RE:RE:Breccia zonesThe rock should be the same sedimentary rock as everywhere else along the Keates-Lotto corridor.
It can be difficult to think of rocks as being elastic but under pressure and often heat many will warp, bend and contort into bizarre 3D patterns. Some layers are nonelastic and will shatter before they bend creating fold breccias. This breccia zone could have been an exceptionally brittle sedimentary layer which turned into a fold breccia during the continental collision. At a later date gold bearing fluids came through the Appleton fault and friends seeking a path of least resistance through the rock.
In this scenario this layer would become a stratigraphic target for further gold exploration which plays into the possibilty of large volumes and tonnages.
