The key thing to think about is how permeable the rock is - whether water can infiltrate or not. If the water cannot infiltrate, it will stay at the surface and will travel downhill. The steep slopes at Carding Mill Valley would mean swift movement down to the Ash brook in the valley base. This has a knock on effect on the river discharge.

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …

Alluvial/Placer gold deposits are gold-containing sand-mixed sediments formed after long-term weathering of vein gold deposits.Alluvial gold mining means mining from land surface or river or underground. Gold is in a free state in the sediments, and the difference in specific gravity between sand and gravel is obvious.
