The Howard prospect is located within Doyon, Ltd. selected or conveyed land. For more information contact Doyon, Ltd., Fairbanks, Alaska.
Location: The Howard prospect is in a barrow pit one-quarter mile northwest of the settlement of Liberty, along the Taylor Highway. The coordinates are the approximate location of the barrow pit, in section 9, T. 5 S., R. 33 E., of the Fairbanks Meridian; the location is accurate. The Howard prospect is located within Doyon, Ltd. selected or conveyed land.
Geology: The Howard prospect is in Paleozoic greenstone, Paleozoic or Mesozoic serpentinite, and Permian quartzite and argillite (Foster, 1976). A soil grid tested the extent of mineralized quartz veins exposed in a barrow pit (WGM Inc., 1998 [DLR 98-12]). Rock samples contain as mcuh as 300 ppb gold, 23.6 ppm silver, and 632 ppm arsenic; base metal values are as much as 4,440 ppm lead, 4,320 ppm copper, and 334 ppm zinc. Results of soil sampling do not indicate significant anomalies. Two soil samples collected below a large quartz vein contained as much as 40 ppb gold and 0.6 ppm silver. The Howard prospect is in a northeast-trending group of magnetic anomalies that extend for about 15 miles (WGM Inc., 1998 [DLR 98-12]). A strong magnetic anomaly covers the east part of the soil grid and may indicate the presence of greenstone, which is a favorable gold host in this area. The anomaly extends to the northeast and merges with an extensive magnetic high that spatially corresponds with serpentinite. Three strong EM conductors are parallel to faults adjacent to the magnetic anomalies. WGM Inc. (1998 [DLR 98-12]) suggests the Howard prospect may be a Cyprus-type massive sulfide or a greenstone-related, Mother Lode-type-gold deposit. The South Liberty (EA073) prospect is another gold prospect in the King Solomon Creek area.
Workings: A soil grid at the Howard prospect tested the extent of mineralized quartz veins exposed in a barrow pit (WGM Inc., 1998 [DLR 98-12]).
Age: Paleozoic or younger, on the basis of the age of host rocks.
