Great Flat Lode

The Great Flat Lode is a mineral-bearing body of rock under the southern granite slopes of Carn Brea south of Camborne in west Cornwall, UK.

The Great Flat Lode lies under the southern granite slopes of Carn Brea and so named because the tin-bearing rock was at an unusually shallow gradient of about 10 degrees to the horizontal.

In other parts of Cornwall mineral bearing lodes lie at between 60 and 90 degrees to the horizontal.

Its small gradient allowed for optimal location of the mines.

[1] Many of the mines amalgamated and continued production until the First World War.
