Discovery International Geophysics carries out TEM surveys using the Supracon AG high-temperature (liquid nitrogen) SQUID developed by the Institute for Photonic Technology (IPHT) in Jena, Germany.

The Supracon HT SQUID is touted as the most sensitive B-field detectror commercially available.

Discovery International conducted surveys last year in Saskatchewan, B. C., Manitoba, Quebec, and Minnesota for uranium, copper, zinc and nickel deposits.
