PANAMA CITY, Jan 10 (Reuters) - Panama's government on Tuesday doubled down on an order that Canada-based miner First Quantum Minerals (FM.TO) halt operations at its local copper mine, saying the miner had been operating without a contract since 2017. Earlier, First Quantum said it would submit an appeal against Panama's order by the end of the day. On Tuesday, Panama's commerce and industry ministry said First Quantum had been operating without a contract after the previous one was annulled by the Supreme Court in 2017. That court ruling was published in the government's official gazette in December 2021, but First Quantum continued operating as a new deal was negotiated. First Quantum's Chief Executive Tristan Pascall said in a call with investors on Tuesday morning that following the Supreme Court decision, the government of Panama issued public statements "reaffirming that the contract remained valid."
