Gold is found in small concentrations in metamorphic rock, and occasionally some is eroded out by weather and may be found as placer nuggets or gold dust in streambeds and such. Probably the most gold is found in the seas. Although it only is found in concentrations approximating 1 x 10 to the negative 19th moles per liter, there is so much seawater that the amount of gold found there would be much more than all the present stores of refined gold on earth.

http://en.wikipedia.org/wiki/Grasberg_mine
The Grasberg mine is the largest gold mine in the world and the third largest copper mine in the world. It is located in the province of Papua in Indonesia near 4°03′10″S, 137°06′57″E, and is owned by the Freeport-McMoRan company based out of the United States. The cost of building a mine on a mountain was 3 billion United States dollars. In 2004, it was estimated to have reserves of 46 million ounces of gold.

Australia
In 1851, during the time that there was a gold rush in California, a gold rush began in Australia. The gold in California was mainly in the form of very fine grains, called gold dust. However, in Australia, it was not unusual for gold nuggets, some very large, to be found.
In October 1872 Holtermann's Nugget was found. At that time it was the world's largest specimen of reef gold. It weighed 286kg and measured 150cm by 66cm.
The Australian gold rush begins
Small amounts of gold were found in New South Wales in the early days of the colony, but the authorities hushed it up. However, in February 1851 a man named Hargraves found gold in near Bathurst, and word quickly spread. Within a week there were over 400 people digging there for gold, and by June there were 2000. They named the goldfield Ophir after a city of gold in the Bible. The Australian gold rush had begun!
So many people went to the goldfield that there was a shortage of people doing other work such as farming, building, baking and so on. Governor Fitz Roy was worried that there would be violence and lawlessness at the goldfields, and he ordered that gold seekers must pay for a licence in order to dig for gold.
The Victorian goldfields
In August 1851, part of New South Wales was made a separate colony, and was named Victoria after the Queen. Many Victorians had gone to the goldfields, and businessmen, to keep people from leaving the new colony, offered a prize of 200 guineas for the first person who found gold in Victoria. At around the same time, gold was found at Clunes, at Andersons Creek near Warrandyte and at Buninyong. Towards the end of August, James Reagan and John Dunlop discovered the richest goldfield the world has ever seen in a place the Aborigines called Balla arat, which means 'camping place', now the city of Ballarat. Other discoveries soon followed in Mount Alexander, now called Castlemaine, in Daylesford, Creswick, Maryborough, Bendigo and McIvor, now called Heathcote.
By the end of September 1851, there were about 10,000 people digging for gold near Ballarat. By 1852, the news had spread to England, Europe, China and America, and boatloads of hopeful diggers arrived in Melbourne and headed for the goldfields. Between 1851 and 1861, Australia produced one third of the world's gold

Gold is found where magma intrusions occur at or near the earth's surface.
In igneous and sedimentary rocks, the most widely accepted hypothesis is that gold deposits are formed from circulating ground waters driven by heat from bodies of magma intruded into the Earth's crust within about 2 to 5 miles of the surface.
In igneous rock, gold-bearing solutions are expelled from magma as it cools and the gold is precipitated as it moves into cooler rocks.
In metamorphic rock, gold is usually found in mountain belts located near continental margins.
