The 2014 operations focus was on ramping up the stage 3 project and delivering 1.9-2.1 million tonnes of production by targeting the Greta seam. The Greta seam is 400-600m below the surface. "This is the result of more than four years work to bring this new mining area into production and marks a significant milestone for the Austar mine," Yancoal said in its annual report. "Significant planning and investment, including upgraded infrastructure and logistics, have been made to deconstrain the operation and help achieve more consistent production and minimise inherent risks."
