GroundTruth Exploration has partnered with Groundradar to deploy UltraGPR technology on a variety of placer gold exploration projects throughout the Yukon.  UltraGPR offers a dramatic improvement over consumer-grade GPR systems in extremely rugged conditions.  Penetration depths to 40 m have been achieved through sediment containing some clays.  Most importantly, large surveys have been completed rapidly, reducing costs to the end client.
