Elliot Lake

Ontario, Canada

Current Reports

Previous drill programs conducted in 2007-08 and 2012 aimed to confirm mineralization identified in historical resource estimates for Teasdale Lake and Banana Lake zones, 2 of 5 zones, 100% interest. Subsequent to these efforts, Appia enlisted the expertise of consulting firm Watts, Griffis and McOuat Limited (WGM) to produce an updated NI 43-101 Resource Estimate, resulting in the “2013 Updated Resource Estimate Report” filed on SEDAR.

Current Work

Appia is embarking on a reevaluation of its substantial uranium-rare earths deposits in Elliot Lake, Ontario, spurred by the surge in uranium prices and the confirmation of noteworthy rare earth element (“REE”) mineralization. The focus is on assessing the economic viability of bulk mining at the Teasdale Lake and Banana Lake Zones with an eye on potential cost savings.

Drilling Programs Confirm REE and Outlines Larger Resource in Teasdale Lake Deposit

The  2007-08 and 2012 drill programs were also carried out to determine the REE content in the various mineralized beds that comprised the Teasdale Lake deposit. Based on historical yttrium production and the presence of monazite, which is commonly enriched with REE, it was recognized by Appia that the Elliot Lake uranium deposits could contain significant REE mineralization.

The drilling programs totalled 10,780 metres and indicated that additional drilling would continue to enlarge the zones.
The drilling confirmed the presence of three mineralized units, namely the Upper Reef, Intermediate Quartzite, and the Lower Reef:
  • The 3.2 metre-thick Lower Reef horizon, which was mined extensively when the Elliot Lake camp was in production, contained significant REE mineralization and the highest uranium values.
  • The Intermediate Quartzite averaged 2.65m in thickness and was weakly mineralized with lower uranium and REE mineralization.
  • The Upper Reef, measuring 3.95m in thickness, contained the highest concentration of REE mineralization but lower uranium values compared to the Lower Reef.
  The 2013, “Updated Resource Estimate Report for the Teasdale Zone”, incorporated the significant REE mineralization in the Upper Reef and Intermediate Quartzite units as well as the higher-grade Lower Reef. The minimum vertical thickness was increased to 5.0m to accommodate the use of larger underground equipment as a cost-reduction strategy. The inclusion of all three mineralized units as well as the expansion of the minimum vertical thickness increased the resource tonnage for the Teasdale Zone to 14,435,000 Indicated tons plus 42,447,000 Inferred tons of uranium and REE mineralization versus 17,458,200 tons of uranium mineralization in the historical resource estimate. The total rare earth metal content was increased by approximately 6 times the uranium content.

Location

The town of Elliot Lake is located in northern Ontario.  By road, the town is 30 km N of the Trans-Canada Highway (Highway 17), 168 km W of the nickel-mining district of Sudbury, ON. 201 km E of Sault Ste. Marie, ON, the gateway to Michigan, USA, and 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.

Appia Energy Corp. changed its name to Appia Rare Earths and Uranium Corp. in October, 2021
