Ann: Kalkaroo Drilling Update , page-3

"The chemically reactive, 80-120m thick prospective sequence that is host to the Kalkaroo replacement style mineralisation is calculated to cover more than 700 ha in the faulted 'saddle' area that lies between the Kalkaroo north and south domes."

To put this in perspective, the area of ore body exposed (142 Mt) exposed in the Kalkaroo project open pit is approximately 42 ha (page 3 of today's ASX release).

This is the first time HAV has used the following references, so they must think they are onto something big (thing tier one assets):

"The geological model is similar to that proposed for other korld class copper provinces, most notably the Central African Copper Belt of Zambia and the DRC, and the Kupferschiefer in Poland and Germany."
