3- Geophysics for Porphyry Copper Deposits- SW N. America- Mark Thoman, 2018

[@karhukivi]

The San Manuel deposit was detected with expanding Wenner-array IP/R (and 1-D horizontal layered earth interpretation) at a depth of 330 metres back in 1948 (Siegel, 1971). That was 70 years ago! The mine was operated during 1952-1999 and became the 700Mt largest underground copper mine during the 1980s with BHP-Billiton operation. We should never forget what methods worked in the past.
