Part of a trainload of mining equipment enroute to the gold fields. The outlook for the placer industry in the next decade is bright indeed. Gold prices, although fluctuating daily, remain high; there are more placer claims held at present than at any time in the Territory's history; and the number of pieces of heavy machinery being readied ...

The 1849 California gold rush brought gold seekers from American and many countries to the San Francisco area. Excitement combined with new international tools and methods made the rush a time of possibility and opportunity. By 1855, the mines slowed down having produced nearly $2 billion in gold.
Many amateur miners were farmers who also did part-time placer mining, or shallow surface mining, on their property when not busy with farm business. North Carolina gold mining swiftly evolved from the placer mining of streambeds to the much more involved shaft mining that would become prominent in the California gold rush.
The early years. The early years of the Victorian goldrushes, from 1851 until the end of the decade, was the era of small, unmechanised alluvial mines that relied on muscle-power and physical endurance. Diggers arrived at the goldfields with little mining experience. By watching other miners and veterans from the Californian rushes they …
includes a chapter on early gold mining techniques from across Australia, and includes a wide range of images showing mining technologies from the 1850s onwards. Life cycle of a goldmine. an …
Oil Wick Cap Lamp (Circa 1860) by Archive Material Hutchings Museum Institute. Oil wick lamps required a fuel mixture of fat and oil. As miners were always quite poor, they would use the cheapest fuel they could buy. Cheap fuel produced a smoky flame which caused the miners faces and clothes with soot.
What are tools gold miners use? 1 Stamps. Stamps were used in California gold mines around 1850. 2 Rockers. A rocker, also known as a cradle, separated gold from dirt. 3 Pickaxes. Pickaxes were known as the gold standard for early mining in the 1800s. 4 Drills. Miners drilled by hand or used compressed air drills.
A rich gold-bearing river that flows for hundreds of miles is hard to miss. Once gold was found, miners would prospect all throughout the river system in search of gold. Not all gold deposits are like this though. Sometimes gold is found is small "patches" or "pockets.". These are places where gold formed in relatively small quantities.
The change in mining techniques is really the story of the evolution of the Gold Rush from an individual to a corporate phenomenon. A few years after 1849, when hydraulic jets …

Image via Shorpy. Miners' lives in the late-1800s were absurdly dangerous, large in part because many technologies we now take for granted hadn't yet been invented.

How the Early-Day Miners Sluiced for Gold. During the major gold rushes of the 1800s, the miners did not have the conveniences of modern design and technology like we have today. Things like the modern sluice box that we use today were not available to them, so generally it was much more labor-intensive to set up a placer mining operation.
The change in mining techniques is really the story of the evolution of the Gold Rush from an individual to a corporate phenomenon.
