Between 1820 and 1852 Wheal Maid and Carharrack yielded 23, 552 tons of ore containing 1,542 tons of copper.
1852 Wheal Maid was amalgamated with Carharrack Mine and Poldice and worked as St Day United.
The northern section of the Carnon Valley is called the Poldice Valley. Poldice along with North Downs, Wheal Busy and the Unity Wood Mines were the great copper producers.
The introduction of the Newcomen engine in the early 1700's brought more copper mines, and there was a mine at Cusveth (Cusvey) in 1734. By the end of the 18th Century, there were at least 9 mines working here, they included:
- East Wheal Virgin,
- West Wheal Virgin,
- Wheal Girl,
- Wheal Maid,
- Wheal Fortune,
- Wheal Cusvey,
- Wheal Lovelace,
- Wheal Deebles and
- Wheal Wentworth.
In about 1780 these were amalgamated to form Great Consolidated Mines.
