The Cuiab#225; mine will increase its gold production by 50 percent and simultaneously increase the production of sulphuric acid, a byproduct, from 130,000 tonnes per year to 150,000 t/y. This will represent an increase of 50 percent in revenue during the first four years as well as an extension of the operating life of the mine from 2013 to 2019.

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on
