Comments on the geologic information

  • Geologic Description = By 1916, four zones as much as 14 feet wide that contained scheelite had been discovered on the western periphery of a large granite body (Mertie, 1917, p. 422-424). Scheelite occurs in tactite, silicified limestone, granite and pegmatitic dikes, and in small quartz veins in schist (Berg and Cobb, 1967). Samples of high-grade ore on the dump assayed 8percent tungsten trioxide (WO3) (Joesting, 1943 [ATDM Pamph. 2]). This prospect is near the contact of a Cretaceous porphyritic granite and Fairbanks Schist that consists of quartz-muscovite schist, quartzite, and chloritic-quartz schist (Newberry and others, 1996).

Comments on the workings information

  • Workings / Exploration = By 1916, several zones that contained scheelite were located. On the Grand Duke Nikolas claim, a scheelite lode in schist was exposed in an open cut. On the Tungsten No. 1 claim, another open cut had been made in schist and quartzite schist that included a zone with scheelite. The width of the mineralized zone was not apparent. On the General Joffre claim, a lode 14 feet wide with scheelite has been exposed. This deposit as a whole was considered low-grade ore (Mertie, 1917, p. 422-424). In 1943, Joesting (1943 [ATDM Pamph. 2]) reported that little work had been done since 1918.
