Reading a licence area with data that was already flown over it

Most exploration licences in the region sit on more geophysical and satellite coverage than anybody has looked at carefully. Fusing what exists is usually cheaper than acquiring more.

In short

  • Regional airborne surveys often cover ground the licence holder has never processed.
  • Fusion of several weak signals beats one strong one, and costs nothing to acquire.
  • Ranked targets with stated confidence are more useful than a map of anomalies.
  • The output should say what would change the ranking, not just what the ranking is.

An exploration manager has a licence, a budget and a question: where should the next drill programme go. The usual answer is to acquire more data. Often there is a cheaper step first.

What is already there

Regional airborne magnetic and radiometric surveys, government geological mapping, historical geochemical sampling, and two decades of free optical and radar satellite imagery. Individually none of it resolves a target. Together, processed consistently and co-registered properly, it narrows the ground considerably.

Fusion, not stacking

The work is not simply overlaying layers. It is deciding what each dataset is evidence for, at what scale, with what reliability, and combining them in a way that reflects that. A weak magnetic response coinciding with an alteration signature in the imagery and an elevated pathfinder element in old stream sediment is a stronger case than any one of the three.

Ranked, with confidence

The deliverable is not a map of anomalies. It is a ranked list of targets, each with the evidence behind it, a stated confidence, and the single piece of information that would most change its position. That last column is what makes the output actionable: it tells the manager what the next, cheapest step is for each target rather than implying the analysis is finished.

When new acquisition is the right call

Sometimes it is, and the fusion work tells you where to fly rather than flying everything. A targeted survey over three ranked areas costs a fraction of blanket coverage and answers a specific question.
