Adit reworked as Wheal Lomax. Overgrown dumps can be found along the coast path from Porthleven to Loe Bar, with an adit visible in the cliffs below. According to Russell and Hutchinson (1927), Wheal Rose, along with the neighboring mines Wheal Penrose and Wheal Pool, are believed to be among the oldest lead mines in Cornwall, with records of their operation dating back to 1625. The primary lode at Wheal Rose runs nearly north to south magnetic and is exposed on the low cliff approximately three-quarters of a mile southeast of Porthleven (as indicated on the 6-inch ordnance map, 76 SW). The mine reached a depth of 54 fathoms, with the southern levels extending beneath the sea and the mine water being highly saline. The upper section of the lode comprises limonite and crystallized quartz mixed with galena, along with small amounts of chalcopyrite and blende. At greater depths, the limonite transitioned into chalybite (siderite), which was mined as an iron ore during the final working period around 1864. The galena contained approximately 60 ounces of silver per ton.
