Australia and the small Dolgellau Gold-Belt of Wales, United Kingdom. Nuggety slate-hosted gold-quartz reefs are characterised by the presence of highly-localised, erratic occurrences of coarse-free native gold (Johansen, 1998; Dominy et al, 1997; 1999). Large variations in grade ranging from <0.1 up to 8000 g/t are common.

It's worth noting here that dissolved gold is basically real gold in liquid form. During this process, the liquid reacts to its environment and eventually materializes in the fissures and cracks of various minerals, like quartz for example. Similar to gold, quartz is a 'mineral fluid' which travels upward and solidifies into its mined form.
