Alluvial or placer gold is usually found close to the Earth's surface and can thus be accessed more easily. Conventional hard rock mining can be considered profitable from about 1 g of gold per tonne of rock, but mining alluvial gold can be economical from as little as 0.3 g per cubic metres of gravel.
