• The Big Hole a former diamond mine in Kimberley, dug to 240 m (790 ft) between 1871 and 1914, making it the deepest hand-excavated pit in the world. Now a museum.• The Jagersfontein Mine operating between 1888 and 1971. This was hand-excavated to 201 m (660 ft) by 1911, and the hand-dug pit was sightly larger than the Big Hole.
Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).
As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesn’t require tunnelling into the earth and is a simple method of mining that yields high production rates.
