Terry,

The ovoid was not "missed" on the first 5 of 6 holes.

FACT:
After the discovery, a ground mag/vlf/HLEM survey was conducted from the main gossan area, east to line 13+00E, SHORT of the ovoid. A systematic drill program moved from west to east testing a dyke-like conductor. The drill results improved as the program moved east and the geophysical surveys were extended to the east (then and only then over the ovoid). VB94-02 intersected 33.20 meters of massive sulfides with nearly 7% combined Ni/Cu! A geophysical consultant from St. John's, Newfoundland was hired to interpreted the new data during the Christmas break 1994-95 (an example of the early workers trying to be prudent). He spotted holes 6 and 7 based on a dyke-interpretation of the HLEM data because of the earlier drilling. The broad anomaly could have been interpreted both ways, I guess (just being nice), but it looked more like a depth limited wide-body conductor. Hole 6 was spotted on the basis of this report, to intersect the "dykes" at depth, but came up empty (undercut the ovoid). So the contractor's report was trashed and a scissor hole (07) was spotted. The rest is history!

Although this period was just before my tenure I compiled all the geophysical data reports and interpretations during my initial work. I must say Terry, that statement and its implication show a lack of class and I would expect better from someone with your experience! You owe the early people on that project an apology!
