In 1983, Carnon Consolidated Tin Mines Ltd. started to explore the old Wheal Maid workings. A decline shaft (not an adit) was driven, cutting three mineralized veins on a distance of 655 m.

This decline, extending in a south-south-easterly direction before taking a sharp turn top the north-north-west was abandoned in 1985 following the collpase in the price of tin.

In a depth of roughly 100 m, some levels of the old 'Whiteworks section' were cut, from where a number of interesting minerals was recovered.

The Whiteworks shaft was fitted out to be used as an emergency egress route from the decline.
