Golden Deeps (ASX:GED) has intersected significant sulphide mineralisation in all three completed diamond drillholes at its 100% owned Havilah Project in the Lachlan Fold Belt Copper- Gold Province of central NSW.
The third hole of the programme tested the Hazelbrook target where an extensive northeast-southwest trending copper-zinc soil anomaly has been defined with rockchip values of over 1% Cu.
The hole intersected a sulphide mineralised zone from 85m to 119m which included patches and stringers (averaging 1-2%) of the copper-sulphide - chalcopyrite and the zinc-sulphide - sphalerite. These patches occur within extensively altered (Ordovician) mafic volcanic/volcanoclastic rocks with disseminated chalcopyrite-sphalerite-pyrite mineralisation which occurs from 85m to 166m (over 80m).
The mineralisation aligns with the surface soil and rockchip copper-zinc anomaly, striking northeast, dipping to the northwest, and the drilling intersection approximating true width.
“The intersection of sulphide mineralisation in all three initial holes at Havilah, including thick zones of copper and zinc sulphide mineralisation in HVD003, indicates we’re on top of a large porphyry-sulphide system with similar characteristics to other major copper-gold discoveries in the Lachlan Fold Belt such as Cadia-Ridgeway and the recent Boda-Kaiser discovery," CEO, Jon Dugdale, said.
“We look forward to completing the remainder of our diamond drilling programme and receiving the laboratory results from the holes completed, which will be released as soon as they come to hand and are compiled.”
Hand-held pXRF readings from the most intensely mineralised zone in HVD003 from 85m to 113m (28m) ranged up to 18.5% Cu and 34.8% Zn and averaged 0.5% Cu and 0.7% Zn. High tungsten (up to 1.38%) and cobalt (up to 798ppm) values were also recorded in this zone.
A second zone of mineralisation from 152m to 166m produced pXRF zinc values ranging from less than detection to 4.6% Zn (averaging 0.3% Zn) with lower grade copper values.
