|Location and accuracy||This prospect which was first located in 1997, is south of the middle part of Taylor Creek and about 0.6 mile north of hill 1606. It is about 0.4 mile west-southwest of the center of section 36, T. 59 S., R. 76 E. The location is accurate.|
Geologic descriptionThis prospect was first staked by Kennecott Exploration Company in 1997 based on geophysical and geophysical anomalies and they drilled five holes in 2000. Still and others (2002) examined the property and collected several samples. The rocks in the area consist of calcareous chlorite schist interbedded with calcareous graphitic slate; they are part of the Triassic Hyd Group as mapped by Karl and others (1999). At the surface, the mineralization consists of massive to semi-massive layers of pyrite parallel to the foliation of the host rocks and most of the layers are about an inch thick. Four samples were collected by Still and others (2002). One sample across a 3.0-foot layer of semi-massive pyrite contained 197 parts per billion (ppb) gold, 19.2 parts per million (ppm) silver, 335 ppm lead, and 479 ppm zinc. Another sample across a 0.6-foot layer of semi-massive pyrite in slate contained 453 ppm lead and 2,518 ppm zinc. They considered the deposit to be a volcanogenic massive sulfide deposit similar to others in the area.
