A gold nugget is a naturally occurring piece of native gold. Watercourses often concentrate the nuggets and they are recovered by placer mining, but they may also be found in residual deposits where the gold-bearing veins or lodes have decayed. Nuggets are also found in the tailing piles of previous mining operations, especially those left by gold mining dredges. They are never pure 24K in composition but rather about 20 to 22K (~about 83% to 92%). Nuggets are also referred to by their "fineness", for example "865 fine" means the nugget is 865 parts per thousand in gold. The common impurities are silver and copper.

Its hard to imagine things like gold or quartz being dissolved by water solutions, but if the water is hot enough, the pressure high enough, and the chemistry is right (acids, and other elements like sulfur are present), then gold, quartz and other things you don’t expect to see dissolving will go into solution.
The gold is derived from a series of small quartz veins which occur in shale in a 2 mile wide belt on a pediment east of the range front along the Majuba mountains.
The tendency for coarse gold to form in smaller veins is not a hard and fast rule and there are some large veins which have produced very coarse gold (like the 16 to 1 mine in the Allegheny District of California).
