HAVILAH Resources said its geologists have generated a detailed geological model of the Kalkaroo deposit, South Australia.
This geological model has formed the basis for an updated resource estimation, completed by a specialist geologist using Vulcan 3D software.
This resulted in a measured resource of 62 million tonnes of 0.55% copper and 0.44 g/t gold.
Havilah Chairman Bob Johnson said he was re-assured that the 62 million tonne copper and gold resource at Kalkaroo had been defined by several generations of drilling, which had shown the mineralisation to be remarkably consistent and predictable.
He said that Kalkaroo ranks as one of the largest undeveloped copper-gold deposits in Australia.
Havilah Resources says that its immediate objective is to develop Kalkaroo as South Australia’s next large copper mine.
The feasibility study drilling focussed on defining only that part of the resource that was considered directly amenable to open pit mining.
The potential to define further resources outside of the present measured resource is considered high based on existing, widely spaced mineralised drill intersections down dip and along strike.
