Please correct me if I am wrong.

The "anomalies" on the left map on NOT's property are from an electromagnectic survey, hence, conductors. The "anomalies"  on the right map on FNC's property are from a magnetic survey and hence, should only be interpreted as areas of bedrock with a high magnetic signature (i.e. ultramafic rocks) which may or may not be mineralized. I would strongly suspect that DE1 and DE2 are both characterized by a signature of "coincident" EM and mag anomalies. The VMS mineralization found to date was probably characterized by EM anomalies alone.  My interpretation is based on the nature of the mineralization and host rocks found to date.
