With
technology and expensive metal worldwide, Brazil’s gold production will double,
attracting investments of US $ 2.4 billion.
Large
international mining companies invest heavily in technology and explore areas
previously considered uneconomical.
CRIXÁS
(GO) and Brasilia - Four centuries after the gold cycle that filled the eyes of
the Portuguese Crown and prompted Brazilians and foreigners on a quick gold
rush, Brazil is facing the biggest race of all time for this metal. New
sophisticated equipment allows foreign giants, which dominate the domestic
market to tap into what might be called "the pre-salt of the mining sector".
Mines in the Center-West and North parts of Brazil, as well as in other areas
hitherto considered exhausted and or untouched in Minas Gerais and in the
Northeast have become now economically viable,.
All
this thanks to the increased gold demand in the entire planet — with price
quotation surge of 540% in the last decade — stimulated by world economic
growth, mainly from China, and by the need of countries to stock up the metal,
which is considered one of the world's most trusted financial
assets.
Metal
is found at depths of over 8,202 feet in Brazil
The
enthusiasm is such that the Brazilian Mining Institute (IBRAM) estimates
investments to top US$ 2.4 billion in the sector until 2015. It is almost triple
the previous projection of just over US$ 900 million. The mining companies do
not hide their optimism and promises new projects, while the authorities
estimate that gold production shall also grow strongly and may double over the
next five years. Only in the Rio Grande do Norte State, production shall jump
form 60 grams to six tons if all projects materialize.
Brazil
has currently about legal 2,819 “garimpos” (manual gold prospecting
areas) in operation. However, the National Department of Mineral production
(DNPM) has awarded 1,270 new search permits in areas to be explored, and is
considering more 1,173 requests filed by companies and
cooperatives.
If
the 2008 global financial crisis imposed slowed down developed countries’
economies, which in theory, would reduce the demand for gold, it ended up
helping to devalue the U.S. Dollar and put pressure on gold prices, historically
considered a safe haven by investors. World central banks never bought so much
gold to beef up their international reserves since the Decade of the 80’s.
The price escalation made new millionaire investments viable in research and
technology.
In
the past, gold gushed forth from the Earth, or from rivers, and collecting or
mining it did not require much effort. Today, it is being found at depths of up
to 13,123 feet in South Africa, but is already in 8,202 feet in Brazil.
Sophisticated machines are able to extract less than a gram of gold from a ton
weighing rock, i.e. something equivalent to the size of a car.
This
explains why Brazil, which already was the world's largest producer, but lost
positions in the recent past, have come back to the game, and is in the 13 place
in a list of major global suppliers. In 2010, Brazil produced 62 tons through
its legal garimpos, the largest volume of the Decade, and is preparing to double
this number. The world's largest producer is China with 341 tons/year, followed
by Australia (259 tons), United States (240 tons) and South Africa (192
tons).
The
Brazilian production is very small of only 12% of its potential. Considering the
proven reserves in 2010, Brazil has the annual extraction capacity of 503 tons
of pure metal. The amount was calculated based on 1.3 billion tons of rocks with
the ore, with an average of 2.57 grams per ton of rocks.
Technology
can lead the country to the top
The
expectation of the Government and of specialists is that technologies should
change this scenario and can take Brazil to the top of the list once again.
Instead of the traditional handpicking goldfields that filled Brazilian rivers
with deadly mercury, the country already has 93.7% of its production done
mechanically, according to the DNPM (National Dept. of Mineral Production). Iron
ore remains the most important item in the Brazilian trade balance and
corresponds to more than 80% of what the country sells out there, but the second
metal is gold, with almost 5% of the total.
In
Crixás, North of Goiás State, Mineração Serra
Grande, a joint venture between AngloGold Ashanti, South Africa, with Kinross
Gold Corporation, of Canada, already works at 2,296 feet, with tunnels, reaching
a total of 37.8 miles long. The company’s plans, which owns the deepest
mines in Brazil, both in Minas Gerais (Mina Cuiabá, Sabará, with
3,281 feet, and Mina Grande, in Nova Lima, with 8,202 feet), can be measured by
their investment plans.
The
company's Operations Director, Mr. Ricardo de Assis, claims that US$ 1.1 billion
will be invested in new projects, expansion and maintenance of the mines in the
country. Anglo is the second largest producer in Brazil and the third in the
world.
Not
far from Crixás, Paracatu is the largest open pit gold mine in the
country, operated by Canadian Kinross. To get to the metal, the company had to
invest in technology that allows it to get 0.4 gram of mineral per ton of rock.
Over the past five years, according to the company's Vice President in Brazil,
Mr. Antonio Carlos Marinho, production jumped from five to 15 tons.
At
the mine in Sao Francisco, in Rio Grande do Norte State, Australian Crusader is
completing surveys initiated a year ago and aims to produce three to five tons
per year in this place, where few saw potential in the past. The expectation is
that the gold content is 1.5 gram per ton, according to the executive
responsible research, Mr. Rob Smakman, who lives in Brazil for a few years with
the family and has led the company's work in the country.

This is a little exploited region — said Smakman.
