2. Check the natural cracks and lines of the quartz rock. Gold often occurs along the natural linear structures of quartz rock, or its natural cracks and lines. It is easiest to spot in …
Density- Measure the volume and weight of a gold-bearing stone. Quartz has a density of 2.65 g/cm³, while pyrite sits at 5 g/cm³. Gold will be 19.3g/cm. Without exact measurements, this test is more promising than conclusive, but gold will stick out like a sore thumb if you have another, similarly-sized piece of quartz for comparison.

The gold-bearing veins and shear zones have three principal orientations: (1) N. 5°—15° W., with dips ranging between 80° W. and 80° E.; (2) N. 0°—15° E., generally with dips ranging from vertical to 70° W.; (3) N. 20° W., with dips ranging from 60° W. to 85° W.
If it is quartz multiply it by the SG of Quartz 2.65. Take that weight away from the dry weight of the rock and the weight left is a rough estimate of the gold in that specimen. Remember, this is definitely not as accurate as the first method and …
There are numerous quartz reefs still showing in Victoria which are absolute duffers - no gold, in fact you can walk across many gullies with quartz runs that are gold barren. The coloured quartz - rose etc, is also an indicator that the quartz was subject to mineralisation which is a positive indicator but still no guarantee. Beagleboy Milan
This can be an indicator of gold. Iron Staining & Gossans: Not all veins produce much quartz – gold bearing veins can consist of calcite or mostly sulfides – which often weather into iron stained spots when the pyrites convert …
