Charles Thomas (1794-1868) was a mining agent and share dealer in Camborne, Cornwall, in the United Kingdom. He was an advocate of deep mining. Charles Thomas was employed at Dolcoath Mine in Camborne from the age of 12 and nine years later was made an underground agent. By 1832 the mine's previously rich deposits of copper ore were substantially worked-out and the mine was in danger of closing. Thomas believed that rich deposits of tin ore would be found below the lowest levels of the mine, and tried to persuade the shareholders of this without success.
