Perranzabuloe Mining District - Perran Iron Lode
OS Explorer Map 105: Grid reference SW765575 to SW807555
As its name implies, Perran Iron Lode is not the name of a mine or group of mines but rather the body of ore underlying an area of Cornwall. Akin to the Great Flat Lode of Camborne-Redruth Mining District, the Perran Iron Lode runs from the north of Perran Beach to one mile southwest of St. Newlyn East in the Perranzabuloe Mining District of Mid Cornwall. The lode can be followed running east a distance of three miles from Gravel Hill Mine through Halwyn, Mount, South Mount, Treamble, Great Retallack, Duchy Peru and Deerpark Mines. The primary ore within the lode is siderite, (iron carbonate) otherwise known as spathic ore, with some limonite (hydrated iron(III) oxide ) as well as the sulphides of zinc, iron and lead, namely sphalerite, pyrite and galena.
It may be best to describe the mines individually:
Little is reported about the next mine, another opencast operation called South Mount, otherwise known as Crows-an-Carne.
The next mine was Great Retallack, otherwise known as Wheal Mexico. It lies just to the east of Treamble Mine and worked No.1 Lode and No.2 Lode (or Trebellan Lode) from quite a few shafts. These were: No.1 Shaft, No.2 shaft, Derrick Shaft, Engine Shaft, New Shaft, Iron Pit Shaft and Stevenson's Shaft. In the period between 1858 and 1880, Great Retallack produced 10,826 tons of iron ore, 11,639 tons of zinc ore, 198 tons of 75% lead ore and 600 ounces of silver.
Deer Park Mine lies at the eastern end of the Perran Iron Lode about threequarters of a mile southeast of Rejerrah and half a mile east of Duchy Peru. The mine was worked as three opencast pits with very little in the way of underground mining. The shafts were: Boundary Shaft, Horse Whim Shaft, Engine Shaft, Winch Shaft, Barton's Shaft, Lead Shaft and Fence Shaft. It produced 267 tons of iron ore, 3 tons lead ore and 10 tons of blende for the period 1875 to 1879.
Now that 'World Heritage' status has been achieved Cornwall in Focus will monitor developments and learn how the mines of the Perranzabuloe Mining District fare within the overall Mining framework.
