Cornish tin-streamers and the Australian gold rush: technology transfer in alluvial mining

The Cornish are known around the world for their mining skills. In the 19th century the migration of Cornish mining families created a diasporic community with settlements in the United States, Mexico, South Africa and Australia centred on copper, tin and gold mines. While the Cornish are generally associated with underground mining, recent research in Australia suggests that ancient methods for working surface tin deposits played an important role during the gold rush. The identification of Cornish tin-streaming as the source of alluvial mining technology in Australia sheds light on a little-documented branch of mining that has played a significant role in shaping the landscape of goldfields regions.
