Location and accuracy This prospect is located along the left fork, right limit of an unnamed creek directly north of Porcupine Dome in the SE1/4 NE1/4 sec. 8, T. 8 N., R. 11 E. This creek is unnamed on the U.S.Geological Survey map, but it is commonly known as Dome Creek. The creek labeled as Dome Creek on the U.S. Geological Survey Circle C-4 quadrangle map is incorrectly labeled; it has been referred to as West Dome Creek in some reports (Freeman and Adams, 1989, p. 12).

Geologic setting

Geologic description

Mineralization in the area occurs in quartz veins, stockworks, and breccia hosted by intermediate intrusives, metaquartzite, pelitic calc-schist and metavolcanic schist of the Bonanza Creek sequence. Stockwork silicification and quartz-sericite-sulfide alteration are developed on the north flank of Porcupine Dome (Freeman and Adams, 1989).
Hand trenching completed in 1989 and subsequent years released float boulders bearing free gold. The gold in rocks is associated with silver, arsenic, lead, antimony and zinc. Fire assay results from vein and stockwork mineralization average 2.96 ounces of gold per ton with a high value of 23.4 ounces of gold per ton. Exploration along strike of mineralization revealed a honey-comb stockwork and white quartz breccia similar to those on Porcupine Dome (Freeman and Adams, 1989).

Production and reserves

Workings or exploration Hand trenching completed in 1989 and subsequent years released float boulders bearing free gold. The gold in rocks is associated with silver, arsenic, lead, antimony and zinc. Fire assay results from vein and stockwork mineralization average gold 2.96 ounce of gold per ton with a high value of 23.4 ounces of gold per ton.

Indication of production Undetermined

Additional comments

Vein and stockwork mineralization on the Weitchy Prospect represents a high grade, moderate tonnage exploration and development target (Freeman and Adams, 1989).
