Applied modern day technology – this is the key to unlocking the potential at Broken Hill.
Perilya manages 1,042 square kilometres of prospective terrain around Broken Hill, which includes exploration licences over the historic Little Broken Hill and Pinnacles area, and mine leases incorporating the Southern Operations, North Mine and Potosi line.
Exploration activities continue at Little Broken Hill, the Pinnacles and Stirling Vale where significant high-grade intercepts identified indicate that these assets could play a key role in the future of the Broken Hill operations.
The Broken Hill ore body is the largest base metal ore body in the world, however controls on mineralization are poorly understood, despite decades of research.
geology and testing
The Broken Hill mine is situated in high-grade metamorphic rocks of the Early Proterozoic Willyama Supergroup in the Broken Hill Block of western New South Wales.
The ore deposit, consisting of six or more distinct lode horizons, is generally stratabound, with intense structural modification along shears and related folds causing complex ore geometries and upgrading of mineralisation.
The scale and complexity of the deposit makes it an attractive exploration play with considerable potential for structural repetitions of the various ore lenses. Perilya is committed to extending the mine life through replacing ore mined and increasing the reserve base.
An understanding of the geological controls on ore formation is crucial for targeting new mineralisation and extensions to the known ore bodies, both in the near-mine environment, and on a regional scale.
looking forward
The company is expanding its operations at Broken Hill mine through the development of an exploration decline at Potosi, redeveloping the North Mine via a development decline, conducting an open pit feasibility study into the Flying Doctor deposit and conducting exploration within a 10 kilometre radius of the concentrator.
