Appia has NI 43-101 Mineral Resources of 14,435,000 tons grading 0.554 lbs. U3O8/ton and 3.30 lbs. TREE/ton for a total of 8.0 M lbs U3O8 and 47.7 M lbs TREE Indicated and 42,447,000 tons grading 0.474 lbs. U3O8/ton and 3.14 lbs. TREE/ton for a total of 20.1 M lbs. U3O8 and 133.2 M lbs. TREE Inferred in the Teasdale Zone plus 30,315,000 tons grading 0.912 lbs. U3O8/ton for a total of 27.6 M lbs U3O8 Inferred in the Banana Lake Zone in the Elliot Lake, ON, historic mining camp. The resources are largely unconstrained along strike and down dip. *Refer to the Teasdale Lake zone and Banana Lake zone pages for qualifying notes regarding the Mineral Resource estimates, and individual element grades supporting the reported TREE results.
- 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 Rare Earths & Uranium 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.
