(Adds comment from Cochilco, details)
By Antonio de la Jara
SANTIAGO, March 31 Chile, which provides about
a third of the world's copper, produced 423,201 tonnes of the
metal in February, up 8.0 percent from the same month last
year, the government's National Statistics Institute said on
Chilean copper output totaled 439,123 tonnes in January.
"The increase in copper production is due mainly to
'Category A' firms (which have more than 400 workers), which
accounted for 89.6 percent of the increase," INE said in a
Copper cathode output rose 1.1 percent during the period to
193,651 tonnes, while copper concentrate output rose 2.4
percent to 200,689 tonnes.
The output increase marked a reversal from recent months.
Output had fallen each month since October.
State copper commission Cochilco attributed the increase to
a lower base of comparison in 2007 and an extra day of
production this February due to leap year.
"All the firms which come into that category, which are the
biggest, and there are several, nearly all increased production
during the period," Raul Acevedo, head of Cochilco's economic
studies department, told Reuters.
"The month of February had another work day this year
compared to last," he added, saying the extra day could imply
an output increase of around 3 percentage points alone.
"Also, last year some firms had output that was below the
norm because of technical difficulties ... so this year looks
Chile is by far the world's largest source of copper, a
metal used in electrical wiring, plumbing, heating, air
conditioning, roofing materials and car radiators, among other
Chile produced 5.588 million tonnes of copper in 2007, a
rise of 3.8 percent over the previous year.
However, Chile's state-owned Codelco, the world's top
copper producer, said last month it produced a total of 1.583
million tonnes of the metal last year, not including its stake
in the El Abra mine, down 5.5 percent from 1.676 million tonnes
Including the El Abra mine, Codelco said, it produced 1.665
million tonnes of copper in 2007, compared with 1.783 million
tonnes in 2006.
Codelco's output has receded in recent years as ore grades
have fallen at its aging mines. In 2007, it was also hit by
supply disruptions from a month-long subcontractors' strike
across its divisions.
For 2008, Codelco estimates output at all its divisions
will be similar to last year. It expects start-up of its mine
Gabriela Mistral to offset an expected shortfall at other
divisions due to lower ore content.
Molybdenum output rose 4.3 percent in February from the
same month last year to 2,834 tonnes, INE said. Chile is a top
producer of the metal, which is used in high-strength steel
Prices for copper and molybdenum are near historic highs on
global markets and have helped push up Chile's trade surplus to
record levels in recent years.
