Chile’s mining woe supports copper prices
“Declining ore grades” is not a phrase to set the heart aflutter. Even investors in the metals and mining sector may struggle to get excited about the subject after years of hearing it being deployed as a justification for higher prices.
But the issue has rarely been such a potent force in the market. The fall-off in ore quality at ageing mines is behind a stagnation in copper production in Chile, the world’s top miner of the metal with a third of global output, since 2006.
The start of this year has seen an acceleration of the trend: Chilean copper production was down nearly 8 per cent year on year in January, and by about 20 per cent from December.
That is a shockingly large number. To put it in context: the drop in Chilean production in January is equivalent in terms of its impact on the copper supply-demand equation to a 5 percentage point acceleration in Chinese consumption growth.
Analysts have been scratching their heads ever since the headline numbers were reported a fortnight ago by INE, Chile’s statistics institute, to determine what could be behind the sharp decline.
The grim reality is that no single factor drove the fall: instead, according to mine-by-mine data recently published by Cochilco, Chile’s state copper commission, nearly every large mine in Chile suffered a fall in production in January from December. Most of Chile’s largest mines saw double digit percentage falls in output year on year.
