Indonesia to Review Compliance in Move That Could Affect Mine Output, Official Says

MINERAL COMMODITY - JAKARTA. Indonesia will check miners' compliance with environmental rules and other regulations and "reexamine" production quotas for those found to be in breach, a senior mining official said on Friday, amid efforts to ensure the sustainability of its reserves.

Indonesia's vast natural resources include copper, gold, tin and nickel, and miners are granted annual production quotas under a document known as an RKAB, which is valid for three years.
