Private firms that invest in gold mining in Brazil will allocate about $2.4 billion over the next four years to their activities, the O Globo newspaper reported Sunday, citing official figures. This volume of investments is three times the earlier forecasts for the period and could be a major factor in doubling the country's production of the precious metal, which currently stands at 62 tons per year. The figure places Brazil in 13th place among gold mining countries, a good bit below the top-ranked countries, which are China (341 tons per year), Australia (259 tons), the US (240 tons) and South Africa (192 tons). The National Department of Mineral Production has just granted 1,270 permits to mining companies to prospect for gold and is analyzing another 1,173 applications of this kind, the newspaper said, adding that the increase in permit requests is like ‘a new gold race'. Brazil currently has 2,819 legal and active gold mines, according to O Globo, although most of the production is concentrated in just a few mines operated by foreign mining firms. The largest gold mine in the country is located in Paracatu, a town in the central state of Minas Gerais, and it is run by Canada's Kinross. Over the past five years production at this mine has tripled to 15 tons per year, a feat that has demanded a great technological effort because Paracatu is one of the mines with the lowest purity index of the precious metal, just 0.4 grams of gold per ton of rock. Brazil is only operating at 12 percent of its gold production capacity, which could reach 503 tons per year if the country's proven reserves are taken into account, O Globo said.
