| Abstract | About 450 bulk stream silt samples were collected from 1985 to 1987 for a resource assessment of proposed extensions of the Nahanni National Park Reserve. For the study reported here, 211 of these
samples were passed on a water1ed concentrating table to recuperate heavy mineral concentrates (HM Cs) for neutron activation analysis. Results were compared with previous analyses of standard stream silts and HMCs prepared from sandy gravels taken
at the same sites. The HMCs from silts confirmed a gold anomaly at Wretched Creek which had been identified by the HMCs from sandy gravels but missed by standard silt samples. The HMCs from silts also identified 6 new placer gold anomalies: Jackfish
River, Windy Creek in Liard Range, a small tributary to Nahanni River at the south end of Nahanni Karst, and 3 tributaries in Ram Plateau. Base metal values from the two different sets of HM Cs parallel those of the standard silt samples and spring
waters. |
