The gold content of igneous granitic rocks is usually invariably low and not known to be of any great economic value.
We are talking PPM here.

Having said that many are probably the sources of the gold, silver, and other metals which are secondarily concentrated in the fractures, faults, and shear zones in the feldspar porphyry.
Feldspar can be an indication of contact zones existence...... where Igneous meets Metamorphic rock.
This is where the higher concentrations of gold will be.

Look for these areas cracka....... where the granite meats the metamorphosed areas of rock, and target the mentioned fault and sheer zones to increase your odds of a find at close to surface level, rather than deeply embedded sources in the igneous.

Not sure what resources you have available in NSW, but Geovic is an excellent tool we use here in VIC to identify these types of zones.

Good luck mate

[QUOTE="Metamorphic, post: 185917, member: 3682"] The gold content of igneous granitic rocks is usually invariably low and not known to be of any great economic value. We are talking PPM here. Having said that many are probably the sources of the gold, silver, and other metals which are secondarily concentrated in the fractures, faults, and shear zones in the feldspar porphyry. Feldspar can be an indication of contact zones existence...... where Igneous meets Metamorphic rock. This is where the higher concentrations of gold will be. Look for these areas cracka....... where the granite meats the metamorphosed areas of rock, and target the mentioned fault and sheer zones to increase your odds of a find at close to surface level, rather than deeply embedded sources in the igneous. Not sure what resources you have available in NSW, but Geovic is an excellent tool we use here in VIC to identify these types of zones. Good luck mate ;) [/QUOTE]
