Golden Deeps (ASX: GED) continues to grow its promising Havilah copper project in the prolific Lachlan Fold Belt of NSW.
The company has revealed in its latest drilling results that it has intersected a 92-metre-thick zone of copper mineralisation in HVD004, the fourth hole of the current diamond drilling program at Havilah.
The hole, which tested the Hazelbrook copper-zinc soil and rock chip anomaly, is located 200m to the north-east of the previously reported HVD003 hole that intersected an 80m sulphide mineralised zone from 85m.
Long anomaly
Chief executive officer Jon Dugdale said the mineralisation intersected by HVD003 and HVD004 is associated with a north-east-trending surface soil and rock chip copper-zinc anomaly defined by detailed soil and rock chip sampling results of more than 1% copper over at least 800m of strike length.
“The widespread mineralisation at Havilah indicates we’re on top of a large porphyry-sulphide system with similar geological characteristics to major deposits in the Lachlan Fold Belt, such as Cadia-Ridgeway,” Mr Dugdale said.
“Subject to laboratory assay results – including for gold and silver – and further soil sampling, we look forward to launching a new drilling program to test this exciting discovery of widespread, copper-bearing sulphide mineralisation.”
Growing strike
Golden Deeps believes the previous, wide-spaced soil sampling results of up to 3,460 parts per million copper to the north-east of the detailed sampling zone indicate that the Hazelbrook anomaly extends for over 1km of strike length, open to the north-east and south-west.
The company is currently undertaking a further soil sampling program over a 25m-by-25m area to define the extensions to the Hazelbrook anomaly and provide definition of targets for further drilling.
An in-fill soil sampling campaign is also being carried out over the extensive Milfor copper anomaly, which occurs over a 1km by 1km area and includes soil values of up to 1,150ppm copper.
pXRF test work
The sampling at Hazelbrook and Milfor will be analysed using portable X-ray fluorescence (pXRF) to produce immediate results that will allow for the definition of further drilling targets in both of these highly mineralised areas.
Golden Deeps says work to date has identified an area of extensive surface copper mineralisation.
The company believes the strong sub-surface induced polarisation anomalies detected represent a major porphyry/volcanic-hosted copper-zinc-gold target zone at Havilah.
