New Mexico History
Placer mining is a method of extracting valuable minerals from loose material, such as sand and gravel, where these minerals have accumulated due to weathering and erosion. This technique relies on the movement of water to separate heavier minerals, like gold or gems, from lighter materials. It's often associated with gold rushes and is significant in the context of mining and extractive industries as it allows for the recovery of precious metals without extensive tunneling or excavation.
