THE DRILL SERGEANT: Corazon Mining (ASX: CZN) has completed a detailed ground gravity survey at the company’s Top Up Rise project in Western Australia, which has confirmed the TUR gravity feature as a significant geophysical anomaly.
The defined size of the anomaly has increased, to now cover an area measuring 10 kilometres by 6 kilometres under sand cover on the edge of the Gibson Desert.
Corazon said its interpretation of the geophysical data suggests:
– The gravity anomaly appears fault bounded and structurally controlled;
– There is no correlation between gravity highs and magnetic trends. Gravity highs may both conform to or cross-cut geological features interpreted from the magnetics;
– The gravity anomaly extends to the west and overlaps a major magnetic feature;
– The highest residual gravity anomalies are located in magnetic lows and/or interpreted faults; and
– Target depths are variable; it is expected both shallow (immediately under the cover of sand-dunes) and deeper drill targets will be tested.

“We are extremely happy with the results of the detailed gravity survey,” Corazon Mining managing director Brett Smith said in the company’s announcement to the Australian Securities Exchange.
“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 fact that parts of the anomaly can be tested quite easily, with inexpensive drilling techniques, is an enormous bonus.”
Corazon is currently preparing for the inaugural drilling program at Top Up Rise with heritage and work program clearances in progress.
Site access and the re-establishment of old exploration tracks have been initiated by the traditional owners, the Tjamu Tjamu Aboriginal Corporation.
The company has secured a drilling rig with the capacity for aircore (shallow soft-sediment drilling), reverse circulation (to 300m) and core drilling (to 1,100m).
All three methods of drilling are expected to be utilized during the drilling program, which is scheduled to commence in May.
