In the past, a gold standard was often implemented as a monetary policy. Gold also dissolves in mercury, forming amalgam alloys, and as the gold acts simply as a solute, this is not a chemical reaction.Ī relatively rare element, gold is a precious metal that has been used for coinage, jewelry, and other arts throughout recorded history. Gold dissolves in alkaline solutions of cyanide, which are used in mining and electroplating. Gold is insoluble in nitric acid alone, which dissolves silver and base metals, a property long used to refine gold and confirm the presence of gold in metallic substances, giving rise to the term ' acid test'. Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Less commonly, it occurs in minerals as gold compounds, often with tellurium ( gold tellurides).
#Gold precipitate series#
It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite.
#Gold precipitate free#
Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, veins, and alluvial deposits. It is one of the least reactive chemical elements and is solid under standard conditions. Chemically, gold is a transition metal and a group 11 element. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. This makes it one of the higher atomic number elements that occur naturally. Channel samples: 0.5m of 4.5 g/t Au, 1.5m of 10.1 g/t Au, 6.2m of 3.6 g/t Au Airborne magnetic geophysics, surface geochemical samples (elevated gold and arsenic) and surface structural lineaments, identifies 7 high priority and 11 secondary target areas Located within Newfoundland's Burin Peninsula, a current gold exploration focus of many other junior explorationists District-scale potential within a 12,350 hectare project, an estimated 16.5-km long exploration trend hosted in late Proterozoic-age Burin Group volcanic and ultramafic rocks Structurally related orogenic gold style mineralization, where gold enriched quartz veins- stockworks are strongly associated with shears, faults and folds containing low pyrite and arsenopyrite sulphide concentrations and Excellent year-round road access, with highway access, a high-power electrical line bisecting the project, and nearby Atlantic Ocean ports.Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79. 11 historical mineral occurrences, including 8 gold showings Select Historical sampling highlights: Rock grab samples: 25.0 g/t Au, 15.7 g/t Au, 11.6 g/t Au, 6.3 g/t Au & 4.5 g/t Au. This initial phase will be followed up with ground geophysical surveys of induced polarization ("IP") and further detailed work to delineate targets for near-term drill testing. The ongoing activity entails project-wide prospecting, geological mapping, and sampling to further assess the 7 high priority, and 11 secondary target areas delineated by previous exploration work, s shown on the accompanying map.
announced it has commenced exploration field work on the Motherlode Gold Project ("Motherlode" or the "Project") within the Burin Peninsula of southern Newfoundland, Canada. Commences Field Work At Motherlode Gold Project in Newfoundland, Canada A total of 330 rock samples have been submitted to the laboratory for analyses. The Company has completed the first phase project-wide exploration program of prospecting, geological mapping and surface sampling, with emphasis on the 7 high priority and 11 secondary target areas outlined in previous news releases. The Motherlode Zone hosts the Project's most notable gold mineralization and related surface colour gossan identified to date, with rock grab sample values up to 25.0 g/t gold and historical drill results including 3.5m at 1.4 g/t gold. These two surveys will cover a 1,000 metre portion of the laterally extensive shear-structure trend which bisects the Zone in a northeast - southwest direction. The IP survey will consist of 11 lines at 100 metre spacing for an estimated total of 7.5 line-kilometers. The Company has initiated a ground geophysical program of magnetic and induced polarization surveying at the high priority Motherlode Zone. announced it has commenced ground geophysical surveying at the Motherlode Gold Project within the Burin Peninsula of southern Newfoundland, Canada.
