Coalspur Mines Ltd shares advanced after the company bankable feasibility study for its Vista coal project in Alberta will show a 24% increase in likely annual production.

Production is seen rising from 9 million tonnes yearly as predicted in the company pre feasibility study to 11.2 million tonnes per year in the new guidance.

The miner said the ongoing positive results illustrate the Vista potential to become Canada's largest exporter of thermal coal, adding the bankable study is progressing on schedule and will be ready for publication in early 2012 following completion at the end of 2011.
