Supplementary Figure S1: Gold variability in leaves at site RD 50 from Freddo Au deposit.
Foliage samples were collected using a cherry-picker and leaves separated from twigs in the laboratory. Data show concentration of Au (in ppb) of leaves from ten samples (RD 50T1- T10). Samples collected from background site RD 68 were collected in a similar way. Tabulated data is shown in Supplementary Table S2.
