   Shaft of 8m to ledge with another 4m to a floor of horses and maggots. The entrance lies just downhill of the track and has been tagged with 859 in error.

   A fuller documentation and description has been published by ADEMCO as site AD-85 after exploration in 2020. The following is translated and edited from their report.
    The entrance has dimensions of about 2.5 x 2.2m. A pitch of 4 m drops to a ramp with a considerable inclination of earth, blocks and garbage. The galleries develop below the track. As we go down on the left side we have a small inlet with two small, blind pits without continuation. Down the ramp we come to a small vertical pitch of 3m that takes us to an elongated room of small dimensions where the cavity ends at 14 m deep.
