• Surveys at the Icebreaker prospect outlined an IP chargeability feature of about 1.5 square kilometres, reaching 60 millivolts.
  • An initial 3,000 metre diamond and Reverse Circulation Drilling programme is planned to start in October 2026, with first assays expected in late November 2026.
  • The 2026 mineral resource estimate is 5.2 million tonnes at 0.7 grams per tonne gold for 118,496 ounces; the anomalies are not part of it.

Broken Hill Gold Ltd (ASX:BH6) has reported results from new Geophysical surveys at its 100 per cent owned White Dam Gold-Copper Project, in the Curnamona Province of South Australia, about 80 kilometres west of Broken Hill. The company said the surveys identified large induced polarisation (IP) and magnetic anomalies at the Icebreaker prospect, and it plans an initial 3,000 metre diamond and reverse circulation drilling programme starting in October 2026.

What the surveys found

The work was carried out by Planetary Geophysics Pty Ltd, engaged in early September 2026. It comprised nine pole-dipole IP transects at 200 metre spacing, totalling 50 line-kilometres over the Icebreaker and Rolling areas, plus 319 line-kilometres of ground magnetics on north-south lines at 40 metre spacing.

The IP survey outlined a chargeability feature of about 1.5 square kilometres. It includes a deeper, high-intensity eastern anomaly reaching 60 millivolts, about six times the 10 millivolt background, located north of the eastern Margin of the Hannaford open pit. A shallower north-western anomaly of up to 40 millivolts lies between Rolling and Icebreaker and coincides with previously drilled sulphide mineralisation. The magnetics show a high-intensity feature of about one square kilometre at Icebreaker and Rolling, coincident with the IP anomaly and interpreted by the company as iron oxide alteration. A second IP anomaly about one kilometre south-west of Icebreaker has an unknown source and has not been drilled.

Drilling plans

The company noted that historic reverse circulation holes average about 50 metres vertical depth, with only a limited number deeper than 100 metres. The planned programme includes diamond holes to about 400 metres to test the north-western and main eastern IP anomalies, along with tests along strike and at depth and of the south-west anomaly. First assays are expected in late November 2026. Resource drilling is also continuing at the Icebreaker oxide zone and Hannaford, with testing at Rolling and Pixie.

Resources and context

The announcement restates the company's 2026 mineral resource estimate under the JORC Code 2012: 5.2 million tonnes at 0.7 grams per tonne gold for 118,496 ounces. That comprises 2,333,011 tonnes at 0.6 g/t (43,500 ounces) Indicated and 2,867,200 tonnes at 0.8 g/t (74,996 ounces) Inferred. By deposit, Vertigo holds 54,795 ounces, Hannaford 43,300 ounces and Icebreaker 20,400 ounces. The resource is gold only; the geophysical anomalies are not part of it.

The company says the project area has produced about 180,000 ounces of gold historically, including about 120,000 ounces from Hannaford between 2010 and 2018. It also lists regional iron oxide copper-gold (IOCG) deposits for comparison, including Kalkaroo (1.1 million tonnes of copper and 3.1 million ounces of gold) about 40 kilometres north. These are other companies' deposits and do not indicate what White Dam may contain.

Other programmes and milestones

Broken Hill Gold said an IP survey over Vertigo is in progress, with IP and magnetics planned at Mary Mine, Green and Gold and Wilkins in October and November 2026. Exploration at the Wadnaminga Mining leases is due to begin in November 2026, with drilling in early 2027. Mining studies and a final Investment decision on a Vertigo restart are targeted for the first quarter of 2027.
