is there a geoligist in the house

I would like a geoligist interpretation of the following;

"At 950 m depth, the conductivity high trends north west for 1.2 km and is approximately 800 m wide."

In my way of thinking if all that area potentially contains copper it will be a very significant find. Depending on grade and length Xstrata will be drilling a lot more holes.

For those that may be interested this is a very good article on Olypic Dam http://www.southaustralianhistory.com.au/olympic.htm

It took WMC & BHP 12 years from 1975 to 1987 and $150M to prove the copper feasable. $150M in those years would probably equate to $450M
