Work History
Staked as three adjoining blocks of Leah cl 1-206 (YA13155) in Oct/76 by a syndicate composed of Newhawk Gold Mines Ltd (formerly Highhawk Mines Ltd), Tenajon Silver Inc (formerly Envoy Resources Ltd), Sproatt Silver Mines Ltd, Hecate Gold Corporation and Suneva Resources Ltd (formerly Bow River Resources Ltd), which explored with mapping and geochem sampling in 1977 before optioning the claims to a joint venture between Northgate Mines and Westfield Minerals Ltd, which continued the program later in the year.
The adjoining Star cl 1-32 (YA13367) were tied on to the north in Oct/76 by T. Cross and M. Bratlien and optioned to Prism Resources Ltd, which explored with mapping and geochem surveys in 1977. On the south side, the Lee & Nod cl (YA13915) were tied on in Dec/76 by J.B. O'Neill and optioned to Tay River Mines L, and G. Bleiler added Hill & Don cl (YA15752) in Jul/77. The syndicate conducted more mapping in 1978 and in 1979, Northair Mines Ltd carried out a Maxmin EM survey over the geochem anomalies.
Capsule Geology
The occurrence lies within the Selwyn Basin, a predominantly off-shelf metasedimentary and metavolcanic sequence that formed at the western margin of the North American craton. The area is underlain by Upper Proterozoic to Lower Cambrian siliciclastic and carbonate metasedimentary rocks of the the Hyland Group. Hyland Group rocks are unconformably (?) overlain by Cambrian-Devonian Bouvette Formation limestones and rocks of the Devono-Mississippian Earn Group including black siliceous shale, chert and minor occurrences of felsic volcanic rocks and associated barite. Rocks in the area have been deformed to various degrees by regional faulting and thrusting resulting in younger units being juxtaposed against older units. The south-dipping Dawson Thrust Fault lies to the north.
Several small galena-sphalerite showings and lead-zinc geochemical anomalies are associated with a Late Proterozoic dolomite member of the Hyland Group, in the hanging wall of the Dawson Thrust. Mineralization was also reported from the Star claims. Several conductors were outlined by the 1979 EM survey, some of which correlated with lead-zinc-silver soil anomalies.
