You are right Sculpin, the zone names don't seem to always correspond to the proper lines. But the lines & 1st priority drill targets (Figure 2-34) do seem to make sense (as far as I can see), and line up.

I've heard lots about this T8 Anomally, but man, this T10 looks pretty good as well. From approx Line L4350N down to Line L3400N, and seems to almost blend in with T7? But take a look at Line L3750N (Page 82/185), it appears to be approx 900M wide, and unknown depth??

Never ends, how much you can keep looking at these, and continue to learn more. More positive as well!
