Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model.There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
It is currently the highest producing copper mine in the world. Its 2007 production of 1.483 million tons of the metal was worth US$10.12 billion, [1] mainly as metal in concentrate, but some as cathode, and was 9.5% of world output and 26% of Chilean production, according to the US Geological Survey's preliminary estimates of 2007 world mine ...
The ore deposit type is Polymetallic veins of hydrothermal origin. The mining method used is underhand cut and fill mining. [3] The mine's primary access and production are through the Silver Shaft, an 18-foot (5.5 m) diameter, concrete-lined shaft sunk to a depth of 6,200 feet (1,890 m), [4] [5] [6] over 2,800 feet (855 m) below sea level.
One estimate of land ore mining reports that it will lead to a loss of 568 megatons of biomass (approximately the same as that of the entire human population) [90] versus 42 megatons of biomass from DSM. In addition, land ore mining will lead to a loss of 47 trillion megafauna organisms, whereas deep-sea mining is expected to lead to a loss of ...
The Orebodies 18, 23 and 25 mine, part of BHP's Eastern Ridge hub and officially referred to as the Newman East operation, [1] is an iron ore mine located in the Pilbara region of Western Australia, 8 kilometres east of Newman. [2]
Kidd Mine or Kidd Creek Mine is an underground base metal (copper-zinc-silver) mine 24 km (15 mi) north of Timmins, Ontario, Canada. It is owned and operated by Swiss multinational Glencore Inc. The ore deposit was discovered in 1959 by Texas Gulf Sulfur Company. Exploration drilling at the Kidd site began in November 1963.

The trucks haul ore from the shovel to primary crushers. Crushed ore is sent by a conveyor 1.8 m (6 ft) wide and 6.8 km (4.2 mi) long to the mill. Daily production from the mine is an average of 600,000 t (660,000 short tons) ore and waste combined. Ore from the mine has an average copper grade of 0.49% and an average gold grade of 0.39g/t. [3]
