Unknown Samples in the Detector Maps app, Western Australia

Satellite imagery © Mapbox, © Maxar. Layer data from the sources named on each card.

About this layer

These sample records are grouped separately because their sample type is other or unknown. Read the individual record and units before using the result. Do not assume it was collected from soil, a creek or surface rock.

What it is for

Check the sample type, element and units in the legend before comparing readings. Look for patterns across nearby samples.

Limits

Sampling methods, depth and laboratory detection limits can differ. A high reading alone does not show a detectable nugget.
