I'd like to clarify something about point 1. of jon_doe's post. The quantec geophysical survey did not narrow it down to the presence of either mineralization or water.

The response to these geophysical methods depends on the resistivity/conductivity and chargeability of the material. These properties can be influenced by the presence and chemistry of water in the pore space but also by changes in the physical and chemical properties of the rock (what we are looking for).

Sometimes alteration of the rock properties by tectonic processes results in mineralization (what we are really looking for). However, this is not always the case. There can be alteration without mineralization, which could generate a similar response in the geophysical survey.

In my opinion the importance of the core sampling results are that they indicate that the alteration AND the mineralization associated with it occur at depth.
