    Larvotto buys Hammer Metals: Mt Isa copper portfolio and project lens for engineers

    Larvotto buys Hammer Metals: Mt Isa copper portfolio and project lens for engineers

    First reported on MINING.com

    30 Second Briefing

    Larvotto Resources is acquiring 100% of Hammer Metals in an all‑share deal valuing Hammer at about A$54 million, adding 3,600 km² of Mt Isa tenure anchored by the Kalman copper project and satellite deposits Overlander, Jubilee and Lakeview with a combined 530,000 tonnes copper‑equivalent JORC resource. The enlarged portfolio will sit alongside Larvotto’s existing 900 km² Mt Isa copper ground and the option over the historic Blockade mine, with drilling and development studies to be accelerated. Funding support comes from a A$15 million Glencore equity investment at roughly A$1.53 per share plus expected cash flow from the Hillgrove gold‑antimony mine, due online in August.

    Technical Brief

    • Share exchange ratio fixed at 1 new Larvotto share for every 22 Hammer shares.
    • Implied Hammer consideration of A$0.06 per share reflects an 18% premium to prior close.
    • Transaction values Hammer’s equity at approximately A$54 million (A$37.8 million equivalent).
    • Larvotto’s share price dropped 15% to A$1.12 on announcement, signalling market concern over dilution.
    • Post-fall Larvotto market capitalisation sits around A$581.3 million, versus Hammer at A$45.5 million.
    • Glencore to invest A$15 million via equity at about A$1.53 per share, ~15% premium.
    • Seven‑year gold concentrate offtake with Glencore underpins Hillgrove cash flow assumptions for funding.
    • Hillgrove gold‑antimony project in New South Wales targeted to commence production in August, de‑risking funding.
    • Enlarged Mt Isa copper programme will prioritise accelerated regional drilling and formal development studies.

    Our Take

    Larvotto Resources’ move to acquire Hammer Metals’ copper ground around the Mt Isa district sits alongside its push to restart the Hillgrove antimony–gold mine in New South Wales, signalling a deliberate build-out from a single polymetallic asset into a broader copper–critical minerals portfolio across eastern Australia.

    In our database of 1185 Mining stories, relatively few M&A items combine copper in Queensland with gold‑antimony and tungsten exposure in New South Wales, so the 100% Hammer acquisition positions Larvotto as one of the more diversified mid‑tier critical minerals plays in recent Australian coverage.

    EPC Groupe–Sabodala contract: blasting capacity and slope control insights for engineers

    EPC Groupe, through EPC Mineex Sénégal, has secured a five-year explosives supply and services contract with Endeavour’s Sabodala gold mine in Senegal, valued at about €10 million per year at full run rate. The deal covers bulk explosives and blasting support for one of West Africa’s largest open-pit gold operations, signalling a step-up in local emulsion manufacturing, on-bench services and blast design capability. For mine planners and geotechnical teams, the contract points to stable high-volume blasting capacity, supporting consistent fragmentation and slope performance over the medium term.

    Haultrax HX Coach in FMS: operational coaching and dispatch insights for mine teams

    Haultrax is integrating its on-site operational coaching directly into its Fleet Management System with the launch of HX Coach at IMARC 2026. The module is designed to embed real-time operator guidance and training logic into haulage fleet dispatch, moving beyond traditional FMS reporting towards in-cab behavioural feedback and decision support. For mine operators, this signals a shift from separate coaching programmes to a software-native approach that can systematically influence truck and shovel performance at scale.

    IsaMill at 30: fine grinding efficiency lessons for concentrator engineers

    Glencore Technology is marking 30 years of the IsaMill fine grinding mill, first developed by Mount Isa Mines and NETZSCH to tackle complex, ultra-fine regrind duties in base metal circuits. The horizontal, high-intensity stirred mill has since been deployed in more than 130 installations globally, often replacing ball mills in the sub-20 µm range to cut specific energy consumption and increase throughput. Recent IsaMill developments focus on larger M-series units, improved ceramic media wear performance and integration with modern flotation and coarse particle recovery flowsheets.
