Where Welsh mining communities formed overseas

Where were Welsh miners recruited overseas?

A large Welsh community formed in Argentina, distinct from the Cornish hard-rock and northern English soft-rock networks discussed alongside it.

Argentina is named as a destination for a large Welsh community. Welsh and Cornish miners belonged to distinct regional networks within the international movement of specialist labour. The Welsh miners are described as somewhat earlier migrants than their Cornish counterparts. The immediately preceding remark about tin miners in Tasmania is separate from the answer about Welsh migration.
