The commerce and industry ministry did not immediately reply to a request for comment.
A spokesperson for First Quantum declined to comment.
The government and the mining company have been discussing a deal that would have increased annual tax payments to Panama to at least $375 million.
The Panamanian government ordered the firm to halt operations at the Cobre Panama mine after they both missed a deadline to reach an agreement.
The firm started arbitration proceedings against the government days after, according to local authorities.
A government official said last week the country was looking for a “fair” deal.
The mine accounts for roughly 3.5% of Panama’s gross domestic product, according to government figures.
