[QUOTE="user 4386, post: 448131, member: 4386"] As much as a third of the gold mined from the "deep lead" gravels of Victoria actually came from fractures in bedrock underlying the gravels, not from the gravels themselves. And a lot of that got left behind in shallow alluvial mining (probably less so underground in leads because of the need for a level bedrock floor to run barrows and rails along). Some wider fractures were mined (rarely) to metres below the gravels, but most occurred within the top 30 cm of bedrock. [/QUOTE]
