This is pure conjecture on my part but Prof. Mungal did describe the geology of Noront Eagles as a magma flow and surmised that such a geological structure could be several kilometers in length. Now this magma flow happens when molten rock far below the earths crust which is under extreme pressure, squirts through a weak point (or points) in the crust. It would be reasonable to think that this pressurized ooze would burn and force it's way through in an erratic manner. Is it such a stretch to think E1 and AT1 are connected at depth? Or for that matter the other anomalies are connected? The RED LINE on the mapping seems to connect some dots and suggest a common geological occurance. God only knows what minerals were in the original magma but we know that they have different melting points and densities. As the magma flowed, the surrounding host rock absorbed minerals when compatible. Denser minerals precipitated out when conditions permitted. Drops in temperature changed the physical state of minerals in phases. For these reasons, different sections of the magma flow have different assays. There are common mineral groupings in all the ROF properties but they are also different. JMHO.
