Geophysics<br />

An array <strong>of</strong> geophysics tools can<br />

be employed <strong>for</strong> polymetallic<br />

sulphides given their physical <strong>and</strong><br />

‘metallic’ properties, including;<br />

• Resistivity<br />

• Self Potential<br />

• Magnetics<br />

• Induced Polarisation<br />

• Video camera<br />

• Gravity<br />

• Based on these surveys, the<br />

areal extent <strong>of</strong> an orebody can<br />

be determined <strong>and</strong> with gravity<br />

measurement, the mass or<br />

tonnage can be estimated.
