Mapping What Matters Beneath Cover.

Across mining districts worldwide, including the mature greenstone belt shown as our hero image at PDAC 2026, the next discovery is rarely at surface. It’s buried, structurally controlled, and masked by younger cover.

Full Tensor Gravity (FTG) cuts through that uncertainty.

The image demonstrates how FTG reveals density architecture, intrusive complexes, and structural controls that directly correlate with documented gold mineralisation. The location of the survey is concealed because the data is available to purchase.  

Why FTG? Because Structure Controls Mineralisation.

In this dataset, the contrast is clear:

  • Reds and pinks represent higher-density volcanic, metavolcanic, and metasedimentary sequences.

  • Blue anomalies define lower-density intrusive complexes buried beneath the surface cover.

  • A conglomerate sequence overlies the intrusives, obscuring them from surface mapping.



The key insight: Gold occurrences are aligned along faulted margins of the intrusive bodies. Intrusive complexes drive the system. Structures control the flow. Mineralisation follows the faults.

Reading the Structural Story.

The map reveals

  • Dominant east–west structural trends

  • Cross-cutting northwest-trending fault systems

  • Clear intrusive–host contacts

  • Mineralisation localised along structural intersections and intrusive margins

This is classic greenstone belt geology, intrusive complexes emplaced into volcanic sequences, mineralising fluids focused along structural breaks, and deposits forming at density and rheological contrasts. The result is a gravity response that directly reflects mineral system geometry.

Under Cover? No Problem.

The intrusive complexes in this example are not exposed at surface. They are concealed beneath lower-density sedimentary cover.

Yet the FTG signal clearly resolves

  • Intrusive footprints

  • Contact geometries

  • Fault corridors

  • Structural intersections


For gold exploration and strategic mineral targeting, this is critical. Surface mapping alone would not reveal this architecture.

Data for Decision Making.

All geological and mineral occurrence data used in this example are sourced from the nations Geological Survey’s publicly available datasets. The match between structural interpretation and documented gold occurrences validates the approach.

But this is just a simplified image for a booth display. 

Behind it lies a far more detailed structural and density interpretation framework capable of:

  • Ranking intrusive complexes

  • Mapping fault connectivity at scale

  • Identifying mineralised margins

  • Prioritising drill targets in covered terrain

Anywhere density contrasts and structural controls define the mineral system, FTG provides a strategic advantage.
