Comments on the geologic information

  • Geologic Description = The Blossom tungsten prospect is along the western edge of a large mass of porphyritic granite that intrudes quartz-mica and amphibole schist. By 1918, a quartz stringer rich in scheelite was found in the bottom of a shaft in granite porphyry (Mertie, 1917). Another shaft 20 feet deep, opened a scheelite lode that was 3 to 4 feet thick (Mertie, 1917). Select samples from dumps contained 1.44 percent and 2.02 percent tungsten tri-oxide (WO3) (Byers, 1957). Mulligan (1974) characterized this prospect as containing pegmatite-type quartz-scheelite stringers that cut quartz-biotite schist and porphyritic granite. Workings consisted of two shafts and 23 trenches and pits, all of which were caved by 1942 (Byers, 1957, p. 201). Dozer trenching took place in 1951 in an effort to expose scheelite mineralization (Williams, 1951).
