Panama's President Mulino has failed to issue a decision on the fate of the shuttered Cobre Panama mine, letting a self-imposed June deadline pass without resolution.

The delay comes despite an external audit delivered on June 19 that found the mine roughly 88% cleared, according to reports from The Rio Times.

The lack of a definitive ruling keeps the world's largest copper mine offline, prolonging uncertainty for investors and the global supply chain.

The mine, operated by First Quantum Minerals, was closed earlier this year following a Supreme Court ruling that voided its operating license on environmental grounds.

Markets have been closely watching Panama for signs of a potential reopening or a new licensing framework.

The continued stalemate suggests that political and environmental considerations remain significant hurdles, even with the technical audit largely complete.
