Open cut mining began at Ensham in 1993, and in 2011, the operation began underground mining as well. Historically, the mine has produced great quantities of coal per year — as of 2009, the mine had produced over 80 million tonnes of coal. By some estimations, over a billion tonnes in total resource still remain at the Ensham mine.[1] However, an estimate of the mine’s recoverable reserves was not available.

Throughout the mine’s history, annual production has varied between 8 million tonnes of coal per year and 5 million tonnes of coal per year.[2] [3] Before the early 2010s, production was higher, but falling coal prices caused the company to downsize its operations.[1]

According to an ABC News report, mining is schedule to take place at Ensham mine until 2028. The article also pointed out that Ensham mine is one of the first large open-cut mines subject to new legislation that requires miners to rehabilitate land progressively as they mine.[4]
