| Structure description | There are 2 prominent fracture systems associated with the anticline: one trending NNW, and one NE. some of the NNW fractures have fault offset, down on the west. Original movement was pre-ore, but reactivation occurred during Basin and Range tectonics. |

| Structure description | NNW trending asymmetrical anticline with a vertical west limb and gently dipping east limb. |

| Deposit | Ore consists of finely disseminated crystals of argentite and clots of native silver in a gangue of silicified limestone (jasperoid). Much of the jasperoid consists of breccia fragments. Calcite and quartz occur as late-stage veins and as matrix cement in jasperoid breccia. There are also rarely occurring stibnite, sphalerite, tetrahedrite, chalcopyrite, galena, and pyragyrite. Deposits consist of large tabular masses of argentiferous jasperoid at the top of the Guilmette Limestone. Ore occupies the crest and flanks of a north-trending assymetrical anticline which is the dominat structural feature of the district. Ore is flat-lying on the crest of the anticline, dips vertically on the west flank and dips gently on the east flank. The original form of the ore bodies has been somewhat modified by late movement along N- and ENE-trending normal faults. The orebody averages 50 ft thick. Ore boundaries are "assay walls" with mineralization gradational into host rock. Limonite pseudomorphs after pyrite are common. Silica and silver appear to be contemporaneous and are slightly older than the mid-Tertiary intrusive rhyolite. Solutions entered along fracture systems and deposited minerals in crackle breccia in and near the axis of the anticline, at or near the Gilmette-Pilot contact. A period of calcite deposition followed the ore-forming period. The source of the silver may have been a deep-seated intrusive body, or the Chainman Shale and mid-Tertiary intermediate volcanic flows. |
