The Ana Paula deposit, is associated with a large arrowhead-shaped intrusive body emplaced in
the Mezcala Formation.  The intrusive measures roughly 2.5 kilometres in diameter and is composed of
fine-grained to porphyritic monzonite to quartz monzonite.  The contact between the intrusives and shales
of the Mezcala sediments consists of hornfels which carries gold, silver and lead.  This represents a
different style of mineralization at a higher level than the Nukay gold deposits which occur in skarnified
limestones of the Morelos Formation.  The contact aureole around the Ana Paula intrusion and the
intrusive itself has been extensively explored by underground and surface rock sampling.  There are nine
adits in the area.  Sampling of the hornfels horizon both underground and on surface has returned
significant gold values with up to 22.57 grams per tonne gold reported from a 1.30 metre channel sample
in the La Terquedad adit.  In places, the monzonite also carries gold values so it is possible that there are
at least two deposit types in the Ana Paula area.  In addition to hornfels and granodiorite-hosted gold
deposits, gold may also be present in iron skarn on the contact between granodiorite and the Morelos
limestone unit that lies beneath the Mezcala sediments.




What that tells me is that the intrusions that were the genesis of all the gold in the area didnt come as far to surface and all the gold that could have been lost due to erosion or artisanal workings is still there in the limestone contact beneath the sediments.


lets get those drills spinning!
