Regardless of the type of raw material, its extraction always comes with an environmental cost. Most mining leaves a lasting and damaging environmental footprint. For example, during the extraction of common metals like copper, lead or zinc from the earth both metal-bearing rock, called ore, and āoverburdenā, the dirt and rock that covers the ore are removed. At a typical copper mine around 125 tonnes of ore are excavated to produce just one tonne of copper. The amount of earth moved is mind-boggling and mining now strips more of the Earth's surface each year than does natural erosion.

Downcast shaft at Daw Mill colliery in Warwickshire. This is the largest colliery in the UK, mining a five-metre thick section of the Warwickshire Thick seam some 750 metres below the ground. The shafts here are 558 metres and 556 metres deep. In 1982, a drift was completed and all coal is now brought out this way.

Butte, Montana was known as the āRichest Hill on Earthā for its gold, silver and copper deposits. This photograph was taken in 1983. Most of the mines had played out. Scores of mining apparatus dotted the landscape. Below ground many miles of tunnels were sealed off and abandoned.

Compared to many open pit operations, Hanna Nickel used small shovels and trucks. I believe these we 75 ton trucks and the shovels were not very large compared to the iron ore operations and coal operations I had the privilege to be associated with. The ore content was about 1% nickel and there were truck mounted analysis labs that tested the ore content of what was being mined. If "higher" grade ore was found in a pocket it was mixed with lower grade ore to allow a consistant product to be sent to the smelting operation at the bottom of the hill.
Iron ore mining operations can be viewed from above at the Hull-Rust-Mahoning Mine. These trucks are huge.

I built this MOC for Andromeda's Gates on Eurobricks. It shows a MANTIS mining base in full swing, there's even some little loader trucks carrying loads of Awesomnium. The building has a full interior as well.

Eureka is a museum of mining history. Situated on highway 50 about halfway between Austin and Ely, few other towns offer as much to the curious visitor as does Eureka. The year 1864 saw the discovery of lead-silver deposits as spectacular as any in the country. But there was a problem. Bi-metallic ore required refining methods and techniques not yet developed. The first plant built in 1869 was a failure. Another was built that was more successful and was the forerunner of even more advanced methods. The boom then began in earnest and continued until there were nearly 10,000 people in the town. About the time production began to decline, a railroad was brought into Eureka. Because of the town's central location in the state, it became a railhead for the whole area.
