Often, when a geophysical survey is acquired, a basic interpretation is performed, and drilling immediately follows. Then the geophysical data are filed away and forgotten. In the case of the Round Top Project, Western Alaska Copper & Gold Co. and Zonge Engineering have partnered to revisit the 1981-84 geophysics – review old data, re-interpret and reintegrate, and compare to new data acquired in 2010.
Using 3-D visualization of geophysics, geology and geochemistry, the data from the early 1980’s have been re-interpreted, the new zones of interest have been identified, as well as providing correlation to known mineralization. This paper will focus on the re-modeling of the induced polarization data integrated with surface geology.
