California Miners Locate Rich Pocket of Specimen Gold
February 2005 by Scott HarnOver fifty pieces of dendritic gold, ranging from 1 gram up to 2.5 ounces, were recently discovered at a mine in the Allegheny Mining District in Northern California.
Over one hundred years ago, gold mining in California saw a radically new method tried out in the major rivers of the Central Valley. Large gold dredges floated lazily but noisily on the waters, bringing up the rich gravel from deep below. With none of today’s environmental restrictions on such methods, the landscape was reworked into a maze of patterns along the rivers.
Prospectors and investors looking for a stake in the mining sector should turn to Quebec, as La Belle Province is seen by mining executives as having the best policy environment in the world for investment...
The majority of the gold produced in Goldfield has come from ores that are close enough to the surface to be oxidized by the air. This oxidized ore is normally a soft, shattered, earthy material usually stained yellow to brown by oxides of iron.

There are several common ways that new mineral crystals form and grow. Perhaps the simplest is when minerals form through the cooling of molten rock and the atoms bond together into mineral crystals.
