Vitifer Mine (Birch Tor and Vitifer)

Overview

Birch Tor and Vitifer, either side of the Redwater Brook below the Warren House Inn on Dartmoor, was probably the largest and most productive tin mine the moor ever had — the last of Dartmoor's tin mines still working when it finally closed in 1925, after a documented history stretching back to at least 1750.

History

Vitifer, on the west side of the Redwater Brook valley, and Birch Tor, on the east, were originally separate mines, first documented as 'Vitifer Mine' in 1750 and 'Burch Tor Bounds' in 1757, though the site had already been the centre of extensive surface tin streaming and opencast working since medieval times or earlier. For most of their working lives the two mines were run under shared management and are usually treated together. By the 1780s Vitifer was being operated by the Dartmoor Mining and Smelting Company, employing around 40 men by 1796, and it went on to become probably the largest and most productive tin mine on Dartmoor: between 1852 and around 1928 the combined workings produced 1,177 tons of black tin. Mining continued, with interruptions, until the mine's final closure in 1925, by which time it was the last of Dartmoor's tin mines still in production.

Geology

The mine worked tin-bearing veins and stream deposits within the granite-related Dartmoor orefield, the same hydrothermal mineralisation system worked across Cornwall's tin and copper districts to the west.

Geological setting: Hydrothermal Deposits (well documented example), Veins and Lodes (well documented example)

Workings

Workings included both underground vein mining and extensive surface stream working and opencast pits; between 1852 and around 1928 the mine produced 1,177 tons of black tin, the dressed and part-refined tin ore ready for smelting.

Closure

The mine closed for the final time in 1925, the last of Dartmoor's tin mines still working by that date.

What remains

Ruined mine buildings, fenced shafts, flooded workings and extensive spoil from stream working and opencast pits survive across the Redwater Brook valley, among the most extensive tin-mining remains on Dartmoor.

Abandoned workings can be dangerous — unstable ground, uncapped shafts, flooding and bad air are common even where a site looks safe from the surface. This entry describes history and general location only; it is not an access guide.

Recorded claims

Individual factual claims, each attached to the source(s) that support it below. Where sources disagree, both are kept.

• Vitifer was probably the largest and most productive tin mine on Dartmoor, producing 1,177 tons of black tin between 1852 and around 1928, and remained the last of the moor's tin mines still working when it closed in 1925. ^1,2
• The site combines underground vein mining with extensive surface stream working and opencast pits dating back to medieval times or earlier. ¹
