Conceptual Cross-Section through the Thor Fault Zone
The figure on the left shows a schematic cross-section through the Thor deposit. The dominant feature seen on the section is the Intrusive Target, and is estimated to occur about 200m below the surface. its presence is based on geological mapping, petrographic work and most importantly ground magnetic surveys that discovered a large magnetic feature in 2008. Virtually all of the drilling at Thor has been focused on drilling the 2km long epithermal deposit that is shown on the left side of the cross-section, and occurs to depths of 100-200m below surface. A series of high angle reverse faults appear to truncate the epithermal veins at depth, creating a staircase effect down to the Intrusive Target. The upcoming airborne survey is designed to provide much more information about the Intrusive Target, and also to try and identify a prospective mineralized part of the porphyry body.
