an important feature of porphyry ore deposits is their large tonnage. For example, an individual porphyry copper deposit can contain several billion tons of Cu at %, making these deposits the largest source of copper ore. Ideal for open pit mining, they are commonly found close to the surface and can be mined on a large scale at a low cost.

MVI excels at identifying copper porphyryrelated intrusives
To verify the potential for Magnetization Vector Inversion (MVI) to identify deep intrusives related to copper porphyry systems, veteran copper explorer Carl Windels has compiled several North American examples where the technique works.. Among the known deposits the geophysicist tested using the MVI method are the continent's most famous, including Bingham Canyon in Utah and Morenci in Arizona.
