Since 2006 it has been part of the UNESCO World Heritage Site – Cornwall and West Devon Mining Landscape.

The mine is within the Aire Point to Carrick Du Site of Special Scientific Interest (SSSI) and the South West Coast Path passes along the cliff.

The first steam-engine was put to work at Carnyorth Moor (later part of the Botallack sett) in either 1795 or about 1810, depending on the source.

A visit by the Prince and Princess of Wales in 1865, when they descended the shaft, created a mini-boom in tourism, causing the mine operators to charge visitors a guinea per person.

[2] An increasing supply of tin – initially from Malaysia, Banka Island, and Sumatra, and in the 1870s onwards from Australia – along with a fall in demand for tinplate in the American market, caused the price of tin to fall, causing many Cornish mines to close.

[4] On 2 October 1883 the recently renewed setts, which extended over 2 miles (3.2 km) – comprising Wheal Cock, the Crowns, Carnyorth and Higher Mine – were put up for auction as a ″going concern.″ It included four pumping and three winding engines, two steam stamps, plus other appliances.

[10] The 1970s BBC television series Poldark was filmed partly in Botallack, using Manor Farm as Nampara.
