Austral's $80.7m Hammer Bid Sets Up Copper Takeover Fight

Austral Resources Australia (ASX: AR1) has submitted a binding proposal to acquire Hammer Metals (ASX: HMX) through a scheme of arrangement, a move Hammer's board has unanimously deemed superior to its existing transaction with Larvotto Resources (ASX: LRV).

The offer values Hammer at roughly $80.7 million, or $0.087 per share. That figure breaks down into 1.2903 Austral shares per Hammer share, intended to represent about $0.080, plus a further $0.007 tied to a demerged vehicle that would hold Hammer's Western Australian gold assets.

Hammer shareholders would end up with approximately 31.1% of the enlarged group. Existing Austral shareholders are expected to hold the remaining 68.9%.

The deal is built around geography. Austral operates the Rocklands copper flotation plant, 17km west of Cloncurry in Queensland, which is being recommissioned for a targeted mid-2027 restart. Hammer's Kalman copper-gold-molybdenum-rhenium deposit sits about 60km away by existing roads, with a stated 39.2 million tonne mineral resource grading 1.1% copper equivalent. Austral sees that ore as a long-term feed source for Rocklands, avoiding the cost of a standalone development or third-party tolling arrangement.

Beyond Kalman, the combination would fold in Hammer's roughly 3,600 sq km of Queensland tenure across the Mount Isa region, including the Overlander, Lakeview, Elaine, and Jubilee deposits.

Austral chair David Newling framed the deal as a natural pairing. "The transaction brings together two highly complementary Queensland copper businesses and provides a pathway to combine Hammer's high-quality resource base with Austral's existing processing infrastructure, operational capability and strong balance sheet," he said. "We believe the combined group will be well positioned to accelerate development opportunities across the broader region and deliver long-term value for shareholders as we continue to build out Australia's next mid-tier copper powerhouse."

The proposed structure carries a quirk. Each Hammer shareholder would receive 1.2903 Austral shares per share and retain ownership of the Bronzewing South, Orelia North, and Mt Sefton gold assets through a proposed SpinCo demerger. That split explains the $0.007 allocation in the headline valuation.

Austral has also offered Hammer a bridging facility of up to $6 million to cover operations during the scheme period, repay the outstanding Larvotto loan, and fund any break fee payable under the existing scheme implementation deed.

The offer is not subject to financing or due diligence conditions. Implementation still requires Hammer shareholder and court approvals, a favourable independent expert conclusion, regulatory clearances, and completion of the SpinCo demerger.

Larvotto now holds a five-business-day matching right, which expires at 11.59pm AWST on 10 August. Until that deadline, Hammer cannot enter a binding agreement with Austral. There is currently no binding agreement between the two, and completion is not assured despite the board's superior-proposal finding.

If the transaction clears the hurdles, Austral's indicative timetable targets a scheme booklet and first court hearing in September, shareholder and second court hearings during October or November, and implementation after that. A merged group could carry a market capitalisation above $250 million.

The fight comes at a time when Queensland copper assets are drawing renewed attention. For a sector context, see our commodities analysis.

The key date is the 10 August matching-right deadline. Larvotto can still counter, and Hammer's board would then have to weigh a revised proposal against the Austral offer it has already called superior.
