Impact Minerals Limited (ASX: IPT) Broken Hill Reborn
Impact Minerals Limited (ASX: IPT)
• Exploration at Impact’s 100% owned Broken Hill project in NSW to be resumed in light of increased metal prices, new in-house exploration concepts and renewed exploration interest and corporate activity in the region.
• Impact’s tenements are prospective for three different styles of mineralisation:
Early-stage large sedimentary or magmatic copper deposits, a concept developed during Impact’s participation in the inaugural BHP Xplor program. High-grade magmatic nickel-copper-PGM sulphides associated with late stage (820 Ma) ultramafic to mafic intrusions with key prospects at Platinum Springs, Red Hill and Rockwell-Little Broken Hill; and Broken Hill-style silver-lead-zinc mineralisation, including the Dora East prospect.
• A progressive review of all previous exploration is underway, with results for Platinum Springs reported here.
• A key diamond drill hole intercept was returned from one of Impact’s first drill holes (PSD02) of 0.6 metres at 7.6% copper, 7.4% nickel, 25.6 g/t palladium, 11.5 g/t platinum, 1.4 g/t gold, 44.3 g/t silver, 1.3 g/t rhodium, 1.7 g/t iridium, 2.0 g/t osmium and 0.8 g/t ruthenium from 57.4 metres down hole.
• In 2020, Impact identified a proprietary multi-metal ratio measurable with a hand-held XRF instrument that reliably correlated with PGE grades, allowing real-time vectoring toward high-grade zones during drilling.
• Using this technique, Impact defined the first consistent zones of higher-grade nickel–copper–PGE mineralisation in four decades of exploration and showed that it occurs in ribbon-like channels at the base of the host intrusion, similar to those that host the world-class Kambalda nickel deposits.
• Three new channels were identified across the Plat Central and Plat East prospects which included drill intercepts of . 1 metre at, 10.9 g/t palladium, 7.3 g/t platinum, 0.9 g/t rhodium, 1.3 g/t osmium, 1.4 g/t iridium and 0.6 g/t ruthenium and 0.1 g/t gold, 3.3 % nickel, 1% copper and 23 g/t silver from 62 metres; and
7 metres at 3.8 g/t 7PGE, 0.6% copper, 0.5% nickel and 9.4 g/t silver from 53 metres including 1 metre at 3.6 g/t palladium, 1.8 g/t platinum, 0.1 g/t rhodium, 0.2 g/t iridium, 0.2 g/t osmium and 0.1 g/t ruthenium and 0.3 g/t gold, 1.2% copper, 0.8% nickel and 19 g/t silver.
• All three channels are open along trend and at depth and demonstrate the potential for the discovery of multiple channels along the 9 km length of the host intrusion called the Moorkai Trend, which is host to many high-grade rock chip results that have never been drilled.
• Follow up work programs will include detailed ground EM surveys to help identify targets for further drilling
Impact Minerals Limited (ASX: IPT) is pleased to announce that it is resuming exploration at its 100%- owned Broken Hill Project in New South Wales which covers 1,770 sq km of ground surrounding one of the world’s most significant mines, the Broken Hill silver-lead-zinc deposit, containing over 500 million tonnes of massive sulphide mineralisation.
The restart is driven by sharp price increases in gold, silver, platinum, palladium, and copper, along with widespread high-grade occurrences of these metals across Impact’s tenements. It is also motivated by intellectual property generated during Impact’s participation in the inaugural BHP Xplor program in 2023 for the discovery of large copper deposits and now brought to the fore.
Additionally, the Broken Hill region is witnessing renewed exploration interest. Broken Hill Mines (ASX: BHM, formerly Coolabah Metals Limited) recently acquired the privately owned Rasp Mine in Broken Hill and the nearby Pinnacles deposit. Notably, high-grade drill results have since been returned from both deposits, which are likely to significantly extend the operational life of the Broken Hill mine, which has operated almost continuously for 142 years since its original discovery in 1883. Also, South32 Limited has entered into a joint venture with a private company that owns a substantial landholding north of the Broken Hill mine.
Impact has steadily built a significant tenement portfolio in the area and is now one of the largest ground-holders in the region, especially to the south of Broken Hill where the company owns 100% of tenements covering 1,770 km² and over 100 kilometres of strike (Figure 1 and ASX Releases January 17, 2023, February 16, 2023 and March 10th 2025).
Impact Minerals’ Managing Director, Dr. Mike Jones, said, “Although we are making important progress on all aspects of our work in the High Purity Alumina field, both at Lake Hope and with our major investment in Alluminous Pty Ltd, there is still unfinished business for Impact at Broken Hill. Given the recent sharp rises in precious metal and copper prices, and the area's revitalisation following the recent acquisition of the famous Rasp Mine by Broken Hill Mines Limited (ASX:BHM), some of our recently raised funds will be allocated to revamping our exploration efforts there. Our previous work identified numerous high-grade prospects for nickel-copper-PGMs and Broken Hill-style silver-lead-zinc mineralisation, both of which still require follow-up. Additionally, we have developed new theories for large copper deposits based on our participation in the inaugural BHP Xplor program in 2023, which, earlier this year, resulted in us acquiring a substantial new ground-holding in the region. We are currently conducting a ground magneto-telluric survey to help identify drill targets for early 2026, and we are eager to see the results.”,
