HAVILAH Resources says 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, resulting in a measured resource of 62 million tonnes of 0.55% copper and 0.44 g/t gold.
Chairman, Bob Johnson says 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 says 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 above resource estimate relies on results from a total of 353 drillholes, including 234 RC and 117 diamond tailed core holes and 2 AC holes. The database used for the resource calculation includes a total of more than 31,000 assayed samples and over 11,000 density measurements from core samples.
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.
