URANIUM: Anomalous amounts of uranium are broadly associated with beryllium ore but, at the Roadside ore body, the principal uranium anomaly (100-200 ppm) underlies beryllium ore. The major thorium anomaly (100-150 ppm), in contrast to uranium, follows beryllium ore. Below the beryllium ore, thorium levels decline to crustal background values.
