Athabasca Basin Properties

The Eastside property is situated in northeastern Saskatchewan and is 7.0 km west of the Manitoba border. Eastside is located 50 km east of the Company’s Loranger property and 85 km east of Cameco’s Rabbit Lake uranium mill and Eagle Point mine.

Planned Exploration

Summer 2020: Field reconnaissance and prospecting

Current Exploration

November 2017: Appia covers 1,178 line kilometers of Eastside property with an airborne High Resolution Aeromagnetic Gradiometer, Radiometric and Digital Matrix VLF-EM survey.  The survey confirmed the presence of a historic radiometric anomaly that led to the discovery of uranium-rich boulders and outcrops, but also identified more radiometric anomalies that have never been explored.  The magnetic results of the survey showed known mineralization occurs along a regional “bend”, as well as correlating with magnetic gradients.  Numerous magnetic features are offset and are interpreted as fault zones (see News Release for November 13, 2017).

June 2017: Appia stakes 10 mineral claims (4,933 ha.)

Historic Exploration

Historic exploration for uranium in the Eastside property area has occurred over two separate timeframes; from 1969 to 1970 and 1975 to 1980.

Exploration History from 1969 to 1970

Exploration History from 1975 to 1980

• The property is located within the Archean-aged Peter Lake Domain.  The Peter Lake Domain is a fertile source for platinum group elements (PGE), gold and copper mineralization, however many surface uranium occurrences have also been identified within the Domain.   
• Rock types identified on the property include, in geochronological order from youngest to oldest; granitic rocks of Paleoproterozoic intrusive Wathaman Batholith, neoArchean gabbroic to dioritic to ultramafic rocks (hornblende-rich varieties very common), and Archean granodioritic to tonalitic migmatitic gneiss interbedded with a variety of other granitoid rocks and gneisses.  Pegmatite partial melts are common in all rock types.
• The presence of very mafic-rich to gabbroic rock units is a common feature in some Athabasca high-grade uranium deposits, including Fission’s Triple R deposits and NexGen’s Arrow deposits.  Kivalliq’s Lac 50 uranium deposit in Nunavut is entirely hosted within metamorphosed basalts (i.e. mafic-rich rock types).
• The property boundary is approximately 85 km E of the current day Athabasca Basin margin.  The uranium deposit model for the Eastside property is near-surface,  pegmatite-hosted high-grade uranium (+/- structural controls).  Athabasca Basin cover is not necessary for this uranium deposit model.

Airborne radiometric surveys led to the discovery of radioactive boulders, till and outcrop in the property area.  Ground prospecting and sampling of boulders and outcrops returned a range of 2 to 7,575 ppm uranium, producing an average grade of 360 ppm uranium.  Twelve samples contained greater than 1,000 ppm uranium.  

Three outcrop samples along a 1.7 km geological strike returned 2,538 ppm, 6,650 ppm and 7,575 ppm uranium.  Five boulders of similar lithological provenance to the outcrops, and located down-ice from the outcrops, returned greater than 1,000 ppm uranium.

The boulders with highest uranium occurrences are derived from hornblende-bearing pegmatites within hornblende-rich felsic gneisses.
