What you buy

One surface location. Thousands of metres of subsurface intelligence.

A Virtual Borehole turns surface-acquired ADR measurements into a depth-resolved interpretation designed to help identify and rank what deserves further investigation.

01

Surface location

Choose the target station.
02

ADR acquisition

Collect subsurface responses from the surface.
03

VEXRAD processing

Process signals and derive interpretable parameters.
04

Virtual Borehole

Create a depth-resolved subsurface profile.
05

Ranked targets

Identify intervals for further investigation.
06

Drill decision

Use the evidence to inform the next step.
What you receive

A depth-resolved picture of your target.

This is real VEXRAD project output — not a conceptual illustration. The Virtual Borehole combines depth, interpreted ADR lithology and target confidence into a vertical view designed around the questions that matter to the project.

Depth model

A depth-resolved interpretation of changing subsurface responses.

Target intervals

Intervals that warrant additional investigation or prioritisation.

Confidence

Interpretation presented with uncertainty rather than certainty.

Evidence classification

Validated · Grounded · Candidate · Known Null.

Lithology & boundaries

Where data quality, calibration and evidence support geological interpretation.

Decision-ready report

Results, limitations, evidence strength and recommended next steps.

From Virtual Borehole to real borehole

The important test is what happens when you drill.

VEXRAD compares Virtual Borehole predictions with independent ground truth wherever suitable evidence is available.

Scale the intelligence

One Virtual Borehole investigates depth. Multiple Virtual Boreholes investigate the target.

A network of surface stations can help explore lateral continuity, correlate interpreted horizons and rank locations for further investigation.

Clear boundaries

What a Virtual Borehole does — and does not — claim.

ADR can help identify

  • Lithology and formation boundaries
  • Structures and subsurface changes
  • Target intervals
  • Reservoir indicators
  • Subsurface anomalies
  • Priorities for further investigation

ADR does not guarantee

  • Assay grade
  • Resource or reserve estimates
  • Permeability
  • Flow rate
  • Commercial discovery
  • Drilling success
A Virtual Borehole informs the drill decision. It does not replace the drill.
Built for the decision before the drill

Different targets. The same question: where should we investigate next?

Geothermal

Where is the reservoir?
Lithology · reservoir intervals · structures · thermal indicators.

Critical minerals

Where should we drill first?
Host geology · structures · mineralisation indicators · target depth.

Water

Where should we investigate?
Aquifer indicators · lithology · structures · depth.

Your target. Your next drill decision.

Find out whether ADR fits your target.

Before committing to a survey, VEXRAD can assess the geology, target, available data and what a Virtual Borehole programme could realistically help resolve.
