siemen response varies on material, and even if it's sulphide/s, it relies on distributions of sulphide/s and even then it relies on the dimensions of the anomaly - Siemen readings are the biggest red herring which retail gets conned by.

there's a reason they aren't considered material information.

anyway the EM anomaly is/was done by MLEM & FLEM which is done from the ground, not the air. which is good. airborne EM creates more false positives. the further away the instrument the less accurate reading you get (being in the air and moving vs on the ground)

tomorrow will be very interesting.
