Ancient lead mine situated in the valley of the Gannel river, this operation worked three north-south-trending lodes that intersected the valley just south of Legonna. The mine was active in 1846, marked by the installation of a newly employed engine and the sinking of a shaft to a depth of 20 fathoms. Expenses were shared with Wheal Dyke, which operated on the same lodes slightly further south. While there are remnants of old shafts on both sides of the river, the full extent of the mine’s workings remains uncertain. Hamilton Jenkin identified several dumps near the river and the now dismantled railway line, which were still recognizable as of 1958. Dines (1956) initially listed this mine as Wheal Rose, suggesting that New Wheal Rose, North Wheal Rose, and Old Wheal Rose might be alternative names, but these references actually pertain to entirely separate mines. This error was corrected in the 1994 reprint.
