A plan to extend the life of a major mine to 2050 has been described as the "largest coal-mining proposal ever put forward" in NSW with warnings steep cuts to other sectors' emissions will be needed to compensate.
The proposal to continue Hunter Valley Operations, a joint venture between Glencore and Yancoal, would produce an extra 437.6 million tonnes of thermal coal and 59.7 million tonnes of metallurgical coal for export.
