Work History
Staked as TLC cl (Y64038) in August, 1971 by L.L. Heisz. Restaked by A. Black as Alpha cl (Y83151) in July, 1974 and as Tim cl 1-4 (YA71552) in August, 1984.
Cominco Ltd staked River cl 1-40 (YB71103) 8 km to the west in November, 1995 to cover airborne geophysical anomalies identified in a survey flown the previous year. The claims extend north onto map sheet 105H 04. Cominco carried out a program of soil and silt geochemistry, geological mapping and prospecting in 1996. In 1997, Cominco carried out HLEM and magnetic surveying and drilled one hole (203.6 m).
Capsule Geology
The occurrence lies within the Yukon Tanana terrane (YTT): a Late Proterozoic to Paleozoic metamorphosed volcano-sedimentary assemblage. It is regionally bounded to the southwest by the Tintina Fault. This terrane hosts several known volcanogenic massive sulphide (VMS) deposits and occurrences, including Kudz Ze Kayah (MINFILE occurrence 105G 117), Wolverine (MINFILE occurrence 105G 072) and Ice (MINFILE occurrence 105G 118).
The occurrence area has not yet been re-mapped by the Yukon Geology Program. According to Gordy and Makepeace (1999,) the target area is underlain by Late Devonian to Mississippian protomylonite and mylonite derived from hornblende granodiorite to quartz diorite; granite gneiss of the Pelly Gneiss Suite (unit DMgPE). These rocks are flanked to the west by Carboniferous and Permian basalt, diorite and gabbro, chloritic greenstone, amphibolitic greenstone and amphibolite and various metasediments.
Mapping and prospecting by Cominco discovered several areas with significant felsic volcanics thought to be equivalent to the Grass Lake or Upper Succession of the YTT as mapped by Murphy and Piercey (1999) in the Finlayson area. The soil and silt geochemical survey returned anomalous values for Ni only. Drilling in 1997 of the strongest HLEM/magnetic feature intersected mostly carbonaceous siltstone and argillite with minor pyrrhotite mineralization.
