The Siemens numbers was a red flag., page-73

For comparison of Siemens readings,
here is a great one posted today by @KeenDog which shows ESR readings of 11,000 are not near as good as other Ni explorers at 20,000 - 60,000 siemens -

ST GEORGE MINING- ANN 21/10 Two very strong off-hole electromagnetic (EM) conductors – modelled with conductivity of 49,000 and 16,200 Siemens respectively – have been identified by the downhole EM (DHEM) survey in MAD184

LEGEND MINING ANN 21/10 DHTEM identifies 25,000-70,000S off hole conductor from RKDD025

POSEIDON ANN 1/10 The newly modelled EM plate measures 54m north-south along strike and 22m in the sub-vertical plunge/dip direction with a very high conductance of 58,000 siemens. The EM plate is located on the basal contact position. It is interpreted that this, very high conductance, plate is likely to represent the presence of massive nickel sulphides.

POSEIDON ANN 12/10 Of the new plates identified in this survey, one is a high conductance anomaly of 20,000 Siemens and given there are no known other conductive sources to provide false anomalies at Black Swan, this new anomaly is interpreted to represent massive sulphides.
