I can name that "tune" in 3 words, Major Crustal Structure. The view from 1000 Km above Mexico is dramatic... at 100 Km you can imagine(see) The relationship with Penasquito... dramatic.
How did I go there? Google Earth! I have Google Earth images to illustrate MY interpretation. Other should look and draw their own conclusions!
How did I locate Camino Rojo and Penasquito? From UTM coordinates from the 1.) Canplats Drilling map location of CR-1 (Represa) and the 2.) 2005 Glamis Feasability study for Penasquito.
The bigger the plumbing system... this is a BIG structure. It is not hard to bring it right through Represa either.
I emailed Canplats and the reply was; they have been looking too!
