Mineral Reserves that will be mined by open pit methods and Mineral Reserves held in stockpiles assume a conventional open pit mining method, gold price of US$1,350/oz, metallurgical recovery of 98 , selling costs of US$57.44/oz including royalties and levies, average mining cost of US$2.29/t mined, average processing cost of US$12.26/t processed, and site general costs of US$3.15/t
Open pit is one of themon mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.

Gold is generally extracted in open pit mines at 1 to 2 ppm parts per million but in certain cases, 0.75 ppm gold is economical. This was achieved by bulk heap leaching at the Peak Hill mine in western New South Wales, near Dubbo, Australia. Nickel, generally as laterite, is extracted via open pit down to 0.2 .

Open pit mining, where material is excavated from an open pit, is one of themon 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.
Surface mining, method of extracting minerals near the surface of the Earth. The threemon types of surface mining are open pit mining, strip mining, and quarrying. See also mining and coal
The Company currently plansmence open pit mining at Wolfshag in 2016. The conceptual plan would be to blend higher grade material from Wolfshag with ore from the Otjikoto pit resulting in an increase in annual gold production at Otjikoto and improved project economics.
Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining is the preferred method for mining gold, silver, and uranium. This type of mining is also used to dig for coal and building stone.

Barrick Gold Corporation has one of the largest open pit gold mines in North America located on its Goldstrike mine property in northeastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres 12,800 ft underground. At such depths, the heat is unbearable for humans
Its material mineral properties consist of three mines and one mine under construction: Otjikoto mine, an open pit gold mine located approximately 300 kilometers north of Windhoek, the capital of
Hard rock mining is the process of using open pit or underground mining tunnels to retrieve the gold from the rock. This method of gold mining is responsible for recovering most of the worlds gold supply. Byproduct mining is related to hard rock mining in that open pit or underground mining tunnels are used.

Open pit mining, also known as open cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.
