An intersect from 80 to 90 meter on a 60 degree hole is a 70 - 80 meter DEEP intersection which is well in the ballpark of the accuracy of interpreting geophysics. Estimating the depth and horizontal position of an anomaly is a very imprecise science with a degree of hocus pocus thrown in (the interpretation of the results).
They may still hit another intersection in the targeted 100-150 meter depth but I suspect the anomaly will be explained by the massive sulphide horizon they already hit.
12 meters of massive sulphide would given a very strong response. If it is a VMS deposit the good thing is that they tend to have both length and depth so there is some real tonnage potential. Assuming no major faulting/displacement they also tend to be fairly easy to delineate.
The guys and gals that hold WSR/MTX should be happy campers over the next month or so as the results come in.
