The GMA Toolkit

Tools built for the questions you're already asking.

Five interactive tools developed in-house by Green Mines Australia, calibrated to Western Australian conditions and aligned to the DEMIRS Guideline for Preparing Mine Closure Plans (Sept 2025). Each is order-of-magnitude — a starting point for planning conversations, not a substitute for site-specific quotation.

01
Cost Lens

What might your rehabilitation cost?

Order-of-magnitude estimator calibrated to Collie, Pilbara, Goldfields and Mid-West conditions. Inputs: area, slope, substrate, topsoil logistics, end land use. Returns a defensible cost range with category breakdown across earthworks, topsoil, amelioration, revegetation and five-year monitoring.

5 inputs ~2 min For planners & estimators

02
Closure Self-Assessment

How submission-ready is your closure plan?

A ten-question self-assessment mapped to the DEMIRS Mine Closure Plan Guideline. Covers stakeholder engagement, completion criteria, risk, cost estimation, progressive rehabilitation and financial provisioning. Returns a weighted readiness score with a category-by-category breakdown.

10 questions ~4 min For closure managers

03
Erosion Control

Pick the right hydromulch system.

Matches batter geometry and substrate to the correct DuraVeg product, application rate and surface preparation. Returns timing windows by region and the applicable cyclone-season operational rules. Drawn from GMA's field-proven methodology (procedure GMA-REH-PROC-002).

3 inputs ~1 min For site engineers

04
Seasonal Planning

When can you safely hydromulch on the Pilbara?

Twelve-month application planner for Flexterra HP-FGM and related products on the Pilbara coast. Each month is calibrated against tropical cyclone climatology and seasonal rainfall, with operational rules for cyclone watches and post-system resumption.

Verified Outcomes

From disturbance to thriving landscape.

Drag through projects from the GMA portfolio — Collie Basin batter rehabilitation, Pilbara haul-road erosion control, Goldfields waste landform revegetation — to see measurable outcomes against agreed completion criteria. Method and verified outcome documented for each.

About these tools.  Each tool is built in-house by Green Mines Australia and reflects current Western Australian regulatory expectations, field-tested methodologies and project experience. All outputs are order-of-magnitude and intended to support early-stage planning, feasibility and conversation — not to substitute for site-specific assessment, quotation or competent-person sign-off.
