You mentioned in another forum, that you are an experienced VMS geo. I am not a geo but am a s/h with some faith in ALY's potential. Could you provide some insight into Audio-Magnetotellurics Survey (AMT) and the potential to find base and precious metals as opposed to VTEM survey.


"Audio-Magnetotellurics Survey
An orientation audio-magnetotelluric (AMT) survey was completed in May 2011 to assess the quality and depth penetration of previous geophysical surveys as well as applicability of the AMT technique to exploration of base and precious metals at Magnus. Magnetotelluric methods can detect conductors linked to base metal mineralisation as well as map variations in resistivity associated with changes in lithology.

AMT data was acquired along two parallel, offset profiles that in combination form a continuous profile across the prospective stratigraphic sequence on the eastern side of Magnus (Figure 2). Each profile was approximately 4 km long with AMT data acquired at 100m station spacing. The profiles coincided with profiles from previous VTEM, MLEM and gravity surveys enabling direct comparisons to be made.
Depth conductivity sections for each of the AMT profiles successfully delineated major geological packages and their boundaries, defined conductors that correlate well with the VTEM, gravity and known geology, and resolved new features that were not detected in the VTEM survey. In particular, the AMT conductivity depth sections image a number of interesting anomalies including significant conductors at depths over 300m within the Narracoota volcanic sequence (Figure 3).

Of the geophysical methods applied to date at Magnus, AMT appears to be the only one that has provided good correlation to mapped geology, imaged conductive responses within the resistive Narracoota volcanic sequence and has the deepest depth of penetration to over 600m".
