AbstractThe primary objective of the high-resolution survey was to offer a detailed subsurface image of the complex P2 fault zone, hosting the world's largest high-grade uranium deposits. Raw seismic data have low signal-to-noise ratio; nevertheless the implemented processing procedure considerably improved its quality. Interpretation of the two lines integrates all available background information such as regional geology; structural, stratigraphic, and diagenetic features associated with the borehole information including stratigraphic and petrophysical properties; and seismic analogies for the basement from other high-grade metamorphic terranes.

The resulting interpretations generally agree with previous geological knowledge, but add new exploration insights, such as: 1) the complex 3-D geometry of the P2 fault zone, 2) the existence of additional dekameter-scale, fault-controlled structures associated with the P2 zone, 3) syntectonic deposition of the upper parts of the Manitou Falls Formation in this area; and 4) the internal architecture of
the metamorphic basement.
