Geoscience Australia Green Iron StoryMap: siting insights for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Geoscience Australia has released the Green Iron StoryMap, an interactive tool within the Digital Atlas of Australia that layers iron ore deposits, renewable energy zones, existing rail and port corridors, and water resources to map green iron potential. Users can interrogate spatial data on proximity of high‑grade ore bodies to wind and solar resources, transmission lines and gas pipelines, helping screen locations for hydrogen‑based direct reduction or electrified pelletising. For miners and infrastructure planners, it offers a first‑pass, national‑scale view of where integrated green iron hubs could be technically viable.
Technical Brief
- Green Iron StoryMap is delivered as a web-based GIS interface within the national Digital Atlas.
- Tool aggregates Geoscience Australia’s national geoscience datasets with spatial infrastructure and energy layers in one environment.
- Users can toggle multiple thematic layers to visualise co-location of resources, infrastructure and environmental constraints.
- Query functions allow location-specific interrogation rather than relying on static PDF maps or regional reports.
- National coverage enables consistent first-pass screening across all Australian jurisdictions using a single data standard.
- Platform design targets early-stage project scoping, before detailed site investigations or bespoke geospatial studies.
- Integration into the Digital Atlas means updates can track new infrastructure corridors and resource mapping campaigns.
- Similar StoryMap-based workflows could be adapted for other value chains, e.g. critical minerals processing hubs.
Our Take
Geoscience Australia’s Green Iron StoryMap sits alongside its recent continental‑scale mapping work on the Delamerian magmatic arc and high‑resolution gravity surveys in Queensland, signalling that iron ore decarbonisation is being integrated into the same national geoscience framework previously focused on copper, gold and critical minerals.
Within our 34 Software stories, most tools have targeted critical minerals and energy resources; a dedicated iron ore–focused product suggests policymakers now see digital spatial tools as relevant not just for discovery but for planning lower‑emission value chains in Australia’s largest bulk commodity.
Because the Green Iron StoryMap is delivered through the Digital Atlas of Australia, iron ore proponents can technically overlay it with other federal datasets (infrastructure, land use, environmental layers), which is likely to streamline early‑stage screening for green hydrogen, renewable power and logistics options tied to future iron projects.
