Location: The Puzzler prospect is at an elevation of about 500 feet, about 0.3 mile south of the center of an unnamed lake in the upper half of section 11, T. 72 S., R. 87 E. The location is accurate.
Geology: As described by Wright and Wright (1908), the Puzzler prospect was explored by a 180-foot tunnel in greenstone and greenschist. At 60 feet, the tunnel intersected a quartz vein. The vein is parallel to the foliation of the host rocks, which strike N50E and dip 60 SE. The deposit reportedly has two sets of veins similar to those at the Gold Standard Mine (CR081). One set is parallel to the foliation of the host rocks and the other is oblique to the foliation. Slip planes parallel to the foliation and faults are common. There has probably been no work at the prospect since before 1908 and there is no record of production. The highest value in several samples taken during a recent study of the the district contained 51 parts per billion gold across 5 feet (Bittenbender and others, 1993; Maas and others, 1995). The rocks in the area consist of metamorphosed andesite, basalt, agglomerate, and tuff, and minor flysch, shale, and phyllite. Eberlein and others (1983) and Brew (1996) consider them to be Paleozoic or Mesozoic in age; Gehrels and Berg (1992) tentatively mapped them as Jurassic or Cretaceous.
Workings: A 180-foot tunnel and several trenches and prospect pits.
Age: The quartz veins cut country rocks that may be as young as Cretaceous or as old as Paleozoic.
