Abstract
The Shea Creek uranium deposit is situated in the Athabasca basin, northern Saskatchewan, Canada. A number of TDEM (time-domain electromagnetic) profiles were surveyed in a variety of commonly used survey configurations at mainly two locations over the conductor associated with the Shea Creek uranium deposit using the IPHT - Supracon - Anglo American low-temperature superconductor (LTS) SQUID (superconducting quantum interference device). The LTS SQUID is a B-field sensor that effectively measures small secondary transient EM decays in a conductive earth due to a sudden change in the primary field of a transmitter loop located beneath, on or above the surface of the earth.
