Gold also dissolves in alkaline solutions of cyanide, which are used in mining and electroplating. Gold dissolves in mercury, forming amalgam alloys, but this is not a chemical reaction. A relatively rare element, gold is a precious metal that has been used for coinage, jewelry, and other arts throughout recorded history.
Gold has been treasured since ancient times for its beauty and permanence. Most of the gold that is fabricated today goes into the manufacture of jewelry. However, because of its superior electrical conductivity and resistance to corrosion and other desirable combinations of physical and chemical properties, gold also emerged in the late 20th century as an essential industrial metal.
The gold atomic structure has 79 protons and 118 neutrons in its nucleus. It has 79 electrons. These electrons will exist in determined orbitals around the nucleus. Each orbital can hold a certain amount of electrons; and for gold, each energy level will hold: 2, 8, 18, 32, 18, 1.
Gold Terra drilled 5 holes within a one kilometre gap between its Sam Otto Main and Sam Otto South Zones. (Figure 1) This gap had only one previous drill hole completed in 2018 (TSO18-039) which indicated that the gold mineralizing structure was likely to extend between the two NI43-101 mineral resource zones.
Although the best intersection in this area was only 1.27 g/t Au over 4.50m, the confirmation of the gold bearing structure opens up a large area for further exploration and expansion of Sam Otto.
