2021-3-12 The common way gold in quartz is found is when hydrothermal water with both gold and quartz percolate up through the fissures in bedrock that is hot enough to hold both minerals dissolved in solution. Both minerals drop out of solution when the water cools. Quartz falls out of the solution first.

2012-6-25 Gold Mining. A supposed goldfield: Ben Lomond and Tower Hill, 1859 (Tasmaniana Library, SLT) Gold mining began in 1847 when John Gardner found gold-bearing quartz on Blythe Creek, near Beaconsfield.The first payable gold was found in 1852, in alluvial deposits at Mangana, which immediately attracted some 200 fortune seekers.
A quartz vein, hidden inside Beinn Chuirn, contains gold estimated to be worth £200 million. However, several companies have already tried and failed to extract it. The series highlights a crucial period for the latest company, Scotgold, with the emphasis very much on those at the ‘gold’ face including landowner John’s own son Davy.
Individual quartz veins typically range from 20 cm to 1.0 m in width, are steeply dipping, and have been traced on surface for up to 250 m along strike with several vein structures interpreted to project beyond their current mapped extent beneath talus and scree cover. Dominant vein orientations are north-northwest, east-west, and north-south.
The gold-bearing quartz fissure veins on the Winston Property are associated with the late Cretaceous-to early Tertiary age Edna Stock, a 400-by-800 meter porphyry pluton, which intrudes volcanic rocks of similar age and Cambrian to Cretaceous age sedimentary rocks. The most significant was the Custer Vein, which strikes N30E and dips 70N.

2021-4-8 As late as 1861 the majority of Bendigo miners worked on alluvial diggings and only twenty-three percent of the fields 8,744 miners were employed on quartz claims.5 However, the Bendigo gold field continued to be a major producer of gold, despite several lean periods, through until the First World War. This continued prosperity depended, not on the exploitation on easily won alluvial deposits
