TEM + GPR · Critical-Mineral Exploration

See the ground before you drill.

A portable ground survey system that fuses Transient Electromagnetics and Ground-Penetrating Radar into high-fidelity 3D subsurface digital twins — so you can locate lithium, cobalt and nickel and prioritise drill targets with confidence.

The Problem

Exploration is expensive and blind

Drilling is the single largest cost in early exploration, and most holes miss. Conventional tools struggle with noise and depth resolution, so teams drill on thin evidence — burning budget on dry holes while commodity prices swing.

💸

High cost per discovery

Every blind hole is capital spent with no return. Poor targeting multiplies the cost of every find.

📉

Low resolution, high noise

Standard sensors miss deep, subtle mineral signatures — leaving targets undetected.

⏱️

Slow, uncertain decisions

Raw geophysical data still needs specialist interpretation before a drill plan can be made.

How It Works

Two physics, one digital twin

Transient Electromagnetics resolves conductivity with depth; Ground-Penetrating Radar maps high-resolution near-surface structure. We fuse both and deliver a finished, interpreted 3D model — not raw data.

1

Survey

Roll the cart across the target area to acquire co-located TEM and GPR data.

2

Invert & process

Our algorithms turn raw signals into subsurface conductivity and structure.

3

Digital twin

Receive a 3D subsurface model that fuses depth and near-surface detail.

The Technology

Engineered for deep, quiet sensing

A high-current transmitter with a sharp 15 µs shut-off drives a large plastic-framed transmit loop, while an isolated five-coil receiver array captures the early-time decay that reveals deep mineral signatures standard sensors miss. Proprietary inversion turns it into a map.

Applications

Built for the critical-minerals supply chain

Our physics maps the deposits that matter most to the energy transition.

Nickel & Cobalt

Magmatic sulphide deposits are strongly conductive — classic, high-priority TEM targets detected against resistive host rock.

Lithium

Brine-hosted lithium forms conductive saline aquifers TEM maps exceptionally well; hard-rock pegmatites are resolved with GPR structure.

Rare-Earth & Beyond

Strategic resource mapping, plus adjacent uses — groundwater, regolith thickness, and void/utility detection.

Services
