AKA North Wheal Friendship and Prince Arthur Consols. A Lead silver mine on the western edge of Dartmoor which closed in 1877 and has the only standing engine house, at Job's shaft, remaining on the moor. This was nearly lost in 1954 when the Army was given permission to demolish it to make good on their earlier poor effort at nearby Wheal Friendship. It was saved by the intervention of A.K. Hamilton Jenkin and others and is now a national trust property.
Ref. Tamar Mineral & Mining Group.
Ref: Richardson P.H.G. (1991) Mines of Dartmoor & the Taymar Valley after 1913, Devon Books, Tiverton.

2 samples of galena have been tested for silver by mass spectroscopy but neither gave a result above 0.03%.

The coordinates mark the Job's shaft engine house.

Detailed Mineral List:

ⓘ Arsenopyrite
Formula: FeAsS
Description: Test need to be done to confirm Arsenopyrite and or Lollingite
ⓘ Cerussite

References:
ⓘ Native Sulphur
Formula: S8
Description: Forms tiny rounded sub-millimeter crystals.
ⓘ Pyrargyrite
Formula: Ag3SbS3
Description: So far only found on one specimen as a group of three translucent red divergent micro-crystals measuring to 0.3mm tall In close association with Tetrahedrite and Chalcopyrite in a Siderite matrix. Other associated minerals are Sphalerite, Lollingite, Pyrite/Marcasite, and Quartz.
References:
ⓘ Pyrite
Formula: FeS2
Description: Forms micro-crystal in cubic to octahedral habit.
ⓘ Pyrrhotite
Formula: Fe1-xS
Description: Forms platy hexagonal crystals to 5mm.
ⓘ Quartz

ⓘ Siderite
Formula: FeCO3
Description: Abundant the major vein filling cavities are commonly lined with well formed crystal to 5mm+
ⓘ Sphalerite
Formula: ZnS
Description: Mostly occurs as red-brown clevage masses in Siderite with other sulphides, uncommon as crystals.
ⓘ Tetrahedrite-(Fe)
Formula: Cu6(Cu4Fe2+2)Sb4S12S
References:
Steve Rust collection.Identification: SEM-EDS
ⓘ 'Tetrahedrite Subgroup'
Formula: Cu6(Cu4C2+2)Sb4S12S
Description: Found on a small number of specimens as metallic black masses to 2mm, and as very rare tetrahedral micro-crystals to 0.2mm, closely associated with Pyrargyrite and Chalcopyrite in a Siderite matrix. Other associated minerals are Sphalerite, Pyrite/Marcasite, Lollingite/Arsenopyrite, and Quartz.
References:
ⓘ Vivianite
Formula: Fe2+Fe2+2(PO4)2 · 8H2O
Description: Forms partly developed crystals, and as a thin pale blue crust resulting from the alteration of Pyrrhotite/Pyrite.
