Hammer hits copper discovery at Overlander-Andy’s Hill
THE DRILL SERGEANT: Hammer Metals (ASX: HMX) has received results from drilling recently conducted at the Overlander-Andy’s Hill project area, within the company’s Mt Isa project hub in Queensland.
The results have come from drill hole OVRC024, which was located between Overlander North and Overlander South.
Hammer claims to have intersected a significant zone of disseminated copper mineralisation in the footwall of the Overlander Shear Zone, which remains open at depth.

The company explained the drill hole was carried out to provide a preliminary test of the anomalous copper geochemical trend between Overlander North and South.
The drill hole intersected mineralisation with a four-metre composite sampling returning a 116 metre interval averaging 0.34 per cent copper Cu from 44 metres to the end of the hole at 160 metres.
One metre resplit samples will be submitted for assay shortly.
“These drilling results are proving the potential of Overlander and Andy’s Hill to host a major IOCG system, as well as shear-related copper-cobalt mineralisation as defined at Overlander North and Overlander South,” Hammer Metals executive director Alex Hewlett said in the company’s announcement to the Australian Securities Exchange.
“Hammer’s focus will be using geophysical techniques to focus further drilling.”
The copper mineralisation in drill hole OVRC024 occurs in a rhyolite unit in the footwall to the Overlander Shear which hosts Overlander North and Overlander South.
It is also where results from Hammer’s previous drilling campaign included:
Overlander North
OVRC002
14m at 2.62 per cent copper from 76m;
OVRC004
9m at 2.58 per cent copper from 49m; and
Overlander South.
OVRC 010
12m at 1.2 per cent copper from 31m.
OVRC024 was part of the 20 hole, 2090 metre RC drilling program recently completed at Overlander North and Overlander South as well as the Pelican, Serendipity and Python targets south of Kalman.
Most drill chip samples have now been submitted to the laboratory with assays for some four metre composites and one metre re-splits pending.
The results in OVRC024 are consistent with drilling results achieved by a previous explorer located 500 metres along strike to the south which extended into the footwall rhyolite at Overlander South.
Hammer considers these results combine to provide evidence for the existence of a large zone of alteration and disseminated copper mineralisation over a strike length of up to three kilometres in the Overlander area.
Hammer’s preliminary RC drilling at Overlander North where it has extended into the footwall sediments also intersected anomalous copper-gold mineralisation and associated red-rock alteration.
Final assay results are expected to be received for the RC program soon.
