Comparing Sandfire's Degrussa VMS Deposit to DM1's Belele VMS Target, page-51

siemen readings are literally an arbitrary number and the more conductive/less conductive doesn't mean better/worse, it just means it is conductive and has NO bearing on geological prospectivity apart from confirming a conductive body.

you can literally have two identical mineral content bodies say 100mt of iron sulphides (both as worthless as each other), one Stratiform and elongate, one thin, narrow and steeply plunging and you will get completely DIFFERENT siemen readings.

stop taking these red herrings seriously.

that high conductance - greater massive content content you underlined tbh is a load of shite. it's "correct" enough to not be "wrong" but it certainly isn't "right".
