Comments on the geologic information

  • Geologic Description = The Top Dollar (TD) claims are situated in the Paleozoic metamorphic rocks intruded by Cretaceous to Tertiary granitic rocks that constitute part of the Yukon-Tanana Uplands metamorphic terrane. The region is transected by regional-scale, northeast-trending shear zones and northeast-trending mafic dikes. Gold mineralization has been observed in the form of gold-arsenopyrite-quartz veins and stockwork zones in host rocks consisting of massive, hornfelsed, micaceous quartzite and schist. The zones are near to the intrusive contact of the Cretaceous 'Two Bit' granite pluton, possibly in mineralized pendants above the pluton. Rock grab samples contain up to 14 ppm gold, highly anomalous arsenic and antimony, and variably anomalous bismuth and base metals (D.D. Adams, written commun., 1998).
