Airborne EM methods: be wary of relying on the tried and true
MARCH 8, 2013 EXPERTISE
Matching an exploration target with a geophysical technique can be tricky for an explorer, partly because there are so many options available and partly because there can be significant differences in rock properties even among the same deposit types.
