JAKARTA, Oct 14 (Reuters) - Miner Freeport Indonesia may

be forced to suspend operations at its Manyar smelter at the end

of October due to a lack of copper concentrate following a

mud-flow incident at its Grasberg mine, media outlet Kontan

reported on Tuesday, citing an energy ministry official.

Freeport Indonesia did not immediately respond to a request

for comment.

Tri Winarno, an official at the country's mining ministry,

estimated that copper concentrate supplies from Grasberg would

only be sufficient until the end of this month, Kontan reported.

"(Freeport) will face a lack of supply by the end of

October. Temporarily halted," Tri told reporters.

The mud-flow disaster had killed seven workers and

operations at the Grasberg mine have been halted for nearly a

month.

Grasberg may not return to its pre-accident operating

rates until at least 2027, the company had said.

The $3.7 billion Manyar smelter only resumed operations

in May after a fire broke out in October last year, damaging the

plant.
