Yes the top 100 metres or so of Batoto appears to be oxidised (but also well mineralized-which is wonderful because its soft and easy to extract and also has great metallurgy) to some degree -as per the paragraph near the bottom of thelast NR.
"The top +/-100 metres of the porphyry is usually highly oxidized but still contains widespread remnant quartz veins and iron oxides that appear to be former pyrite and chalcopyrite. Little work has been done at this time to ascertain the grades within this oxidized cap so the Company is currently driving two tunnels into the zone from the original old Santa Fe logging road where the West Zone was first discovered".
However the area where the bulk sample over 150 metes was taken completely in fresh porphyry.
I'll see if i can download a picture of the oxidized zone and one of the fresh (primary) zone for you.
