Gold is a chemical element with the symbol Au (from the Latin aurum, meaning shining dawn) and atomic number 79. It is a highly sought-after precious metal which, for many centuries, has been used as money, a store of value and in jewelry. The metal occurs as nuggets or grains in rocks, underground "veins" and in alluvial deposits. It is one of the coinage metals. Gold is dense, soft, shiny and the most malleable and ductile of the known metals. Pure gold has a bright yellow color traditionally considered attractive.
Gold formed the basis for the gold standard used before the fiat currency monetary system was employed by the International Monetary Fund (IMF) and the Bank for International Settlements (BIS). It is specifically against IMF regulations to base any currency against gold for all IMF member states. The ISO currency code of gold bullion is XAU.
Modern industrial uses include dentistry and electronics, where gold has traditionally found use because of its good resistance to oxidative corrosion.
Chemically, gold is a trivalent and univalent transition metal. Gold does not react with most chemicals, but is attacked by chlorine, fluorine, aqua regia and cyanide. Gold dissolves in mercury, forming amalgam alloys, but does not react with it. Gold is insoluble in nitric acid, which will dissolve silver and base metals, and this is the basis of the gold refining technique known as "inquartation and parting". Nitric acid has long been used to confirm the presence of gold in items, and this is the origin of the colloquial term "acid test," referring to a gold standard test for genuine value.
A one ounce gold nugget will bring $2,000 to $4,000 on the collectors market. Per a letter from the Department of Agriculture, no permit is needed for recreational gold panning and gold prospecting in the general national forest areas, provided no machinery is used. Our gold panning and prospecting maps show many national forests with gold sites.
The gold maps tell you how to pan, where to look in a streambed and how to tell fool's gold from real gold. You can quickly learn to pan by following the instructions on your map. Some people like to pan for gold at public rights of way where bridges cross gold-bearing streams. Treasure hunters metal detect for coins at the rural schools and churches.A streak of gold mines and gold prospecting sites extends from near Montgomery, Alabama to Washington D.C. The gold was placed there when Africa overrode North America about 250 million years ago. North Carolina, South Carolina, Georgia, Virginia and Alabama have many gold mines and prospecting sites. These states were our main source of gold for 45 years before the California gold discovery. In 1837, the US Government established gold coin mints in Georgia and North Carolina, rather than transport the raw gold to the Philadelphia Mint.The largest true California gold nugget weighed 54 pounds. A 195 pound mass was also found.
The 6,600 gold deposit sites shown on our six California gold prospecting and panning maps are continuous from Mexico to Oregon and to the Arizona and Nevada state lines. All gold sites on the prospecting and panning maps are from official records.
