Perched on cliffs overlook Trevaunance Cove sits the remains of Wheal Kitty mine. Mining has occured all around the St Agnes area since the time of the old men, but this particular sett was first documented in 1758.

The mine was next mentioned under the names Pink and Goonlaze in 1778, with reference made to ore remaining unsold on the surface, potentially due to a lack of stamping equipment. By 1838, functioning as a copper, tin and iron pyrite mine, Kitty had reached a depth of 50-fathoms and employed 258 people.

At some point, the separate workings dotted along this patch of coastline, including Wheal Pink, Goonlaze and Wheal Bottle/Vottle were all amalgamated into one. Penhalls, a larger neighbour, remained a separate enterprise until 1904.

In 1852, the mine was reopened following a boost in tin prices, sparking celebration throughout St Agnes. The mine remained fairly prosperous until the 1890’s; in 1896 all of the pumps were stopped and work concentration on the area above adit. The following year work had ground to a halt.

The early 20th century saw more work being done on the site. In 1907, Wheal Kitty opened alongside neighbour Penhall’s mine, which had been idle since 1888, as Wheal Kitty and Penhall’s United Ltd in 1907 along with Gooninis mine. This venture came to its end in 1919.

Another attempt was made in 1926 to connect Wheal Kitty, Polberro and Wheal Friendly workings; this was completed in 1929. However, by 1930 most of these sections were exhausted and work was transferred over to the Polberro area, focusing on Turnavore shaft and Wheal Kitty stopped work for the final time.
