This famous mine was formerly located in Gwennap parish but is now located within the parish boundaries of St Day. It lies within the Camborne - Redruth - St Day District as defined by H.G. Dines.

History:

Wheal Gorland's first recorded working was in 1792, but the lodes were probably known long before this date. In this working, the lode was showing prospects of being productive, and it was decided to erect an engine in 1795. At this time the lode had been developed to a depth of 40 fathoms. It was decided to sink the shaft a further 20 fathoms. In this working, the shaft was sunk to 100 fathoms, but even at this depth, no regular ore shoots had been found. The ore was inconsistent - sometimes very rich, then nothing - and the mine made a loss between 1792-98. At times in the early working of the mine, the ore was so rich in supergene copper minerals a guard was put on the ore wagons. From 1800 prospects seemed to improve, with production reaching a high in 1827 of 2,959 tons of copper ore.

After this date, a decline set in, and output dropped to 498 tons by 1838. In 1852 the mine was taken over by St. Day United group of mines, but it seems little or no work was done under the new owners. The mine received a brief reworking between 1906-09 when there was a surge in demand for tungsten and tin, which was found mostly at the granite/country rock contact. The last attempt at ore production at Wheal Gorland was in 1976 when the main specimen producing dump was removed to extract the tin ore (which is speculated to have only contained about 2lb of black tin per ton, a sad loss considering the value of the dumps to collectors). Prior to this date, the dump was being actively worked by amateur collectors for specimen material.

Since then there has been a failed attempt by collector/dealers to gain access to the Muttrell lode via Davies shaft. And when Wheal Jane was working (and therefore lowering the local water table by mine pumping), it was possible to gain access all the way down to the County Adit, but again not to the fabled Muttrell lode. It is believed now by local collectors that any access gained into this lode would probably be unrewarding as the ground from Davies shaft towards the Muttrell lode is like a not-quite-soft cheese and the stopes are likely to have collapsed.

Ore production

PeriodProduction
1792-982,500 tons of copper ore (estimate).
1800-045,907 tons of copper ore
1815-5140,751 tons of copper ore
1906-09164 tons of tungsten ore, 15 tons of tin ore, 18 tons of arsenic.


As of 2017 the site of Wheal Gorland around the former Bawdens Shaft (site of the specimen dump mentioned above) and Old Engine Shaft has now been developed as housing.
