Appia has NI 43-101 compliant resources of 8.0 M lbs U3O8 and 47.7 M lbs TREE Indicated, and 47.7 M lbs U3O8 and 133.2 M lbs TREE Inferred in the Elliot Lake, ON, historic mining camp. The resources are largely unconstrained along strike and down dip.
- Historic Mining
- The town of Elliot Lake is located in northern Ontario. By road, the town is i) 30 km N of the Trans-Canada Highway (Highway 17); ii) 168 km W of the nickel-mining district of Sudbury, ON; iii) 201 km E of Sault Ste. Marie, ON, the gateway to Michigan, USA, and iv) 58 km NE of Blind River, ON, where Cameco operates the world’s largest commercial uranium refinery.
- The Elliot Lake uranium-REE property comprises a group of 101 staked mineral claims, approximately 3km north of the town of Elliot Lake.
- During the period 1955 through 1996, a total of 362 million pounds of U3O8 (313.5 million pounds of uranium metal) was produced from approximately 177 million tons of ore having an average grade of 0.106 wt% U3O8 (898 ppm U or 2.12 lbs U3O8 per short ton) from 13 underground mines in the Elliot Lake mining camp.
- Uranium mineralization of the Elliot Lake area is readily leachable, which facilitated high recoveries, typically 95%, in the operating mines
- Between 1949 and 1996, more than 100 drill holes have been drilled on what is now Appia’s Elliot Lake property
- June 2014: Appia staked one additional mineral claim for the Elliot Lake property
- July 2013: A second NI 43-101 compliant resource estimate is completed to update the Teasdale Lake zone
- June to September 2012: A total of 16 drill holes are completed from surface in the Teasdale Lake zone for a total of 8,130.2 m
- July 2011: An initial NI 43-101 compliant resource estimate is produced for the Teasdale Lake and Banana Lake zones
- October to December 2008: two drill holes are completed from the surface on the Banana Lake zone for a total of 3,109.0 m
- November 2007 to March 2008: Appia completed 10 diamond drill holes for a total of 3,885.2 m in the Teasdale Lake and Banana Lake zones
- Teasdale Lake: 6 drill holes for a total of 2,644.0 m
- Banana Lake: 4 wedged drill holes from two historic drill holes for a total of 1,241.2 m
- 2006: Geophysical surveying included airborne MEGATEM EM and magnetic survey by Fugro Airborne Surveys, and 3 line ground dipole-dipole IP test survey by Gradient Geophysics Inc.
- May 2004 to December 2009: 100 mineral claims are staked in the Elliot Lake area by Appia Energy Corp., Canada Enerco Corporation (“CEC”) and Dan Patrie Exploration Ltd. (“DPEL”). All claims staked by CEC and DPEL are subsequently vended to Appia, forming the Elliot Lake property

- Uranium and REE metals are hosted within quartz-pebble conglomerate beds that are found in the Matinenda Formation, which is the basal unit of the Elliot Lake Group. The uranium and REE-bearing horizon is a clean, well-sorted, coarse-pebble conglomerate
- Uranium mineralization is stratabound, showing good consistency in grade and thickness over wide areas, both along strike and down dip.
- The uranium mineralization is predominantly brannerite and uraninite, both of which are readily leachable.
