On Sunday 2nd July 2017 Mendip Cave Rescue were contacted by Corsham Fire & Rescue to assist with an incident in Box stone mine. A group of three explorers had entered the mines via the Back Door entrance and made their way through the system to Jacks entrance, where their exit was blocked by a large gate recently installed by the landowners. They were unable to retrace their steps, but instead were able to get mobile phone reception through the bars of the gate and ask for assistance. Mendip Cave Rescue have a small team of experienced local cavers who were called to the scene and they were able to enter the mine via a nearby obscure entrance and escort the three explorers to safety.
