- Further air-core drill results highlight gold and copper-gold potential
- Maiden drilling returns anomalous zones and strong indicators of potential
- AC drilling tested a 4.5 km-long trend
- Follow up AC program scheduled to commence in mid-May.
Talisman Mining (ASX:TLM) has identified significant copper and gold upside in the remaining assay results from its maiden aircore (AC) drilling program at its East Peak Hill project in NSW.

The 95-hole, 5,546 program was completed across seven drill lines at East Peak Hill to test a postulated north-south magnetic feature, covering a strike length of 4.5km.
The features contain several north-northeast-trending structures, which are seen as key to the emplacement of gold mineralisation in the district.
Talisman’s MD, Andrew Munckton, said the maiden drilling has provided strong indicators of potential for both large-scale vein-style gold and porphyry-style copper-gold mineralisation
“The recently completed air-core drilling program at East Peak Hill was designed to target a series of interpreted andesitic intrusions and the highly prospective volcaniclastic/sediment contact in the east, where limited soil geochemistry has defined anomalous pathfinder minerals at the edges of the interpreted intrusive bodies,” he said.
“These intrusions – and their sheared and faulted contacts with the surrounding rocks – host a number of significant gold deposits at the nearby Tomingley Gold Mine, operated by Alkane Resources.
“The broad 400m and 800m spaced lines of AC drilling have provided an initial test of the target, which is interpreted as being analogous to the Tomingley structural position and nearby porphyry copper-gold mineralisation style.”
Mr Munckton highlighted line two of the initial seven drilled, which returned anomalous assay results within the oxidised portion of the geological profile.
“The intersections recorded in holes EPAC0001 and EPAC0003 show ore-grade gold mineralisation located in the targeted structural position coincident with an important geological contact. These results demonstrate that this zone is a fertile location for orogenic gold mineralisation.
“In addition, a broad zone of anomalous copper-cobalt-zinc with attendant gold-silver-arsenic-antimony mineralisation has been located within line seven. This metal anomalism sits within a horizontal zone of enrichment within the weathered zone above the altered andesitic intrusive and volcaniclastic rocks in this area.”
Line seven was drilled immediately north of a large geophysical feature where the andesite and volcaniclastics have apparently been demagnetised, potentially by a later secondary porphyritic intrusion.
“The follow-up AC program planned to commence in mid-May is designed to further evaluate these two exciting targets for vein-style orogenic gold mineralisation and porphyry-style copper-gold mineralisation, both found extensively throughout the district.”
TLM is steady at 9.9¢. Mkt cap $18.64M.
