Mining company reports often mention geophysics programmes and the terminology is usually not explained. I have listed common techniques and attempted to explain each simply. The most important thing to remember is that none of these techniques identify the location, grade or volume of mineralisation. Rather, geophysics identifies a likely location for mineralisation for the geologist to examine further. Any geophysical target should be initially followed up by boots on ground geology (even targets beneath cover).

This article was written by Snowden’s Global manager, Tarrant Elkington. It is easy to forget, or take-for-granted, the foundation elements for your area of expertise. The blog looks at patient zero for mine optimisation. I was in a meeting many years ago working through some optimisation mathematics on the whiteboard with some colleagues. It looked something like this – please don’t worry about the detail.  IV_a=UGDV_a-OPDV_a  UGDV_a=frac{r_a-h_u_g-m_u_g}{(1+d)^u^y}$  OPDV_a=max(frac{r_a-h_o_p}{(1+d)^o^y},0)+frac{v}{(1+d)^o^y}$ Midway through this review, my boss at the time saw one of our clients appear at a window and he jumped up, bringing him into the room. He pointed enthusiastically at the equations and said: “Look at this thing on the board…  this is going to be a … Read More
