(Kitco News) - Nippon Dragon Resources said Monday it is restarting development work at its Rocmec gold property located in Quebec.

The company will use thermal fragmentation technology, a mining method that economically mines narrow vein deposits. The mining method produces "highly concentrated ore which results in 400% to 500% less dilution," said the company on its website. The method use drilling and high heat to turn targeted hard rock deposits into sand, which is vacuumed out for processing.

"The extraction process allows thermal fragmentation with an accuracy of 2 cm to quickly extract any type of hard rock up to 110 cm wide. With such precision, high grade precious and base metal veins can now be extracted without dilution. The thermal unit can be set up to extract a specific corridor."

The Rocmec property was acquired in October 2005. Dewatering and rehabilitation of the mine commenced in January 2006. To date, Nippon Dragon has invested approximately C$33 million in development work.

The company updated its reclamation plans. At Rocmec, the portal is being opened and dewatering is about to start.
