Coarse placer gold was discovered in Skaret Creek during 1931 following which several claims were staked and explored. The coarseness of the gold indicated that the bedrock source was proximal. During the same year, pyritic quartz stringers were discovered in andesitic volcanic rocks which also hosted disseminated molybdenite.

stringers oriented normal to the first set of quartz angular stringers at 55º to the core axis. The last set consists of thicker, 3 -6 mm, regularly spaced, thin veins oriented sub -parallel to the first set of stringers at 40º to the core axis and 40º to bedding. Another interesting section of the core is shown in Figure 3.

Two types of gold mineralization occur: high-grade, quartz stringer and breccia zones and low-grade, stratiform horizons of carbonate-rich metavolcanic rock. The quartz stringer zones are oriented along D2 fabric, predominantly in the metasedimentary rocks, within a major shear zone,

Gold in Quartz - February 2016 (Vol. 85, No. 06) - ICMJ's ...

Gold in quartz veins occurs as particles and scales scattered through the quartz, often filling cracks and openings in the vein material. The gold can be such small particles as to be invisible to the naked eye, or as larger aggregates of easy to see blobs, leaves and crystals in cavities in the quartz. The gold fills cracks and spaces in the ...

Age and Geologic Setting of Quartz Vein-Hosted Gold ...

The gold resource is contained in a suite of quartz sulfide veins hosted by Neoproterozoic (Dalradian) meta-sediments, which have been thrust over an Ordovician island arc (Tyrone Igneous Complex). Previous studies recognized two generations of gold sulfide mineralization and we have identified a third in microshears that cut the veins.

Geology of Quartz Deposits - Mineralogical Society of America

The lode is composed of a system of quartz stringers, veins, and lenses occupying a position in the shale adjacent to the granite. Horses of shale are common. Along the contact and decreasing away from it into the hanging wall, the shale is somewhat folded and distorted with extremely variable dips.
