Because of its high cost of production, river pebble mining could not compete with land pebble and hard rock. As a result, river pebble production, which peaked in 1893, ceased entirely by 1908. Hard rock mining, which dominated the early years of the industry, also had high production costs relative to land pebble.

Russia has vast platinum reserves and is a leading palladium producer. 17% of the world's nickel production is controlled by Russia. Russia's largest metals and mining company Norilsk Nickel controls the production of palladium, nickel and copper. In 2008, Norilsk Nickel had produced 300,000 tons of …
Mining in a wider sense includes extraction of any non-renewable resource, including petroleum, natural gas, bromine brine, or even water. These resources are recovered by extractive methods that differ from those of normal surface or underground "hard rock" mining methods.
Pebble Mine is the common name of a mineral exploration project investigating a very large porphyry copper, gold, and molybdenum mineral deposit in the Bristol Bay region of Southwest Alaska, near Lake Iliamna and Lake Clark. The proposal to mine the ore deposit, using large-scale operations and infrastructure, is controversial.

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.
The mines are in wet regions near rivers and much of the mining consists of picking through the river beds and using shovels and pickaxes to break away rock and dig through to the areas where the pegmatite can be found.
