Work History

Staked as Bruce, etc cl (85292) in August 1963 and as Merg, etc cl (90684) in September 1964 by Meridian Syndicate (Canex, Noranda & Homestake) under an option of the adjoining Revenue property and explored with mapping and geochemical surveys in 1964.

Re-staked in November 1968 by G. Harris as Porphyry cl (Y29990) and bulldozer trenched in 1969 by Harris and in 1970 by Kaiser Res L & Yukon Revenue ML under option. Fringe staking includes Kook cl (Y38347) in October 1969 by Montana ML, which was explored with geochemical sampling in 1969 and bulldozer trenching in 1970, and Bow cl (Y40571) of Golden Gate EL to the south, explored with an airborne geophysical survey and geochemical sampling in 1970 and bulldozer trenching and more sampling in 1972.

Re-staked as Sey and Bir cl (Y79032) to the north in June 1974 by Conjuror Bay ML, and Zit cl (Y91786) to the south in December 1974 by Klotassin JV (Newconex, Marietta Res Int L and Molybdenum Corp of America), which performed mapping and geochemical sampling in 1975.

Re-staked as Sharon cl (YA82032) in June 1984 by Shakwak ECL, which performed mapping and sampling later in the year. Re-staked in August 1987 as Out cl (YB7655) by R. Stack.

Regional & Property Geology

Metasedimentary Paleozoic roof pendants occur in an area that is mostly underlain by Jurassic Long Lake monzonite, Mid-Cretaceous Whitehorse suite granodiorite and Late Cretaceous Prospector Mountain syenite plugs and stocks (AR 090087; Allan & Friend, 2018).

No mineralization has been found although a copper-molybdenum soil anomaly was outlined on the Bow group and Conjuror Bay reported that low gold assays were obtained from magnetite bearing float. A pyritic shear zone that crosses the southeast corner of the Zit group is probably an extension of a major northwest-trending fault that can be traced along the lower slope of Mt. Freegold (AR 090087).
