Hi IW,
I began a post on this very concept during the week and planned to put it out this weekend.
The annotated drill plan below covers a number of ideas I have been playing with;

In a simplistic way the elevation appears to relate to mineralization at MDP and LB. As IW suggests the 1500m contour seems important. I had trouble working out the exact contours but put on blue at 1525 and red 1575m (I think). The best mineralization to date lies within the red but extends outwards.
The question Dazedandconfused asked last night is IMO related to this concept as well. In Mexico the concept of manto style mineralization is a common one. From my limited understanding manto mineralization is used for sub horizontal zones of deposits where the fluids have gone out along bedding or structures and often represent potential ore. In the case of MDP and LB the host lithologies are the flat lying Andesitic units of the Mesa Formation.
For anyone interested in some weekend reading I would refer you to the
Alacran geology discussion thread
and for more specific information on the Mesa Formation my post:
Mesa Formation in a regional context
Expanding the concept of elevation related mineralization:
MDP Norte is in a much lower topographic position as Haplo observed.
The rough colour coding of contour lines shows how Mesa De Toxicc could relate to the elevation of the known mineralization. Depending on dips and intervening structures MDT does look prospective on this simplistic basis.
There are property line issues if the higher elevations are significant.
Holes 17 and 18 show elevation is not necessarily a good targeting tool.
Other aspects that come from simplistic observations of the topo contours:
Three possible NW SE fault structures are shown based in part on the topography.
In the case of the middle one there are strong geological differences between MDP and LB. Tony R also mentioned a fault was a possible explanation for this.
It will be interesting to see what mineralization exists between LB and MDP to the west of holes 89, 94 etc. if such a fault exists.
The Holes with Cu intersections are deeper and more to the NE. Probably just a function of drill density. Too early to see if this topo interpreted fault exists and has any significance.

This post would be better in the Alacran geology discussion but things get lost in there.
