Although a local origin of Irish Bronze Age gold artifacts has never been confirmed, the widespread distribution of gold particles in stream gravels suggests a local bedrock origin. Significant bedrock mineralisation was discovered in County Monaghan in the 1950s, and in County Tyrone in the 1980s. The Tellus geochemical surveys have revealed the wide distribution of anomalous concentrations of gold in deep soils and stream sediments throughout the region. In addition to prominent anomalies surrounding the already known bedrock occurrences, clusters of anomalies are found in the Lower Palaeozoic rocks of north County Down and in counties Monaghan and Cavan; in counties Sligo and Donegal; and associated with postulated north–south lineaments in counties Tyrone and Londonderry. Tellus geophysical data complement the geochemical data by providing information on geological structures, particularly where these are concealed by glacial overburden and peat. A conceptual understanding of mineralisation processes and field experience of mapping prospective rocks are essential for optimising the value of the Tellus information in future exploration.
