  1. At Glenhead and Moorbrock Hill, adjacent to the Loch Doon granodiorite (MRP 48; MEG 261), and in the Leadhills area, quartz veins and disseminated arsenopyrite zones are auriferous (MEG 230 and 260).
  2. The most important have been the Dolgellau area of North Wales, where auriferous quartz veins in Cambrian shales have yielded a total of about 4 tonnes of gold, and the Pumpsaint area of Central Wales where auriferous quartz veins cut pyritic Silurian shales.
  3. In terms of regional structural controls most of the auriferous deposits in the project area are spatially related to first-order faults and shear zones within the belt and along its margins; to major anticlinal fold axial traces and limb shears; or to the fracture envelopes around the major granitoid intrusions Follow-up geochemical field testing of soils for arsenic over selected targets outside the known gold mining districts was 60-;70% successful in demonstrating that certain predicted structural settings would be mineralised.
  4. Not all the quartz veins are auriferous and the Tyndrum Main Vein, previously worked for lead and zinc, does not carry significant gold.
  5. The veins are often auriferous where they cut graphitic shales but not where the host rocks consist of non-graphitic arenites.
  6. In the Suchna-Rudna area, they sampled auriferous quartz veins hosted by carbonaceous Upper Palaeozoic flysch-type sediments in order to make fluid-inclusion studies for comparison with gold deposits in Spain, Portugal and the United Kingdom.
  7. Prehistoric communities and pioneers in new territories concentrated on auriferous alluvial deposits which they could work in small groups or even as individuals with only the most rudimentary equipment.
