This group of mines was formed in 1852 by amalgamation of Carharrack Mine, Poldice Mine, and Wheal Maid. In 1864, Wheal Unity, Wheal Gorland, and the Creegbrawse and Penkevil Mine were included. In 1870, the name "Poldice Mines" was adopted for the whole group.

Unlike the name suggests, most of the mines are located in Gwennap parish, except for Wheal Gorland (in St Day parish) and Creegbrawse and Penkevil Mine (in Chacewater parish).

Not to be mistaken for the Gwennap United Mines.
