Special Mining Lease 199 was one of three leases taken up by Kennecott Explorations (Australia) Pty Ltd in the Mount Painter district during 1968, to evaluate one known copper-uranium deposit (Shamrock Valley, SML 236), and to search for new occurrences. An airborne gamma-ray spectrometer survey flown over the lease area disclosed two major uranium anomalies and another of lesser magnitude. The anomalies were all located near the boundary of an Ordovician granite intrusive on which the lease was centred. The largest area of anomalous radioactivity, covering approximately one square mile of greisenised granite and granite contact rocks on Freeling Heights at the northern boundary of the lease, yielded surface samples assaying from 0.2 to 0.6 lbs U308 per ton. Chip line sampling confirmed widespread, low grade uranium mineralisation of the order of 0.1 to 0.4 lbs U308 equivalent per ton. Follow-up diamond drilling (3 holes totalling 381 feet) showed that surface grades were comparable to the grades of fresh sub-surface rock; a very slight and inconsequential veneer of uranium enrichment was indicated in surface rock. The second significant anomaly was located at the British Empire mine, near the southern boundary of the lease. At this locality secondary uranium minerals were found to be deposited in fractured greisenised metasediments near the granite contact. Surface mapping and sampling proved that this quite localised zone had a small potential tonnage of one to three pounds per ton of uranium oxide ore. The third but lower order anomaly was located near the edge of the granite intrusive, on the eastern side of the lease. Chip-line sampling confirmed that an area of weakly uraniferous granite gave rise to the anomaly. The occurrence did not warrant a detailed investigation.
