Zonge International completed the CSAMT survey on December 4th, 2011.
A CSAMT survey was conducted over the anomalous area and outlined structures conducive to hosting gold mineralization as well as a resistivity low at depth which could potentially reflect lower plate rocks which commonly host significant gold deposits in Nevada such as Cortez Hills.
The particular electromagnetic method employed in this experiment is known as CSAMT (see Fig.
The Picsaint (Purely Inductive Controlled Source Audio Magnetotellurics) electromagnetic method introduced by Val d'Or Sagax has the power and sensitivity of CSAMT without the unwanted static effects created by the telluric line.
The company is also planning to test the CSAMT geophysical technique to identify potential structures associated with sulfide mineralization.
The 2011 CSAMT resistivity geophysical survey identified three potential feeder zones to gold mineralization, Sancos Central, Sancos Northeast and Sancos Southwest (see press release dated October 13, 2011).
Targets along the Corridor are developed from surface mapping, geochemical sampling, CSAMT and gravity data.
The CSAMT target to the north along strike from the growing Carlin-style mineralization is of the size and magnitude that could provide a strong win for us and Summit.
Some ground electrical geophysics (IP - Induced Polarization) has been run over the area, as well as an electromagnetic survey known as CSAMT (Controlled Source Audiorange Magneto Tellurics).
CSAMT together with passive magnetotellurics (MT) has been successfully developed for exploration of oil and natural gas resources.
