Ownership:Forum 65%; Privco 35%
Stage:Highly Prospective; Drill Ready
Size:730 Ha
Location &
Regional infrastructure to the properties is good with nearby year-round road access (Highway 914 to Key Lake is 5km away), readily available power nearby, and close proximity to Cameco’s Key Lake uranium processing facility.
This project covers the southwestern extension of the graphitic conductive unit that hosts the Key Lake deposits.
Proximity to
Cameco’s former producing Key Lake mine, which extracted over 200 million pounds of uranium by open pit methods at an average grade of 2.3% U3O8 from 1983 to 1997, is located nearby to the north of the Costigan property.


  • Exploration focus is on discovering basement-hosted type uranium deposits similar to Millennium, Eagle Point, Sue C, Triple R, Roughrider, and Arrow, which can extend down to 900m below the unconformity.

Proposed Work Programs for 2019

  • Future work has been deferred until market conditions improve.

Historical Work

  • The project is drill ready having EM and gravity surveys completed over the entire property. The project is in good standing until 2029.
