I was in the Bissoe cycle cafe over the week end when I overheard a conversation about a mystery tunnel below the Nangiles spoil heap. have passed the above the spot probably scores of time over the years, I was quite intrigued.
I had always though that the adit to Nangiles was down by the County Adit Portal ? Yesterday being in the area again I quickly found the adit "featured in the conversation" Edited Can anyone tell me what each "one down by CA portal" and the "new to me" one are about. also a small opening some 50 yards or so Eastwards of the new one in the undergrowth ,
