I converted the UTM coordinates from CPQ's maps (Zone 14 in Northern Hemisphere) for drill holes CR-10 and CR-5 which are in the centre of the Repressa Zone and Rojo zones respectively.

CR-10 is located at 24 10 36.357N and 101 30 57.274W

CR-5 is located at 24 10 21.01N and 101 31 41.25W

If you use Google Earth and zoom in on the CR-10 coordinates to an elevation of 25,000 you can see a discoloured area shaped like the Repressa zone and a NW-SE feature that would be about where you would expect a surface expression of the fault.

If you zoom out to around 10 miles and scan around you can see parallel and radiating structures all over the area. Some of them are very large. Since surface topography is often coincidental with subsurface structures it point to a lot of structural activity in the area. So Jrichm99's conclusion about the extent of tectonic activity and possible fluid conduits (plumbing) is on the mark.

I wouldn't be surprised to see them fly an AeroTEM airborne IP and Mag survey over the property in the near future if the drilling holds up on the Repressa zone. Once the geology, geophysics, and geochemistry are known then can use them as indicators to hunt for.

In the meantime fly around the property with Google Earth and try to figure out what is there. BUT, remember we are looking a low resolution satellite imagery so don't read too much into those brown patches (the could be a field of old Cactus!).
