This is an example of the I.A.Recordings Industrial Archaeology MapNotes for one British Ordnance Survey 1:50,000 series map.

We have produced these notes over the years for our own use as a concise digest of industrial sites in a given area.

Map 203 covers Land's End, the South-western extremity of the Cornish peninsula. As you would expect, most of the historic industry in Cornwall is tin or copper mining!

Each numbered entry has a National Grid Reference (NGR) code, such as SW 697 494. This code is the coordinate system of the British Ordnance Survey (OS) and may be used to locate a site on any map printed with an NGR grid. For more information on OS maps, see the Ordnance Survey web site.

since moved to Geevor tin mine museum & extensively restored.

12) SW 368 346 Pendeen; Levant Mine. Mined copper & tin from
c.1820 until ‘knocked’ in 1930. Geevor took over in 1960's &
plugged hole 200m out to sea where a stope from the 40 fathom
(73m) level had got too close to the sea bed. Levant workings then
connected underground with Geevor but results were poor. (Geevor
later sank decline to >610m to work very good tin ore under Levant's
old levels!) Levant levels extended 2.4km out to sea at depths of
325m, 618m, and 475m. In 1987 Skip shaft with wood-enclosed
headframe for electric winder still in use as ventilation for Geevor
Mine. [mmme] {Update} Geevor mining ended 1990.

 1835 45" pumping engine house, one of oldest in Cornwall.

 1840’s Michell whim Engine House preserved by the National
 Trust. Beam Engine, unusual in that both beam & flywheel are
 inside, possibly for shelter from Atlantic. Designed by Francis
 Michell. Built by Harveys of Hayle ~1840 (27" x 4'). Said to be
 oldest engine still operating in Cornwall. Cast iron beam may be
 from even earlier engine. Saved from scrapping 1935 by Cornish
 Engines Preservation Society which became Trevithick Society.
 Restoration begun 1985. Support column added under wooden cross-
 timber during restoration. Occasionally in steam. Winding drum
 outer bearing rusted solid in salty atmosphere, so now rotates with
 drum inside cover! Condenser cooling water in walled pond.
 Viewing used to be by arrangement with Geevor Tin Mines Plc.

53) SW 7239 5046 St. Agnes; Gooninnis or Gooninis mine, sunk as a
trial starting in 1873 with aim of reaching the rich West Kitty lode.
In 1899 a 12" horizontal winding engine by Holman Bros. of
Camborne was installed. This marked the start of the most active
period at the mine. The short surviving chimney stack was for the
whim engine boiler. By 1901 the large Cornish engine house (still
standing today, with an adjoining stack) had been built and the 50"
beam pumping engine was moved from Trevaunance mine to here.
The shaft was sunk to 132m below adit without hitting the lode.
Mine abandoned 1903. In 1910 the bob was removed to
Castle-an-Dinas near St. Columb Major and the pumping engine moved to
Goonvean China clay works, near St. Austell, where a new bob was
added. (The engine is still there, derelict in a roofless engine
house.) The engine house chimney was struck by lightning in the
winter of 1992-3. Note: The buildings are on private property
and part of a working farm. [vis, ASAP, EX3]
