Part of Barrick's Goldstrike operations in Nevada.


Structure: N30-35W folding in Late Triassic to Late Jurassic, was important to concentrating mineralization Roberts Mountain Thrust. Separate NNE, NW, and NE fault trends.

Alteration: silicification, argillization, pyritization, dolomitization

Commodity: Ore Materials: gold Gangue Materials: pyrite, silica, dolomite,cinnabar, metacinnabar, barite, sphalerite, stibnite, calcite

Deposit: This is an unusually high-grade deposit. Deposit is divided into a "flat sector," just below the Vinini Fm/Roberts Mtn. Thrust; a "dipping sector" that strikes NW, dips 70 degrees NE; and a south flat-lying orebody.

Deposit type: Sediment-hosted Au

Development: The Purple Vein was originally a mercury prospect in the 1930s. Gold was found by drilling; discovery hole EX89-4 intersected 540' of 0.406 oz/ton Au from 1305' to 1845'. The shaft was developed in 1994-5. Production began in late 1996 and full production was achieved in 1997, and has continued to present.

Geology: Mineralization could be associated with monzonite intrusive (147-162 my). Perhaps due to increased permeability and porosity, best ore in collapse/hydrothermal breccias which are well developed in areas of debris flows. Separate surficial mercury mineralization was probably emplaced by a different (much later) event, using the same conduits. Huge solution/collapse cavities and vugs lined with collector-quality barite and calcite crystals have been encountered in the underground workings of the mine.

Ore(s): Lower plate of Roberts Mountain Thrust and hanging wall of monzonite porphyry; NNW and NW trending faults were possible feeders
