Loranger is located on the southeastern shores of Wollaston Lake, northern Saskatchewan. Cameco’s Rabbit Lake uranium mill and Eagle Point mine operations are approximately 28 km to the northwest. The southwestern extension of the Loranger property is situated 10 km from all-season Provincial highway 905.

Planned Exploration

July – October 2017: Diamond drill hole exploration program

Current Exploration

  • February – April 2017: Appia completed the first seven drill holes on the Property for a total of 1,461 m. Drill holes LOR-17-001 to LOR-17-003 targeted a gravity low. The gravity low area is interpreted to result from intense brittle faulting and alteration. No anomalous radioactivity was intersected in this area. Drill holes LOR-17-004 to LOR-17-007 confirmed the presence of multiple lenses of anomalous radioactive pegmatites from near surface (19 m) down to 260 m vertical depth, and extended the limit of known anomalous radioactivity 750 m southwest along strike of historic diamond drilling on Royal Canadian Ventures Grid No 2 area ("RCV area"). (see News Release for April 12, 2017).
  • January – February 2017: Appia commissioned MWH Geo-Surveys Ltd. to conduct ground gravity surveying over approximately 45.2 km of the 94.0 km of primary structural corridors identified from the VTEMTM Max Time-Domain EM and magnetic survey. The results have identified numerous gravity lows coincident with i) breaks and/or jogs in previously defined conductive structural corridors and ii) cross-cutting structures. In particular, a number of prospective gravity lows have similar size, shape and amplitude as gravity lows associated with high-grade uranium deposits in the Athabasca Basin region, such as NexGen's Arrow deposit, Rio Tinto's Roughrider deposit, Cameco's Eagle Point deposit and UEX's Raven-Horseshoe deposits. (see News Release for February 23, 2017).
  • October 2016: Appia commissioned Geotech Ltd. to fly a helicopter-borne VTEMTM Max Time-Domain EM and magnetic survey over approximately 715 line-km of the property.  The survey identified 94 km of primary structural corridors that share similar geophysical characteristics with a number of Athabasca Basin high-grade uranium deposits.  Final results are posted here (see News Release for December 13, 2016.
  • August 2016: Appia stakes an additional 3 mineral claims (5,970 ha.) contiguous to the SW of Loranger
  • March 2016: Appia stakes 6 mineral claims (24,755 ha.) for the Loranger property

Historic Exploration

Loranger RCV Area

Historic exploration for uranium over the Loranger property has occurred over three separate timeframes; from 1968 to 1969, 1978 to 1979 and 2007.

Loranger RCV Area
  • The property is located within the eastern Wollaston Domain.  The Wollaston Domain is host to over 1 B lbs. of high-grade U3O8
  • Rock types identified on the property include, in geochronological order from youngest to oldest; Hudsonian pegmatite, Proterozoic metasedimentary gneisses (arkosic to psammopelitic to pelitic [+/- graphite] and quartzite), and Archean granitic gneiss.  This basement rock sequence is identical to that of other known high-grade uranium deposits in the Wollaston Domain.
  • The property boundary is approximately 21 km E of the current day Athabasca Basin margin.  Athabasca sandstone cover was important for the formation of economic uranium deposits.  Evidence suggests the property was covered by Athabasca sandstones during time of uranium deposit formation.
  • NE-trending graphitic fault zones and N-S-trending Tabbernor faults are the two primary fault systems on the property.  Many Athabasca high-grade uranium deposits are associated with these structural systems. 

Mineralization

  • Radioactivity and uranium mineralization were identified at surface as discontinuous pegmatites in the RCV Grid No. 2 area. 
  • Sub-surface uranium mineralization and anomalous radioactivity was intersected in 10 out of 13 DDH at RCV Grid No. 2.  See “Historic Exploration” for noteworthy DDH intersections.  The uranium mineralization is hosted in pegmatites and graphitic structures
