WebNov 15, 2012 · Porphyry-type ore deposits are major resources of copper and gold, precipitated from fluids expelled by crustal magma chambers. The metals are typically concentrated in confined ore shells within vertically extensive vein networks, formed through hydraulic fracturing of rock by ascending fluids. Webabundance of porphyry-related, sugary to granular, A- and B-type quartz veins are one of the best indications of proximity to a porphyry centre. These key geological indicators are best identified through careful geological mapping techniques, such as the ‘Anaconda Method’ (Einaudi, 1996; Brimhall et al., 2006; Garwin, 2024).
