For these early techniques, water was an essential part of the process. However, since gold was not always found next to streams, miners often had to get the water to where the gold was, and thus eorate nets of mining ditches were built throughout the gold country; remnants of these ditches can be found even today, and now some are used for agriculture.
The earliest gold mining was done by hand, using a hammer and a pick or a gold pan. The first use of machinery in the gold rush was in the 1860s at an underground mine in Tangier. The machine, called an arrastre, used a giant stone attached to a en arm, moved by a horse, to crush the gold-bearing rock. It was designed to speed up the crushing of the quartz ore.
Panning. Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material.

Taking gold out of a slu box, western North America, 1900s Using a slu box to extract gold from placer deposits has long been a very common pract in prospecting and small-scale mining. A slu box is essentially a man made channel with riffles set in the bottom.

An arrastra, also known as a Mexican Rastra, was a primitive method used by early miners to process gold and silver ores. It was introduced to the new world by the Spanish in the 1500’s. They were used throughout the world, often at remote locations where other processing methods were not feasible.
Sep 29, 2017· Panning for gold was also known as "placer mining." Early miners sat by riverbeds, scooping wet soil into shallow metal pans. They swirled the pans, washing away the dirt to hopefully discover particles of gold. Though more complex equipment was eventually invented, pans were still a useful tool to distinguish gold from dirt.
