facilities

Slow, long-term movement where the stakes are high, the timescales run to years, and the real signal hides in the noise. The hard part isn't collecting the data — it's reading it.

How we prove it

Satellite InSAR and monthly mapping — read as one record.

For tailings, DTG combines wide-area satellite deformation with recurring water-body mapping into one continuous, governed, long-term record of how the facility is behaving.

Satellite InSARWide-area ground deformation across the whole facility — through our partnership with Catalyst Earth.

Monthly water mappingThe pond and water extent mapped every month — a consistent, comparable long-term record.

Machine-learning readAnalytics that pull real, slow deformation out of noisy, real-world data.

InSAR data in partnership with Catalyst Earth

A tailings facility doesn’t move like a pit slope. The movement that matters is tiny and slow — and on a vegetated embankment it’s easily swamped by wind, weather and atmospheric noise.

What's different here

The challenge isn't speed — it's confidence over years. Pulling a reliable long-term signal out of noisy data is what turns a monitoring record into a decision.

What DTG actually does

We turn noise into a signal you can act on.

On a real embankment, the movement that matters is buried under environmental noise. DTG's difference is the analytics that surface the clean, slow-deformation trend — so it's caught early, not lost.

This is DTG’s analytics capability at work. The machine-learning methods behind it — anomaly detection, trend extraction, and more — are the core of what we do, and we’ve published them on real long-term tailings monitoring.

How we monitor it

Wide-area coverage, read against the ground.

TSF monitoring combines satellite-scale deformation with ground truth — so slow movement is caught early and read in context.

DTG's independence is the point: on your facility, what we recommend is driven by your data, not by any product. We integrate whatever sources are available — and because the value is in how we read them, new sources simply add to the record.

Wide-area

Ground deformation across the whole facility, including areas without instruments — satellite InSAR, via Catalyst Earth

Recurring

Pond and water extent, mapped monthly — a key TSF risk indicator over time

Sub-surface

Pore pressure and phreatic surface — piezometers

Point

Precise movement at embankment points — GNSS & prisms

Where DTG's role ends

We monitor and interpret. The accountable team decides.

Being clear about the boundary is part of being trustworthy. DTG provides independent monitoring, deformation interpretation and a defensible long-term record — strengthening oversight of the facility, not replacing the people accountable for it.

We provide monitoring, InSAR, mapping, and deformation interpretation.

We work within recognised tailings governance good practice.

Accountability for the facility remains with the responsible engineers.
