United Mines (Gwennap United Mines) was the name taken by the company consisting of the former Ale and Cakes Mine, Wheal Cupboard and Poldory who amalgamated in about 1780. Later the group was expanded to include East Ale and Cakes Mine and Wheals Andrew (Friendship), Clifford and Squire, which all are located within a distance of about 1 km from United Downs. The United Mines worked mainly two lodes: the 'Great South Lode' and, a little further to the north, the 'Hot Lode', named for its extreme temperatures at greater depth.

In 1861, the United Mines were combined with the Great Consolidated Mines which ceased working in 1856, and which lay about 1 km further to the north, and included Wheals Girl, West Virgin, Virgin, East Virgin and Fortune.

The combined group was renamed Clifford Amalgamated Mines and continued, unprofitably, until 1870.


Note: Not to be mistaken for the St Day United Mines.
