Location and accuracy The Chicago Kid and New Era prospects have rarely been described since the early 1900's. Either one may coincide with the 'James Lake West' prospect described by Maas and others (1992, 1995). The site is just west of James Lake, about 0.3 mile southeast of the center of section 31, T. 77 S., R. 89 E.

Geologic setting

Geologic description

Chapin (1916) describes the Chicago Kid prospect as 5-foot-wide quartz vein exposed in a shallow pit in brecciated limestone. The vein strikes N60E and dips 70SE and contains minor pyrite and tetrahedrite. The New Era prospect, which was explored by an adit, is a 30-foot quartz vein with disseminated pyrite; it strikes N30W and dips vertically. Maas and others (1992, 1995) described workings in this vicinity under the name 'James Lake West'; the workings consist of a 10-meter adit, trenches, and cuts. A quartz vein 12 feet thick can be traced for about 600 feet. Samples contained 8.1 to 54 parts per billion gold.
The rocks in the Dolomi area are part of the Wales Group of Late Proterozoic and Cambrian age (Herreid, 1967). They are folded into a large dome centered over the eastern third of Paul Lake, and consist of several marble layers 200 to 1300 feet thick, interbedded with calcareous chlorite schist and marble.
