There is a very handy tape measuring tool in the program.
Big Daddy to the nearest Black Thor zone is about 2.3 km or 1 1/2 mile.
Black Thor drilling intersects the first chromite layers approx. 160 metres below surface. The richest 35 % plus CR2O3 begins from about 200 m.
First Big Daddy chromite layers starts approx. 100 metres below surface. Richest layers start from 120 m.
Hole NOT-08-44 (Eagle 1) intercepted 2 nickle layers between 220 and 235 metres below surface.
etc. etc. etc....
Notster, you said, "if you go up NNE of Blackthor turn around and line up with Big Daddy one can easily see the directional trend SSW both above and below surface".
Where does that bring us, yep..... Not's Black Bird deposit. Do not look for it in the map, it's not just there yet :)
