Strange audio recordings taken at Heartlands during a private paranormal investigation in the former tin mine have been released to the public in time for Halloween later this month.

Investigators G.H.O.S.T. UK uncovered a number of ‘electronic voice phenomena’ (EVP) and other strange noises after leaving recording equipment running in Robinson’s Shaft engine house, visitor centre, mining exhibitions and the Red River Cafe (once the carpenter’s workshop) at the 19 acre attraction in Pool.

Voices include a male stating “Go and ask them... where the keys?” in a strong Cornish accent, a male and female voice saying “Alright? Bobbin’ Big Head!” in the Red River Cafe and a male voice saying “Ghost is in there” in the visitor centre.

Other noises included bangs, knocks, the sound of a horn in the engine house and the mentioning of names.

Heartlands contacted the investigators after staff and visitors had reported feeling uneasy in various areas of the heritage buildings, but were shocked at just how many EVPs were recorded.

Heartlands and G.H.O.S.T. UK have now released a YouTube clip of the original investigation and are inviting members of the public to take part in new paranormal explorations on two exclusive evenings – Saturday, October 27 and Saturday, November 3.

Visitors will discover more about techniques used by paranormal experts and mediums while taking part in their own investigation. Spaces are limited to 30 people each night.

The paranormal evenings are part of a week of events at Heartlands Ghost Haunted, which runs from October 27 to November 4.

Other activities include a spooky disco for kids, a film screening of Scream the movie, pumpkin carving, eerie archery and scary mask making.

Kate Turnbull, marketing manager of Heartlands, said: “After comments from visitors and staff about strange encounters in the heritage buildings, we decided to get a team in to check things out with some surprising results.

“There is something for everyone within our week of spooky activities, whether it’s attending a paranormal investigation, dressing up in a Scream mask and coming to our cinema night or bringing the children along for a bit of scary dancing at the spooky disco.”
