Elk Coal Mine

TORONTO, June 21 /CNW/ - Cline Mining Corporation (TSX: CMK) ("Cline" or the "Company") is pleased to announce that the underground miners have now completed the installation of roof support and clean-up of roof falls in the Access Slopes down to the Allen seam, the lowest coal face at Cline's New Elk Coal Mine located in Las Animas County, Colorado, U.S.A. This completes the rehabilitation of the Access Slopes, which intersect all three mineable coal seams in the deposit. These are the Allen, Maxwell and Apache coal seams, which contain a total of 315,000,000 tons of National Instrument 43-101 ("NI 43-101") compliant measured and indicated coal resources. Work is currently underway to prepare the Access Slopes for a mine development phase including installation of conveying and hoisting systems. The Company is pleased with the progress and that it is now presented with full flexibility and all options to best exploit the coal resource.

First production at Cline's New Elk Coal Mine is planned for Q4 of 2010. Production will ramp up to 1.3 million tons per year in 2011, and thereafter increasing to 3.0 million tons annually by 2013 of metallurgical steel-making coal slated for world markets. Cline's New Elk Coal Mine has a measured and indicated coal resource of 315 million tons of in-place coal as documented in the 2008 Behre Dolbear independent NI 43-10 Technical Report.

Both reports are available on SEDAR and Cline's website at www.clinemining.com.
