Exploration – Polymetallic Sulphides Water column testing – efficient first pass exploration Locates evidence of active plumes (“vent smokers”). Uses natural ‘pollution’ to locate mineral fields • Rapidly cover a prospective regional area • Basis is that an “active vent field” may indicate a region where mineralisation may have been active in recent geological history and older, mature ‘ore bodies’ may occur ‘along strike’ or ‘along rift’

Then explore ‘along strike’ or ‘along rift’ for “mature” orebodies, in this case the Suzette field 2km to the north.
