Brimpts Tin Mine

Overview

A Dartmoor tin sett on the southern slopes of Laughter Tor, west of Dartmeet, worked in two distinct sections -- North Mine and South Mine -- with origins in medieval streamworking and its last significant activity in the 1850s.

History

Brimpts Tin Mine lies on the southern slopes of Laughter Tor, running from there to just west of Dartmeet on Dartmoor. The sett is in two parts, North Mine (SX653751) and South Mine (SX669738), with origins in streamworking dating back to around 1500. Later, more organised mining activity is recorded in two main phases, 1787-1798 and 1849-1855, overlying and reworking the earlier ground. North Mine's shaft reached a total depth of 26 fathoms; its remains today include the Engine Shaft and an Adit shaft (also called the New Engine Shaft), a number of overgrown trial pits, low building remains, a collapsed adit and the remnants of dressing floors. A detailed history and trail guide has since been published by the Dartmoor Tinworking Research Group, and the site -- though on private land -- is accessible via the Brimpts Tin Mines Trail, established by Peter Hirst in the mid-1990s.

Geology

Tin of the Dartmoor granite; the lodes worked are not named on the record.

Workings

North Mine's shaft reached a total depth of 26 fathoms; surviving features include the Engine Shaft, an Adit/New Engine Shaft, several trial (costean) pits, a collapsed adit and the remains of dressing floors below the main workings.

Closure

No further significant activity is recorded after the 1849-1855 phase of working.

What remains

North Mine's shafts survive fenced, with low building remains, overgrown trial pits and dressing-floor remnants; the site is on private land, with the waymarked Brimpts Tin Mines Trail crossing it.
