Scope of Project:
The purpose of the geophysical work involving non-seismic / magnetotelluric (MT) methods is to collect and compile geophysical and petrophysical data along, and around, the Metal Earth traverses. Questions being addressed are:
1. Can a petrophysical section of the Metal Earth traverses be built, that is consistent with the known geology (surface mapping and any drill holes) and the geophysical data, including the seismic data?
2. If this section can be built, does it provide indicators about the crustal structures and how they extend to the Earth’s mantle?
3. Do these structures reveal a potential source of metals to endow mineral deposits in critical areas of the traverses?
The anticipated outcomes are sections showing the conductivity variations as a function of depth and distance. The sections will be interpreted in a manner consistent with the other geophysical data (gravity, magnetics and seismic) and the known geology.
