Yesterday I shared how we design exploration workflows to converge on a drill decision (not just collect more data).
Today, here’s a concrete example of what that looks like in asphalt/bitumen vein exploration — and why remote sensing is often the fastest way to move from “interesting area” to actionable targets.
In the attached interpretation map:
Dark blue = remotely interpreted asphalt veins or vein corridors
Black = a known vein (used as ground truth)
Light blue = a key fault \ structural control
What mattered most was not a single index or image product. The interpretation was the integration of spectral and structural evidence:
Remote sensing picked out the right corridors
We mapped subtle surface expression and continuity of vein-like features across rough terrain and variable cover.
Structure controlled the mineralization
The interpreted vein network aligned with a major fault zone.
Verification closed the loop
Field mapping later confirmed the predicted vein positions and trends, and drilling validated the model, reducing targeting uncertainty and saving time compared to blind step-outs.
Remote sensing isn’t “pretty maps.” When used properly, it becomes a decision engine; narrowing the search space and ranking targets before boots hit the ground.
