Exploration & Current Projects
Kalkaroo is one of the larger undeveloped open pit copper deposit in Australia on a CuEq Ore Reserve basis.
It contains 1.1 million tonnes of copper, 3.1 million ounces of gold and 23,200 tonnes of cobalt in Measured, Indicated and Inferred JORC Mineral Resources.
BHP (previously OZ Minerals) has recently completed a comprehensive Study Program on the Kalkaroo deposit that found no fatal flaws. The resulting financial model confirms a robust long-life project with favourable development prospects.
The Mutooroo is a lode-style massive sulphide copper-cobalt deposit located about 60 km southwest of Broken Hill.
It contains a Measured, Indicated and Inferred JORC Resource of 13.1 million tonnes of 1.53% copper, 0.16% cobalt and 0.20 g/t gold for a total contained 195,000 tonnes of copper, 20,200 tonnes of cobalt and 82,100 ounces of gold.
The Grants iron ore project lies 8 km south of the Barrier Highway and the Transcontinental Railway, and one hour drive southwest of Broken Hill.
A substantial magnetite-hematite iron ore deposit was defined during 2012 as the result of drilling laterite capped hills following the discovery of subtle iron ore outcrop by Havilah geologists.
The Maldorky iron ore project lies approximately 26 km south of the Barrier Highway and the Transcontinental Railway, 300km east of Port Pirie and one hour drive southwest of Broken Hill.
It was discovered by Havilah geologists during 2010 as the result of drilling a prominent magnetic anomaly associated with poorly outcropping Braemar Iron Formation.
The Prospect Hill tin project, located on the northern margins of the Flinders Ranges, is South Australia’s largest known tin resource.
Previous shallow drilling by Marathon Petroleum during the early 1980’s established an inferred resource of 172,000 tonnes of 1.15% tin to a vertical depth of 50 metres and over a strike length of 280 metres on the South Ridge prospect.
Havilah controls more than 16,000 km² of mineral tenements in the Curnamona Province in northeastern South Australia, a highly mineralised region is host to the largest lead-zinc deposit in the world at Broken Hill.
Havilah’s cost-effective exploration over the last two decades has been very successful in delineating a JORC Mineral Resource metal inventory of 1.3 million tonnes of copper, 3.2 million ounces of gold, 43,400 tonnes of cobalt and 451 million tonnes of iron ore, plus appreciable molybdenum, tin and uranium.
The Curnamona Province Strategic Alliance regional exploration drilling funded by Oz Minerals during 2022-2023 targeted a province wide copper-gold exploration play. It highlighted four multi-commodity prospects within 15 km of Kalkaroo with the scale to potentially generate new Kalkaroo size discoveries.
Rare Earth Elements (REE)
Rare Earth Elements (REE) are widely associated with copper-gold mineralisation in the Curnamona Province.
Recovery of a by-product REE mineral concentrate can potentially provide an additional revenue stream for Havilah's copper-gold mining projects.
