Report: North Boulder Lead Quartz-pyrite-galena breccia in a gouge zone was mined, probably for its silver and lead content. A select sample (JJPB-1) contained .005 oz/ton gold, 1.65 oz/ton silver, .022% copper, .48% lead, and .145% zinc. A discharge emerges from the shaft and precipitates iron hydroxides in wetland, but the site is on private land.
