Early post-medieval tin streamwork at Gonamena is a series of modified watercourses and associated earthworks created through alluvial tin extraction in the sixteenth and seventeenth centuries. The site preserves evidence of the small-scale hydraulic mining techniques employed during this period, whereby tin-bearing gravels in valley floors were systematically worked to recover tin by water washing. The landscape modifications visible at Gonamena reflect the organized exploitation of alluvial deposits that was characteristic of Cornish tin production in the early post-medieval period, when such streamwork operations complemented deeper shaft mining. These earthworks represent an important phase in Cornwall's mining heritage, documenting the transition between medieval placer working and the more intensive industrial practices of the later post-medieval era.
