There were more than two mining methods used during the gold rush. Diggers in the gold rush used the following equipment and methods to find gold :
The majority of people that joined the gold rush were placer miners. Meaning they would dig up the soils that had been deposited along stream beds and use hand methods to separate heavy particles (like gold) from the rest of the material they dug up. The gold pan being most common. Another popular method was to outfit a barge like object with the means to dig up stream beds below water and use sluices or jigs to separate gold. this is called dredging. The most gold was recovered in hard rock mines, where gold miners usually worked for a mining company that chased quartz veins that run through fractures in bedrock. They created deep underground tunnels to get to the veins, always looking for the mother lode. So this was sometimes called a lode source or lode mining. The good ore was sent to stamp mills and separated from the gangue near the mines using gravity separation or flotation techniques. I guess the 4th method was extracting gold from the miner's pockets at the various boom towns that sprang up near the gold rush sites. This was by far the most profitable, using booze, gambling, and prostitutes as the means to capture the gold.

2 - placer mining by dredge
3 - hard rock mining using tunnels & shafts
4 - open pit mining using dynamite

Much more gold has been found in recent years than was found in the Gold rush of 1849. Mostly because of modern mining methods not available to the miners in 1849 (such as heap leaching.) I read in a mining magazine that more Gold was found in 1994 than any year in this country's history.

Actually, the gold rush did not begin until 1851. Methods of extraction included panning, which was the most common method; cradling, which was introduced by Edward Hargarves after he saw the method used in California; puddling; and shaft mining.
