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 2017

  • No work is proposed for 2017. EM and gravity have been completed over the entire project and the claims are in a drill ready state. The project is in good standing until 2029.

Historical Work

  • In late 1970’s to early 1980’s the property was covered radiometric prospecting, lake sediment sampling, EM surveys and drilling: the northern part of the property has been drilled by 23 holes (3055m.). The conductors to the south were not drill-tested. Uranium mineralization (0.088% U3O8 over 4.02 m with 0.42% U3O8 over 0.36 m) and (0.068% U3O8 over 2.52 m) was intersected.
  • Forum acquired the property in 2006 and completed a horizontal loop EM survey and 6 drill holes for 824m. Weak mineralization was encountered along the C3 conductor between line 7200N and line 8400N.
  • Forum drilled two holes, COS-07 and COS-08 (347m) in 2007 at the south end of the property. Graphite and weak alteration were intersected in these holes. A ground gravity survey then covered the entire property in 2010 and the project once again lies in a drill ready state.
