ROCA - MAX Molybdenum Mine Production Schedule

 Vancouver, British Columbia: Roca Mines Inc. (TSX-V: ROK) ("Roca" or "the Company") announces that mine development work at the MAX Molybdenum Mine has advanced positively in June 2011 and crews are nearing re-start of production.

The geotechnical monitoring program is nearing completion with the installation this week of new instruments. This will enhance existing geotechnical monitoring, which to date shows no changes to the stability of the workings or mine access. This final step in the mine's rehab program will allow for monitoring of the new 750 sill pillar and of the 830 level rib pillar on a daily basis, these two areas being of primary interest once production recommences.

The mine's development contractors were mobilized in May 2011 and have been preparing the underground mobile equipment, developing and sampling new headings, upgrading ventilation components and generally preparing for underground production re-start. The mine's longhole production drilling contractor mobilized last week to commence production drilling; the development of a slot raise (the first phase of stope production) is now complete. In addition, various contractors are reorganizing staffing for the mill and other operations at site. Further updates on production will be provided as various tasks are completed in the near term.

Management's goal to restart production at the MAX molybdenum mine and to advance its permitted 1,000-tonne-per-day expansion plans will reduce unit costs and preserve the opportunity to produce concentrates in an appreciating price environment. Molybdenum oxide currently trades at approximately US$15.50 per pound.
