Great ann and great posting today - thanks.

IMO @BaltasarG got it right. And I will just add this.

Take a look at the graphic in his chart and check those major faults which are believed to be related to the mineralisation. Note the kinks and bends, particularly near Chuscil and Ciebal. What caused the ground containing those faults to bend like that - a large upthrusting intrusion maybe ?? A mineralised porphyry intrusion perhaps ?

And if that is not so whatever bent those faults further cracked and smashed the rocks allowing a path for the mineralised fluids to reach surface.

Then look at the many cross cutting minor faults in the region of the kinked major faults.

Finally what if I were to say I can see two separate but incomplete rings of mineralised zones, both related to an intrusion which could explain the bending of the faults ?

Just me thinking out loud, so DYOR, as usual.
