Found one unexplored mine head and some thing called a sasser airsolution didnt go further in its between the 2 hills bfore the waste tip workings and is semi flooded i could go down but it means bringin a few tanks and the drone and all the other crap i need.The aerial pictures are quite good, they give a wider visual perspective on the site than you could get from the ground. I think long ago they used to mine fullers earth around here but the mines have long since collapsed or been lost/quarried away.
