Early post-medieval tin streamwork at Gonamena is a series of watercourses and associated features resulting from alluvial tin extraction undertaken in the sixteenth to seventeenth centuries. The site lies within the tin-rich landscape of west Cornwall, where such streamworks represent the intensification of placer mining techniques that exploited tin deposits in valley floors and stream beds. The surviving earthworks comprise channels, leats, and disturbed ground characteristic of the tin streaming process, whereby water was directed to wash away overburden and expose tin-bearing gravels. This monument documents an important phase in Cornwall's mineral extraction history, when traditional streaming methods remained economically significant before being superseded by deeper underground mining operations in later centuries.
