characterized by NE to ENE-trending shear zones and mylonites.  A large 40 km-long structure, with at least over 100 m vertical off-set of sandstone formations, has been interpreted on the property.
