Havilah Resources Ltd’s (ASX:HAV) (FRA:FWL) recent drilling at its Kalkaroo copper-gold-cobalt deposit in South Australia has returned consistent widths and high grades of copper-gold sulphide mineralisation.
Two infill reverse circulation (RC) drill transects were completed along strike of the proposed West Kalkaroo gold open pit to establish continuity of the mineralisation between the existing 100 metre spaced drill sections that were used to define the Kalkaroo JORC mineral resource.
Results include:
- 32 metres of 1.69% copper and 0.78 g/t gold from 136-168 metres;
- 57 metres of 1.24% copper and 0.89 g/t gold; and
- 54 metres of 1.20% copper and 0.75 g/t gold, including 25 metres of 1.96% copper and 0.91 g/t gold.
The results will be used for future mine planning studies and the gold intersections will be followed up in due course with more closely spaced, shallow aircore drilling prior to any future eastward extensions of the West Kalkaroo gold open pit.
“Consistently economic copper and gold grades”
The company’s priority focus during recent months has been on advancing several key tasks that are required to commence the West Kalkaroo open pit gold mine and also carrying out additional infill drilling to gain greater confidence in the mineral resource.
Havilah technical director Dr Chris Giles said: “Infill resource confirmation drilling continues to demonstrate good continuity of sulphide mineralisation at consistently economic copper and gold grades as is characteristic of the Main Kalkaroo orebody.
“This is positive for the longer-term sulphide development potential.
“In the meantime we continue to engage with the DEM concerning permitting approvals as well as potential mining contractors and financiers in relation to the West Kalkaroo gold deposit.
“Our priority objective remains advancing the West Kalkaroo gold open pit towards development during 2022, subject to a final investment decision by the Havilah Board, obtaining financing and final South Australian government approvals.”

Looking forwards
The company is continuing discussions with potential mining contractors and project financiers, and is in the process of addressing initial feedback from the Department for Energy and Mining (DEM) on the Kalkaroo Program for Environment Protection and Rehabilitation (PEPR).
Drilling has now shifted to infill resource confirmation drilling at East Kalkaroo.
Subject to the timely completion of the various outstanding pre-development tasks, the Kalkaroo Project remains on track to commence during early 2022.
