md spruiking potential iocg discovery

Hello

My first post over in this neck of the woods, hoping someone might have a bit of time on their hands to have a look over the most recent information provided today by CZN

This interview is discussing the information contained in the announcement from 17/4/2013

News: Corazon expands Top Up Rise anomaly

Corazon’s Managing Director, Brett Smith, commented

“We are extremely happy with the results of the detailed gravity survey. It’s added significant definition to a large featureless geophysical anomaly.

Amplitudes of this magnitude are seldom seen, and we’re excited to be drilling this large target next month.

The TUR gravity anomaly has no coincident magnetic high,
a common feature of many IOCG deposits.

------------------------------------------------

What are possible alternatives that might account for a large & geographically continuous gravity high with no coincident magnetic high, other than IOCG??

TIA :)
