According to a Reuters report, heavy rainfall in
southeastern Brazil has prompted miners including Vale SA to suspend some
operations after downpours caused deadly floods in the northeast.
Rainfall is
expected to remain heavy this week in most of top mining state Minas Gerais,
after runoff closed roads and railways.
The rains may also have contributed to the dramatic
collapse of a canyon rock face in the state on Saturday, killing 10 people
visiting a waterfall on boats.
In the northeastern state of
Bahia, flooding displaced about 50,000 families and killed some two
dozen over the holidays.
Vale said on Monday it has partially suspended operations at
its Southeastern and Southern iron ore systems due to the bad weather, but
reaffirmed its 2022 production target as the Northern system was not affected.
Samarco, a joint venture between Vale and BHP also cut back
operations in its Germano complex, producing at an estimated 50% of capacity
until weather allows it to ramp up.
Brazilian steelmakers Usiminas and Companhia
Siderurgica Nacional (CSN) also halted operations of their mining units.
Anglo American said its Minas-Rio system continued to
operate as planned during the rainy season.
Over the weekend, France's Vallourec suspended production
from its Pau Branco mine after heavy rainfall caused a dike to overflow.
"We see the news as potentially negative for the entire
mining sector, as it could result in new regulations to suspend existing
operations or delay new projects," analysts at XP Investimentos said in a
research note.
BTG Pactual analysts said economic impacts could be muted if
normal operations are restored quickly, but noted it all depends on how long the
heavy rainfall will last.
"We estimate there could be more than 100 million tons
of annualized iron ore supply at risk at this stage in Brazil, which is a
relevant number ‑ roughly 7% of seaborne supply and about 30% of Brazilian
supply ‑learly the stakes are high and we could see impacts on short-term iron
ore movements," they said.
INTERRUPTED RAILWAYS, CLOSED HIGHWAYS
Vale said in a securities filing that train circulation at
its Vitoria-Minas railway was partially interrupted by the rains, halting output
at the Brucutu mine and the Mariana complex due to a lack of transportation.
Both mines are part of Vale's Southeastern system, along
with the Itabira complex, where production was not affected.
In the Southern system, Vale said all of its complexes had
to halt production because key highways BR-040 and MG-030 were closed.
Vale said its Northern System is still operating as planned,
and maintained its 2022 iron ore production forecast at 320-335 million tons.
It noted its production plan takes into account the seasonal rainfall impact.
The miner also said the rains had not changed the alert
level for any of its tailing dams which are under constant,
"real-time" monitoring.
"While Vale did not change its production guidance for
2022, we believe that the market could start to project volumes closer to the
low end of the range," Itau BBA analysts said, noting that iron ore prices
could be supported at their current high levels.
Vale's two halted operations accounted for about 31% of its
output in the first nine months of 2021, the Itau BBA analysts said. A two-week
halt in these operations could represent an impact of about 3 million tons for
the company, according to their preliminary calculations.
Steelmaker Usiminas announced a stoppage at its mining subsidiary
Mineracao Usiminas (MUSA) due to weather, but said it had enough inventory of
raw material to avoid disruption.
The company also said its Barragem Central tailings dam,
which has been inactive since 2014, reached alert level 1 - an initial warning that
does not mean a safety breach was noted.
CSN and its steel mining subsidiary CSN Mineracao SA announced
a halt to operations of the Casa de Pedra mine, but said they are expected to
resume in coming days.
They said port operations at the Itaguai coal terminal,
located in the neighboring state of Rio de Janeiro, were also suspended due to
excessive rains.
Brazil's regulatory National Mining Agency (ANM) suspended
operations at French steel pipe maker Vallourec's Pau Branco iron ore mine in
the state after a dike overflowed, cutting off a federal highway. There were no
reported injuries.
"After the dam incidents of the past, we welcome the
zero tolerance approach that miners are taking in the country to minimize
operational risks, which we consider the prudent approach," BTG Pactual
said.
