Ann: Portia Processing Plant Treats First Gold Ore-HAV.AX, page-6

"....have identified significant gold in the bedrock beneath the interim sub-pit..."

Well that's the bit I liked. Significant is a significant word.

I seem to recall HAV flagging in an earlier announcement that they were re-designing the open pit to get earlier access to the gold ore. If I recall correctly, it was largely ignored by the market until confirmed in later announcements.

Worth re-reading this article: http://www.havilah-resources.com.au/pdf/MESAJ077008-011.pdf

In particular:

"Using a commercial laboratory was prohibitively expensive for Havilah at the time
and, in doing this work itself, Havilah learned an immense amount about the deposit and the
nature of the gold and how best to recover it in a commercial plant."

So when HAV says there is "significant gold in the bedrock", they have the experience and track-record that I'm inclined to believe it.
