The Borax Method is a technique of artisanal gold mining, with its basis in the principle that borax reduces the melting point of all minerals, including precious metals like gold. The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners.

Gold mining has not been extensive in Texas since the occurrence of the metal is limited. Main production, confined to the Presidio and Hazel mines in West Texas and the Heath mine in the Llano region, amounted to a total of 8,277 fine ounces by 1942, valued at $233,499.

Gold is resistant to weathering, hence is often freed from the surrounding rock and redeposited as sediment. Because gold has a high density, it tends to settle out readily and be trapped with coarser sediments. Where current action is strong, lighter materials are preferentially washed away, concentrating the gold in placer deposits.

Successful gold mining is generally done in two steps: First is sampling or prospecting, and then, production. While some gold-bearing creeks and rivers tend to have gold values dispersed throughout their entire streambeds, there is generally not enough gold to make a small-scale mining …

A rocking motion provides the water movement needed for the gravity separation of gold in placer material. Hard rock mining Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska.

Sometimes placer gold just out of a streambed is very clean and shiny. If this is the case with your gold, after the final dry cleanup procedure is completed, your gold is ready to be weighed and sold or displayed or stored away in a safe place. Sometimes, gold will come out of a streambed with some impurities attached to it.
