Golden Deeps (ASX: GED) has commenced a diamond drilling programme which is testing a series of porphyry/volcanics hosted copper-gold targets at its 100% owned Havilah Project in the Lachlan Fold Belt Copper-Gold Province of central NSW.
Five to 10 holes for 1,260m to 2,500m of diamond drilling will test two types of copper-gold target zones at the Havilah Project:
- Three initial holes will test two zones of surface copper mineralisation identified at the Hazelbrook and Hazelbrook North prospects, where large soil anomalies have been identified with rockchip values of over 1% Cu associated with visible copper mineralisation (malachite and the copper sulphide, chalcopyrite) within the Ordovician Sofala Volcanics.
- Up to seven holes will test the strong sub-surface IP chargeability anomalies - which represent targets for copper (with gold) sulphide mineralisation within the highly prospective Sofala Volcanics, in the contact zone of the Aaron’s Pass granite
The strongest sub-surface IP chargeability-sulphide targets occur at the northern end of the survey where values of over 55 millivolts per volt (mV/V) were detected against background of less than 10 mV/V.
Another two strong IP anomalies occur to the south within the same corridor, including an anomaly that corresponds with a resistive gravity low - which could represent a porphyry intrusion related to the Aaron’s Pass Granite located to the west of the prospect.
The Havilah Project is a granted Exploration Licence (EL8936) located within the eastern Lachlan Fold Belt (LFB) near Mudgee in central NSW.
The company is targeting porphyry/volcanic hosted copper-gold mineralisation in a belt of Ordovician age (Sofala) volcanic rocks in the Rockley-Gulgong Volcanic Belt, which is part of the Macquarie Arc in the LFB - a major geological province known for world-class copper-gold deposits such as Cadia-Ridgeway and North Parkes
