South Liberty Prospect, Fortymile District, Southeast Fairbanks Borough, Alaska, USA
The South Liberty prospect is located within Doyon, Ltd. selected or conveyed land. For more information contact Doyon, Ltd., Fairbanks, Alaska.
Location: The South Liberty prospect is located in a road cut one-half mile south of the settlement of Liberty along the Taylor Highway. The coordinates are the approximate location of the road cut, in section 16, T. 5 S., R. 33 E., of the Fairbanks Meridian. The location is accurate. The South Liberty prospect is located within Doyon, Ltd. selected or conveyed land.
Geology: The South Liberty prospect is in Paleozoic greenstone, Paleozoic or Mesozoic serpentinite, and Permian quartzite and argillite (Foster, 1976). The prospect consists of iron-stained quartz-carbonate veins that cut greenstone and quartz-muscovite schist (WGM Inc., 1998 [DLR 98-12]). Soil samples were collected by WGM Inc. in 1990 (WGM Inc., 1998 [DLR 98-12]). One soil sample contains 7,517 ppb gold, 27.1 ppm silver, 2,000 ppm arsenic, 277 ppm antimony, and 176 ppb mercury; an adjacent soil sample contains 2,130 ppb gold, 9.8 ppm silver, greater than 10,000 ppm arsenic, 420 ppm barium, and 64 ppm antimony. Rock samples contain as much as 2,780 ppb gold, 8.8 ppm silver, greater than 10,000 ppm arsenic, and 104 ppm antimony. The South Liberty prospect is within a northeast-trending group of magnetic anomalies that extends for about 15 miles (WGM Inc., 1998 [DLR 98-12]). The magnetic anomaly indicates a southwest trend to greenstone and suggests a relation to the Howard prospect (EA072), three-quarters of a mile to the north. Three strong EM conductors are parallel to faults adjacent to the magnetic anomalies. The prospect may be a Cyprus-type massive sulfide deposit or a greenstone-related, Mother Lode-type-gold deposit (WGM Inc., 1998 [DLR 98-12]).
Workings: Soil samples were collected by WGM Inc. in 1990 at the South Liberty prospect (WGM Inc., 1998 [DLR 98-12]).
Age: Paleozoic or younger.
