Iv'e seen some clay lenses on the face of a chalk embankment, round tubes of clay material c1-2 across in that case.......i can't remeber san gold using lenses before in the context of hinge..................fantastic news that the targetted parellel zone 0.5 lkm away has teh same geology, and they onlky have a bunch more of those to test.
prospect looks endless. or long (OTG)
