Hushing

A prospecting and extraction method in which a sudden torrent of stored water is released down a slope to strip away soil and loose overburden and expose the bedrock and any mineral veins beneath.

Historical usage

An ancient method, used by Roman miners and by later prospectors: the Romans applied it on a large scale to gold at Dolaucothi, and it remained in use for prospecting in British lead districts long after Roman Britain ended.

How it worked

Water, built up in a reservoir or leat above the target ground, was released in a single controlled flood; the torrent scoured away topsoil and gravel, exposing bedrock so any veins running through it could be seen and worked. The Romans used the method extensively for gold prospecting and extraction at Dolaucothi in Wales, supplied by an aqueduct system running some seven miles from the River Cothi, and hushing continued in use for prospecting long after Roman Britain ended.

Why it was used

Hushing let prospectors strip large areas of ground quickly, without hand-digging through soil and loose rock first, to find and assess mineral veins that gave no obvious surface trace of their own — a much faster method than digging trial pits across a whole hillside by hand.

Regional variation

Hushing is recorded across a number of British mining districts, but its most famous and best-preserved use is at Dolaucothi, Britain's only confirmed Roman gold mine, where the characteristic scoured gullies and hillside scars it left behind remain visible today.
