Vale Inco restarts Thompson nickel ops

* Maintenance shuts Thompson, Manitoba, for month

* Strikes at Sudbury, Voisey's Bay continue

* Company plans to restart some Sudbury mining

TORONTO, Sept 14 (Reuters) - Vale (VALE5.SA) Inco has restarted its Thompson, Manitoba, nickel mining and processing operations following a one-month maintenance shutdown, a spokesman said on Monday.

The restart comes as 3,100 workers remain on strike at the company's main nickel hub of Sudbury, Ontario, while smaller strikes continue at its Port Colborne, Ontario, operations, and the Voisey's Bay mine in Newfoundland and Labrador.

Vale, which bought the assets when it took over Inco in 2006, has said it will restart part of its copper and precious metal mining in Sudbury using workers from other departments, but has not yet done so, said company spokesman Cory McPhee.

"We are still in the process of training in preparation for resuming partial production. That process has not yet begun nor are we committing to any definitive timeline at this point," he said in an email.

McPhee said that no talks were scheduled.

The strikes at Sudbury and Port Colborne began on July 13, while the Voisey's Bay strike began at the beginning of August. (Reporting by Cameron French; editing by Rob Wilson)
