Location: The Blossom prospect is located in the SW1/4NW1/4 sec. 3, T. 1 N., R. 1 E., Fairbanks Meridian. This prospect is at the head of Engineer Creek on top of Mount Lulu Fairbanks, about 1 mile southwest of Tungsten Hill. The prospect is near a residential area off Gilmore Trail and north of Flat Rabbit Road (which is not shown on the (D-2) NE map). The prospect is included in locality 27 of Cobb (1972 [MF 410]). This prospect is included in locality 27 of Cobb (1972 [MF 410]).
Geology: 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).
