I don't know... Read the announcement; "oxidized (carbonate) mineralization within the quartzite". You can interpret that as
a) "We hit mineralization, it was carbonates, we can't tell you it's zinc, but it did contain some sulphides."
or
b) "We hit something, we are hopeless incompetents and we hope the lab gets back to us before armageddon."

Also, they said 3 of their 4 holes hit mineralization. The 4th hole didn't hit "clearly identifiable base metal sulphide or oxide mineralization". Again, you can take it two ways;
a) "We have 3 holes with, and one hole without, clearly identifiable base metal oxide mineralization."
b) "We hit something, we are hopeless incompetents and we hope the lab gets back to us before armageddon."

It depends which way you read things, I guess. On the one hand, we should be if not excited, placated; on the other hand, yes, you're right, its typical behaviour.
