    Atlas Iron’s Sanjiv Ridge Stage 2: design and earthworks notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Atlas Iron, owned by Hancock Prospecting, has approved Stage 2 of its Sanjiv Ridge iron ore project in Western Australia’s Pilbara, expanding production from the existing Sanjiv Ridge and nearby Miralga Creek deposits. The development will rely on conventional open-pit mining, haul trucks and on-site crushing before road haulage to port, leveraging existing Pilbara logistics rather than new rail. For geotechnical and civil contractors, the decision signals upcoming work in pit wall design, haul road construction and waste dump earthworks in hard banded iron formation terrain.

    Technical Brief

    • Stage 2 approval enables further cutbacks and waste stripping in existing Sanjiv Ridge pits.
    • Atlas Iron will integrate Stage 2 ore with Miralga Creek feed through shared crushing infrastructure.
    • Haulage will extend current road-train routes, implying incremental upgrades to Pilbara private haul roads.
    • Additional ROM pads and stockpile areas are expected to be developed on constrained ridge topography.
    • Waste landforms will likely expand on hard BIF foundations, requiring controlled lift placement and drainage.
    • Scheduling of Stage 2 alongside Miralga Creek operations will drive tighter drill-and-blast and fleet sequencing.
    • For similar Pilbara satellite deposits, the model reinforces road-based hub-and-spoke logistics over new rail.

    Our Take

    Within our 97 iron ore‑tagged pieces, Western Australia’s Pilbara dominates coverage, signalling that Atlas Iron’s Sanjiv Ridge Stage 2 is competing for haulage, port slots and contractor capacity in an already congested iron ore province.

    Hancock Prospecting’s backing places Sanjiv Ridge alongside other privately financed Pilbara iron ore operations in our database, which typically move from approval to first ore faster than listed peers because they are less constrained by public-market capex cycles.

    The progression to Stage 2 at Sanjiv Ridge, following work at Miralga Creek, suggests Atlas Iron is focusing on shorter-lead, satellite-style deposits rather than mega-hub developments, a pattern that in our coverage often aligns with flexible mine planning and opportunistic responses to iron ore price swings.

    Anglo Asian–Worley Xarxar, Garadag studies: capex and layout insights for mine planners

    Anglo Asian Mining has appointed Worley Europe Limited to deliver full feasibility studies for its Xarxar and Garadag copper-gold projects in Azerbaijan, moving both assets towards potential development decisions. Worley, part of Australia-headquartered Worley Group, will apply its global open-pit and processing-plant design capability to define mine layouts, metallurgical flowsheets and infrastructure requirements. The work is expected to firm up capital and operating cost estimates and clarify options for staged development and shared infrastructure across the two deposits.

    Veracio–Bureau Veritas Latin America rollout: drill-to-model gains for mine teams

    Veracio and Bureau Veritas have signed an MoU to roll out Veracio’s advanced geological scanning technologies across Chile, Peru, Argentina and Brazil, with scope to extend into other Latin American markets. The collaboration is expected to pair Veracio’s digital core scanning and downhole sensing tools with Bureau Veritas’ regional laboratory and inspection network to speed up geological data acquisition and QA/QC. For miners, this could tighten drill-to-model cycles, improve orebody characterisation and standardise high-resolution geoscientific datasets across multiple operations.

    Sandvik–Diemme Filtration deal: integrated dewatering flowsheets for mine designers

    Sandvik has agreed to acquire Italy-based Diemme Filtration, adding high-performance mining filter presses and dewatering systems as a new Filtration division within its Rock Processing business area. Diemme’s portfolio includes large automated filter presses for tailings and concentrate dewatering, targeting dry-stack tailings and reduced process water consumption in large concentrators. The move gives Sandvik an in-house solution for integrating crushing, screening and filtration flowsheets, with potential implications for tailings storage design and water balance in brownfield and greenfield plants.
