North Wollaston Region Overview

The North Wollaston property is situated in northeastern Saskatchewan and is 35 km northeast of Cameco’s Rabbit Lake uranium mill and Eagle Point mine operations.  North Wollaston is located 42 km north of the Company’s Loranger property and Wollaston village.  The property is close to infrastructure, such as all-season highway, powerline, and air strips.

Planned Exploration

Spring – Summer 2018: Airborne EM, magnetic and radiometric survey

Summer – Fall 2018: Ground prospecting

Current Exploration

  • November/December 2017: Appia stakes 14 mineral claims (11,306 ha.) for the North Wollaston property

Historic Exploration

Historic exploration for uranium over the North Wollaston property has occurred over 2 separate timeframes; from 1968 to 1971 and 1978 to 1984.

Petrographic studies
  • 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 geochronogical order from youngest to oldest; Hudsonian pegmatite, Proterozoic metasedimentary gneisses (arkosic to quartzitic to cordierite-garnet-[+/- graphite] pelitic to calc-silicate), and Archean granitic gneiss.  The calc-silicate rocks are believed to be part of the Hidden Bay assemblage, the rock unit that hosts the Rabbit Lake-Collins Bay-Eagle Point and Raven-Horseshoe uranium deposits.  The occurrence of quartzitic gneiss adjacent to cordierite-garnet-graphitic gneiss is similar to rock types hosting both McArthur River and the Phoenix deposits; two of the highest-grade uranium deposits in the world.
  • The property boundary is approximately 30 km northeast of the current day Athabasca Basin margin.  Evidence suggests the property was covered by Athabasca sandstones during time of uranium deposit formation.
  • Prospecting programs have identified 3 main fault trends; NE-trending graphitic fault zones, ENE-trending [+/- graphite] fault zones cross-cutting the NE-trending faults, and N-S trending faults part of the Tabbernor fault system.

Mineralization

North Wollaston Property Overview
  • A Total of 4 major and 2 minor uranium showing areas have been observed at surface on the property; major showings are Dan’s, Wheeler #1, Wheeler #2 and Wheeler #3, and minor showings are Wetego Bay and Rusty Hill
  • Dan’s uranium showing is hosted within sheared pegmatite segregations of the Wollaston metasediments.  The showing is comprised of a 100 m long down-ice boulder field with uranium values from boulders ranging from 100 ppm to 1,700 ppm U3O8 (average 500 ppm U3O8).  The source of the boulder train was traced to an outcrop that has identical geology.  Uranium values from the outcrop returned a range of 100 ppm to 0.495 wt% U3O8.  An up-ice boulder field from the outcrop hosts boulders which average 1,300 ppm U3O8, and the boulder source has yet to be discovered.  Silicification, chloritization and clay alteration types have all been observed with varying degrees of intensity, and hematite/limonite and secondary uranium minerals frequently coat fracture linings.  The structures and alteration observed at Dan’s uranium showing are similar to other high-grade uranium deposits, and suggest that this showing area could be part of a larger mineralized system. 
  • Wheeler #1 uranium showing consists of numerous pegmatoids exhibiting elevated uranium values within metasedimentary gneiss.  The highest assay from outcrop returned 0.40 wt% U3O8.     
  • Wheeler #2 uranium showing is similar to Wheeler #1, with the exception of pegmatoids being associated with calc-silicate gneisses.  Due to the nature of the exposure of the radioactive areas, samples could not obtained.
  • Wheeler #3 uranium showing is an up-ice boulder field from Wheeler #2, the source has yet to be identified.  Yellow secondary uranium minerals have been observed coating fracture linings.  A maximum value of 0.13 wt% U3O8 has been reported from the boulder field. 
  • Two other minor radioactive outcrops were observed close to Wheeler #2 and Wheeler #3; Wetego Bay and Rusty Hill. 
    • Wetego Bay is hosted by pegmatites within calc-silicate gneiss and believed to be contiguous with Wheeler #2. 
    • Rusty Hill is an iron-rich weathered outcrop, radioactivity was observed in pegmatite, metasediment gneiss, and weakly altered, fractured quartz-flooded unit.
