Placer mining involves extracting minerals like gold from loose, unconsolidated materials, such as alluvial deposits or sandbars. On the other hand, lode mining involves extracting minerals from hard rock deposits, typically by following veins or deposits of valuable minerals embedded within the rock.
The mother lode is a mining term, referring to the largest lode of ore that has been tapped in a mine. It is used to describe a major windfall because of the large profit associated with finding such a large deposit in one place.
An ore is a naturally occurring material from which a metal or valuable mineral can be extracted, while a lode is a deposit of ore found in a fissure or crack within a rock formation. Essentially, a lode is a layer or vein of ore within a larger mineral deposit.
This is false. A lode is not a layer of minerals that has been deposited in a stream. A lode is formed by hot mineral solutions going into the cracks of the rocks.
The Mother Lode is located in the Sierra Nevada mountain range in California. It is a region known for its rich deposits of gold and played a significant role in the California Gold Rush.
Reef gold: this gold will become smoother the further away it is from the source, the source being the reef. If the gold is jagged in appearance then the gold source is near! Alluvial gold, river gold, placer gold: this gold will reduce in quantity the further away it is from the mother lode. If your recovering kilograms of alluvial gold in one spot, then you are on the gold! Next trick is to find the reef gold that deposited the alluvial gold!
Gold is recovered by three basic mining methods: placer mining of alluvial deposits, lode or vein mining, and recovery as a by-product of base-metal mining.
Placer mining was largely replaced by hydraulic mining and hard rock mining methods. Hydraulic mining used high-pressure water jets to extract minerals, while hard rock mining involved digging tunnels and shafts to access mineral deposits underground. These methods were more efficient and able to extract minerals from deeper beneath the surface.
This category covers establishments primarily engaged in mining gold ores from lode deposits or in the recovery of gold from placer deposits by any method.

Gold can be found in every country in the world. However the placer deposits and lode ores in many places are not economical to actually mine.
