|Location and accuracy||The Griffin prospect is about 1/2 mile northwest of Money Knob in the NW1/4 section 23, T. 8 N., R. 5 W., It is about 1 mile south of Livengood, near the trail marked on the southeast corner of the Livengood (C-4) quadrangle.|
This small old prospect is now part of the large International Tower Hills, Livengood prospect (LD202) that has been intensely studied and drilled since 2006. The Griffin prospect has largely now lost its identity and the data in this record has been integrated into the Livengood record. This record has not been updated since the exploration stated on the Livengood prospect and the pre-Livengood information here is retained in its original form for historical reference.The Griffin prospect consists of a massive, sulfide-bearing, green-stained silica-carbonate-talc rock veined by quartz ; samples contain as much as 3.9 ppm Au, 1,000 ppm Ni, and 1,000 ppm Cr (Foster, 1968, p. 2, 10-11). A fire assay of one sample showed 5.6 ppm Au (Foster, 1968, p. 10-11). The nature of the contact between pyritiferous metasedimentary country rock and silica-carbonate-talc rock is not known (Foster, 1968.) Small pits expose chromite in serpentinite, and a stibnite vein was uncovered in a placer cut (Joesting, 1942 [ATDM Pamph. 1]; Mertie, 1918).
