About this layer

This layer shows the highest recorded gold result for each drill hole. It helps you see where drilling found interesting material below the surface. The best result may be deep underground and out of reach of a detector.

What it is for

Check depth and assay details where available. Compare several holes with the surface geology before drawing conclusions.

Limits

A value from depth may have little bearing on what a detector can reach. The map point usually locates the hole, not each sample underground.
