From 3 halos to 6 industrial anomalies: the El Cóndor 3D model

How remote imaging plus NMR turned a lightly explored gold block into a prioritised drilling plan — with nineteen mineralised bodies reconstructed in volumetric 3D.

Starting from the surface

The block sat in a lightly explored metallogenic belt. Early surface work had outlined three broad anomaly halos — enough to be interesting, not enough to drill against with confidence. The question was how to move from surface hints to defined, drillable targets without a long, invasive campaign.

Two phases, four months

Phase I and II mapping refined those three halos into six georeferenced industrial anomalies. NMR characterisation then resolved the geometry at depth, reconstructing nineteen mineralised bodies across nine depth sections — from 45 metres down to just over 5,000 metres.

Why volumetric 3D matters

A flat anomaly map tells you where to look; a 3D model tells you how to drill. Seeing the bodies in volume — their depth, extent and relationship to one another — turns scattered targets into a single, coherent geological picture and a prioritised drilling plan.

Informed drilling, not blind drilling.
