The relationship between the Eucalyptus root system, regolith stratigraphy and location of the Freddo Au deposit is shown. Circled numerical data in foliage corresponds to typical sample location and bulk Au analyses of leaves. Note the unconformity (marked by presence of rounded river pebbles) at 30 m depth beneath which is the weathered bedrock containing the Au deposit.
