A £35m project aimed at transforming a derelict part of Cornwall is calling for volunteers to help restore a 108-year-old mine engine.
The Heartlands development in Pool, near Redruth, will feature accommodation and a large adventure playground.
The engine at Robinson's Shaft is part of the old South Crofty mine.
As part of the Cornwall Council-led development the Grade II-listed engine is being brought back to service.
It was originally installed in 1903 and worked for 52 years, but has remained dormant ever since.
The Heartlands team said the restoration was likely to take about four months.
Volunteers will be needed between July and October. They will also have the chance to gain a Construction Skills qualification.
Scott James, programme director at Heartlands, said: "This is a great opportunity to be part of the Heartlands story and Cornish mining history in a really hands-on way."
The development of Heartlands was made possible in 2008 due to a grant of £22.3m from the Big Lottery Fund and financial support from Cornwall Council.
