Golden Deeps'(ASX:GED) assay results from diamond drillholes at the 100% owned Havilah Project in the world-class Lachlan Fold Belt Copper-Gold Province in NSW have produced thick intersections of copper and zinc bearing sulphide mineralisation, with significant levels of silver and gold.
The company believes the results indicate the mineralisation at Havilah is in close proximity to a large porphyry-sulphide system.
“The assay results for diamond drillholes HVD001 and HVD003 at the Hazelbrook prospect at Havilah have confirmed the discovery of extensive copper-zinc bearing sulphide mineralisation as well as zones of silver and gold mineralisation in the world-class Lachlan Fold Belt in NSW," CEO, Jon Dugdale, sa
"The high levels of zinc with the copper mineralisation at Hazelbrook indicate the mineralisation is potentially on the periphery of a large copper-gold mineralised porphyry-sulphide system, with similar geological characteristics to major deposits in the Lachlan Fold Belt such as the world-class Cadia-Ridgeway Project.
"Subject to further results from drilling and soil sampling programmes, we are planning to launching a new drilling program to test this exciting discovery of widespread, copper-zinc, silver and gold bearing sulphide mineralisation.”
Diamond drillhole HVD003, which tested the extensive Hazelbrook copper soil and rockchip (>1% Cu) anomaly, intersected patches of semi-massive copper (chalcopyrite) and zinc (sphalerite) sulphides as well as vein and disseminated sulphides across an 84m zone in the targeted Sofala Volcanics.
This 84m zone assayed 0.14% CuEq (0.08% Cu, 0.18% Zn, 0.43 g/t Ag) from 84m downhole.
The Cu-Zn-Ag mineralised sulphide zone intersected in HVD003 is open to the southwest and at depth. Felsic dykes intersected by HVD003, parallel to the northeast trending anomaly, and the predominance of zinc, with silver, over copper and gold in the intersection, indicates the mineralisation is on the periphery of a mineralised porphyry system – with copper and gold grades expected to increase closer to the intrusion.
Mr Dugdale said the exposure of altered and mineralised volcanics in EL9114, and the large magnetic anomaly associated with the mineralised volcanics, indicates potential to double the footprint of the Havilah mineralised system to more than 5km from north to south.
