Hammer Metals (ASX:HMX) has enhanced the gravity and magnetic target at Overlander North IOCG target at Mt Isa, Queensland, after completing inversion modelling of IP lines completed to date.
The company had started a program of 3D-IP geophysical surveying in mid-February.
IP chargeability iso-surfaces outline an anomaly that overlaps the top of the gravity and magnetic bodies between 100 metres and 300 metres below surface and immediately to the west of the Overlander North deposit where recent drilling returned 75 metres at 1.33% copper.
Geological mapping was also completed at Overlander which identified extensive magnetite alteration and secondary copper mineralisation at surface above the overlapping IP, gravity and magnetic targets
Two holes totalling 900 metres are planned initially to test this target.
Drilling will commence at Overlander and Hammertime this month.
The IP and geological mapping programs have now shifted to the Andy’s Hill IOCG prospect six kilometres to the south.
