From imagery to a testable question.

Satellite imagery can help examine surface patterns and compare them with mapped features. Geological context and suitable validation are needed to understand what an interpretation means.

HISTORICAL PRESENTATION EXAMPLES

Look for patterns. Keep the interpretation testable.

A February 2026 MinEx consultancy presentation describes applying spectral analysis to satellite imagery and comparing interpreted patterns with mapped features.

The presentation also describes satellite review as a starting point and closer UAV imagery as a possible follow-up when local detail may help. The right data, context and follow-up depend on the question. An interpreted pattern alone does not establish mineralisation or a discovery.

SATELLITE IMAGERY & SPECTRAL ANALYSIS

Comparing spectral patterns with mapped features

MinEx consultancy presentation · February 2026

The presentation compares several spectral analyses of Landsat 8 imagery over a fluorite setting and says interpreted patterns highlighted targets against mapped features. It suggests that higher-quality imagery or UAV data could add detail during follow-up. the source reports no field validation or discovery outcome for this illustration.

ALLUVIAL SETTING

A drainage pattern with more than one history

MinEx consultancy presentation · February 2026

A second presentation example interprets differences between former and present drainage patterns in an alluvial setting and uses spectral imagery to distinguish interpreted river sands from water. The source provides no field check or discovery outcome.

A QUESTION-LED SEQUENCE

Start broad. Add detail when it answers a question.

What imagery, geological context and follow-up are appropriate depends on the project. The sequence below summarizes the approach described in the presentation; it is not a fixed workflow or a claim of current service availability.

Frame the question

Set the exploration question and gather available geological and mapped context.

Review imagery

Examine surface patterns in the available satellite imagery.

Compare context

Consider interpreted patterns alongside known features and project information.

Define a next check

If closer detail would help, consider suitable follow-up imagery and identify evidence that could test the interpretation.

What an image can—and cannot—show.

Imagery may help frame where a closer look could be useful. These historical examples do not by themselves establish mineralisation, a resource, a discovery or a current project mandate.

A project-specific assessment would consider imagery source, acquisition date and resolution, geological control, assumptions, uncertainty and suitable independent or field checks.
