Location: This placer deposit is near the mouth of the locally named middle fork of the stream that flows in Broxson Gulch (see figure 2 of Rose, 1965). The location is for the approximate midpoint of the mine, at an elevation of about 3,550 feet in the N1/2 section 25, T. 18 S., R. 8 E., Fairbanks Meridian.
Geology: The lower middle fork of the stream that flows in Broxson Gulch probably flows across complexly intermixed and faulted peridotite and gabbro of the Upper Triassic ultramafic-mafic intrusive complexes and metasedimentary and metavolcanic rocks of the Slana Spur Formation of Late Paleozoic age (Rose, 1965, figure 2; Nokleberg and others, 1991). The placer deposit was test mined in 1996 and 1997; gold and abundant gray nuggets were recovered. The gray nuggets, originally supposed to be platinum metals, are galena (W.T. Ellis, unpublished data, 1997). The source of the placer gold is uncertain.
Workings: Small-scale placer mining occurred in 1996-1997. The area is on active MAN Resources claims.
Age: Holocene.
Production: Small-scale placer mining occurred in 1996-1997, with 'fairly good results' (W.T. Ellis, unpublished data, 1997).
