Decide with evidence.

An introduction to VEXRAD’s Atomic Dielectric Resonance (ADR) technology, surface acquisition, depth-referenced Virtual Boreholes and the role of ADR in better-informed subsurface decisions.

Virtual Boreholes

Surface-acquired electromagnetic measurements. Depth-referenced interpretation. An additional evidence layer before drilling.

WHAT’S INSIDE

From surface measurement to subsurface decision

The brochure provides a concise introduction for geologists, exploration teams, asset owners and technical decision-makers evaluating where ADR could add useful evidence.

1

ADR Technology

How VEXRAD uses surface-deployed coherent pulsed electromagnetic measurements to investigate subsurface response.

2

Survey Workflow

Project scoping, acquisition, quality control, processing, interpretation and integration with existing geological information.

3

Virtual Boreholes

Depth-referenced, log-style interpretations designed to help characterise geological change and candidate target intervals.

4

Applications

How the approach can support critical minerals, geothermal, water and other subsurface investigation programmes.

THE VIRTUAL BOREHOLE

A borehole before the borehole.

A VEXRAD Virtual Borehole is a depth-referenced interpretation constructed from surface ADR measurements at a selected location.

The brochure includes a genuine legacy ADR Virtual Borehole example showing the multi-track interpretation process — including rock-type/typecasting information, material-match indicators, energy response, dielectric response, returned-frequency/E-ADR information and final interpreted lithology.

WHERE ADR CAN ADD EVIDENCE

Built around subsurface decisions

Critical Minerals

Interrogate selected targets vertically, investigate geological changes with depth and provide an additional evidence layer for target ranking and drill planning.

Geothermal

Support pre-drill characterisation of lithology, structures and candidate intervals as part of an integrated geothermal exploration workflow.

Water

Investigate subsurface changes and potential water-related intervals to support groundwater exploration and monitoring programmes.

What ADR is not: a Virtual Borehole is not a physical borehole and does not provide core, laboratory assays, reserves, guaranteed permeability, flow rate or drilling success. VEXRAD uses ADR as an additional subsurface evidence layer. Physical drilling and independent ground truth remain the definitive test.
