2m square obvious walk in mine entrance Entrance


A 2m square obvious walk in mine entrance with muddy floor. The level splits after 30m but both ways soon end with roof collapses. The original 1970’s R.C.A. mine schematics show that the adit turns sharp right (east) and connects to the adit coming from the mine G.Remon (T87 Mazarrasa). T89 was revisited in 2018 and confirmed that both branches of the adit are fully collapsed and impassable. Total explorable passage is 51m.
