The Coniston workings are sited in the south west of the Lake District National Park, below Coniston Old Man and Penny Rigg Mill.
Lake District Park adviser, Eleanor Kingston, said volunteers were needed to help with conservation and archaeological survey work.
It would give people the chance to "connect with their heritage" she said.
Copper was mined at the scheduled monument until the 1950s.
Over the next two years more than 150 repairs will be made and work carried out to stabilise structures.
Chalcopyrite, a copper iron sulphide often known as Fool's Gold, was used for 16th century weapons, coins and the hulls of ships.
German workers were brought to Coniston by Queen Elizabeth I to extract it.
At its peak in the 19th century the mine employed 600 people.

Snibston Discovery Museum, which is based at a former colliery, showcases the area's industrial heritage.
But the withdrawal of a £4m Heritage Lottery Fund bid has prompted fears within the museum community that the centre could be in danger.
The county council said the funding came with strings attached and Snibston was part of a wider review of museums.
The award-winning museum is the most visited in the county, but some of the buildings were included on English Heritage's most recent At Risk register.
The funding bid had been for a £5m project called Mining Lives, which would have improved the condition of the colliery buildings and increased public access to the site.
Mark Taylor, from the Museums Association, said: "I just hope they have thought this through and they have left room to change their minds.
"Because it seems to me that when you are going to get £5m to improve your flagship museum it breaks your heart if you have to send that back, especially if the real reason is that you want to close that museum."
The council, which needs to save to save £95m, said a review of the county's museums was taking place but there were no plans to close the centre.
A Heritage Lottery Fund statement said: "As well as providing support to address the extensive repair needs of the scheduled ancient monument, the project would have created much-needed training opportunities for local people.
"The decision not to take this project forward is therefore very disappointing."
It added: "Our concern now is that the colliery buildings remain at risk, and we look forward to hearing from Leicestershire County Council what plans it has for the future of Snibston and the Scheduled Ancient Monument."
The county council's deputy leader, Nick Rushton, said accepting the money would bind them to conditions which meant they would be unable to properly review ways of saving money on site.
"I just dare not take this £4m from the Heritage Lottery Fund at this moment in time," he said.
"I have a big review ongoing at the moment of all arts, libraries and museums. I have to guarantee to protect vulnerable adults, children and elderly persons and I have to save £95m."
A £450,000 Heritage Lottery grant has helped secure the future of a 400-year-old copper mine in Cumbria.
